2A plough or plow is a farm tool for loosening or turning the soil before sowing seed or planting. Ploughs were traditionally drawn by oxen and horses, but in modern farms are drawn by tractors. A plough may have a wooden, iron or steel frame, with a blade attached to cut and loosen the soil.
.The main advantages of soil ploughing are:
The loosening and turning of soil during ploughing bring nutrient-rich soil to top.
It improves air circulation so that roots can respire easily.
Ploughing improves the water retaining capacity of the soil.
It loosens the soil, such that the roots can penetrate deeper into the soil thus hold the plant tightly.
It helps in uprooting weeds.
It helps in the proper mixing of manure in the soil.
Organic matter decomposition is hastened to result in higher nutrient availability to the plants.
Ploughing helps in growth of microbes and worms (like earthworms) present in soil which are considered as farmer friends.
Since the capacity to absorb rainwater increases atmospheric nitrate mixed with water enters the soil and it increases soil fertility.
