The main problem when growing vegetables in the courtyard, on the balcony or on the roof is fertilizer. People are reluctant to use chemical fertilizers. Choosing the right homemade fertilizer is a very troublesome issue. Some people say that the cost of using soybeans to make organic fertilizer is too high, but they ignore a core issue, that is, the vegetables you grow at home are for your own consumption. The most important thing is to be able to eat safe and pollution-free vegetables, not to mention the dosage. It's not big and the cost isn't too high.
Effective method of soybean fermentation organic fertilizer:
Burying soybeans directly into the soil, burying them into the soil after cooking, or crushing them and then applying them to the soil as flower fertilizer or vegetable planting will cause undesirable phenomena such as root burning and seedling burning. This can only occur after the soybeans are fully decomposed. This is something that those who grow vegetables and flowers must understand.
If you want to fully decompose soybeans, you can perform preliminary treatment through the following methods:
1. Fermentation after cooking. After soaking the soybeans for 12 hours, the soybeans have fully absorbed water and are then put into the pot and cooked.
2. Fry and then ferment. Place the dried soybeans directly into the pot and stir-fry until fully cooked, then grind finely.
3. Stir-fry briefly and then ferment. Put the dry soybeans in the pot and stir-fry several times. After fully heating, take them out and crush them with the grinder .
Method for decomposing soybeans:
1. Prepare nutrient solution. Put the soybeans that have been initially treated by the above three methods into a container, add more than 3 times of water, then add an appropriate amount of brown sugar water or EM bacteria , and then add an appropriate amount of orange peel, lemon peel or orange peel to reduce the odor. , the container can hold up to 80% of the aqueous solution. After doing all this, seal the container and place it in a sunny place for exposure, using high temperature to accelerate the fermentation rate.
can be completely decomposed in an environment above 30℃ in 7 days. If the temperature is low, it may take 1-2 months to mature. If brown sugar water or EM bacteria are not added, the decomposition time is generally more than 2 months. If the peel is not added, a lot of odor will be emitted during and after the ripening process, making it unsuitable for home gardening.
After the soybean water is decomposed, it needs to be diluted 10-50 times again before watering flowers and vegetables to avoid burning seedlings due to too high concentration.
2. Compost. Add water to the initially treated soybeans. The amount of water added is generally 65-70% of the weight of the soybeans. Then add an appropriate amount of brown sugar water or EM bacteria, orange peel, lemon peel or orange peel, put it into the container, mix well, and then cover it once Wheat bran, rice husk, etc. are moistened, and then placed in a place with a higher temperature for retting.
When the compost starts to heat up, you need to pay attention. When the temperature rises to 65-70°C, stir the soybeans in the container, and then add water to make the moisture content reach about 65%. After turning the pile 2-3 times, when it no longer heats up, it means it has been completely fermented. The fermentation time is generally more than 7 days. The higher the external temperature, the faster the fermentation speed.
The decomposed soybean compost can be used as base fertilizer or can be applied in holes. The fertilizer efficiency is very high. You need to pay attention to the distance from the roots and the amount of use.
3. Mix other materials for ripening. Every household will have various kinds of garbage, including leftovers, swill, rotten vegetable leaves, vegetable roots, bones, animal offal, melon seed peels, peanut shells, tea leaves, indoor garbage, yard leaves, etc., as well as soy milk residue, Rotten fruits, expired food and beverages, etc. are all raw materials for making organic fertilizer. These raw materials are mixed with roughly processed soybeans, and then brown sugar water, orange peels, etc. are added for retting. After a period of time, they can be decomposed. After
is decomposed, it is generally used as a base fertilizer, and it can also be used as a top-dressing fertilizer during the growth period.
Soybean cake is a more affordable alternative to soybeans
In rural areas, in addition to processing and selling the soybeans grown by farmers, they mainly perform oil extraction and edible soybean oil. The by-product is soybean cake, which contains high protein. After being decomposed, it is a good nitrogen fertilizer. and potassium fertilizer can completely replace soybeans as liquid fertilizer or cake fertilizer.
The general processing method is to directly add water to the soybean cake, and then mix it into a paste, add brown sugar water and orange peel to it. After about 7 days, it can be matured into cake fertilizer, which can be directly used as top dressing or used as base fertilizer.
If you want to water flowers and vegetables, or do soilless cultivation , you need to add more than 10 times of water for decomposition, and then use clarified liquid to water flowers and vegetables. The residue can be used as a base fertilizer, and the fertilizer effect is very good.
