What Is Worm Manure? Is that good? How much?

Vermicompost is a kind of “food” for plants and crops in agriculture. So what is the specific use of this fertilizer? How to get manure from earthworms as well as how to use fertilizer in the most reasonable way? Let’s find out with BSF Smart Farm right in this article.

What Is Worm Manure?

Worm manure is also known as red worm manure, earthworm manure. Worm manure is the feces of earthworms, worms eat dairy cow dung, through the decomposition process of microorganisms in the worm intestine, dairy cow dung is converted to create the final product, vermicompost. This is a nutrient-rich organic fertilizer that stimulates plant growth.

Why is Cinnamon Compost Good?

In vermicompost, there are active organisms such as molds or bacteria that help fix free nitrogen or break down biological catalysts. These nutrients are also very soluble when dissolved in water. Most of this humus can be found in the ground and used to create a growing medium for plants. The pH of earthworm manure is = 7 pH – suitable for plants.

Nutritional Composition In Worm Compost

  • Vermicompost provides essential minerals for plant growth such as nitrogen 1.57%, effective phosphorus 1.24%, effective potassium 0.67%, calcium 2.14%, magnesium 0. 52%.
  • The vermicompost has abundant and abundant microorganisms such as: nitrogen-fixing microorganisms with a content of 4.2×107 CFU/g, phosphorus-degrading microorganisms of 2.6×106 CFU/g and cellulose-degrading microorganisms with a content of 2. ,0×107 CFU/g.
  • In organic fertilizers, the organic matter content must be over 20%, the vermicompost has a high organic matter content of 48.4%.
  • In addition, vermicompost also contains a large amount of Humic Acid 7.01% and Fulvic Acid 5.63% which are the two main components that make up humus compounds to help retain nutrients and increase the efficiency of fertilizer use for plants. grow.

In vermicompost, there are no harmful agents such as: heavy metals (lead, mercury, arsenic, …), E.coli pathogens, harmful bacteria, insect eggs detrimental to plants, etc.

Common Types of Worms

  • Worm compost powder: is the most common fertilizer for plants. Powder form is rich in nutrients, moisture, and microorganisms. It is used to provide nutrients to the plant, helping the soil to aerate. Suitable for clean vegetables, ornamental flowers, fruit trees. Fertilizers are often used for priming or top dressing.
  • Vermicompost in the form of tablets: This is a fairly common form of vermicompost when asked how many types of vermicompost are common for plants. Stool is compressed into round cylinders. This type of fertilizer is reduced moisture but still ensures quality, good for plants. The tablet form has the advantage of being clean, convenient to use and easy to store. Especially, compacted fertilizers also have the ability to last long. Helps regulate nutrients slowly while increasing replenishment time. Suitable plants are orchids, roses, bonsai.
  • Worm plague: This is considered a new generation fertilizer for plants. Made by hydrolysis of fresh earthworms with probiotics. Wormworm juice has many advantages thanks to the addition of multi-, medium- and micro-nutrients. This fraction is used by dilution with water. This fertilizer is suitable for flowers, vegetables, citrus trees, fruit trees, etc.

The Effect of Worm Manure

  • Worm manure stimulates germination
  • Adding beneficial microorganisms to improve soil
  • Provide organic humus, increase resistance, reduce toxins
  • Stable pH helps plants absorb nutrients easily
  • Vermicompost provides essential minerals for plant growth such as nitrogen, phosphorus, potassium, calcium, magnesium, etc.
  • At the same time, it also contains manganese, copper, zinc, cobalt, borate, iron.. These substances can be absorbed by the plant immediately, there will be no risk, or burning occurs when worm fertilizer is applied.
  • Repel plant diseases thanks to humus substances in eliminating toxins, harmful fungi and harmful bacteria in the soil.
  • Prevents plants from absorbing more mineral complexes than they need because fertilizers have the ability to fix heavy metals in organic waste
  • The pH of manure helps plants grow in moderate soil pH conditions
  • Stimulates the growth of plants and bacteria in the soil thanks to the humic acid and indole acetic acid present in the manure
  • Reduces the carbon acid content of the soil and increases the nitrogen concentration in a state that can be absorbed by the plant
  • Increases the water holding capacity of the soil,  contributes to making the soil porous and retains moisture for a long time

How to Use Worm Compost

Stimulating germination

Use 20 – 30% vermicompost mixed with soil, considered as the best germination mixture to ensure that the plant grows continuously for 3 months without any other food. Has the ability to increase the germination rate of seeds, help seedlings grow quickly and have a high survival rate.

Growth regulator

If you put vermicompost and water regularly on a barren land that has been excavated, this soil layer will be improved significantly (3000 – 3500 kg/ha).

Organic fertilizer

Putting vermicompost directly around the base of the tree (doesn’t cause damage to the tree if used a lot) to fertilize trees, vegetables, and fruits of all kinds will create a high-quality food and high yield.

Liquid fertilizer

Mixable with water at a ratio of 1/5, this liquid mixture can be used as a superior fertilizer and has the ability to control pests when sprayed directly on stems and leaves.

Land improvement

Since vermicompost contains thousands of worm cocoons/kg, when we fertilize the soil with vermicompost, under favorable conditions, the worm cocoons will hatch and live on our own cultivated land – which we all know. Where worms live, the soil is always fertile and porous.

Worm Worm Fertilizer Dosage

  • Growing ornamental flowers: mix vermicompost and soil in a ratio of 3:5 or based on the specific needs of ornamental plants.
  • Growing vegetables at home: mix vermicompost and soil in a 1:1 ratio, no need to add any other fertilizers.
  • Growing sprouts: put 1kg of vermicompost into a plastic box about 1 inch long x wide, then drop the seeds in to harvest the sprouts.
  • Mass planting: use about 250kg to 300kg of worm manure for every 1000 square meters of land.
  • Planting fruit trees: each plant fertilizes 1/2kg or 1kg of worm manure. Fertilize 1-2 times a year only.
  • Growing pepper plants: 1 year, apply 1-2 times, each time apply 1kg or 2kg for the pepper venom.

Notes When Using Compost

Firstly, adding the antagonistic fungus trichoderma to increase the resistance to pathogens for plants to multiply, vermicompost does not have this strain, so we need to add it immediately when applying.
Second, after every 10-15 days, it is necessary to add probiotics or vermicompost, because the wormwood itself will have beneficial microorganisms that vermicompost possesses.

Make your own Worm Manure at Home

Prepare material

– Sponge, plastic bucket, … with tight lid.

The soil area has moderate moisture.

Some organic substances can be used as food for earthworms:

+ Leftover rice

+ Rice water, bean pods

+ Soybean meal (bean corpse)

+ Discarded vegetables

+ Fruit peels

+ Cow fertilizer

+ Pig manure

– Worm biomass.

– Nylon tarpaulin

How to Make Worm Compost

Step 1: Put the foam box or plastic buckets in a cool place, the box must have a lid to prevent rain, rats, cats, and insects.

Step 2: After preparing the box, then add organic waste vegetables including rice water, bean pods, bean residues, leftover rice, vegetable stems such as water spinach, spinach, fruit peels such as bananas, watermelons… put in the container.

Step 3: Prepare worm biomass: you can get earthworms by buying fertilizer for plants or buying biomass from worm farms.

Step 4: Next, for every 1 layer of wet soil, add 1 layer of organic waste to the bin. If there is vermicompost, it should be added because the vermicompost contains many eggs and worm cocoons.

Step 5: Next, put about 2-7kg of worm biomass in the pot and spread evenly, the number of worms depends on your needs.

Step 6: Take care

– Add food for the worms with organic waste such as: peas, fruit peels, chopped vegetables but do not add grease. Sometimes you should soak the cardboard in water to soften, tear it up and pour it into a bucket to raise the worms to increase carbon. The amount of food should be as high as half a pot.

Use a lid to cover the pot to create a favorable living environment for earthworms.

– About 3-4 days watering the rice in a corner of the pot so that the water gradually seeps into the pot to create moisture for the worms to develop.

– If there is fresh cow dung, mix it with water and then pour it into the worms to eat, do not put fresh manure directly because it will affect the compost bin, causing an unpleasant smell, …

Step 7: Harvest: After one month of incubation, it is observed that the vermicompost is brown, porous, has no odor and has many baby worms, which can be used to fertilize clean vegetables.
