Magnesium Oxide Fertilizer - Magnesium Deficiency
Magnesium fertilizer generally refers to a fertilizer containing magnesium, which can provide magnesium to the soil after application. The more common fertilizers containing magnesium are magnesium sulfate, magnesium chloride, magnesium carbonate, magnesium nitrate, magnesium oxide, magnesium oxyphosphate, etc.
The effect of magnesium fertilizer on crops:
Magnesium is a component of plant chlorophyll and phytochemicals and is the only metal element in chlorophyll molecules. Magnesium plays an important role in photosynthesis. Magnesium ion is an activator of various enzymes, which promotes sugar conversion and metabolism in crops and promotes the synthesis of fats and proteins.
Magnesium has good migration in plants. When it is lacking, it will first appear in the old leaves. The typical symptoms are that the veins of the old leaves remain green and the veins appear yellowish or yellowish red. The yellowing is gradually expanding from the lower leaves and mature leaves. Leaves that are severely deficient will brown and die.
How does magnesium fertilizer increase the secretion of citric acid to protect the roots?
How does the root protect itself from metal elements? The secret components of crop roots contain carbohydrates, amino acids, organic acids and enzymes. These secret substances, in addition to being the food (bait) of microorganisms in the soil, It also helps a lot. For example, the use of citric acid in the roots of corn can alleviate the symptoms of blackening of the roots of aluminum. Magnesium fertilizer is applied and the roots secrete citric acid. Citric acid can promote the absorption of nutrients by crops
The nature of magnesium fertilizer
The constituents of chlorophyll. The crop is absorbed enough and the leaves become dark green and shiny.
2. It can activate various enzyme reactions in crops to promote metabolism and fertility improvement.
3. Easy to move between roots and leaves.
4. Easy to lose.
Magnesium fertilizer types and use options
Magnesium fertilizer
Magnesium sulfate (MgSO4): water soluble, neutral, immediate. Sulfur can enhance the disease resistance of crops. However, sulfur and magnesium tend to be excessive, and it is easy to produce hydrogen sulfide in water. Potassium magnesium sulfate fertilizer, which is a multi-element potassium fertilizer, in addition to potassium, sulfur, magnesium, also contains calcium, silicon, boron, iron, zinc and other elements, is weakly alkaline, especially suitable for acid soil application, generally used as base fertilizer It can also be used as a top dressing. Suitable for crops such as rice, corn, sugar cane, peanuts, tobacco, potatoes, beets, fruits, vegetables, and alfalfa. Compared with potassium (potassium chloride) and potassium sulphate, which are equivalent potassium (K2O), the application effect of potassium magnesium sulphate is better than that of potassium chloride, which is slightly better than potassium sulphate.
Magnesium hydroxide (Mg(OH)2): Although it contains a water-soluble part, it quickly saturates without being dissolved. In particular, larger granules are not easily dissolved. It is best to use it in base fertilizer, but it is less effective when used in top dressing. The soil pH can be neutralized when dissolved.
Magnesium carbonate (MgCO3): The water-soluble magnesium component is small, so it is phthalic acid-soluble magnesium. The alkaline ability of neutralizing acidic soils is not strong. Must be mixed with the soil.
