Making fertilizer from sawdust In recent years, it has become a method used by many farmers to grow crops. Sawdust is a natural waste from woodworking. In the past, people often used this type of waste material because they thought they were useless. However, in recent years, when they discovered the useful uses of sawdust in the growth of plants, they have applied it a lot in agriculture.
1. What is sawdust? How does it work in life?
Before sharing about how make fertilizer from sawdustLet’s find out what is sawdust and how does it work? Sawdust is an organic material, derived from industrial woodworking. Specifically, the wood, bamboo and bamboo that are drunk when planing thin will be crushed into small-sized particles. Previously, sawdust was only considered as a natural waste. But today, after finding out the practical benefits that it brings, sawdust is widely used in many different industries.
1.1. What is sawdust used for in farming?
Sawdust is a familiar material in the field of cultivation today. Method of making fertilizer from sawdust increasingly popular, thanks to its many practical benefits. In addition, it is also applied to many different things in agricultural production as follows:
- Mixing the soil with small or medium sawdust makes the soil loose, improves oxygen supply and improves water permeability.
- Adding sawdust to the planting beds during digging will help retain water longer. Plant roots can obtain moisture in the lower layers from moist wood grains.
- Pour sawdust over 5cm high between rows and planting beds to prevent weed germination.
- Putting a layer of sawdust under bushes of zucchini, strawberries, cucumbers, tomatoes, etc. will eliminate contact with the ground, defeating caterpillars.
- Sawdust mixed with ash or urea, piled between beds and crop rows effectively traps water and removes evaporation from the soil.
- In frosty weather, pour berry bushes, bulbous crops, rhizomes of trees and shrubs with sawdust. Wood chips will become a reliable protector in winter cultivation.
1.2. Sawdust used in livestock
Not only make fertilizer from sawdust This material is also widely used in animal husbandry. The mixed sawdust composting method is one of the biological models of animal care with many outstanding advantages. Specifically, sawdust after being removed all harmful substances can be combined with rice husk; help to treat waste better and reduce the effort in cleaning up for people. Besides, this way also minimizes the incidence of livestock diseases, completely friendly to the living environment.
1.3. Application of sawdust in industry
Sawdust is an important raw material, the main ingredient in the production of wood pellets. After being purchased, people will pelletize the sawdust into round pellets. Then burned, under the influence of heat, through a closed production line, sawdust pellets will turn into solid wood pellets. These wood pellets not only ensure safety standards for human health but also help limit emissions into the environment.
2. Instructions on how to make fertilizer from simple sawdust at home
Making fertilizer from sawdust was no stranger to farmers. These small-sized by-products from wood production seem useless but are in fact of great value to plants. But with the condition, they must be brewed by the right method according to the right process.
2.1. The great benefits of fertilizer made from sawdust
Processing fertilizer from sawdust takes a lot of time and effort. However, compared with the benefits that this organic fertilizer brings to plants and soil, it will be worth it. Specifically, this fertilizer product has the following effects:
- Provide essential nutrients for plants such as multi-element – microelements, nitrogen, phosphorus, potassium, vitamins, …
- Retains nutrients, balances pH and creates soil moisture.
- Increase soil humus, improve soil cohesion and drainage. Acts on the soil structure, improves the physical – chemical – biological properties of the soil.
- Ensure safety for people, because it does not contain harmful substances, helping to protect the environment.
- Provide beneficial flora for the soil. Because in sawdust fertilizer contains beneficial microorganisms, which help synthesize nutrients for plants. At the same time, destroy harmful microorganisms.
2.2. Steps to make fertilizer from sawdust properly
Procedure make fertilizer from sawdust includes the basic steps of material selection, composting fermentation, composting, mixing and finishing.
2.2.1. Selection of natural organic ingredients
You should choose and use natural organic materials such as sawdust, bark, leaves, bagasse in the amount of about 500-700kg. All ingredients should be minced or ground as small as possible. Next, water them to moisten at 60-65%, before incubation for about 12 hours; to give them time to evenly absorb the amount of water being irrigated. Test for moisture by grasping a handful of ingredients in the palm of your hand. If you see water oozing out of your fingers, that’s fine.
Besides, with method of composting sawdust as fertilizer then you can add animal manure such as pig manure, chicken manure, buffalo manure, cow dung, etc. This will help increase the nutritional content in the compost later. With 500-700kg of raw materials, about 200-500kg of animal manure is needed. In case the manure is too wet, it is necessary to separate the water or mix more fillers to achieve the required moisture.
2.2.2. Fermentation of compost from sawdust
Fermented yeast to make fertilizer from sawdust including 1 kg of probiotics, mixed with 5-10kg of rice bran, used for about 1-2 tons of fresh ingredients. If you have experience and perform the operation proficiently, you can brew 3-4 tons. However, sawdust, bark, and rice husks are difficult materials to ferment, so the amount used can be increased.
2.2.3. Mix ingredients and pile up sawdust
- Place to compost sawdust: You should choose a place that is dry, cool, easy to drain and away from houses such as planted gardens, vacant lots, etc.
- Mixing ingredients: Bring all the prepared and moistened ingredients together.
- Stacking compost: First, you spread the ingredients evenly into layers, about 10-20cm thick. Then, use brewed yeast mixed with rice bran sprinkled evenly on the layers. Next, cover the compost pile with straw or hay. Make sure each pile is not less than 500kg, the minimum height is 70-80cm, the top is about 1.5-2m above the ground.
2.2.4. Turn the compost pile
In process make fertilizer from wood sawdust, microorganisms with strong decomposition activity will cause the temperature in the compost pile to rise rapidly. After 48 hours, the temperature inside the compost pile can be up to 50-600 degrees Celsius. If the compost temperature exceeds 65°C, you need to proceed to mix the materials as soon as possible and create ventilation for the compost pile. . By using sticks with a diameter of 5-10cm make holes in the pile of ingredients.
2.2.5. Completing the composting process from sawdust
After about 3-4 times of mixing the materials, within 25-30 days, the materials in the compost pile will no longer have a bad smell. Instead there is a slight ammonia or earthy aroma after biological fermentation. If you see a large amount of white mycelium in the middle of the compost pile, the fermentation is complete. Fertilizer from sawdust after forming can be used directly to fertilize plants; or mixed with nutritional ingredients to increase efficiency and quality.
Come here, you already know how make fertilizer from sawdust then right? This is really a fertilizer that provides very good nutrients for plants that you should not ignore.
