摘要: With the background of political concerns, land utilisation is confronted with serious need for protection soil fauna, landscape, climate and water quality more strongly now than ever before. In public discussions, agriculture increasingly exposed to reproach, destroying «natural fertility», because today’s sensitivity ecological damage. addition, intensity tillage looked at critically. Besides visible signs fertility loss, e.g. erosion by wind, sealing crusting surface, there are other problems, including deep compaction, reduced infiltration root penetration, organic matter content soil, high emission rates CO2 through fast biological oxidation fuel consumption as well drinking pollution leaching run-off nitrate, soluble phosphate xenobiotica that contribute overall environmental quality.
