Object - processes change state humus chernozem podzolic under the influence of organic fertilizers. Purpose - determine the effect of organic fertilizers on transformation of state humus chernozem podzolic. Methods - the field, laboratory-analytical, comparative calculation, mathematical-statistical. Theoretical results - found transformation regularities of state humus chernozem podzolic under the influence of organic fertilizers based on qualitative and quantitative characteristics of organic matter and production conditions. Found that making compost from poultry manure increases of total and labile carbon; accumulation of humic acid and humic; improving the overall energy reserves of humus. Found that influence action and aftereffect compost positive effect on the formation of the molecular structure of humic acids. Practical results - the results of research can be used to develop measures to improve state humus of the soil in a shortage of organic fertilizers. Established a significant advantage use compost from poultry manure for humus formation. Based on research materials obtained utility model patent for "Method of bioactive fertilizer." Novelty - the peculiarities of formation of the physicochemical properties of humic acids under the influence and aftereffect of organic fertilizers based on poultry manure different qualitative and quantitative composition of organic matter by analyzing their electronic spectra; The influence action and aftereffect of organic fertilizer based on poultry manure on the formation of hydrophobic and hydrophilic properties of humic acids; The peculiarities of formation of the molecular structure and intermolecular bonds in humic acids under the influence and aftereffect of organic fertilizers based on poultry manure based on qualitative and quantitative characteristics of the organic component. Degree of application - materials of dissertation work is used in an educational process on preparation of master's degrees of Kharkiv National Agrarian University in teaching courses in the educational program «Expert evaluation of soil»; introduce on an area 50 hectare in the farm of Kharkiv region. The field is soil science.
