Fertilizers - inorganic compounds that contain the necessary elements for plant nutrition.

Fertilizers contain nutrients in the form of various mineral salts. Depending on what nutrients are contained in them, fertilizers are divided into simple and complex. Simple (unilateral) fertilizer containing any one element of power. These include phosphorus, nitrogen, potassium and microfertilizers. Complex, or multilateral, fertilizers containing two or more major nutrients.

In soils usually have all the necessary plant nutrients. But often the individual elements are not enough for the satisfactory growth of plants. On sandy soils plants often lack magnesium, on peat soils - molybdenum on black - manganese, etc. The application of mineral fertilizer - one of the basic techniques of intensive farming. With the help of fertilizers can dramatically increase the yields of all crops in already developed areas at no additional cost to process new land.

To make chemical fertilizers are used fat seeders.
