Generally, soil biological activities are supposed to produce stable soil aggregates as well as variant sizes of pores which allows proper aeration and infiltration of water. With mechanical soil disturbance by tillage or cultivation practices, the biological soil structuring processes fade away. Minimum soil disturbances are responsible for maintaining the optimum composition of respiration gases, appropriate porosity for soil water movement, and germination of weed seeds. The minimum mechanical soil disturbances indicate permanent low soil disturbance, no tillage, and then involves no till direct seeding along with no till weeding.
