Calcium fertilizers include calcium chloride, calcium nitrate, superphosphate, sugar alcohol calcium, amino acid calcium, etc.

1. Calcium chloride.

Calcium chloride is a calcium-containing fertilizer that can be soluble in water, which can be used as a calcium fertilizer for fruit trees, and can be used for bottom application, top application and foliar spraying. But at the same time, it can also provide chlorine, so avoid chlorine crops should be used with caution.

2. Calcium nitrate.

Calcium nitrate is a new type of high-efficiency chemical fertilizer containing nitrogen and available calcium, which has the characteristics of rapid calcium and nitrogen supplementation. It is widely used in agriculture for basal application, top application, flushing application and foliar spraying, and can also be used as a nutrient solution for soilless cultivation.

3. Superphosphate.

Superphosphate is a chemical acidic fertilizer, and the main component is monocalcium phosphate. It can be used as base fertilizer, top dressing, root top dressing and seed fertilizer, and is usually suitable for rice, wheat, corn, sorghum, cotton, melons, fruits, vegetables and other grains as wild materials and cash crops.

4. Calcium sugar alcohol.

Calcium sugar alcohol is a kind of sugar alcohol chelated calcium fertilizer that has been widely used in the market in recent years. On the basis of calcium fertilizer, sugar alcohol is a good complexing agent of medium and trace elements, which can form a stable complex with many nutrients, so that nutrients can be absorbed and utilized by plants faster.

5. Amino acid calcium.

Amino acid calcium is a kind of high-efficiency calcium fertilizer with amino acids as the carrier. It can promote photosynthesis and the formation of chlorophyll, and has a role in promoting and activating physiological and biochemical processes such as oxide activity, enzyme activity, seed germination, nutrient absorption, and root growth and development.

Now on the market, there are many common types of calcium fertilizer, as the name suggests, calcium fertilizer, is a fertilizer with calcium (ca) indicated amount, its important varieties are lime, including quicklime, hydrated lime and limestone powder, gypsum and most phosphate fertilizers, such as calcium magnesium phosphate fertilizer, superphosphate, etc. and some nitrogen fertilizers such as calcium nitrate, lime nitrogen, etc. also contain a considerable amount of calcium.

1. Raw stone ruined Karen ash: also known as burnt lime, the main component is calcium oxide, usually made of limestone, containing 90% 96% calcium oxide. If it is fired with dolomite, it is called magnesia lime, in addition to containing 55% 85% calcium oxide, there is also 10% 40% magnesium oxide, and has the effect of magnesium fertilizer.

Quicklime has a strong ability to neutralize soil acidity and can quickly correct soil acidity. In addition, it has insecticidal, weedicidal and disinfection effects.

2. Hydrated lime: also known as slaked lime, the main component is calcium hydroxide, which is made of quicklime hygroscopic or water-treated.

3. Carbonate lime: The main component is calcium carbonate, which is made of limestone, dolomite or shell fiber.

Calcium fertilizer mainly refers to lime, including quicklime, hydrated lime, lime powder, gypsum, carbonated lime, etc., in addition to calcium nitrate, calcium chloride, etc., calcium fertilizer is applied to plants, which can not only supplement calcium, but also regulate the acidity of the soil, eliminate the harm of aluminum, manganese and other ions in acidic soil to plants, and improve the fertilizer retention of the soil.

Calcium fertilizer mainly refers to lime, including quicklime, hydrated lime, lime powder, gypsum, carbonated lime, etc., in addition to calcium nitrate, calcium chloride, etc., this kind of calcium fertilizer can be dissolved in water, often used as root top dressing.

Applying calcium fertilizer to plants can not only supplement calcium, but also adjust the acidity of the soil, so as to eliminate the harm of aluminum and manganese plasma in acidic soil to plants, enhance the aeration and water permeability of the soil, and improve the fertilizer retention of the soil.

When the plant is deficient in calcium, the front end of the root will turn brown, the branches and leaves will be long, the texture will become soft, and the fruit powder is less, the fragrance is light, the new shoots are not ripe, the tree becomes weak, and in severe cases, it causes malnutrition and decreased immunity.

When applying calcium fertilizer, according to the growth needs of plants, before potting, the calcium fertilizer and the culture soil are fully stirred evenly, which can better promote the growth of the root system.

Lime, gypsum, and other calcium-containing fertilizers.

There are three types of agricultural gypsum: raw gypsum, cooked gypsum, and phosphogypsum. The solubility of calcium sulfate is very low, and the aqueous solution is neutral, which is a physiological acidic fertilizer. It is mainly used for alkaline soil, eliminating soil alkalinity, improving soil and providing crop calcium and sulfur nutrients.

1. Raw gypsum: that is, ordinary gypsum, commonly known as white gypsum, the main component is CaSO4·2H2O, and the calcium (Ca) content is about 23%. It is made of gypsum ore directly crushed, in powder form, slightly soluble in water, fine particles are conducive to dissolution, sulfur supply capacity and soil modification effect is also high, usually 60 mesh sieve hole is appropriate.

In addition to calcium, it also contains sulfur (S).

2. Plaster: also known as alabaster, its main component is CaSO4·1 2H2O, containing calcium (Ca). It is made by heating and dehydrating raw gypsum.

Strong hygroscopicity, after water absorption, it becomes raw gypsum, the physical properties become poor, the application is inconvenient, and it should be stored in a dry place. In addition to calcium, it also contains sulfur (S).

3. Phosphogypsum: the main component is CaSO4·2H2O, accounting for about 64%, of which it contains about calcium (Ca). Phosphogypsum is the residue after sulfuric acid decomposes phosphate rock to produce phosphoric acid, and is a by-product of the production of ammonium phosphate.

Its composition varies depending on the place of origin, and generally contains about 2% sulfur (S) phosphorus pentoxide.

The role and efficacy of calcium fertilizer are as follows:

1.Regulates the soil. For example, calcium fertilizer is helpful to loose soil, can neutralize soil pH, increase soil pH value, and improve the growth environment of soil microorganisms. In addition, calcium fertilizer can also increase the fertilizer retention capacity of the soil.

2.Supplement plant calcium. The use of foliar sprays can directly supplement the calcium of plants, and can also promote the absorption of nitrogen fertilizer by crops, if the lack of calcium, it will also affect the normal growth of plants, and will also affect the yield and quality, and then cause yield reduction.

3.Effective prevention of physiological diseases. In addition to promoting the absorption of other fertilizers and adjusting the acid-base balance of soil, calcium fertilizer can prevent physiological diseases of crops.

For example, the use of Aishi vine calcium fertilizer to supplement calcium, correct the symptoms of crop calcium deficiency and nutrient deficiency, effectively prevent fruit cracking, poor taste, bitter pox, umbilical rot and other physiological diseases caused by lack of calcium, and improve fruit quality.

At present, there are many brands of fruit tree calcium fertilizer on the market, and the best brands will vary depending on individual needs, geographical conditions and other aspects. Here are some suggestions for your reference:
