Conclusion •Mulch –and direct –seeding systems are fully developed and go well in practice. •The economical benefits must not ignore the nutrient – pesticide and soil movement (erosion). •Cereal – maize crop rotation needs a shallow mulch of crop residuals for a fast decomposition as a phytosanitary need (Fusarium Mycotoxines) •After harvest the growth of volunteer cereals has to be interrupted, they stand for a green bridge for plant diseases like barley yellow dwarf virus or Fusarium sp. and pests like aphids as a vector for the virus. •An immediately seeding of cover crops after harvest for a good development of the green manure. •Reduction of soil erosion is a requirement and possible •Reduction of CO 2 – emission is significant •Increase of microbial biomass •Increase of organic Carbon in the soil •A reduction of the costs is possible and necessary. •A prescription is not possible and depends from the crop rotation and natural situation.
“Es ist nicht die kräftigere Art die überlebt, auch nicht die intelligenteste, sondern die, die am schnellsten auf Änderungen reagiert” Charles Darwin It is not the strongest species which survives, also not the most intelligemt one, but that which reacts fastest to changes.
