Molipden (Mo) – Molybdenum

Cultivated molybdenum plants are in the form of molybdate (MoO42-) and molybdenum oxide (MoO3) salts.                     1. Effect of Mo on the physiological biochemistry of plants.                        Mo plays an important role in many biochemical physiological processes in the plant: nutrient uptake (nitrogen fixation, nitrogen fixation and denitrification), respiration (oxidation – reduction) of photosynthesis (chlorophyll activation and […]

Manganese (Mn) – Manganese

The manganese cultivates manganese dioxide 2 Mn2+ and in the form of manganese organic complexes. Plants do not use four Mn4 + valence manganese. Mn forms in soil: – Mn2+ in solution – Mn2+ complex with organic matter – Mn oxides – Very low solubility: 10 -12 – 10 -15 M – pH dependent activity […]

Rare Earth Elements

1. The rare earth trace elements – Rare earth elements and rare earth metals, according to IUPAC (International Union of Pure and Applied Chemistry), is a collection of 17 chemical elements in the periodic table of Mendeleev called scandium, yltry and 15 (fifteen) elements of the lanthanum group and in contrast to the name (excluding […]

Calcium (Ca) – Calcium

The nutrient level of calcium is estimated as the percentage of Ca or CaO in the manure.                     1. The effect of calcium on soil and plants                     Calcium (Ca2+) accounts for most of the cell wall structure. Calcium mainly participates in the cell wall formation and the activity of many yeasts, which are important in maintaining […]

Magie (Mg) – Magnesium

Plants absorb magnesium in the form of useful Mg2+ Mg2+ cycle Origin: only in the soil Source of Mg2+ supplement: Soil minerals (dolomite, Mg sulfates …) Fertilizers & soil improvers New organic fertilizer Mg loss pathways: Wash drift (rough stone) Crop is absorbed (in the course of cultivation does not fertilize containing Mg) 1. Effects […]

Silic – Silicon

Useful species for crops: Silicon uptake in SiO32-ionic form, nutrient content calculated as% SiO2 1. Application of Silicon for Soil and Crop: – Plants including young plants also get silicon in the soil. When demand is low, the amount of SiO2 available in the soil may be sufficient to meet demand, but when demand is […]

Sulfur (S) – Sulfur

Plants absorb sulfur in the form of sulfur ion (SO42-) 1. Effects of sulfur on plants: * Sulfur in arable land: The amount of sulfur lost after each growing season ranges from 10 to 50 kg / ha. Except for some cereal crops, the amount of sulfur lost is usually equivalent to the amount of […]

Nitrogen (Nts) – Nitrogen

Introduction to protein nutrition (N) for plants Protein nutrition and nitrogen fixation in nature Protein Nutrition is the generic name for inorganic fertilizers that provide N (N) for plants – Nitrogen nutrients are evaluated as% Nitrogen – Most plants are not able to assimilate nitrogenous elements under the N2 form, but mainly in the form […]

Lân – Phosphate

Providing phosphorus to the plant as phosphate ion (PO43-) Fecundity of fertilizer is estimated as P2O5% in fertilizer. Phosphate is mainly DAP; FAT; TSP; NPK, phosphate, monophosphate, supephosphate, phosphate rich, phosphate. 1. Functions of Lan (P2O5hh) for plants Lan is the center of energy and protein metabolism Lan plays an important role in the formation […]

Kali – Potassium

1. The effect of potassium fertilizers on plants: Potassium is not really a constituent of plant tissue, but plants need to be fed a large amount of potassium to all parts. Potassium affects. Water control in the process of evaporation from plants. – When low light potassium stimulates photosynthesis, increase resistance to trees. – Potassium […]
