Seeing that some people grow vegetables so well, are you curious about how this is achieved? The secret lies in the fertilizer. I will help my friends classify and introduce 12 kinds of natural fertilizers that are usually used in vegetable gardens. Anything that can directly or indirectly supply nutrients to vegetables or improve soil and fertility, we call it fertilizer. Nitrogen fertilizers, phosphate fertilizers, potash fertilizers, trace elements and compound fertilizers are all direct fertilizers. There are some fertilizers that improve the growth conditions of vegetables by improving the physical, chemical and biological properties of the soil, called indirect fertilizers, such as lime, gypsum, and bacterial fertilizers.
The first natural fertilizer is: vermicompost
Before humans came to the earth, earthworms had cultivated on the earth for hundreds of millions of years. Various organic wastes in nature are fermented and quickly decomposed under the action of earthworm digestive system protease, lipase, cellulase and amylase, and converted into easily usable nutrients, which become earthworm feces after excretion. Earthworm manure is a product of nature, which can truly fully meet the various needs and nutrients of plant growth, and has incredible magical fertilizer effects on plants. Earthworm feces will not burn plants at any concentration. When you use this natural substance without any peculiar smell, you will once again sigh the magical power of nature.
The second type of natural fertilizer is various manures: sea bird droppings, chicken droppings, mammal droppings, etc.
Sea guano is a fine-particle mixture of seabird, bat or seal excrement mixed with animal and plant residues. Sea guano contains extremely high nitrogen, phosphorus and potassium and other nutrients necessary for plant growth. Nowadays, sea bird droppings are more and more sought after by food friends [1].
Chicken manure: Chicken manure is the animal manure with the most N-P-K content.
Cow manure: Cow manure may be the best animal manure for soil improvement. Cow manure does not contain excess salt and weed seeds. Although the content of nutrients in cow manure is low, it is safe to use. Horse manure: The nitrogen content of horse manure is about half that of chicken manure, which is higher than that of cow manure. Animal manure must be used after it is decomposed.
The bagged manure sold in the store is generally made of various types of poultry manure plus some humus, which has a long-lasting fertilizer effect. various kinds. The contents of nitrogen, phosphorus, potassium and other components are marked on each fertilizer packaging bag. Animal manure soil is a good base fertilizer. It is usually sprinkled on the surface of the soil and then turned over to allow it to fully mix with the soil in the vegetable field.
The third is fish protein fertilizer
Fish protein fertilizer mainly uses deep-sea fish and shrimp, combined with new biological strains and advanced fermentation technology, to extract deep-sea fish protein as the main raw material. It can be used for various fertilization methods such as leaf spraying, flushing, drip irrigation, etc. Fish protein fertilizer is rich in organic matter, fish protein, peptides, etc. Fish protein fertilizer promotes the reproduction of soil microorganisms and activates soil nutrients. It can also promote the development of plant roots, which is conducive to the differentiation of flower buds and improve the quality. In addition, fish protein fertilizer can have a good inhibitory effect on some diseases and insect pests. Fish protein fertilizer can be used to cultivate strong seedlings, improve rigid seedlings, yellow seedlings, etc. It is a pollution-free and environmentally friendly green nutrient fertilizer. We all know that earthworms have a special effect on improving the soil. If your vegetable garden uses fish protein fertilizer continuously for more than one year, a large number of earthworms can be produced in the soil, making the soil loose and fertile.
The fourth type of compost, this is a very large type.
The fifth blood meal, hoof horn meal, bone meal
The sixth variety of cake fertilizers,
The seventh seaweed fertilizer
The eighth humic acid and fulvic acid
The ninth plant ash
Plant ash is the best potash fertilizer, and palm ash is commonly used.
The tenth type of phosphate rock, the main component of phosphate rock is calcium phosphate, which can provide a large amount of phosphorus. If you use phosphate rock powder containing phosphate in your vegetable garden, there
Eleventh bath salt
The twelfth kind of lime, gypsum, etc.
out according to the nature of the soil. Among them, the important consideration is the content of various nutrients in the soil, the ability to maintain fertilizer and supply fertilizer, and so on.
When buying various fertilizers, you can check the fertilizer name and nutrient content indicated on the packaging bag.
