What are the commonly used trace element fertilizers? What are the characteristics

Previously, farmers used to use a lot of fertilizers when planting crops, but there were still problems with the growth of the crops and they didn't know how to solve them. With the rapid development of agricultural technology, people began to know that in addition to providing crops with commonly used large amounts of elements, they also needed to supplement some trace elements. What are the commonly used trace element fertilizers? What are the characteristics?

① Boron fertilizer. It is divided into boric acid and borax, both of which are white granules and can be bottled or simplified. Introduction to farming gang, generally used for spray and seed mixing. Boron can promote the movement of carbohydrates in plants. Boron deficiency in rapeseed can lead to "flower failure", while boron deficiency in wheat can lead to "ear senescence".

② Molybdenum fertilizer. There is also ammonium molybdate, which is also in the form of white sand. Usually packaged in brown bottles, it is often used for seed mixing, soaking, and later spraying. The physiological function of molybdenum in crops is mainly manifested in nitrogen metabolism, which is a component of nitrate reductase. Lack of molybdenum can lead to stunted and underdeveloped plants.

③ Zinc fertilizer. There is zinc sulfate in white granular form. It comes in both bottled and regular sizes. It can be used as a base fertilizer and sprayed later. Zinc is a component of many enzymes that can accelerate the hydration reaction of carbon dioxide. Zinc deficiency can cause the old leaves of fruit trees to turn green, resulting in thin and small leaves, leading to "small leaf disease" in fruit trees.

④ Copper fertilizer. There is copper sulfate, a blue-green crystal typically stored in brown bottles, mostly sprayed on fruit trees. Copper is a component of various enzymes in crops, which is beneficial for the formation of chlorophyll and promotes photosynthesis. The deficiency of copper is mainly manifested in the tender leaves, which makes them turn green.

⑤ Manganese fertilizer. There are manganese sulfate and manganese chloride, both white crystals, mixed with organic fertilizers for use as base fertilizers. Manganese is an activator of various enzymes, which can catalyze redox reactions, increase chlorophyll content, and promote carbohydrate movement. The leaves of manganese deficient crops become green and bright. Crops sensitive to manganese include wheat, potatoes, sugar beets, and legumes.

⑥ Iron fertilizer. There is also ferrous sulfate, which is often used on fruit trees and can be used as a base fertilizer. It's best to mix it well with organic fertilizer. It can also be diluted with water and sprayed. Iron is a component of various enzymes and nitrogen fixing enzymes in crops, which can affect crop respiration, photosynthesis, and nitrate reduction reactions. Iron deficiency in leguminous plants can weaken the nitrogen fixation ability of root nodules. Iron sensitive crops include sorghum, peanuts, soybeans, corn, and sugar beets, as well as vegetables and fruit trees.

What are the commonly used trace element fertilizers mentioned above? What are the characteristics of the relevant content. Farmer Help Supermarket stated that if there is a lack of trace elements during the planting process, crops will encounter various problems. Applying commonly used nitrogen, phosphorus, and potassium fertilizers will not improve much. If this situation occurs, it should be considered that plants lack trace elements.
