Improving the efficiency of using easily renewable resources in agriculture of the Kamchatka Territory

Abstract

The article is devoted to the study of the environmental impact of pre-pressed fish broth on soil fertility, which contributes to improving the quality of products and the renewal of resources in the Kamchatka Territory. Solving the problems of intensification of agriculture and increasing soil fertility mainly through the widespread use of pre-pressed broth and developing techniques that will reduce production costs and increase the efficiency of using easily renewable resources in agriculture of the Kamchatka Territory. Generally accepted methods of crop production, agriculture and agrochemistry were used in the research. In the experiment, a pre-pressed broth formed as a result of processing fish waste into flour was used. In the experiment, a pre-pressed broth formed as a result of processing fish waste into flour was used in order to increase soil fertility. The introduction of pre-pressed broth was carried out in autumn, winter, spring and summer. The study provides experimental data confirming the hypothesis that fractional use of pre-pressed fish broth throughout the year for fodder crops is one of the most rational methods of its disposal. The data on the effect of pre-pressed broth doses from fishmeal processing on the agrochemical properties of the soil (the content of available forms of nitrogen, exchangeable potassium, mobile forms of trace elements have been shown), yield and quality of oats (yield and chemical composition of the green mass of oats). The use of pre-pressed broth after the production of fishmeal as an organic fertilizer for composting peat with manure and application in its pure form can be considered promising.
