    Effects of pig and dairy slurry application on N and P leaching from crop rotations with spring cereals and forage leys2014In: Nutrient Cycling in Agroecosystems, ISSN 1385-1314, E-ISSN 1573-0867, Vol. 98, no 3, p. 281-293Article in journal (Refereed)
    Abstract [en]

    Two crop rotations dominated by spring cereals and grass/clover leys on a clay soil were studied over 2 years with respect to nitrogen (N) and phosphorus (P) leaching associated with pig or dairy slurry application in April, June and October. Leaching losses of total N (TN), total P (TP), nitrate-N and dissolved reactive P (DRP) were determined in separately tile-drained field plots (four replicates). Mean annual DRP leaching after October application of dairy slurry (17 kg P ha-1) to growing grass/clover was 0.37 kg ha-1. It was significantly higher than after October application of pig slurry (13 kg ha-1) following spring cereals (0.16 kg ha-1) and than in the unfertilised control (0.07 kg P ha-1). The proportion of DRP in TP in drainage water from the grass/clover crop rotation (35 %) was higher than from the spring cereal rotation (25 %) and the control (14 %). The grass/clover rotation proved to be very robust with respect to N leaching, with mean TN leaching of 10.5 kg ha-1 year-1 compared with 19.2 kg ha-1 year-1 from the cereal crop rotation. Pig slurry application after cereals in October resulted in TN leaching of 25.7 kg ha-1 compared with 7.0 kg ha-1 year-1 after application to grass/clover in October and 19.1 kg ha-1 year-1 after application to spring cereals in April. In conclusion, these results show that crop rotations dominated by forage leys need special attention with respect to DRP leaching and that slurry application should be avoided during wet conditions or combined with methods to increase adsorption of P to soil particles. © 2014 Springer Science+Business Media Dordrecht.

    Screening the working environment in outdoor pig systems2009In: Journal of Agricultural Safety and Health, ISSN 1074-7583, Vol. 15, no 3, p. 283-297Article in journal (Refereed)
    Abstract [en]

    This study investigated how well organic growing-fattening pig systems provided a safe and healthy working environment and identified areas where improvements are needed. The study formed part of a larger project aimed at identifying strategies for creating a good animal and working environment and resource-efficient nutrient management in outdoor pig systems. Field studies were carried out at six Swedish farms in two types of outdoor pig systems (mobile and stationary). A method known as WEST (Work Environment Screening Tool) and a modified version of WEST, called WEST-agriculture (WEST-AG), were utilized for screening. Together, the two methods covered six factors of the working environment. The results were expressed in WEST-AG points and WEST points, an economic measure of the risk of impacts on health and productivity expressed as Swedish Krona (SEK) per thousand working hours. The results demonstrated that the risk of injury and ergonomic load during manual feeding and watering was much higher than during semi-automatic feeding and watering at farms with the mobile system. The study also identified other health-risk areas and provided valuable information for further improvement of the working environment in different outdoor pig systems. © 2009 ASABE.

    Barn balance calculations of Ca, Cu, K, Mg, Mn, N, P, S and Zn in a conventional and organic dairy farm in Sweden2007In: Agriculture, Ecosystems & Environment, ISSN 0167-8809, E-ISSN 1873-2305, Vol. 119, no 1-2, p. 160-170Article in journal (Refereed)
    Abstract [en]

    Calculations of flows and balances of plant nutrients in agricultural production systems provide some basic information for the assessment of their long-term sustainability. The objectives of this study were to assess the possible impacts of variations in element concentrations between years and of undefined sinks and sources of elements on the accuracy of balance calculations. A 3-year study was conducted on Ca, Cu, K, Mg, Mn, N, P, S, and Zn fluxes in the barns (subsystem) of a Swedish farm with separate conventional and organic milk production. Our main focus in this subproject was on barn balance calculations, the barn housing only cows. Barn balance for an element was defined as amount of that element in [feeds, heifers, bedding, water] - [milk, manure, urine, calves, culled cows]. The focus was on: (1) variations in element concentrations in the main flow carriers [feeds, milk, manure, urine]; (2) information about element dynamics and flows of dairy farming systems obtained from internal flows of elements in the barn balance compared with that obtained from the flows associated with milk production in a farm gate balance; (3) differences in element flows and concentrations between the organic and conventional farming systems on this farm. Our conclusions were: (1) the sampling methods used had low coefficients of variation and thus pooled samples can reduce the costs of element analyses. However, urine must be thoroughly mixed if less water-soluble elements are to be monitored. Magnesium differed significantly in concentrations between years in all feedstuffs; (2) year-to-year fluctuations in harvest can influence a calculation negatively if calculations are based on annual harvest and not on feed supplied. The barn balance calculation showed a source of Cu, Mn and Zn that would not have been obvious in a farm gate balance. The element content of manure and urine calculated as [inputs - milk] would have underestimated the amount of Cu, Mn and Zn in manure and overestimated the amount of K and N. The Cu analysis showed an example of conflicting goals between short-term welfare of the cows and long-term soil fertility. EU legislation regarding land for spreading of manure is not a guarantee against soil contamination by heavy metals; (3) the differences between the organic and conventional system related more to differences in forage: concentrate and home-grown: purchased ratios, which were typical for the average Swedish farm of each type, and less to differences in element concentrations of the feed ingredients. © 2006 Elsevier B.V.

    Lönsam stallgödselhantering: teknik, växtnäringshushållning, kvalitet och ekonomi2002Report (Other academic)
    Abstract [sv]

    För att inte skada miljön måste växtnäringen i stallgödseln tas tillvara och återföras

    till de odlade grödorna. Skälen till att använda stallgödsel är dock fler. Dyrare

    mineralgödsel och ekonomiskt kärvare tider har bidragit till att det ur ekonomisk

    synvinkel blivit mer intressant att använda stallgödsel som växtnäringskälla.

    JTI har, på uppdrag av SLA, sammanställt sin stallgödselforskning, bland annat med

    utgångspunkt från lantbruksföretagarens behov och frågeställningar. Hur kan man

    utnyttja växtnäringen optimalt? Hur ska gödseln lagras? Vilken utrustning och tidpunkt

    är lämpligast för spridning? Vilka givor ger bäst avkastning och kvalitet på

    gröda? Vad kostar jordpackningen och hur kan den minimeras?

    Här förmedlas konkreta tips och råd kring stallgödselhantering.

    A systems approach to assess farm-scale nutrient and trace element dynamics: A case study at the Öjebyn dairy farm2005In: Ambio, ISSN 0044-7447, E-ISSN 1654-7209, Vol. 34, no 4-5, p. 301-310Article in journal (Refereed)
    Abstract [en]

    A systems analysis approach was used to assess farmscale nutrient and trace element sustainability by combining full-scale field experiments with specific studies of nutrient release from mineral weathering and trace-element cycling. At the Öjebyn dairy farm in northern Sweden, a farm-scale case study including phosphorus (P), potassium (K), and zinc (Zn) was run to compare organic and conventional agricultural management practices. By combining different element-balance approaches (at farm-gate, barn, and field scales) and further adapting these to the FARMFLOW model, we were able to combine mass flows and pools within the subsystems and establish links between subsystems in order to make farm-scale predictions. It was found that internal element flows on the farm are large and that there are farm internal sources (Zn) and loss terms (K). The approaches developed and tested at the Öjebyn farm are promising and considered generally adaptable to any farm. © Royal Swedish Academy of Sciences 2005.

    Application of broiler chicken manure to lettuce and cabbage crops.: Effect on yield, plant nutrient utilisation and mineral nitrogen in soil2002In: Acta Horticulturae, ISSN 0567-7572, Vol. 571, p. 119-126Article in journal (Refereed)
    Abstract [en]

    The use of broiler chicken manure is increasing in Sweden due to its reputation as a quick-acting nitrogen fertiliser. However, data concerning the effects on crops and the environment are limited. In 1998, a field trial was carried out at Ultuna with the aim of investigating the effects of spreading two different quantities of pelleted and stored broiler manure to iceberg lettuce and white cabbage. The parameters studied were yield, plant nutrient utilisation and amount of soil mineral nitrogen. Results from the field trial show that the pelleted broiler manure gave a better effect on yield than stored broiler manure. Nutrient balances showed that it is difficult to attain a good balance between application and uptake of nutrients when using broiler manure, especially pelleted. Soil samples indicate that the amount of mineral nitrogen in the soil after harvest did not differ significantly between the two broiler manures at the two levels of application. The results from this first year of field trials need to be confirmed with further trials.

    Risks and opportunities of increasing yields in organic farming. A review2018In: Agronomy for Sustainable Development, ISSN 1774-0746, E-ISSN 1773-0155, Vol. 38, no 2, article id 14Article in journal (Refereed)
    Abstract [en]

    Current organic agriculture performs well in several sustainability domains, like animal welfare, farm profitability and low pesticide use, but yields are commonly lower than in conventional farming. There is now a re-vitalized interest in increasing yields in organic agriculture to provide more organic food for a growing, more affluent population and reduce negative impacts per unit produced. However, past yield increases have been accompanied by several negative side-effects. Here, we review risks and opportunities related to a broad range of sustainability domains associated with increasing yields in organic agriculture in the Northern European context. We identify increased N input, weed, disease and pest control, improved livestock feeding, breeding for higher yields and reduced losses as the main measures for yield increases. We review the implications of their implementation for biodiversity, greenhouse gas emissions, nutrient losses, soil fertility, animal health and welfare, human nutrition and health and farm profitability. Our findings from this first-of-its-kind integrated analysis reveal which strategies for increasing yields are unlikely to produce negative side-effects and therefore should be a high priority, and which strategies need to be implemented with great attention to trade-offs. For example, increased N inputs in cropping carry many risks and few opportunities, whereas there are many risk-free opportunities for improved pest control through the management of ecosystem services. For most yield increasing strategies, both risks and opportunities arise, and the actual effect depends on management including active mitigation of side-effects. Our review shows that, to be a driving force for increased food system sustainability, organic agriculture may need to reconsider certain fundamental principles. Novel plant nutrient sources, including increased nutrient recycling in society, and in some cases mineral nitrogen fertilisers from renewable sources, and truly alternative animal production systems may need to be developed and accepted.

    Outdoor pig fattening at two Swedish organic farms-Spatial and temporal load of nutrients and potential environmental impact2007In: Agriculture, Ecosystems & Environment, ISSN 0167-8809, E-ISSN 1873-2305, Vol. 121, no 4, p. 407-418Article in journal (Refereed)
    Abstract [en]

    In Sweden, outdoor organic pig production is gaining interest. However, the excretory behaviour of pigs may create plant nutrient hotspots in outdoor areas, increasing the environmental impact. This study examined fluxes and balances of N, P, K, Cu and Zn at pen level, and determined the effects of the excretory behaviour of fattening pigs on nutrient load, manure distribution and N, P, K, Cu and Zn concentration in soil within pens at two farms with different outdoor systems (mobile and stationary). A pen in the mobile system had about 72 pigs ha-1 and in the stationary system about 91 pigs ha-1. The average pen balance in the mobile system was 270 kg N, 60 kg P, 110 kg K, 0.4 kg Cu and 1.3 kg Zn ha-1 and in the stationary system 205 kg N, 57 kg P, 99 kg K, 0.4 kg Cu and 1.5 kg Zn ha-1. The smaller net accumulation of nutrients in the stationary system was due to about 30% of excrement nutrients being excreted indoors. A substantial proportion of nutrients (43-95%) from one pig group was found to be concentrated in an area of arable land representing 4-24% of the total pen area. In the mobile system the major part of the defecating was deposited on the hut, feeding and drinking sub-areas. The manure mapping also revealed pig behaviour of avoiding defecation in certain zones. In the stationary system, the concentration of exchangeable P and K in soil (0-30 cm depth) in areas preferred for excretion was more than four-fold higher and the concentration of mineral-N (0-90 cm depth) was about eight-fold higher than in other areas of the pen by the end of the fattening period. Preferred areas for excretion within the pen were affected both by the present pig groups and by previous pig groups 4 years back in time. In the mobile system, the concentration of mineral-N in soil was about three-fold higher in preferred excretion areas compared with other areas. Neither of the two outdoor systems succeeded in avoiding excessive point loads of N within the pen. The flexibility of the mobile outdoor system has to be further improved so that no harmful point loads of nutrients can occur. In the stationary system, a nutrient management technique for collecting the manure on the preferred excretion areas on arable land needs to be developed. © 2006 Elsevier B.V. All rights reserved.

    Losses of N2O, CH4 and NH3 from a grass sward used for overwintering beef heifers2011In: Animal Feed Science and Technology, ISSN 0377-8401, E-ISSN 1873-2216, Vol. 166, p. 147-154Article in journal (Refereed)
    Abstract [en]

    This study evaluated losses of N2O, CH4 and NH3 from a rotational grazing system for overwintering beef cattle which spend 1 month on pasture. The cattle density was 71 heifers/ha and they were moved weekly to a new feeding area within the main pasture. The N2O, CH4 and NH3 losses were determined in two feeding areas that were severely trampled (ST) or less trampled (LT) and in a control area from which cattle were excluded. The N input to the pasture was measured. The NH3 losses were measured by micrometeorological mass balance in two periods with heifers present. The N2O and CH4 were measured using a closed chamber method with 9 chambers within each area on 10 occasions after heifers were removed from the pasture. The N input was 510kgN/ha. The NH4-N contents in the clay loam topsoil were 45, 28 and 11kg/ha in the ST, LT and control areas, respectively. Losses of NH3 were low due to rainy and cold conditions, corresponding to maximum 0.3kgN/ha/d. The soil was water logged and this, with the cold conditions, may have lowered N2O emissions. Maximum N2O losses were 7, 30 and 18gN2O-N/ha/d from ST, LT and control areas, respectively.

    Ammonia losses from outdoor pig fattening at two Swedish organic farms2012In: Open Agriculture Journal, ISSN 1874-3315, Vol. 6, no 1, p. 27-35Article in journal (Refereed)
    Abstract [en]

    Ammonia (NH 3) emissions originate predominantly from manure. In outdoor pig production, excretory behaviour creates nitrogen (N) point loads. This study examined ammonia losses from pigs on grassland at two farms by calculating N field balances per pen and sub-areas preferred (P) and not preferred (NP) for excretion. Spatial variation in ammonia losses was measured with an equilibrium concentration method in one pen per farm during two years at the end of the fattening period. Cumulative ammonia losses during a fattening period were measured using a micrometeorological mass balance method. P sub-areas had 10-to 100-fold higher amounts of excreted N than NP sub-areas. Ammonia losses were higher from P sub-areas (0.056-1.843 g NH 3 ha -1 hr -1) than from NP sub-areas (0.001-0.332 g NH 3 ha -1 hr -1). Ammonia losses from NP sub-areas varied more widely. Cumulative NH 3 losses were 28 kg pen -1. Gross NH 3 losses were 0.66 kg N pig -1, representing 14% of excreted N. © Salomon et al.

    Markstabiliserande material för att hindra trampskador på hårt belastade betesytor2017In: Vallkonferens 2017. Konferensrapport. 7–8 feb, Uppsala. Sveriges lantbruksuniversitet.

    Abstract [sv]

    En utvärdering av olika markstabiliserande material visade att den armerade mattan knappt påverkades alls av kotrafik under fyra betessäsonger och tre vintrar däremellan. Om mattan håller isju år blir den lika prisvärd som bark eller krossad sten. Barkbädden höll under rådande förhållanden inte mer än två år, men kan vara ett prisvärt material om man har egen tillgång på bark och lägger på ny bark då bädden uppvisar tendens att kollapsa. Det kan innebära att man får lägga på bark mer än en gång under varje betessäsong. Det krossade stenmaterialet hade efter två betessäsonger liknande antal gropar (framräknat med ett s.k. gropindex) som försöksleden med matta samt det där inga åtgärder vidtogs (kontrollen). Att inte göra någon åtgärd alls har fungerat vid rotationsbete där vegetationen haft möjlighet att återetablera sig. Samtidigt var det tydligt att en yta blev trampskadad då korna passerade den under en regnig period i augusti.

    Paths to a sustainable food sector: integrated design and LCA of future food supply chains: the case of pork production in Sweden2016In: The International Journal of Life Cycle Assessment, ISSN 0948-3349, E-ISSN 1614-7502, Vol. 21, no 5, p. 664-676Article in journal (Refereed)
    Abstract [en]

    Purpose: To describe a more sustainable food sector, a supply chain approach is needed. Changing a supply chain inevitably means that various attributes of the product and its system will change. This project assumed this challenge and delivered detailed descriptions, life cycle assessment (LCA) evaluations, and consequence assessments of the supply chains of six commodities, i.e., milk, cheese, beef, pork, chicken, and bread, from a Swedish region. This paper presents results for the pork supply chain. Methods: In the project setup, experts on production along supply chains designed three scenarios for environmentally improved systems. These scenarios, i.e., the ecosystem, plant nutrients, and climate scenarios, were intended to address different clusters of environmental goals. The next step was to challenge these scenarios by considering their possible consequences for products and systems from the food safety, sensory quality, animal welfare, consumer appreciation, and (for primary production only) cost perspectives. This led to changes in production system design to prevent negative consequences. The final supply chains were quantified using LCA and were again assessed from the three perspectives. Results and discussion: The scenario design approach worked well, thoroughly and credibly describing the production systems. Assessment of consequences bolstered the credibility and quality of the systems and results. The LCA of pig production and smoked ham identified large potentials for improvement by implementing available knowledge: global warming potential (GWP) could be reduced 21–54 % and marine eutrophication by 14–45 %. The main reason for these improvements was improved productivity (approaching the best producers’ current performance), though dedicated measures were also important, resulting in increased nitrogen efficiency, more varied crop rotations for crop production and better production management, and improved animal health and manure management for animal production. Reduced post-farm wastage contributed as did reduced emissions from fertilizer production. Conclusions: The working approach applied was successful in integrating LCA research with food system production expertise to deliver results relevant to supply chain decision-makers. The consequence assessments brought considerable value to the project, giving its results greater credibility. By introducing constraints in the form of “no negative consequences and no increased costs,” the work was “guided” so that the scenario design avoided being hampered by too many opportunities.

    A review of farm-scale nutrient budgets for organic farms as a tool for management of soil fertility2002In: Soil use and management, ISSN 0266-0032, E-ISSN 1475-2743, Vol. 18, no SUPPL., p. 264-273Article in journal (Refereed)
    Abstract [en]

    On organic farms, where the importation of materials to build/maintain soil fertility is restricted, it is important that a balance between inputs and outputs of nutrients is achieved to ensure both short-term productivity and long-term sustainability. This paper considers different approaches to nutrient budgeting on organic farms and evaluates the sources of bias in the measurements and/or estimates of the nutrient inputs and outputs. The paper collates 88 nutrient budgets compiled at the farm scale in nine temperate countries. All the nitrogen (N) budgets showed an N surplus (average 83.2 kg N ha-1 yr-1). The efficiency of N use, defined as outputs/inputs, was highest (0.9) and lowest (0.2) in arable and beef systems respectively. The phosphorus (P) and potassium (K) budgets showed both surpluses and deficits (average 3.6 kg P ha-1 yr-1, 14.2 kg K ha-1 yr-1) with horticultural systems showing large surpluses resulting from purchased manure. The estimation of N fixation and quantities of nutrients in purchased manures may introduce significant errors in nutrient budgets. Overall, the data illustrate the diversity of management systems in place on organic farms, and suggest that used together with soil analysis, nutrient budgets are a useful tool for improving the long-term sustainability of organic systems.

    An Assessment of the Variation of Manure Nitrogen Efficiency throughout Europe and an Appraisal of Means to Increase Manure-N Efficiency2013In: Advances in Agronomy, Vol. 119, p. 371-442Article in journal (Refereed)
    Abstract [en]

    Using the nitrogen (N) in organic manures more effectively reduces losses to the environment. A requirement to take allowance of the N conserved by reduced ammonia (NH3)-emission techniques would increase manure-N efficiency by up to 15%. Covering manure stores and land application of slurry by injection beneath the soil surface and by rapid incorporation of both slurries and solid manures into uncropped soil reduce NH3 emissions. Injection of cattle slurry also reduces N immobilization compared with application methods, which mix the slurry with soil and increases manure-N efficiency by ca 10-15%. In growing cereals, NH3 emissions can be reduced by band spreading within the canopy. Anaerobic digestion of slurry may also increase manure-N availability in the season of application by 10-20%, compared with undigested slurry. Slurry acidification may increase manure-N efficiency by 35-65% by reducing total NH3 losses by 70% compared with unacidified slurry stored without cover and not incorporated after spreading. To fully utilize the fertilizer value of manure-N, uptake over more than 1 year needs to be accounted for. This is particularly important for solid manures which provide less-available N in the season after application than slurries but release more N to crops in subsequent years. Using manure-N as a sole N source may limit overall manure-N efficiency. Applying manures at reduced rates over a larger crop area, using N fertilizer at times when crop recovery of manure-N may be limited, may give the greatest overall manure-N efficiency. © 2013 Elsevier Inc.
