Many soils are poor and do not yield a good harvest.

A modern farmer improves his soil.
· He gives it mineral salts (see Booklet No. 1, page 19);
· He improves its structure (see Booklet No. 4, page 24) by giving it humus.

Many soils are difficult to work.
· The soil is too dry or too wet.

The farmer improves the soil by irrigation and drainage.
· The land is full of trees.

The farmer grubs the trees.

Plants grow by taking mineral salts from the soil.
A plant that finds plenty of mineral salts in the soil grows quickly.
You must give the soil mineral salts. Manure, compost, fertilizers all add mineral salts to the soil.
