Supplementary nitrogen (N) side-dressing via the irrigation system is needed in organic cropping. The aim here was to improve N-extraction efficiency, by testing five extraction protocols with guano, layer and broiler manures. The manure-N released by the different methods and manures was mainly in the form of ammonia and ranged from 50% to 85% with no differences among extraction methods. Volatilised ammonia from the extract solution was trapped. At the end of the extraction period, the pH of… CONTINUE READING
