Integrating animal and crop production can reduce nutrient leaching from agricultural fields
Nutrient leaching, the movement of plant nutrients from soil to water, can have negative effects on aquatic ecosystems due to eutrophication, which reduces the oxygen available in water, causing species and habitat loss. Ecological Recycling Agriculture (ERA), which is based on ecological principles and integrates crop production and animal husbandry, may limit this effect. This study ...

Improve crop yield by removing manure solids
Manure has long been used as a crop fertilizer, but the challenge of finding an efficient use of the nutrients found in manure is ever present. The ratio of nitrogen to phosphorus in manure is low in relation to the nutrient needs of most crops. Therefore, crops tend to be overloaded with manure to meet the nitrogen requirement of agricultural crops, but the excess phosphorus from the process can ...

Plant strategies for optimising nitrate intake
The less nitrogen there is in the soil, the better plants are at using it. Researchers from INRA, CNRS and CIRAD, in cooperation with Czech colleagues, have recently shed light on the crucial role of a protein that enables plants to not only assess their environment but also activate the proper adaptive response based on the conditions. This research, published in the 2 March 2015 issue of Nature ...

Straw residue helps keep nitrogen on the farm
Scientists are exploring ways to reduce non-point pollution from agriculture. A new study finds that using straw residue in conjunction with legume cover crops reduces leaching of nitrogen into waterways, but may lower economic return. Agriculture is the largest source of nitrogen non-point pollution to waterways in the United States, flowing into streams and rivers via erosion from farmlands, ...
