Organic fertilizers are used more effectively during their controlled application. The main factor determining the doze of fertilizers is the requirement of the plant in nutritive elements. The most important aim of the organic fertilizer application is the soil organic matter fulfillment and humus formation. It is established that humus loss amounts 1 ton per hectare annually on clay soils and 1,5 ton per hectare on sandy soils. Therefore annual dose of manure for humus renewal should compose 10-15 tons per hectare. A complex evaluation of the machines requirement for defecate manure utilization is made and analysis of manure removal system existing in the country is carried out. Classification of bedding-less manure (liquid manure, semi-liquid manure and sewage) depending on dry matter content is presented. Annual manure yield in different complexes with various removal systems is shown per swine and cattle farms. Annual yield of NPK is analyzed. Requirement of the machines for manure utilization is calculated.
