Some Considerations for Using Compound Fertilizers (2)

Grasp the characteristics of compound fertilizer application (1) long compound fertilizer effect, suitable as base fertilizer. A large number of tests have shown that both binary and ternary compound fertilizers are based on basic application. This is because the compound fertilizer contains many nutrients such as nitrogen, phosphorus, and potassium. It is particularly sensitive to phosphorus and potassium in the early stage of the crop. Phosphorus and potassium fertilizers are required to be used as a base fertilizer. Controlled release compound fertilizer has adopted processes such as coating and granulation in the production process. The fertilizer effect is slow and steady. It is slower than the decomposition of simple chemical fertilizers. It has less nutrient leaching and high utilization rate. It is suitable for basal fertilizers. The average dosage per mu (667 square meters) is 30-40 kg. Compound fertilizer should not be used for seedling fertilizer and late-stage fertilizer to prevent greediness. The decomposition of compound fertilizer is slower. For crops that use compound fertilizer as the base fertilizer at the time of sowing, according to the law of fertilizer requirements for different crops, the available nitrogen fertilizer should be promptly added during top dressing so as to meet the nutritional needs of the crop. (2) There is a large difference in compound fertilizer concentration. Care should be taken to select the appropriate concentration. At present, most compound fertilizers are configured according to the average soil nutrient status of a region and the proportion of crops that need fertilizer. There are high-, medium-, and low-concentration series compound fertilizers on the market. Generally, low-level total nutrients are between 25% and 30%, medium concentrations are between 30% and 40%, and high concentrations are above 40%. It is necessary to use economical and efficient compound fertilizers because of different regions, soils and crops. Generally high-concentration compound fertilizers are used in economic crops, with high quality, low residue, and high utilization rate. The compound fertilizer has a high concentration and should avoid direct contact between the seed and the fertilizer. Compound fertilizer has high nutrient content. If it is in direct contact with the roots of seed or seedlings, it will affect sprouting and even burning seedlings and rot. When sowing seeds, the seeds should be 5 to 10 cm apart from the hole and the compound fertilizer. (3) Different ratios of compound fertilizers to raw materials should pay attention to the use of nutrient components. Different brands and different concentrations of compound fertilizers use different raw materials, and production should be selected according to the soil type and crop type. Nitrate-containing compound fertilizers should not be used in leafy vegetables and paddy fields; compound fertilizers containing ammonium ions should not be applied on saline-alkali soils; compound fertilizers containing potassium chloride or chloride ions should not be used on chlorine-tolerant crops or saline-alkali soils; Compound fertilizers containing potassium sulfate should not be used in paddy fields and acidic soils. Otherwise, it will reduce fertilizer efficiency and even poison crops. The compound fertilizer contains two or more kinds of macroelements. Nitrogen forms volatile loss or rainwater loss. Phosphorus and potassium are easily fixed by the soil. Phosphorus, especially phosphorus, is less mobile in the soil, and it is not easy to be absorbed and utilized by crop roots. It is also not conducive to the deep roots, in the case of drought, fertilizer can not be dissolved, fertilizer efficiency is worse, so the compound fertilizer should be deep-buried. The correct use of compound fertilizer will bring good benefits. In addition, when selecting compound fertilizer, it is also necessary to pay attention to the contained nutrient conditions, as well as packaging and manufacturers, and beware of being deceived.

Vitamins are organic compounds and vital nutrients that an organism requires in limited amounts. An organic chemical compound (or related set of compounds) is called a vitamin when the organism cannot synthesize the compound in sufficient quantities, and it must be obtained through the diet.


Your body needs them to work properly, so you grow and develop just like you should. They are essential for the normal growth and development of a multicellular organism. Once growth and development are completed, vitamins remain essential nutrients for the healthy maintenance of the cells, tissues, and organs that make up a multicellular organism; they also enable a multicellular life form to efficiently use chemical energy provided by food it eats, and to help process the proteins, carbohydrates, and fats required for respiration.
