As we all know, organic fertilizer becomes more and more popular, due to its strong function and obvious fertilizer efficiency. On the other hand, the raw material of organic fertilizer is usually organic waste, such as manure from livestock and poultry, food waste, municipal sludge and so on. Besides common composting ways, you can also adopt vermicomposting technology. And the final products, vermicompost or earthworm dung, is a kind of high-quality organic fertilizer. The vermicompost production include two parts, preliminary production and deep processing. And we will give you a detailed description below.
How to make vermicompost?
The vermicomposting technology utilize the combined effects of earthworm and microorganism to convert organic waste into useful components. There are many types of organic waste can be used as raw materials, such as cow dung, chicken manure, food waste, sewage, strew and so on. Before adding earthworms, you should make the organic waste semi-decomposed. Because the temperature of compost pile may achieve 60℃ to 70℃ at the beginning of composting, which is too high to live for earthworms. After semi-decomposition, the temperature of compost pile will reduce, and you can add earthworms for further decomposition.
By taking advantage of saprophage, euryphage and big appetite of earthworms, you can adopt earthworms to eat organic waste and decompose them by digestion. After some days, the organic matters and inorganic salt will be converted into available vermicompost. This shows that earthworms are an important factor in vermicomposting.
What should you pay attention to during vermicompost production?
The earthworm is alive, therefore you should be more careful than common composting. You should pay close attention to both composting site selection and environment conditions control. The selection of composting site: Because the earthworm may enter the soil. You can not pile up organic waste on the soil directly. On the contrary, you need to choose floor with compact structure, such as concrete floor.
Raw materials for vermicomposting: Semi-decomposed organic waste will be best raw materials for vermicomposting. Because excess heat produced from the compost pile may kill earthworms, you need to add earthworms after composting for a period.
The control of composting conditions: In order to successfully accomplish vermicomposting, you should maintain moisture of the compost pile at 30% to 40% and the temperature at 18℃ to 25℃. what’s more, the aeration is also important for earthworms to grow and decompose organic waste.
The removal of earthworms: When the vermicomposting period accomplishes, you need to remove earthworms for the following operations. There are two methods provided by us. On the one hand, you can make a new organic waste pile and earthworms will migrate to new compost pile from the finished one automatically. On the other hand, you can expose the compost pile under the sunshine, and the earthworm will escape downward. And you can collect the vermicompost layer by layer.
How to conduct deep processing of vermicompost with Tongda equipment?
In order to further processing vermicompost, you need conduct the following steps, mainly including crushing, granulating, screening and packaging process.
Crushing process: Crushing the vermicompost is prepared for granulation. Because granulating process need uniform fertilizer powder. In order to get powder, you can adopt Tongda crushing machine to deal with potential fertilizer caking and make powder that meets the granulation standard. There are new type vertical crusher, semi-wet material crusher for you to choose.
Granulating process: Granulation is the most important step for granular vermicompost production. Granulating machine is necessary in this step, which can convert fertilizer powder into granular fertilizer by wet pelleting. The vermicompost pellets are convenient for storage and application. Therefore, you can adopt Tongda granulator to make granular fertilizer. Our machines for granulating fertilizer power include new type organic fertilizer granalator, rotary drum churning granulator and disc granulator.
Screening process: After granulation, you can apply screening machine to select out pellets with unqualified size so as to ensure the final quality. And the unqualified pellets will be sent back to crushing machine for secondary granulation. This process is mainly for obtaining uniform pellets.
Packaging process: After processing, uniform will be sent to packaging machine by conveying equipment, such as Tongda screw conveyor and mobile belt conveyor. The packaging of vermicompost is mainly for storage and transport in a convenient way. In this process, you can apply Tongda single (double) bucket auomatic packing scale, which can automatically control quantity for each bag. What’s more, the weight of each bag is adjustable, which can meet your different requirements.
What’s the features and functions of vermicompost?
Vermicompost is a kind of high-quality organic fertilizer. For one thing, the production of vermicompost is a natural, ordourless and aerobic process, which is economically friendly. For the other thing, the abundant nutrients in vermiconpost can provide good growing environment. It is rich in nutrients. Besides macroelements and multiple microelements and 18 kinds of amino acids, the vermicompost respectively has 30% organic matter and humus. What’s more, there are some valuable antagonistic microbe and unknown auxin.
Abundant organic matters: The standard for evaluating lands’ fertile degree is the content of organic matters. The organic matters content of vermicompost is 30%, which can be absorbed by soil and plants easily. The application of earthworm dung organic fertilizer can prompt soil aggregate structure, improve soil permeability and water-retaining property, which is favorable for microorganism to live.
Rich in microorganism groups: Earthworm dung organic fertilizer is rich in beneficial microorganism content, which will quickly inhibit the reproduction of harmful bacteria. Meanwhile, the metabolism of microorganisms can improve physical and chemical property of soil, so as to fertilize the soil.
Rich in humid acid: The humid acid content of vermicompost is 21% to 40%, which can improve soil structure and balance PH value. The vermicompost is available for various crops as base fertilizer or top dressing.
In a word, Tongda can provide you various machines for vermicompost production and customized services. If you have demand on organic fertilizer making machines or other related problems, please contact us.
