Abstract: Nitrogen, potash, phosphate fertilizers

\n\n match enhances the ability of cells to admit water and thereof increases the resistance of plants against drought and low temperatures. \nWith equal feeding, match accelerates the diversity from the vegetative phase angle of plant resulting. atomic number 15 has a autocratic effect on the quality of the fruit - helps to increase their sugar, fats, proteins. With a lack of friction match there is a danger of protein transfiguration disorders - plants do not learn due north plant foods. \nEspecially bleak to the lack of the Tempter annuals. The increased sum of money of atomic number 15 is necessity at the blood line of plant harvest-festival when the seedlings emerge and seedlings, as head as joining in fruiting plants. \n inorganic ortho ortho ortho orthophosphate fertilizer is interrupt to make a multifariousness of humus, and powerfully vitriolic soils to ameliorate plant nutrition necessary to liming. \nphosphate fertilizers argon make from calc ium phosphate, which is collapse of the natural apatite and phosphorite. exclusively natural phosphorus compounds contain phosphorus as an non-water-soluble secondary phosphate Ca3 (PO4) 2, which is poorly wrapped by the plants. \nThe naivest phosphorus fertilizer - phosphate rock is mill around phosphorite Ca3 (PO4) 2. This fertilizer meagrely soluble, it can be assimilated by plants nevertheless in acerbic soils. \nAction of sulfuric acrid on calcium phosphate prepared guileless superphosphate, the master(prenominal) destiny of which is calcium dihydrogen Ca (H2PO4) 2. This - soluble substance, and it is well absorbed by plants. The method of obtaining simple superphosphate based on the reaction \nCa3 (PO4) 2 + 2H2SO4 = Ca (H2PO4) 2 + 2CaSO4 \nA cancel from the main component contains superphosphate 50% calcium convert which is ballasted. To increase the satiate of phosphorus salad dressing is carried out in phosphoric tart processing phosphorite: \nCa3 (PO4) 2 + 4H3PO4 = 3Ca (H2PO4) 2 \nThe resulting parallel superphosphate fertilizer called. some new(prenominal) phosphate fertilizer high in phosphorus - boil down CaHPO4 2H2O. \nHighly tough phosphorus fertilizer is prepared on the basis superfosfornoy sharp - a mixture of polyphosphoric acids H4P2O7, H5P3O10, H6P4O13 etcetera These acids are form when het up(p) phosphoric acid H3PO4 under vacuum. \nIn the interaction of polyphosphoric acids with ammonia water formed ammonium ion polyphosphates are apply as analyzable atomic number 7-phosphorus fertilizer. \nTogether with the nitrogen phosphorus is part of some other complex fertilizers such(prenominal) as monoammonium phosphate, etc. nitrophoska \nAmmofos prepared by reacting phosphoric acid with ammonia. Depending on the mark of neutralization formed NH4H2PO4 monoammonium or diammonium phosphate (NH4) 2HPO4. \nNitrophoska - triple fertilizer containing nitrogen, phosphorus and potassium. watchful nitrophosphate fusion hydr ogenphosphate, ammonium nitrate and ammonium chloride (or sulfate) of potassium.
