NTP in agriculture in one of the areas represented chemicalization - widely used in all sectors of agriculture chemicals, tools and processes.
main areas of application of chemicals in agriculture are:
- manufacture of fertilizers and feed phosphates;
- enriching the soil with lime, gypsum and other substances in order to improve their structure;
- the use of plant protection products herbicides, rodenticide, insecticide;
- the use of growth promoters in plant;
- development of new methods of production of organic agricultural products;
- the use of growth promoters to increase animal productivity, the introduction of feed additives in the diet;
- agricultural use of polymeric materials;
- release materials that provide a means of mechanization in agriculture.
use of chemicals in agriculture is intended to ensure the growth of production, improve the quality and increase the shelf life of products, to ensure environmental requirements in agriculture and improve the efficiency of agriculture and animal husbandry.
chemistry and agriculture - are two inseparable concepts in our time.One of the major trends in agriculture is the production of fertilizers.Their efficiency is significantly increased in the combined use of other agricultural practices.
By origin all fertilizers are divided into mineral (inorganic), organic, bacterial and organic-mineral.
chemistry and agriculture are actively cooperating in the production and use of mineral fertilizers, which include inorganic materials obtained during the processing of inorganic material.On the composition of mineral fertilizers are divided into potash, phosphate, nitrogen and micronutrient fertilizers, which include molybdenum, boron, etc.
organic fertilizers, which offers chemicals and agriculture advantage of the needs of this peat, manure, food waste, bagasse, ornithopus, lupine and feces.These substances are nutrients of animal and vegetable origin.
In addition to these, there are organic and mineral fertilizers, containing in its composition of mineral and organic substances.Fertilizers of this type are obtained by treating organic substances with phosphoric acid or with ammonia, or by mixing organic fertilizers, such as peat, mineral fertilizers.
Modern chemistry and agriculture - is a productive use of bacterial fertilizers, which are drugs, which are part of the culture of microorganisms capable of fixing organic fertilizers and soil.These include Azotobacter and soil nitragin.
all fertilizers used in agriculture, classified by aggregate state into solid, liquid and Suspended and for agrochemical effects - direct, indirect or regulate plant growth.Direct
fertilizer designed to provide immediate power plant the various elements and trace elements, and simple to podrazdelyutsya (nitrogen - ammonium, ammonia, amide, nitrate, and combinations thereof; phosphate - soluble and insoluble in water but soluble in a solution of citric acid, andsparingly; potassium - raw salt and concentrated fertilizers, micronutrient - technical mixtures, which contain trace elements), and compound fertilizers.
Indirect fertilizers are used to improve the use of fertilizers and applied in the form of physical, chemical or microbiological effects on the soil.
