Target the crop not the soil - to reduce fertiliser use
Feed the crop not the soil’ is the message of a new review into sustainable phosphorus use. Currently, phosphorus fertiliser is applied to the soil, and plants then take it up through the roots. However, more precise nutrient management is needed on farms, the researchers say, so that the phosphorus is targeted at the crop just as it needs it. Modern agriculture is dependent on phosphorus, ...

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 ...

Tracking phosphorus runoff from livestock manure
Nutrient runoff from livestock manure is a common source of agricultural pollution. Looking for an uncommon solution, a team of scientists has developed an application of rare earth elements to control and track runoff phosphorus from soils receiving livestock manure. In addition to reducing the solubility of phosphorus, this method shows particular promise for researchers interested in tracking ...

New EPA requirements for controlling wastewater from large animal feeding operations
EPA has finalized a rule helping to protect the nation’s water quality by requiring concentrated animal feeding operations (CAFOs) to safely manage manure. EPA estimates CAFO regulations will prevent 56 million pounds of phosphorus, 110 million pounds of nitrogen, and 2 billion pounds of sediment from entering streams, lakes, and other waters annually. “EPA’s new regulation of animal feedlots ...
