AGROPHYSICS QUALITY ASSESSMENT AND SOIL MOISTURE BY APPLICATION CONSERVATIVE SYSTEM OF SOIL TILLAGE NO-TILL FROM VARIOUS AGROCOENOSES IN REPUBLIC OF MOLDOVA

摘要

Conservative agricultural system is a generic term utilized to define different modalities or agricultural managementpractices to land use in view sowing crops. The purpose of this paper is to agrophysics quality assessing and soilmoisture by application of the conservative system of soil tillage No-till in Republic of Moldova. Conservation of soiltillage 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 waterconservation under depth of 60 cm. According to planning for the year 2016 at the experimental resort Chetrosu werefounded research polygons with conventional and conservative work of the soil - No-till within the stationary with croprotation and permanent crop - maize. Crop rotation and research variants for the agricultural years 2014-2015 and2015-2016 are presented in Table 1. Soil water reserves in the vegetation active phases of the autumn wheat were lowerin compacted layers compared to the adjacent horizons (Boincean, 2013; Rusu et al., 2013). To moisture available toplants (17-20%) compared to 12-13% of withering coefficient, soil moisture and penetration resistance negativelycorrelated (r = 0.6-0.7).
