Have you ever been troubled by the leftover soybean dregs in your home?In fact, these seemingly useless wastes are the best quality of natural organic fertilizers. Today, we are going to share one of the easiest methods of fermenting soybean fertilizer - making okara fertilizer.
First of all, we need to prepare fresh soybeans. After the soybeans are juiced, the remaining okara is the main raw material for us to make okara fertilizer. These okara are rich in protein, sugars and other nutrients, and after fermentation, they can be converted into nitrogen, phosphorus, potassium and other elements required by plants, which has a significant effect on improving soil fertility.
Next, we need to prepare a plastic bucket or wooden barrel with a lid, clean it and dry it for later use. This bucket will be our "compost bin". Spread a layer of soil about 5 cm thick on the bottom, then pour in a layer of okara and another layer of soil, and repeat until the entire bucket is filled. In this process, each layer of okara is thoroughly mixed with the soil, which helps the decomposition and fermentation of the okara.
In the process of composting, moisture control is very important. Generally speaking, we should maintain proper humidity, hold it in a ball with our hands, and loosen it to disperse. If it feels too dry, you can spray it with waterIf it is too wet, you can add some dry materials such as litter and leaves to adjust the humidity.
After the above work is done, we will cover the barrel and put it in a cool and ventilated place for fermentation. Every few days, remember to open the lid to allow air and turn it with a spatula to ensure even fermentation. After about 2-3 months, the okara will completely ferment into okara fertilizer.
Finally, let's take a look at how to use oka fertilizer. Okara fertilizer can be used directly as a base fertilizer, or it can be diluted and used as a top dressing. When growing crops, mix them into the soil.
Of course, there are some things that need to be paid attention to in the process of making oka fertilizer. During the fermentation process, some gases may be produced, so open the lid regularly to vent the gas. In addition, in order to speed up the fermentation and improve the fertilizer efficiency, we can also add some EM bacteria or other microbial agents to the compost.
Overall, making okara fertilizer is an environmentally friendly and practical way. Not only can it make effective use of household waste, but it also provides us with high-quality organic fertilizer to help us grow healthy and delicious vegetables and fruits. Let's work together to make life greener and better!
