AGGREGATE STRUCTURE OF AGRO-GRAY SOILS OF VLADIMIR OPOLYE: COMPOSITION AND STRENGTH OF AGGREGATES

A complex of soils characteristic of the Vladimir Opole region was studied: agro-gray typical Guitar Processor deep-arable soil, tongue-shaped agrozem and agro-gray gleyic soil.The high contrast of soil properties, which is due to the genesis of field landscapes, can be traced in the differences in the arable and subarable horizons of agro-gray soi

The unstable flow of a shaft tubular pump device (STPD) leads to energy loss, thereby reducing its efficiency.The aim of this study is to investigate the distribution pattern of energy loss in STPDs.This paper reveals that the two components with the highest proportion of energy loss are the impeller and the outlet passage.Furthermore, turbulent en
