Assessment of Soils of the Vinnytsia Region for Organic Production Application

Abstract

The article reflects the results of a study of the development of organic technologies for agricultural production in the Vinnytsia region. A statistical generalization of the indicators of the development of organic technologies in the region was carried out and conclusions on the relevance of this strategic technological direction for the region were drawn. An assessment of the potential of Vinnytsia region for the introduction of technologies of organic farming and crop production in view of the national strategy of transition to alternative organic technologies are conducted. The peculiarities of the soil cover of the region from the standpoint of certain areas for the cultivation of organic products are analyzed. The results of cartographic assessment of the suitability of the soil cover of the region for the introduction of a staged transition to organic farming systems and the possibility of such a transition in different years of technology introduction are presented. The features of the soil cover of the region from the position of certain zones for the cultivation of organic products are analyzed. The basic regulatory criteria for assessing the suitability for classic organic production by the basic properties and groups of qualities defined by the orders of the Government of Ukraine are determined. The average agrochemical properties of soils in the Vinnytsia region in terms of humus content, mobile forms of nitrogen, phosphorus and potassium, and acidity of the soil solution are grouped and determined. The indicators of the content of mobile forms of trace elements, heavy metals and pesticide residues are separately grouped within the districts of the region. Based on a comparison of the normative values of soil parameters and the actual values of indicators within the regions, the integral coefficient of suitability of the soils of the region for the introduction of organic agricultural production technologies is determined. This made it possible to rank the districts of the region and identify favorable and unfavorable regions for the transition to organic technologies of agricultural production. Key words: organic technologies, suitability, standards, agrochemical assessment of soils, organic products.

Method for obtaining water retention properties of soils by fractions of their granulometric composition

“…As a result of the sand/clay gradation, which underlies Kachynskyi's classification, some soil types were obtained according to the granulometric composition (Tsytsiura et al, 2020): loose sand, cohesive sand, loamy sand, sandy loam, medium loam, clay loam, light clay, medium clay, heavy clay. It does not fully show the real diversity of soils in terms of granulometric composition.…”

Результати Агрохімічної Оцінки Темно-Сірих Опідзолених Оглеєних Ґрунтів Вінницького Природно-Сільськогосподарського Району (На Прикладі Дослідного Поля № 27 Прат «дашківці»)

“…Ґрунтовий покрив земель району представлений здебільшого типом сірих опідзолених лісових ґрунтів із їхніми підтипами -світло-сірими, сірими та темно-сірими. Ці ґрунти сформувались під широколистими дубово-грабовими лісами на карбонатних, лесових породах, в умовах досить теплого та не дуже вологого клімату [19]. Темні сірі ґрунти поширені на площі 14,9% від усіх ґрунтів Якушинецької громади.…”

“…Темні сірі ґрунти поширені на площі 14,9% від усіх ґрунтів Якушинецької громади. Ці ґрунти є найродючішими та придатними для вирощування всіх властивих цій зоні зернових і технічних культур [19].…”

Investigation of the ecological state of natural resources at agricultural enterprises of various forms of ownership in the eastern region of Opllia

“…Due to the fact that the soils generally have neutral reaction and the average humus content (within the limits of 2.0-3.5 % in all the plots), with the exception of certain fields at TzOV "Zhyva Zemlia Potutory", there are satisfactory conditions provided for obtaining high quality crop yields. As for nitrogen content, in order to ensure optimal conditions for growing grain and industrial crops, the soils should be provided with nitrogen content of more than 200 mg/kg of soil (Zeltner & Hirt, 2003;Kobets, 2004;Abasova, 2020;Tsytsiura, 2020).…”
