Fertilizers needed for intensive (that is, without increasing land area under cultivation) agriculture. Their application allows to increase the yield of any crops on already used areas. Of course, with the right approach. Fertilizers come in different types. Consider the differences between organic fertilizers from mineral.
The content of the article
Mineral fertilizers are called inorganic compounds that contain the substances needed by plants for normal growth. Depending on the availability of these substances, mineral fertilizers are divided into simple and complex. The complex includes several simple fertilizers in different proportions. A simple mineral fertilisers are divided into the following:
- Nitrogen, which, in turn, are divided into:
- urea (carbamide).
- Phosphorus; they are divided into:
- the precipitate;
- other phosphate fertilizers.
The production of mineral fertilizers are engaged in specialized enterprises of the chemical industry. Sometimes the chemical plants have one or more lines to produce different types of fertilizers.
Combined mineral fertilizers are compounds comprising both nitrogen and phosphorus. Often they have no single chemical formula (unlike, for example, ammonium nitrate) because they are a mixture of different substances. The difference between organic fertilizers from mineral in that the former is a product obtained from nature, while the latter produced artificially. Therefore, use of mineral substances have very wisely not to damage the fertility of the soil. Now let’s look into organic fertilizers.

Organic fertilizer is a product of animals. Also these include peat, sawdust, bark, and sediment basins (silt or sapropel). They have more value than mineral, as they are a natural element of ecological chain and can not harm the fertile layer of the soil. The most valuable organic fertilizer – manure and poultry manure is produced understandably in much smaller volumes than mineral fertilizers.
Although sawdust is the cheapest organic fertilizer, they can greatly increase the fertility of the soil. Often fertilizers are used rotten apples, in a good year on private lots is a lot. They just fall right into the earth, and ready to spring a good humus. But sawdust or vegetable waste (e.g. tops) is best done in the form of compost, that is, after having spent one or two seasons in a special pit, to weight perepela and digested by the plant.
