New trends in the planting methods reveal higher benefits for soil preservation
Direct planting, or “no tillage”, is a planting and fertilizing method involving the least possible movement of the soil at the moment of seed insertion, which is done through a small opening in the soil, which is then closed. In this way, the soil remains intact from planting until harvesting, leaving the residues from the previous harvest over the soil, which thus become organic fertilizers for the soil. This method not only allows preserving the soil structure, but also offers the following benefits:
• Prevent the erosion and wash of the soil generated by the rain and wind, that normally lead to the loss of valuable organic mass – mulch – which, in this way is being increased
• Less evaporation caused by the soil labour, with the consequence of saving water, allowing for early planting, higher productivity per ha., especially in places where the water is scarce
• Less nitrogen lixiviation...
