Fertilizer market variety

Farmers are busy buying fertilizers, pesticides, seeds and other agricultural products during the farming season. At present, many new types of fertilizers are sold in the agricultural materials market. Farmers’ friends must first understand the functional characteristics of various fertilizers and then select and use them according to local soil characteristics and specific soil conditions:

New fertilizer

The special formula fertilizer can be applied as a top dressing as well as a top dressing according to crop growth requirements. Some areas have developed and released the main crop soil testing formula fertilization fertilizer formula can be used as wheat, corn, vegetables, fruit trees, potatoes, sweet potatoes, soybeans and other crop-specific formula fertilizer farmers can be based on their region and crop planting species and crop growth stages Choose the appropriate special formula fertilizer.

Commercial organic fertilizer

Generally used as a base fertilizer can also be used as top dressing. In terms of usage, the recommended amount varies according to soil fertility. For high-fertility new vegetable fields, the amount of refined organic fertilizer can be controlled at 300-500 kg/mu; in the fertile new vegetable field, 1 ton of refined organic fertilizer can be applied; low-fertilizer new vegetables Tian wants to strengthen the fertilization strength, and needs about 1-2 tons of refined organic fertilizer. When the organic fertilizer is used as the base fertilizer, it is better to apply a small amount of NPK compound fertilizer or phosphorus potassium fertilizer as the base fertilizer. The organic and inorganic compound fertilizer has higher nutrient content as the base fertilizer than the refined organic fertilizer; in the middle of the crop growth period, it can also be applied as top dressing according to the situation.

Water soluble fertilizer

Conventional water-soluble fertilizers contain all the nutrients required for crop growth such as NPK and various trace elements. When applied, the formula can be designed according to the nutrient demand characteristics required for crop growth to avoid unnecessary waste; because of the quick fertilizer effect, the fertilizer formula can be adjusted according to the crop growth at any time.

Trace element fertilizer

When applying micro-fertilizer, it should not be blindly applied or over-applied according to the lack of trace elements in the soil; it should be applied according to the pH of the soil; the application should be selected according to the response of crops to trace elements; Trace elements. Temperature and rainfall affect the release of trace elements in the soil and the absorption of crops by them.

Microbial fertilizer

When applying, qualified products should be used to minimize the death of microorganisms. Create a suitable soil environment. Choose different types to avoid mixing with unfertilized farmyard manure under high temperature and drought conditions. At present, the facility protection sites of the South Fruit North species need to use such fertilizers to regulate soil pH.

Slow release fertilizer

The so-called slow-release fertilizer refers to the fertilizer that has its initial release of nutrients through various regulation mechanisms to extend the effective period of its effective nutrient absorption and utilization, so that its nutrients are slowly or controlled to release according to the set release rate and release period. The fertilizer has the advantages of improving fertilizer utilization rate, reducing the amount of use and fertilization, reducing production cost, reducing environmental pollution, improving the quality of crop products, etc. The outstanding feature is that the release rate and release period are combined with the crop growth law to make the fertilizer nutrient effective. The utilization rate is increased by more than 30%. Slow-release fertilizer is a special film on the outer layer of traditional fertilizer. According to the nutrient demand of crops, the release rate and release of nutrients are consistent with the crop demand. The outstanding feature of the fertilizer is that the effective nutrient is fed synchronously according to the curve of crop growth, so that the effective utilization rate of fertilizer nutrient can be greatly improved. Under the premise of ensuring crop growth, the fertilizer efficiency can be increased by more than 30% compared with the same concentration of fertilizer. The amount of use is greatly reduced. Slow and controlled release fertilizer is mostly used for the application of the base fertilizer to meet the nutritional requirements of the crop throughout the growing season.

Soil conditioner

The soil conditioner is made up of agricultural water-retaining agent and natural peat rich in organic matter, humic acid or other organic materials, supplemented by bioactive components and nutrients. The products processed by scientific process have extremely remarkable water retention and increase. Fertilizer, breathable, three soil conditioning properties. It can break soil compaction, loose soil, improve soil permeability, reduce soil bulk density, promote soil microbial activity, and enhance soil fertility and water penetration; improve soil, control desert water retention and drought resistance, enhance crop disease resistance, increase crop yield, and improve agricultural product quality The functions of restoring the original ecology of crops and other functions have greatly improved the survival rate of tree planting and the output of agricultural products; improving the quality of agricultural and forestry products and restoring the natural features of agricultural and forestry products. It is completely pollution-free, pollution-free and free of biological hormones. Different from various fertilizers, pesticides, foliar fertilizers and biological hormones on the international market, it is a new type of green production data for agroforestry cultivation in the world.

Humic acid soil conditioners improve soil physical, chemical and microbial responses to increase soil fertility. The main constituent of humic acid in peat is that humic acid and fulvic acid have been shown to promote root development and beneficial microbial activity. Simply put, humic acid soil conditioner can help the soil release various nutrients that are beneficial to plant absorption. Soil compaction, desertification, salinization, soil permeability increase, soil water retention and fertility reduction, soil moisture evaporation, soil increase The cation exchange capacity promotes the better absorption of trace elements by plant roots, which facilitates the chelation of plants with iron, magnesium, zinc and copper, and the absorption of salt to absorb Na+ in soil.
