(introduction...)

Farmers have the habit of sowing in seed holes. The farmer makes a little hole with a stick or hoe, drops in several seeds and covers them with soil.

Some seed, such as rice, is sown broadcast; that is, it is thrown into the air, and falls all over the place.

Then a harrow is drawn to mix the seed with the soil.

Sowing

But the seed falls anywhere.

Sometimes the plants are too close together and get in each other's way when growing.

Sometimes the plants are not close enough. They do not make full use of the soil. With broadcast sowing it is not possible to get the right density (see Booklet No. 1, page 26).

When you want to get rid of weeds, you walk on the young plants and often spoil them.
