- Abstract:
- ... Understanding how conservation agricultural management improves soil nitrogen (N) stability in the face of climate change can help increase agroecosystem productivity and mitigate runoff, leaching and downstream water quality issues. We conducted a 2-year field study in a 36-year-old rain-fed cotton production system to evaluate the impacts of changing climatic factors (temperature and precipitati ...

- Abstract:
- ... In cold humid temperate regions, peak nitrous oxide (N₂O) fluxes from agricultural soils occur during spring freeze-thaw periods. Fall-applied manure that adds water-soluble nutrients to the soil prior to freeze-up could contribute to spring N₂O emissions. The objective of our field experiment was to evaluate the relationship between water-soluble nutrients and N₂O emissions during the spring free ...

- Abstract:
- ... Soil nitrogen dynamics is affected by the interaction of cover crops and rainfall amount and distribution in rainfed agricultural production systems. There is a lack of understanding on soil nitrogen losses from cover crop-based based cropping systems receiving different rainfall amounts. A simulation model, RZWQM2 (Root Zone Water Quality Model), was calibrated and validated with field measuremen ...

A field experiment with separately tile‐drained plots was used to study the ability of oilseed radish (Rhaphanus sativus L.), as a cover crop sown after harvest of a main crop of cereals or peas, to reduce nitrogen (N) and phosphorus (P) leaching losses from a clay loam in southern Sweden over 6 years. In addition to oilseed radish in pure stand, two cover crop mixtures (hairy vetch (Vicia villosa ...

Inputs of this key nutrient contribute to increased yields, product quality and profits for farmers and ranchers across the globe. However, when higher rates of nitrogen (N) inputs than needed are applied to agricultural ...

- Abstract:
- ... Inefficient P use in agriculture results in soil P accumulation and losses to surrounding ecosystems, highlighting the need to use P inputs more efficiently. Composts reduce the need for mineral fertilizers by recycling P from wastes at the regional scale, whereas cover crops reduce soil P losses and have the potential to increase internal soil P recycling by mobilizing soil P “fixed” from previou ...

Surface broadcast of broiler litter to no-till row crops exposes the litter and its nutrients to risks of loss in runoff water and volatilization and may limit the potential benefit of litter to the crops. Subsurface banding of litter could alleviate these risks. A field study was conducted in 2008 and 2009 on an upland Falkner silt loam soil to determine the effect of broiler litter placement on ...

- Abstract:
- ... Managing manure in no-till systems is a water quality concern because surface application of manure can enrich runoff with dissolved phosphorus (P), and incorporation by tillage increases particulate P loss. This study compared runoff from well-drained and somewhat poorly drained soils under corn (Zea mays, L.) production that had been in no-till for more than 10 yr. Dairy cattle (Bos taurus L.) m ...
