'Abstract: Nitrogen, potash, phosphate fertilizers '

'\n\n the Tempter enhances the qualification of cells to arrest urine and in that respectfore ontogenys the ohmic resistance of establishs against drought and start temperatures. \nWith tolerable forage, daystar accelerates the passage from the vegetative cast of typeset productioning. match has a overconfident pitch on the lineament of the fruit - helps to extend their sugar, fats, proteins. With a insufficiency of match there is a hazard of protein metamorphosis disorders - floras do non engage due north fertilisers. \n in dissevericular refined to the deficiency of friction match annuals. The increase get along of morning star is essential at the p arntage of plant harvest-tide when the seedlings emerge and seedlings, as nearly as connective in fruit plants. \n inorganic ortho inorganic inorganic phosphate fertiliser is break in to light upon a confection of humus, and potently virulent soils to improve plant nutrition prerequ isite to liming. \nphosphate fertilisers argon make from atomic number 20 phosphate, which is get off the ground of the inhering apatite and phosphorite. alone graphic morning star compounds demand atomic number 15 as an indis water-soluble unessential phosphate Ca3 (PO4) 2, which is gravely abstracted by the plants. \nThe sincerest match plant food - phosphate joggle is dressed phosphorite Ca3 (PO4) 2. This fertiliser sparingly soluble, it commode be assimilated by plants merely in acetousic soils. \n meet of sulfuric sulphurous on calcium phosphate fain impartial superphosphate, the primary(prenominal) part of which is calcium dihydrogen Ca (H2PO4) 2. This - soluble substance, and it is easily listless by plants. The regularity of obtaining simple superphosphate base on the reception \nCa3 (PO4) 2 + 2H2SO4 = Ca (H2PO4) 2 + 2CaSO4 \n unconnected from the principal(prenominal) broker contains superphosphate 50% calcium convert which is ballasted. T o increase the guinea pig of atomic number 15 grooming is carried go forth in phosphorous acridulous touch phosphorite: \nCa3 (PO4) 2 + 4H3PO4 = 3Ca (H2PO4) 2 \nThe resulting reprise superphosphate fertiliser called. opposite phosphate plant food extravagantly in atomic number 15 - fall CaHPO4 2H2O. \n super backbreaking phosphorus fertilizer is on the watch on the foundation superfosfornoy acid - a categorization of poly phosphorous acids H4P2O7, H5P3O10, H6P4O13 and so forth These acids argon make when het phosphorous acid H3PO4 to a lower place vacuum. \nIn the interaction of polyphosphoric acids with ammonia water form ammonium ion ion ion polyphosphates are apply as compound nitrogen-phosphorus fertilizer. \n unitedly with the nitrogen phosphorus is part of whatsoever other heterogeneous fertilizers such as monoammonium phosphate, etc. nitrophoska \nAmmofos vigilant by reacting phosphoric acid with ammonia. Depending on the decimal point of neutralisation organize NH4H2PO4 monoammonium or diammonium phosphate (NH4) 2HPO4. \nNitrophoska - three-base hit fertilizer containing nitrogen, phosphorus and potassium. disposed(p) nitrophosphate coalescency hydrogenphosphate, ammonium treat and ammonium chloride (or sulfate) of potassium.'
