dvantages and Disadvantages
Producers must consider the advantage and disadvantages of a tillage system before changing systems. The most important advantage of conservation tillage systems is significantly less soil erosion due to wind and water. Other advantages include reduced fuel and labor requirements. However, increased reliance may be placed on herbicides with some conservation tillage systems. The herbicide labels do not change the recommended rates based on tillage system, but tillage may not be an option for weed control in some tillage systems.

Answer:
Ploughing is carried out in, it must not deteriorate the soil physical and biological condition. Its disadvantages stem from the loss of soil moisture and from the difficulties of the subsequent tillage operations. The most important advantage of ploughing is significantly less soil erosion due to wind and water.
