The series of papers in this issue AMBIO represent technical presentations made at the 7th International Phosphorus Workshop (IPW7), held September, 2013 Uppsala, Sweden. At that meeting, 150 delegates were involved round table discussions on major, predetermined themes facing management agricultural phosphorus (P) for optimum production goals with minimal water quality impairment. six (1) P a changing world; (2) transport pathways from soil to water; (3) monitoring, modeling, and...
This review summarizes current knowledge from the literature and experimental studies on role of cover crops (CCs) in reducing nitrogen (N) leaching phosphorus (P) losses to waters under marine humid continental climate conditions southern Scandinavia Finland. Field 11 sites indicate that undersown ryegrass (<i>Lolium</i> spp.) CCs are robust, with average N uptake aboveground CC biomass 7 38 kg ha<sup>−1</sup> (6.2 34 lb ac<sup>−1</sup>). Use sown at harvest (e.g., crucifers) is restricted...
Transport of phosphorus (P) from agricultural fields to water bodies deteriorates quality and causes eutrophication. To reduce P losses optimize use efficiency by crops, better knowledge is needed turnover in soil the best management practices (BMPs). In this review, we examined these issues using results 10 Swedish long-term fertility trials various studies on subsurface P. The are more than 50 years old consist two cropping systems with farmyard manure mineral fertilizer. One major finding...
Organic farming has been proposed as a means of reducing leaching and improving the use efficiency plant nutrients in agriculture. In such systems, nutrient inputs originate from various organic sources or naturally occurring minerals with low solubility. this study, measurements crop uptake N, P, K determinations mineral N soil were conducted tile‐drained plots during 6‐yr period two rotations, one without addition animal manures. latter, was provided by green For comparison, conventional...
Abstract This study investigated the effects of historical long‐term and recent single applications pig slurry on phosphorus (P) leaching from intact columns two sandy topsoils (Mellby Böslid). The soils had similar physical properties, but different soil P status (ammonium lactate‐extractable P; P‐AL) degree saturation (DPS‐AL). Mellby P‐AL 220–280 mg/kg DPS‐AL 32–42%, which was higher than for Böslid (P‐AL 140 DPS 21%). since 1983 four treatments with fertilizer histories, in summary high...
Abstract In this study, three types of cropping systems with different nutrient management strategies were studied on a clay soil the aim comparing leaching N, P and K obtaining knowledge budgets. A conventional system cereals application mineral fertilizers (CON) was compared two organic systems, one without animal manure in which green crops used for N supply (OGM) where (cattle slurry) applied (OAM). Leaching crop uptake K, measured pipe‐drained plots over 6‐year period. The mean annual...
A field experiment with separately tile-drained plots was established on a sandy loam soil in 1993 to investigate management practices that can reduce nutrient leaching. Practices tested included timing of tillage autumn or spring (ploughing without preceding cultivation) and catch crops systems mineral fertilizer alone combination pig manure. Drainage water from each plot collected analyzed for total nitrogen (tot-N), nitrate-N (NO3-N), phosphorus (tot-P), phosphate-P (PO4-P), potassium...
Appropriate management of animal waste is essential for guaranteeing good water quality. A laboratory leaching study with intact soil columns was performed to investigate the risk phosphorus (P) from a clay loam and loamy sand. The (0.2 m deep) were irrigated before after application pig slurry on surface or incorporation, mineral P, each at rate 30 kg P ha-1. two soils had different initial contents (i.e. ammonium lactate-extractable 65 142 mg kg-1 sand, respectively), but similar sorption...
Abstract The European Commission has set targets for a reduction in nutrient losses by at least 50% and fertiliser use 20% 2030 while ensuring no deterioration soil fertility. Within the mandate of Joint Programme EJP Soil ‘Towards climate‐smart sustainable management agricultural soils’, objective this study was to assess current fertilisation practices across Europe discuss potential harmonisation methodologies as strategy reduce loss overall use. A stocktake methods delivering advice took...
Abstract. Results are presented from three years (1992‐1995) of a field leaching experiment on sandy soil in south‐west Sweden. Plots spring cereals, either with or without an undersown perennial ryegrass catch crop, were compared for nitrogen and status soil. Both treatments ploughed spring, other tillage regimes also identical. Measurements drains, uptake crops mineral the made. Two coupled, simulation models, which describe water flow transformations transport soil, used to interpret data...
Abstract During 2005–2007, studies were carried out in two field experiments southwest Sweden with separately tile‐drained plots on a sandy soil (three replicates) and clay (two replicates). The overall aim was to determine the effects of different cropping systems catch crops losses N, P glyphosate. Different times glyphosate treatment undersown ryegrass examined combination tillage November or spring. Drainage water sampled continuously proportion flow analysed for Catch late autumn spring...
Cropping systems with high phosphorus (P) inputs may constitute a risk of P leaching, which contributes to eutrophication. The main objective this study was identify leaching risks associated three long-term fertilization regimes in separately tile-drained plots on sandy soil southwest Sweden. resulted different annual surpluses of, average, 16 kg ha−1 (14 lb ac−1) mineral form and 18 (16 37 (33 as pig slurry. importance characteristics (soil P, iron, aluminum, calcium content, degree...
Summary Two potential control methods for Elymus repens , which do not disturb the soil, are post‐harvest mowing and competition from under‐sown cover crops. Our aim was to quantify effect of crop on E. evaluate combining two methods. We present a two‐factorial split‐plot experiment conducted at three locations in Sweden, experimental rounds 2011–2012 2012–2013. A spring cereal with perennial ryegrass, red clover or mixture (subplots). Under‐sown crops were either mowed, mowed once twice...
