In order to ensure that these are readily available to the roots, the soil is ‘prepared’ before growing a crop. Soil preparation involves ploughing, leveling and applying fertilizers.
Ploughing: The process of loosening and turning the soil is called or ploughing or tilling. This process is important because of the following reasons:
Organisms like earthworms also in ‘Ploughing’ the field, as their burrowing action helps in loosening and turning the soil. These organisms also help in the decay of dead plants and animals in the soil. This process leads to the formation of a substance called humus, which is rich in nutrients for plants. Nowadays, implements called cultivators, which are driven by tractors, are increasingly being used for ploughing. This saves both time and effort. Tools used for ploughing are:
Leveling: Even after ploughing, big lumps of soil (called crumbs) may remain in the field. These are crushed using wooden or iron planks called levelers and this process is called leveling. After ploughing, the fuel is levelled with the help of leveller. It is because the ploughed soil is quite loose, so it is liable to be carried away by strong winds or washed away by rain water. The ploughed soil is levelled by pressing it with wooden leveller. Importance of levelling:
