Effect of Liquid Manure and Poultry Dung on the Humus Status and Productivity of Soddy-Podzolic Soil
The effect of liquid and semi-liquid fractions of poultry dung and pig and cattle manure applied together with straw on the humus status of soil and the productivity of cereals and grasses in crop rotation was studied in a field small-plot experiment. The liquid fractions of poultry dung and pig manure and semi-liquid cattle manure were found to be the most efficient.
