Ammonium Phosphate Fertilizer
Ammonium phosphate fertilizer is a nitrogen and phosphorus compound fertilizer produced by the neutralization reaction of phosphoric acid and ammonia. This is one of the most productive and popular fertilizers, suitable for almost all soils and crops, with a high concentration of active ingredients, and not easy to absorb moisture and agglomerate. The production process of ammonium phosphate fertilizer is a combination of the production process of phosphate fertilizer and the ammonia processing process in the production of nitrogen fertilizer, which is economically reasonable.
Macroelement Water Soluble Fertilizer
A large number of elements water-soluble fertilizer is a kind of multi-component compound fertilizer that can be completely dissolved in water. It can be quickly dissolved in water and is more easily absorbed by crops, and its absorption and utilization rate are relatively high. In general, water-soluble fertilizers can contain all the nutrients required for crop growth, such as N, P, K, Ca, Mg, S, and trace elements. 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, and fertilizer but also saves labor. The benefits of using water-soluble fertilizers today are obvious.
Medium Element Fertilizer
Medium element fertilizers refer to a type of chemical fertilizers that contain one or more of the crop nutrient elements calcium, magnesium, and sulfur, and the content needs to be indicated. The minor constants are compared to the scale of production and application of the major constants nitrogen, phosphorus, and potassium. In addition to providing nutrients to crops, this type of fertilizer can also adjust the physical properties of the soil and increase agricultural production. Its soil conditioning functions are: ①Improve the effectiveness of phosphate fertilizers in the soil. In soils with high iron and aluminum oxides, the effectiveness of phosphate fertilizers is reduced due to the reaction of phosphates with iron and aluminum compounds. The application of calcium and magnesium conditioners to keep the soil pH at 6-7 can retard the above reactions. ②It is beneficial to the conversion of ammonium nitrogen in the soil into nitrate nitrogen, and most nitrifying bacteria need calcium. ③Promote the process of biological nitrogen fixation. ④Adjust the absorption of micronutrients by crops. When the soil pH is kept at 6~7, the micronutrients can maintain certain effectiveness for crops.
Biological Fertilizer
Bio-fertilizers are all based on organic matter and then mixed with inoculants and inorganic fertilizers. In a narrow sense, biological fertilizer refers to microbial (bacterial) fertilizer, referred to as bacterial fertilizer, also known as a microbial inoculant. It is made of microorganisms with special efficacy through fermentation (artificial cultivation) and contains a large number of beneficial microorganisms. After being applied to the soil, it can fix nitrogen in the air or can activate the nutrients in the soil and improve the nutrition of plants. The environment, or in the process of microbial life activities, produces active substances and stimulates specific microbial products for plant growth.In a broad sense, biological fertilizers generally refer to biological preparations produced by biotechnology and have specific fertilizer effects on crops. The active ingredients can be specific living organisms, metabolites of organisms, or transformation products of substrates. Microorganisms can also be animal and plant tissues and cells.
