But it depends on suitable dose of nitrogen and on proper choice of catch crop for mulch. Grain yield of spring ba rley was lower in the conservation system. Conservation tillage influenced soybean grain production very favourably. This technology proved to have a very positive effect on grain yield of all crops on lisght sandy soil. The results of soil bulk densit y tests showed differences between both technologies at the end of vegetation period, but they were insignificant. Microbial activity tests documented positive, but insignificant changes of topsoil in the conservation tillage system." . . . .
