Experts guide how to

Surely the 'town farmers' will be happy to learn that, only from soybeans can a form of organic ' super fertilizer ' be used to solve the long conundrum: ' How to make vegetables, flowers grow well without having to use potential chemical fertilizers to affect their health? '.

Soybeans are a type of seeds that are so familiar to our Vietnamese people. With very high nutritional value: 10-25% lipid, 10-15% glucide, lots of mineral salts, vitamins and especially up to 40% of the ingredients are protein, soybeans have long been evaluated as a food nutritious and capable of replacing meat and fish in daily diets.

Aside from being a dish, it is unlikely that urban residents will suspect that from this kind of seed we can create one of the most advanced organic fertilizers for plants.

According to the agricultural master Le Thi Thu Hang: 'It is difficult to have a fertilizer that is both natural and healthy, and can provide a great source of nutrition for plants not inferior. are all kinds of chemical fertilizers like soybean ".

Master of Agriculture Le Thi Thu Hang.

Specifically, soybean fertilizer products will provide a full range of medium, medium and micro sources and amino acids, especially humic acids, to help plants absorb nutrients easily and use fertilizers in a thorough manner (According to the results). Research by scientists: when applying conventional fertilizer, the plants only absorb up to 50% of nutrients, the remaining 50% is washed away, insects are absorbed .). Besides, soybean feces have 40% of plant protein, so it only lost a few percent of nitrogen in urea (46% protein).

Normally, there are two ways to brew soybeans into fertilizer: 'powder' and 'water'. However, because soybean feces in the form of water smells very unpleasant, inconvenient in the process of preservation and use, we only recommend to you readers soybean meal in powder form - very suitable with households in the city, through the sharing of experts Thu Hang.

How to make soybean meal in powder form

We need to prepare the following main materials:

1. 100kg of soybeans (minced)
2. 50kg of pure phosphorus
3. 2kg of fungal antagonist Tricoderma

In addition, you can add bat manure, 'EM' to increase composting performance, nutrient content as well as reduce odors due to the composting process.

After the ingredients are ready, we just need to mix them together and put them in a sack (already lined with a plastic layer to keep the heat), sealed the bag and incubated for 3 months can use.

Soybean preparations after incubation can be divided into small bags for ease of use.

Thu Hang also added: 'For families with low demand, people can reduce the amount of materials but need to ensure the ratio between components!'.

How to use soybean

Soybean meal can be used to fertilize both ornamental plants and vegetables. When fertilizing we do it the following way:

1. For vegetable beds , sprinkle in powdered form directly onto the soil with a dose of 1 kg of inoculant for 1.5 to 2 square meters of vegetables. Because soybean feces have an unpleasant smell, we need to stop fertilizing about 3 days before harvesting the vegetables.

1. With bonsai , cultivate the soil around the stump and then directly spread the powder form in the root of the root zone. Big trees are good for fertilizing 0.3-0.5kg / tree, and young plants apply 0.1-0.3 kg / tree.

Note : After fertilizing, cover with coconut fiber or straw to keep the plants moist as well as avoid sunlight to make fertilizer around the metamorphic tree, especially when it helps to water. Flush straight into the soil and limit the fungus to the plant. In addition, to ensure the best effect, also apply preparations 1-2 times a month.

Uses of soybean feces

According to Master Hang, the fertilization of soybean for plants will bring the following benefits:

1. Provide adequate and balanced nutrition for plants: Da - Trung- Vi, vitamins, mineral salts and amino acids for plants.
2. Help harden trees, turn on many buds and sprout buds, big, dark and durable flowers.
3. Increasing the density of beneficial microorganisms in the soil, making the soil porous, nutrition is kept, absorbed and used thoroughly.
4. Preventing, increasing resistance and limiting disease to plants.
5. Limit yellow leaves, deciduous trees, making it easy to thrive.
6. Decomposes the insoluble substances and toxins in the soil.
