    При недостатке органических и минеральных удобрений, а также финансовых и технических средств особое значение приобретает рациональное использование севооборотов (правильного чередования культур во времени и пространстве) и учет природных особенностей агроландшафтов при проектировании систем земледелия. Работа посвящена анализу мониторинговой информации по урожайности культур зернотравяного севооборота в пределах мелиорированного агроландшафта. Вариантами опыта являются элювиальные, транзитные и аккумулятивные местоположения и их сочетания на вершине и склонах моренного холма.

    There is considered a problem of calculating the increase in water availability and productivity of agro-ecosystems through the use of mulching and reduced (minimum) soil tillage as well as predicting the mulching efficiency in various natural conditions. The model of heat-moisture exchange was used in the agro-ecosystems allowing the water balance dynamics in the root zone.

    The aim of the research is to carry out a comparative analysis of the effect of phosphohypso-containing fertilizer-reclamative compost (FRC) and iron-aluminium containing fertilizer-reclamative mixture (FRM) on the properties of ordinary alkali chernozem. The object of the study is ordinary chernozem degraded as a result of brackish water (1.7 g per dm3 on average in years) irrigation of sodium sulphate-composition. Soil samples were selected in the Rostov region in autumn before reclamation and annually after reclamation means usage in layers 0-20, 20-40 cm on permanent dynamic sites.
