Farmers all know that a single flower in a crop depends entirely on fertilizer, and fertilizer plays a decisive role in determining crop yield.

The yield of vegetables is related to fertilizers, the quality of vegetables is related to fertilizers, the number of vegetable diseases is related to fertilizers, and premature aging, death, flower and fruit drop, and dry leaves are closely related to fertilizers.

There are many types of fertilizers, including nitrogen, phosphorus, potassium fertilizers, trace element fertilizers, and bio fertilizers. Each type also has many categories, and the efficacy of each fertilizer is also different. Everyone may know that nitrogen leads to leaves, phosphorus leads to fruits, but for fertilizers containing trace elements and biological fertilizers, what can they grow if applied too much?

Massive elemental fertilizer

Major element fertilizers mainly refer to nitrogen, phosphorus, and potassium fertilizers.

Nitrogen: It mainly supplies leaf growth, converts various nutrients through chlorophyll to meet crop growth, and promotes the robust growth of branches, straw, and stems.

Phosphorus: determines flower bud differentiation, pollen tube elongation, and determines the number and yield of fruits produced.

Potassium: When applied in moderation, it can make crop stems grow strong, prevent lodging, promote flowering and fruiting, enhance drought resistance, cold resistance, and resistance to pests and diseases.

Medium Element Fertilizer

Medium element fertilizers mainly refer to calcium, magnesium, sulfur, and silicon fertilizers.

Calcium: Applying lime to calcium deficient soils can not only provide plants and soil with calcium supplementation, but also increase soil pH, thereby reducing or eliminating the harmful effects of large amounts of iron, aluminum, and manganese ions in acidic soils on soil properties and plant physiology.

Magnesium: Magnesium is one of the main components that make up chlorophyll in plants and is related to photosynthesis.

Sulfur: Sulfur is an important component of sulfur-containing proteins in plants, and it can also promote the formation of root nodules and increase nitrogen fixation capacity in leguminous plants.

Silicon: Silicon fertilizer is beneficial for improving crop photosynthesis and chlorophyll content, making stems and leaves straight, resisting lodging, and promoting organic matter accumulation; In addition, it can also provide crops with the ability to resist diseases and pests.

Trace element fertilizer

Trace element fertilizers mainly refer to nine types of fertilizers, including iron, manganese, molybdenum, copper, boron, zinc, chlorine, sodium, cobalt, etc.

Iron: is a component of some important oxidoreductases in plants; Iron is not a component of chlorophyll, but it is essential for the formation of chloroplast structure.

Manganese: Manganese controls many redox reactions in plants, acts as an activator of many enzymes, and directly participates in the photolysis of water in photosynthesis. Manganese is also a structural component of chloroplasts.

Molybdenum: Molybdenum is a component of nitrate reductase and participates in the reduction of nitrate and nitrogen metabolism in plants. It is also the main component of nitrogenase, so leguminous plants have a good response to molybdenum fertilizer.

Copper: It is related to redox reactions and respiration in plants, and has a significant impact on protein metabolism and chlorophyll formation. It enhances photosynthesis, promotes pollen germination and pollen tube elongation, and increases seed setting rate.

Boron: Boron can promote root growth, play an important role in the synthesis and transport of carbohydrates, a product of photosynthesis, and have a special effect on the normal process of fertilization.

Zinc: Zinc indirectly affects the synthesis of auxin in crops; Zinc is also an activator of many enzymes, which has a wide range of effects on plant carbon and nitrogen metabolism, thus contributing to photosynthesis; Zinc can also enhance plant stress resistance, increase grain weight, and change the ratio of seeds to stems.

Chlorine: The application of chlorine fertilizer should be cautious, but chlorine can participate in photosynthesis, promote crop growth, and regulate plant cell osmotic pressure; In addition, it can activate the action of enzymes in crops and promote the growth of crop roots.

Sodium: After contact with plants, it can quickly penetrate into the plant body, promote the flow of cell cytoplasm, increase cell vitality, promote growth and development, prevent flower and fruit drop, improve product quality, and increase yield; Improve the stress resistance of crops, including disease resistance, insect resistance, drought resistance, flood resistance, cold resistance, salt alkali resistance, and lodging resistance.

Cobalt: Cobalt is an essential element for nitrogenase in symbiotic nitrogen fixation and has a beneficial effect on some crops.

organic fertilizer

Organic fertilizer is a carbon containing material derived from plants and/or animals, applied to soil to provide plant nutrition as its main function. Including various organic acids, peptides, and rich nutrients such as nitrogen, phosphorus, and potassium.

Generally refers to human and animal manure, straw, animal waste, cake fertilizer, compost, compost, biogas fertilizer, green manure, and manure.

Not only can it provide comprehensive nutrition for crops, but it also has a long fertilizer effect, which can increase and update soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity; It can enhance the stress resistance, drought resistance, cold resistance, and adaptability to adverse environments of crops. It has created a coordinated environment of water, fertilizer, gas, heat, and environment for the growth and development of crops, laying a solid foundation for high and stable yields.

Biological fertilizer

Biological fertilizer generally refers to microbial fertilizer that incorporates microbial strains, also known as bacterial fertilizer. In addition, there are also bio organic fertilizers processed through beneficial microbial fermentation.

Bio organic fertilizer: Bio organic fertilizer contains various beneficial microorganisms, amino acids, peptides, enzymes, and antibiotics for microorganisms. The main function is to directly supplement carbon nutrition, improve the microbial environment and physical structure in the soil; Inhibit plant pathogens and enhance the plants own immunity; Improve the quality and storage tolerance of crops.

Bacterial fertilizer: The bacterial strains generally include Bacillus subtilis, Trichoderma viride, etc., which can significantly enhance the regeneration ability, nutrient absorption ability, and root rot resistance of crop roots. Some biofertilizers also add Penicillium purpureum, which not only supplements soil organic matter and microorganisms, but also prevents soil nematode diseases, achieving the integrated function of medicine and fertilizer.

Biological fertilizers have unparalleled effects on improving soil microecological environment, stimulating crop growth, and enhancing crop disease and pest resistance compared to chemical fertilizers.

The above are the effects of various fertilizers. However, it should be noted that the more fertilizers applied, the better. For trace element fertilizers, excessive application of one element can also lead to the absorption of another element by crops. So the amount of fertilizer should be determined based on actual needs.
