Terms of Sowing and Crop-Producing Power of SpringPlanted Cereal Crops on Overmoistened Mineral Soils in Poozerie

Abstract

Given: The results of many years’ research work on study of the influence of amelioration of overmoistened mineral soils onto the water regime of soil, the terms of sowing and crop-producing power of spring-planted cereal crops. It is stated that draining of soils accompanied by the procedures on organization of surface drain promote more rapid ripening of soil in spring and planting of barley and oat in average two weeks earlier during the years of research; extend the vegetation period for 6-8 days and nights; raise productivity of crops for 84.2 and 67.3%. The expenses for realization of reclamation works are compensated with increase of yield during 7-8 years.
