Agrophysics quality assessment and soil moisture by application conservative system of soil tillage no-till from various agrocoenoses in Republic of Moldova

Abstract

Conservative agricultural system is a generic term utilized to define different modalities or agricultural management practices to land use in view sowing crops. The purpose of this paper is to agrophysics quality assessing and soil moisture by application of the conservative system of soil tillage No-till in Republic of Moldova. Conservation of soil tillage system offers more favorable conditions dense root system of plants (Aon et al., 2001; Barzegar et al., 2004) compared to hoes crops (maize). In this conservative system of work of carbonate chernozem (No-till) occurs water conservation under depth of 60 cm. According to planning for the year 2016 at the experimental resort Chetrosu were founded research polygons with conventional and conservative work of the soil - No-till within the stationary with crop rotation and permanent crop - maize. Crop rotation and research variants for the agricultural years 2014-2015 and 2015-2016 are presented in Table 1. Soil water reserves in the vegetation active phases of the autumn wheat were lower in compacted layers compared to the adjacent horizons (Boincean, 2013; Rusu et al., 2013). To moisture available to plants (17-20%) compared to 12-13% of withering coefficient, soil moisture and penetration resistance negatively correlated (r = 0.6-0.7).
