Economic efficiency of the use of broiler chicken wastes as organic fertiliser in the spring wheat production

This article analyzes the current state of broiler poultry in Ukraine. As a result of increasing the scale of production, the volumes of poultry waste increase proportionally. One of the promising areas increasing the sustainability of the domestic broiler poultry industry is the production of organic-mineral fertilizers, the use of which helps to preserve soil fertility and to increase the economic efficiency of this industry. To determine the efficiency of production of organic-mineral fertilizers based on chicken manure, their introduction into the cultivation of spring wheat was studied, using the following indicators: yield, production of additional products per unit area, grain costs, yield profit and the resulting level of profitability of the production chain. When investigating the dynamics of the profitability of poultry manure on the basis of statistical data, it was found that this indicator during 2016–2018 varied in the range of 5–7%. The increase in spring wheat yield (yield profit) was analyzed, as this indicator is the primary factor determining the level of profitability of the production chain. The efficiency of the use of chicken manure fertilizers in comparison with traditional organic fertilizers is confirmed by the increase of spring wheat yield by 12–24%. It was proved that the optimal dose of chicken manure fertilizers is a dose of 5–7 t/ha. Thus, in the cultivation of spring wheat, such fertilizers are a low-cost and resource-saving element. Given that the current state of Ukrainian agriculture is mainly determined by its poor economical state, the use of wastes of the broiler industry (manure and possibly also litter) is a promising way to make this industry sustainable and to enhance agricultural production with cheap and in principle environment-friendly fertilizers. It is concluded that the production of organo-mineral fertilizers from chicken manure as a by-product of animal origin is a relevant, economically feasible, effective and promising way in agriculture in the current socio-economic situation, because it allows to preserve and improve soil fertility and increase economic efficiency of poultry production.
