VII. Read the text without the dictionary, divide it for paragraphs and give the name to each paragraph. Application of fertilizers

Fertilizer must be put into the seedbed, where it will do most good to the young plant as it grows. This is done in two ways: a) fertilizer is spread on the seed-bed before the seed is sown and usually harrowed in; b) fertilizer is put in at the same time as the seed and usually near to it in the soil. Top-dressing means putting a fertilizer onto a growing crop. It is commonly done with nitrogen fertilizers on growing grain crops such as a spring dressing of sulphate of ammonia for a crop of winter wheat. If the nitrogen had been applied in the seedbed, most of it would be washed out during the win­ter. Lime and plant foods in fertilizers are not all used up in the year they are applied to the land. Some of the value is left over for a year or more and helps later crops.
