Introduction of NPK fertilizers:
Plant growth is inseparable from the three elements of nitrogen, phosphorus, and potassium. The common compound fertilizers on the market are also made up of these three elements. Among the nutrient elements necessary for crops, nitrogen, phosphorus, and potassium require a large amount, so nitrogen fertilizer, phosphate fertilizer, and potassium fertilizer are the most important chemical fertilizers. This article mainly introduces the Npk fertilizer manufacturing process for you.
Npk fertilizer manufacturing process:
Production of nitrogen fertilizer
1. The main function of nitrogen fertilizer is to promote plant growth and make plants flourish. Generally, nitrogen fertilizers are used more in the growing season of plants.
Crush and boil the moldy and inedible beans, peanuts, melon seeds, castor, leftover vegetable leaves, bean husks, melon peels or pigeon dung, and expired and spoiled milk powder, etc., and place them in a large airtight container / Fill the fermenter with water, and then seal it to ferment and decompose (sprinkle some pesticides if possible). In order to make it mature as soon as possible, it can be placed in the sun to increase the temperature. When all these substances in the altar sink, and when the water turns black and odorless (about 3-6 months), it means that it has been fermented. (The temperature is suitable between 40—75 degrees
In summer, after 10 days, the upper layer of fertilizer can be taken out and used on the water. It can be used as a top dressing or directly used as base fertilizer. After use, fill up the water and then refill it. The raw material residue can be mixed into the flower soil
2. Boil the edible bean cakes, rapeseed cakes, sauce residues, etc., and store them in the altar, and add an appropriate amount of EM bacteria (the amount of EM bacteria is 120-400 g/cubic), and then inject a small amount of water, and the humidity is maintained at 60%-70 %. After sealing and retting for about a week, the fertilizer solution can be taken out and mixed with water for use.
Stir regularly, 10-15 minutes each time, 3-4 times a day to supplement oxygen and release exhaust gas such as carbon dioxide.
Production of phosphate fertilizer
Pour lamb horns, trotters, bones, fish intestines, poultry manure, fish belly intestines, meat bones, fishbone spurs, fish scales, crab shells, shrimp shells, hair, nails, livestock hoof horns, and miscellaneous bones into the tank and add appropriate EM Add a small amount of water after the bacteria, keep the humidity at 60%-70%, seal it, and mix with water after a period of rot and fermentation. It is a good base fertilizer for the field. If it is brewed and fermented, it will become a vegetable fertilizer rich in phosphorus. The impurities are rich in phosphorus. These impurities are crushed and mixed evenly in the soil, or placed in a container to ferment and become an ideal phosphate fertilizer. Used to water the vegetables, it will make the vegetables bright, bright, and full of fruits. The fertilizer effect can last for more than 2 years.
Note: The principle of the method is the same as the above, and the use of EM bacteria is also the same. The main adjustment is to adjust the proportion of EM composite strains of phosphate bacteria. Pay attention to adjusting the temperature and stirring in time.
Production of potash fertilizer:
Usually leftover tea water, rice wash swill (preferably applied after fermentation with EM/HM bacteria starter), plant ash water, milk bottle water, in addition to those who grow peanuts, you can use peanut bran Or the stalk has the same effect. They are all good potash fertilizers, which can be used directly for watering vegetables. They all contain a certain amount of nutrients such as nitrogen, phosphorus, and potassium, which are used to water vegetables, which can not only maintain soil water but also add nitrogen fertilizer to plants, which can promote the development of roots and luxuriant foliage. Can be used directly to pour vegetables. Plant ash also contains potassium fertilizer, which can be used as base fertilizer. Potassium fertilizer has a significant effect on improving the ability of flowers to resist lodging and pests.
Note: For large areas (50 acres and above), use the stalks of oil crops and follow the above steps. Such as rape, castor, sesame, peanut, soybean, etc., and can increase the content of unsaturated fatty acids in the crops, enhance the cold resistance of the crops, reduce the temperature of the crops to absorb nutrients, and increase the ability of the crops in adversity.
