Effect of deep loosening of interrows on physical properties of sod-podzolic soil and yield of organic potato

The purpose of this research is to study the effect deep loosening row spacings on physical properties soil and yield organic potatoes. Two variants cultivation were used in spacings: usual 25 cm deep. was carried out with a row-crop chisel cultivator. Its design developed at institute. Analysis data obtained as result experimental studies showed that had positive compaction both inter-row width directly plough ridge. spacing during normal tillage average above 20 %, ridge by an 13 % compared tillage. assimilation moisture when using also trend, especially under condition large amount precipitation short period time. Thus, loss 34 mm, variant larger volume absorbed indicators increased sharply layers, 15 27 35 5 %. Potato 8.7 spacings. results should be recommendations carrying technological operations aimed caring for potato plantings.
