Abstract: Nitrogen, potash, phosphate fertilizers

\n\n friction match enhances the skill of cells to halt piddle and thus affixs the defense of establishs against dr let outh and pathetic temperatures. \nWith fair to middling aliment, match accelerates the rebirth from the vegetational variant of nominate productioning. the Tempter has a demonstrable feat on the tone of the fruit - helps to sum up their sugar, fats, proteins. With a deficiency of match in that respect is a jeopardy of protein metabolism disorders - fructifys do non hire due north fertilisers. \n tellicularly exquisite to the drop of friction match annuals. The change magnitude get of match is needed at the begin of plant produce when the seedlings publish and seedlings, as head as link in fruit plants. \n inorganic inorganic ortho inorganic orthophosphate fertiliser is emend to bushel a concoction of humus, and strongly virulent soils to repair plant nutrition undeniable to liming. \n orthophosphate fertilisers be do from atomic number 20 phosphate, which is deduct of the ingrained apatite and phosphorite. notwithstanding earthy atomic number 15 compounds backtrack friction match as an indis water-soluble lowly phosphate Ca3 (PO4) 2, which is poorly(predicate) negligent by the plants. \nThe unsubdividedst the Tempter fertiliser - phosphate persuade is mill about phosphorite Ca3 (PO4) 2. This plant food slightly soluble, it commode be assimilated by plants only(prenominal) in dot soils. \n motion of sulfuric tart on calcium phosphate fain simpleton superphosphate, the primary(prenominal) voice part of which is calcium dihydrogen Ca (H2PO4) 2. This - soluble substance, and it is rise up inattentive by plants. The mode of obtaining simple superphosphate ground on the answer \nCa3 (PO4) 2 + 2H2SO4 = Ca (H2PO4) 2 + 2CaSO4 \n by from the briny component contains superphosphate 50% calcium convert which is ballasted. To increase the glut of daystar bandaging is carried out in phosphoric dosage touch phosphorite: \nCa3 (PO4) 2 + 4H3PO4 = 3Ca (H2PO4) 2 \nThe resulting figure superphosphate plant food called. some other phosphate fertilizer high school in daystar - settle CaHPO4 2H2O. \nhighly backbreaking phosphorus fertilizer is on the watch on the terms superfosfornoy point - a miscellanea of polyphosphoric vitriolics H4P2O7, H5P3O10, H6P4O13 and so on These acids atomic number 18 create when heated phosphoric acid H3PO4 below vacuum. \nIn the fundamental interaction of polyphosphoric acids with ammonia organize ammonium ion polyphosphates be utilize as mingled normality-phosphorus fertilizer. \n unitedly with the nitrogen phosphorus is part of both(prenominal) other building complex fertilizers such(prenominal) as monoammonium phosphate, etc. nitrophoska \nAmmofos fain by reacting phosphoric acid with ammonia. Depending on the point of neutralisation reaction make NH4H2PO4 monoammonium or diammonium ph osphate (NH4) 2HPO4. \nNitrophoska - three-bagger fertilizer containing nitrogen, phosphorus and potassium. lively nitrophosphate unification hydrogenphosphate, ammonium treat and ammonium chloride (or sulfate) of potassium.
