Intensification of bioproductivity of agricultural cultures by adding natural zeolites and brown coals into soils

AbstractOn the basis of relevant research works, the paper discuses positive effect of the utilization of non-traditional natural resources, the so-called agronomical ores, i.e. mineral fertilizers, in order to increase the productivity of crops and improve the physical and chemical properties of the soil. The effectiveness of such fertilizers is their complex positive influence on the properties and modes of the soil and, in general, on a system “soil-plant”. The paper shows the prospects of the use of zeolite-based substrates, brown coal and soil on the growth of test crops - barley. The conclusions reached in this study should be considered encouraging with regard to solving the problem in question
