Question 4

Q 4) Write a paragraph in your own words on each of the following.

(a) Preparation of soil (b) Sowing

(c) Weeding (d) Threshing

Solution 4

(a) Preparation of soil: The preparation of soil is the first step before growing a crop. One of the most important tasks in agriculture is to turn the soil and loosen it. This allows the roots to penetrate deep into the soil. The loosened soil helps in the growth of earthworms and microbes present in the soil.

(b) Sowing: Sowing is an important part of crop production. Before sowing, good quality, clean and healthy seeds of a good variety are selected. Farmers prefer to use seeds which give high yield. The process of putting seeds into the soil is called sowing. The tool used traditionally for sowing seeds is funnel-shaped. Nowadays a seed drill is used for sowing with the help of tractors. This tool sows the seeds uniformly at a proper distance and depth.

(c) Weeding: Some undesirable plants grow along with a crop. These unwanted plants are called weeds. The process of removing these unwanted plants is called weeding.

(d) Threshing: The process of separating grain seeds from the chaff is called threshing.
