Description:
Випуск журнала присвячено вивченню оптимізації технологічних прийомів вирощування сільськогосподарських культур. Особливу роль відведено впливу бобових культур на покращення родючості грунту, адаптивній селекції, інтродукції малопоширених декоративних видів, екології та охорони навколишнього середовища, зокрема, впливу хімізації на забруднення грунту та зернової продукції пестицидами, методам боротьби із шкодочинними об'єктами.

Annotation

The article presents the results of ecotoxicological assessment of grain production of agrocenosis according to the content of organochlorine pesticides. The aim of the research is the ecotoxicological assessment of the grain production of agrocenoses by the content of pesticide residues in the conditions of the forest-steppe right-bank. Field studies were conducted on the territory of agricultural enterprises of Shargorodsky, Peschansky and Kalinovsky districts of Vinnitsa region, located in the forest-steppe right-bank. Laboratory analyzes of soil, grain and seeds of field crops of agroecosystems were carried out in certified laboratories (Scientific-measuring agrochemical laboratory of Vinnitsa National Agrarian University and the laboratory of the testing center of Vinnitsa branch of the State Institution «Soil Protection Institute of Ukraine»). The studies determined the danger of contamination of grain products of agrocenosis with pesticides and their negative impact on the soil-plant system.

The research results showed that due to the resource-saving level of chemicalization when growing field crops, the average humus content in the soils of right-bank forest-steppe agroecosystems was 2.3.3.4 %, nitrogen, which is easily hydrolyzed . 63.0-77.0 mg/kg, mobile phosphorus . 120-180 mg/kg, exchange potassium . 68-94 mg/kg, while the hydrolytic acidity was 2.5-3.5 mg. equiv. / 100 g of soil and pH (salt) . 5.0-7.2. The agrochemical parameters of soils of agroecosystems, where intensive levels of chemicalization of agriculture are used, the elemental content, in particular in the available forms of nitrogen, phosphorus and potassium, was 1.4-1.6 times higher, but the hydrolytic acidity was almost halved and the soil pH increased. It was found that when growing winter wheat using resource-saving technologies, the pesticides load per 1 ha of agroecosystem is 3.53 l/ha, and for intensive technologies – 4.73 l/ha.

When growing spring barley, respectively, 3.53 l/ha and 4.03 l/ha, and corn - 0 and 0.85 l/ha. In general, the cultivation of winter wheat by intensive technologies causes an increase in pesticides load per 1 ha of agroecosystem by 25.4 % compared to resource-saving technology, the cultivation of spring barley by 12.4 %, and corn by 98.8 %.

It was established that in the forest ecosystems of the right-bank steppe at different levels of chemicalization of agriculture, the actual fluctuations in the agrochemical parameters of the soil depended on the field and predecessor crop rotation, and the content of organochlorine pesticide residues differed within the error and did not exceed their maximum permissible concentrations. The content of residual trace amounts of ã - HCH in the grain and seeds of the studied cultures was less than 0.02 mg/kg with a MPC of 0.5 mg/kg, DDT . less than 0.02 mg/kg with a MPC of 0.2 mg/kg.

Keywords: grain products, pesticides, organochlorine pesticides, agrocenosis, pollution.
