The difference between water soluble calcium and calcium oxide used in crops

The difference. Water-soluble calcium is soluble in water and easily absorbed by plants, while calcium oxide is insoluble in water.

Water soluble fertilizer (WSF) is a multi-compound fertilizer that can be completely dissolved in water.

It can be quickly dissolved in water, more easily absorbed by crops, and its absorption utilization rate is relatively high, and more importantly, it can be applied to facility agriculture such as sprinkler and drip irrigation.

Realize the integration of water and fertilizer to achieve the efficiency of saving water, fertilizer and labor. with traditional superphosphate.

Compared with granulation compound fertilizer and other varieties, water-soluble fertilizer has obvious advantages. Its main characteristics are low dosage, easy to use, low cost, fast absorption of crops, and extremely high utilization rate of nutrients. In this way, people can design the formula according to the characteristics of the nutrient requirements required for crop growth, and the scientific formula will not cause the waste of fertilizer, so that its fertilizer utilization rate is almost the same as that of conventional compound chemical fertilizer.

(In China, the fertilizer utilization rate of ordinary compound fertilizer is only 30%-40%).

Secondly, water-soluble fertilizer is a fast-acting fertilizer, which allows growers to see the effect and performance of fertilizer quickly, and can adjust the fertilizer formula at any time according to the different growth of crops. Of course, the application method of water-soluble fertilizer is very simple, it can be fertilized with irrigation water including sprinkler irrigation, drip irrigation, etc., which not only saves water, but also saves fertilizer, and also saves labor, which is the benefit of using water-soluble fertilizer in today's increasingly high labor cost is obvious. Since the application method of water-soluble fertilizer is irrigated with water, the fertilizer is applied very evenly, which also lays a solid foundation for improving yield and quality.

Water-soluble fertilizers generally have fewer impurities and conductivity.

It is low and the concentration is very easy to adjust, so it is safe even for young seedlings, and there is no need to worry about adverse consequences such as seedling burning.

Water-soluble calcium is more easily absorbed by crops, and calcium oxide is insoluble.

The uses of calcium hydroxide in agriculture include: in agriculture, calcium hydroxide can effectively reduce the acidity of the soil and improve the soil structure; Bordeaux liquid pesticides can also be made from aqueous solution of lime milk and copper sulfate to kill insects. In addition, the lime slurry in calcium hydroxide solution can also be applied to the roots of trees about 80 cm above the roots to help trees survive the winter and prevent insects.

Calcium hydroxide is an inorganic compound with the chemical formula Ca(OH)2, commonly known as hydrated lime or slaked lime. It is a white powdery solid, after adding water, it is two layers, the upper layer of aqueous solution is called clarified lime water, and the lower layer of suspension is called lime milk or lime slurry. The upper layer of liquid clarified lime water can be used to test carbon dioxide, and the lower layer of turbid liquid lime milk is a building material.

Calcium hydroxide is a strong alkali, which has the ability to kill bacteria and antiseptic, and has a corrosive effect on ** and fabrics. Calcium hydroxide has a wide range of applications in industry. It is commonly used as a building material, and is also used as a fungicide and chemical raw material, etc.

Calcium hydroxide is a fine white powder at room temperature, slightly soluble in water, its clear aqueous solution is commonly known as excitation clear lime water, and the emulsion suspension composed of water is called lime milk. Stalking and solubility decreases with increasing temperature. Insoluble in alcohol Kai lead socks, soluble in ammonium salts, glycerol, can react with acids, to generate the corresponding calcium salt.

At 580, it decomposes into calcium oxide and water. Calcium hydroxide is a strong alkali and has a corrosive effect on ** and fabrics. However, because its solubility is not large, the degree of harm is not as great as that of strong alkalis such as sodium hydroxide.

Introduction to calcium hydroxideCalcium hydroxide, also known as hydrated lime, slaked lime, etc., is a white powdery solid. Calcium hydroxide is mixed with water, and then precipitated to form clarified lime water and lime milk, of which lime milk is also called lime slurry, and clarified lime water can be used to test carbon dioxide.

Uses of calcium hydroxide in agricultureThere are many uses of calcium hydroxide, in the macro liquid of the Agricultural Bureau, calcium hydroxide can effectively reduce the acidity of the soil, as well as improve the soil structure; Bordeaux liquid pesticides can also be made from aqueous solution of lime milk and copper sulfate to kill insects. In addition, the lime slurry in the calcium hydroxide solution can also be applied to the root of the tree about 80 cm above the root part of the tree to help the tree to prevent insects in winter.

1. In agriculture, calcium hydroxide can effectively reduce the acidity of the soil and improve the soil structure; Bordeaux liquid pesticides can also be made from aqueous solution of lime milk and copper sulfate to kill insects.

2. In addition, the lime slurry in the calcium hydroxide solution can also be dismantled and applied to about 80 cm above the roots of the tree to help the tree edge imitation wood for winter insect control. Travel base line.

1) Most substances can be dissolved in water to form early plum solution, as long as there is water in the solution culture, water must be a solvent, so the most commonly used solvent is water;

2) Compound fertilizer is a fertilizer that contains nutrients in the chemical formula: two or three of the three elements of N, P and K, and nitric acid with orange potassium contains nitrogen and potassium, so it belongs to compound fertilizer;

3) Oxygen can supply breathing, often used in diving, medical rescue So the answer is: (1) ; 2）⑤；3）③．
