The use of nitrogen-containing industrial waste of animal origin as fertilizers

Currently, along with the intensive development of livestock production, there is a question of recycling waste generated as a result of its production. The aim of the study was to study the impact of industrial waste of animal origin on the quality and yield of spring wheat. The research was carried out in 2021-2022 in the conditions of the experimental field of I.A. Bunin YSU. The object of the study was the spring wheat variety Aquilon. It was found that the studied plant variants were distinguished by high rates of photosynthetic activity. The maximum values for chlorophyll a were characterized by plants in the variant where blood flour was used as fertilizer (20.68 mg/g of raw mass). Chlorophyll b was observed more in plants on variants using blood meal (18.05 mg/g) and corn meal (18.69 mg/g). The height of the plants in the variant using blood flour was the maximum, so in the phase of milk ripeness it was 70.6 cm. In the control variant , the height of plants in this phase of development was 58 cm. The highest protein values were recorded in the grain obtained in the variant where sheep wool was used as fertilizer - 16.5%, exceeding the control by 1.8%. Also, the grain obtained in this variant was characterized by high gluten levels - 31.3%. It should be noted that such indicators as gluten quality, vitreousness and the number of drops increased sharply compared to the control variant. The laboratory baking of bread from the obtained flour showed that the obtained samples of products according to organoleptic and physico-chemical parameters met the requirements of GOST.
