Crop yield improved by removing manure solids

Manure has long been used as a crop fertiliser, 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 damage the environment.

In a study funded by agriculture and Agri-Food Canada, scientists at the Pacific Agri-Food Research Center in Agassiz, British Colombia, with collaborators in Quebec City, Quebec, and Brandon, Manitoba tested the effectiveness of removing solids from dairy manure to improve yield by increasing the nitrogen to phosphorus ratio and reducing the loss of nitrogen by hastening soil infiltration.
