Almost all people who grow vegetables tend to use organic fertilizers, because vegetables grown with organic fertilizers are not only environmentally friendly, but also taste better. There are many kinds of organic fertilizers on the market, but many farmers do not know the specific ingredients of organic fertilizers very well, such as which organic fertilizers have high nitrogen content, which have high phosphorus content, which have rich potassium content, which can effectively improve soil structure, and which organic fertilizers have long-lasting fertilizer effects. This article aims to introduce all aspects of organic fertilizers in depth, let us learn together.
Which organic fertilizers have high nitrogen content? Which have high phosphorus content? Which have high potassium content?
Almost all organic fertilizers contain three main nutrients: nitrogen, phosphorus, and potassium, but their contents are different. Organic fertilizers with high nitrogen content include human feces and urine, chicken manure, pig manure, bean cake, peanut cake, sesame cake, etc.; those with the highest phosphorus content include chicken manure, fish intestine fertilizer, human feces and urine, bone meal, etc.; and those with high potassium content include plant ash, human feces and urine, chicken manure, pigeon manure, etc. In addition to these three main nutrients, organic fertilizers contain almost all the nutrients needed for plant growth.
Which organic fertilizers can effectively loosen the soil?
A variety of organic fertilizers can improve soil structure, such as various animal manure, crop cake fertilizer, plant green manure, etc. Organic fertilizers with high crude fiber content, such as cow, sheep and horse manure, fertilizers made from leaves, pine needles, rice husks, and edible mushroom sticks, are particularly suitable for loosening soil. These fertilizers are rich in crude fiber and are high-quality materials for improving soil. However, to improve hardened or compacted soil, the effect of a single use is limited, and long-term continuous use is required to significantly improve the soil structure.
Which organic fertilizers are strong?
There are many types of organic fertilizers, and their fertility, fertilizer efficiency and fertilizer strength vary. Organic fertilizers with strong fertility include chicken, duck and goose manure, human feces and urine, pig manure, sheep manure, bean cake, peanut cake, etc. These fertilizers have high nitrogen content and can provide sufficient base fertilizer for vegetables to support their growth. However, these fertilizers must be fermented and decomposed before use. In contrast, fertilizers made from cow and horse manure, vegetable leaves, tree leaves, etc. are weak in fertility and need to be mixed with other fertilizers when growing vegetables.
What is the uniqueness of organic fertilizer?
Organic fertilizer is one of the oldest types of fertilizer used in agriculture. In the era when chemical fertilizers were not yet popular, crops were basically grown on organic fertilizers. Organic fertilizer is not just a simple fertilizer, it has the following characteristics and effects:
a. Comprehensive nutrients and long-lasting fertilizer effect. Organic fertilizer contains not only nitrogen, phosphorus, and potassium, but also various trace elements, which almost meet all the nutritional needs of plant growth. Compared with chemical fertilizers, organic fertilizers have a longer-lasting fertilizer effect and can remain effective in the soil for many years.
b. Organic fertilizers are rich in organic matter and humus, which are the key to improving soil structure, increasing the number of beneficial bacteria in the soil, and improving soil fertility. If the soil lacks organic matter and microbial activity, even if a large amount of fertilizer is applied and managed properly, it will be difficult for crops to grow healthily. These characteristics reflect the important role of organic fertilizer in the soil.
In the soil, if there is a lack of organic matter, the number of microorganisms will also decrease. Once the role of microorganisms is lost, the roots of plants cannot get good growth conditions, and the root development will naturally be affected. At this time, even if more chemical fertilizers are applied, it is difficult to achieve the desired effect. Therefore, in the process of vegetable cultivation, the continuous application of organic fertilizers is the key to the sustainable development of agriculture.
