The effect of maize cultivation with undersown intercrops on soil fertility and reduction of soil erosion

Popis výsledku v původním jazyce

The technology with undersown crops allows maize cultivation on sloping fields, where maize cannot be grown without the use of soil conservation technology (mostly direct sowing in mulch from frozen cover crops). Sowing suitable crop species between the rows at the 3-4 leaf growth stage of maize creates the preconditions for covering the soil surface with vegetation cover, which has a sufficient protective function against erosion. The undersown crops showed to positively affect the soil structure and water content of the soil aggregates as well as the susceptibility of soil to water erosion. The improvement on soil biological properties (pH, soil respiration, selected enzymatic activities) and on the process of nutrient mineralisation has been also detected in our experiments. The greatest support for the functional diversity of the soil microbiome was achieved using undersowing of winter rye with crimson clover and Pannonian vetch. The experimental data shows that the anti-erosion effect of undersown crops increases with higher biomass production. From cereals, winter wheat and rye can be recommended, from clovers crimson clove, and from grasses especially ryegrass. A significant soil conservation effect was found for early sowing (about 2 weeks after sowing maize) of Italian ryegrass, which significantly reduced soil loss and surface runoff already in the first term (early June) of the rainfall simulation.
