What is fertilizer trace element?

Trace elements, also known as micronutrients, are essential nutrients required by plants in relatively small quantities for optimal growth and development. While primary macronutrients like nitrogen, phosphorus, and potassium are needed in larger amounts, trace elements are equally crucial for plant health, albeit in much smaller quantities. So last time in our article we have introduced about what is trace element and its application, if you are interested you can check out the link below. In this article tho, we are going to explained it more in detail how to apply the trace element fertilizer to the corps and its importance to the plant growth.

What fertilizer trace element is needed by the coprs?

• The fertilizers required by crops mainly include nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, organic fertilizer, trace element fertilizer, etc. The purpose of these fertilizers is to provide the following nutrients to crops: N, P, K, Ca, Mg, S, Fe, Mn, Cu , Zn, B, Mo, Cl. Crops absorb nutrients in the form of ionic elements.
• Among these elements, N, P, and K are large amounts of elements that are in large demand by crops, and it is relatively easy to supplement these elements to crops. Ca, Mg, and S are medium elements with medium crop demand.
• S generally does not require artificial supplementation because trace element fertilizers and soil contain a large amount of S.
• Mg is a component of crop chlorophyll and has a greater impact on crop photosynthesis, but it is easier for crops to absorb Mg.
• Ca has a great influence on the growth and development of fruits, and the ability of crops to absorb and utilize Ca is very low, so it is difficult to supplement Ca to crops.
• Fe, Mn, Cu, Zn, B, Mo and Cl are trace elements, which are required by crops in small amounts but have great effects. Among them, Cl does not need to be artificially supplemented.
• Crops have relatively high absorption and utilization capabilities for the four elements Mn, Cu, Zn, and Mo. Their demand for Fe and B is relatively high, and their absorption and utilization capabilities are also relatively poor.

1. The current Fe supplementation method generally uses chelated form, such as EDTA-Fe, but the price is higher;
2. B generally uses boric acid or borax.
3. Calcium fertilizer: Calcium is a medium element and a component of the gelatin layer of the cell wall. It has a certain impact on nitrogen metabolism in the body, participates in enzyme activities, regulates pH, and has a detoxifying effect on excess certain ions. Crops absorb calcium in ionic form and absorb more calcium
4. Calcium is not easy to move in the body, so calcium deficiency mainly occurs in root tips and terminal buds, causing plants to be short and premature.
5. Lime fertilizer is rich in calcium, which can neutralize soil acidity, eliminate poison, supplement soil calcium nutrition, promote the activity of beneficial microorganisms, improve soil physical properties, and reduce pests and diseases. Commonly used fertilizers are quicklime (burnt lime), mainly composed of calcium oxide; hydrated lime (slaked lime), mainly composed of calcium hydroxide;
6. Limestone powder, the main component is calcium carbonate. Calcium fertilizer is required for growing cotton, barley, wheat and alfalfa on acidic soil. Mainly base fertilizer, top dressing can be added. When applying lime, it is necessary to combine organic fertilizers, phosphorus, potassium, boron, and magnesium fertilizers; avoid mixing with ammonium nitrogen fertilizers and well-rotted organic fertilizers.
7. Sulfur fertilizer: Sulfur is a medium element, an indispensable component of proteins and enzymes, and affects chlorophyll and root nodule formation. The tops and young buds of sulfur-deficient plants suffer early, turning yellow first, with slender and unbranched roots and fewer fruits.
8. Gypsum (calcium sulfur fertilizer) and sulfur can improve alkaline soil, increase and improve crop nutritional conditions, such as increasing the dissolution of phosphorus and potassium salts. Leguminous crops like calcium, phosphorus and sulfur, so the effect is obvious. Superphosphate, ammonium sulfate, and potassium sulfate contain sulfur. Gypsum fertilizer is raw gypsum (ordinary gypsum). Its main component is calcium sulfate (CaSO4·2H2O), which contains sulfur 18 and CaO23 and is slightly soluble in water. Sulfur is elemental sulfur, with a content of 60-80% and long aftereffects. Brassicaceae, oilseeds (soybeans), vegetables and rice are sensitive to sulfur.
9. Magnesium fertilizer: Magnesium is a medium element. Magnesium is mainly found in chlorophyll. It is also a catalyst for many enzyme activities. It participates in fat and protein synthesis, is beneficial to the formation of vitamins A and C, and has a detoxifying effect on excess certain ions. Magnesium deficiency is mainly manifested in the lower old leaves. In mild cases, the leaves are chlorotic between the veins, and in severe cases, the leaves turn yellow, affecting yield.
10. Dolomite powder and magnesium carbonate are more effective in acidic soils, while magnesium oxide or magnesium sulfate is more effective in alkaline soils. Crops that are sensitive to magnesium include: leguminous crops, potatoes, flue-cured tobacco, oil crops, sugar cane, vegetables, rice, pineapples, bananas, oil palm, cotton, and corn. As base fertilizer and top dressing, apply lightly.
11. Boron fertilizer: The commonly used boron fertilizer is borax, which can be used as base fertilizer at a dosage of 0.3 to 1.0 kilograms per mu (667 square meters); for seed soaking, use an aqueous solution of 0.02 to 0.05; for foliar spraying, the concentration is 0.1 to 0.25.
12. Zinc fertilizer: Commonly used zinc fertilizers include zinc sulfate and zinc chloride. The dosage per mu (667 square meters) as base fertilizer is 0.5 to 2.5 kilograms; for seed dressing, 4 to 5 grams per kilogram of seeds is used; the seed soaking concentration is 0.02 to 0.05 aqueous solution; Spray an aqueous solution with a concentration of 0.05 to 0.2.
13. Molybdenum fertilizer: Ammonium molybdate is a commonly used molybdenum fertilizer. The amount of base fertilizer applied per mu (667 square meters) is 0.03 to 0.3 kilograms; when dressing, use 2 to 6 grams per kilogram of seeds; the seed soaking concentration is an aqueous solution of 0.01 to 0.05; it can Spray with an aqueous solution of 0.02 to 0.05 concentration.
14. Copper fertilizer: Commonly used copper fertilizer is copper sulfate, and the amount of base fertilizer applied per mu (667 square meters) is 1.5 to 2.0 kilograms; when dressing, use 0.6 to 1.2 grams per kilogram of seeds; an aqueous solution with a seed soaking concentration of 0.01 to 0.05; 0.02 to 0.02 grams can be used 0.04 aqueous solution spray.
15. Iron fertilizer: Commonly used iron fertilizer is ferrous sulfate. When used as base fertilizer, it should be mixed with organic fertilizer in a ratio of 1:20 before application; the spray concentration is an aqueous solution of 0.2 to 1.0, and the spray concentration of organic iron fulvic acid is Control it between 0.04 and 0.1.
16. Manganese fertilizer: Commonly used manganese fertilizers include manganese sulfate. The dosage of base fertilizer is 1 to 4 kilograms per mu (667 square meters); the dosage of seed dressing is 4 to 8 grams per kilogram of seeds. The concentration of seed soaking and spraying is 0.05 to 0.1. aqueous solution. commodity production or high-value cash crops. It is best to mix it with ammonium salt, potassium fertilizer and phosphate fertilizer.

How to apply trace element fertilizer to the plant? 5 ways in detail
