An important component in the agricultural technology tillage system with a view to creating favorable conditions for plant growth and development, leading to modification of the physical condition of the soil and taking direct action on chemical and biological soil characteristics, regardless of the cultivated plant. Maize is a crop less demanding of the previous plant. The best results are obtained by annual grain legumes and fodder followed autumn cereal grains, flax, hemp, potatoes, beets and sunflowers. Wheat maize rotation is required due to the weight of approx. 60% of the two cultures. In this rotation is favored maize is grown after a run-up early (www.agricultura-romania.ro). From research data is mentioned that both in cenosis maize monoculture (34 years) and maize in the crop rotation (after maize) following application of tillage - No-till soil moisture preserves layer is 40-50 cm, which and other researchers argue, regardless of the cultivated plant (Andriucă V., 2015). Conservation tillage system is best for rooting crops, including maize. CA is a precision agriculture with the purpose of preserving soil fertility.
