State the advantages of ploughing the soil. State the different ways through which it is done.
The advantages of ploughing the soil are:
- It improves air circulation, so that roots can respire easily.
- Roots can penetrate deeper into the soil; this enables them to hold the plant firmly.
- Ploughing enhances the water retaining capacity of the soil.
- Ploughing uproots the weeds growing in the field; it also aids in the growth of the microbes.
It is done by using a wooden or iron plough which is pulled either by oxen, or by a tractor.
