1、 What organic fertilizer is made of
Organic fertilizer is made of human and animal manure, compost, cake fertilizer, grass ash, straw, green fertilizer, rice bran, sawdust, etc. It contains a large amount of organic matter, humic acid, vitamins, etc. it is a good fertilizer for improving the soil in orchard. According to the types, it can be divided into farmhouse manure, stable fertilizer, green fertilizer and cake fertilizer, which is suitable for the application of base fertilizer.
How to configure the humic organic fertilizer?
The compost organic fertilizer is composed of the residues or metabolites of various animals and plants. Generally, the compost is mixed and stirred evenly with straw, mule, horse manure, human urine manure, etc. and then piled into a rectangular pile of water for fermentation. Generally, the temperature of organic fertilizer fermentation is increased to 60 ℃ -70 ℃, and it can be maintained for 6-7 days, so that the fertilizer can be fully fermented and harmful organisms can be killed due to high temperature. If you are worried about the temperature control, you can find a thermometer to measure the temperature. The fertilizer will be fermented to 60 degrees and then it will last for 10 days and it will be almost finished.
2、 What is organic fertilizer
Organic fertilizer is farm manure, such as manure, decayed animal carcasses or decayed plants. Organic fertilizer like pig manure, chicken manure, all kinds of rotten litter, plant ash can do organic fertilizer.
The characteristics of organic fertilizer are wide source of materials, large quantity, complete nutrition, low content, late and long fertilizer effect, which can be absorbed by plants only after microbial differentiation and transformation, and good effect of soil improvement and fertilization. Common natural fertilizers include green manure, human manure, stable manure, compost, compost, biogas fertilizer and waste fertilizer.
Compared with chemical fertilizer, organic fertilizer has more varieties of nutrients, including nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and trace elements, while the latter is relatively simple. Nitrogen fertilizer only contains nitrogen, phosphorus fertilizer only contains phosphorus, potassium fertilizer only contains potassium, and even compound fertilizer only contains nitrogen, phosphorus, potassium and other limited nutrients.
However, although organic fertilizer contains all kinds of nutrients, its concentration is relatively low. Take chicken manure as an example, its nitrogen content is about 1.6, phosphorus content is about 1.5, potassium content is about 0.9, that is, 100 kg chicken manure contains 1.6 kg of nitrogen (n), 1.5 kg of phosphorus (P2O5), and 0.9 kg of potassium (K2O). In chemical fertilizer, urea contains 46 kg nitrogen (n) in 100 kg urea, 60 100 kg potassium chloride and 60 00 kg potassium chloride. The nutrient concentration of chemical fertilizer is much higher than that of organic fertilizer.
Organic fertilizer contains a lot of organic matter, which is not available in chemical fertilizer. After organic fertilizer is applied to the soil, it can release nutrients for crops to absorb after microbial differentiation and decay, while chemical fertilizer can play a role after it is applied to the soil. Therefore, organic fertilizer has many kinds of nutrients, low concentration and slow release, while chemical fertilizer, on the contrary, has single nutrition, high concentration and fast release.
