Microbial Compost: Base for Sustainable, Environment-Friendly Organic Agriculture

Posted: Tuesday, August 15, 2017

Pursuing organic agricultural production and improving the quality of agricultural products to ensure food hygiene and safety and environmental friendliness are targets of Vietnam's agricultural sector in general and aspirations of farmers in particular. And, one of the most effective measures in organic agricultural production is the widespread use of biological products and microbiological organic fertilisers, instead of plant protection chemicals and chemical fertilisers which negatively affect the environment.

It is easy to identify outstanding advantages of organic fertilisers over chemical fertilisers if the two are compared. Although chemical fertilisers make plants grow strongly, their effects do not last long. In addition, they leave residues in the soil that cause unpredictable consequences such as preventing crops from absorbing necessary nutrients, destroying useful microorganisms necessary for the plant growth, increasing the susceptibility of plants to diseases. Moreover, they can affect the environment and human health.

Meanwhile, organic fertilisers improve the fertility of arable soil, thus helping plants to grow well and strengthen their resistance to pests and diseases. They also help farmers and their crops live in a safe and clean environment. Using organic fertilisers will create an environmental balance and importantly treat organic residues that pollute the environment into fertilisers. Especially, farm products organically produced will limit toxic residues and ensure safety to investors.

With more outstanding advantages, higher efficiency and safety for the environment and user health, microbiological fertiliser is therefore considered the first choice as a substitute for chemical fertilisers. Catching trend, Bioway Organic Vietnam Company (Bioway Hitech Fertiliser Joint Stock Company) officially signed an agreement on sole reception of Bioway AT-12H super-fast fermentation technology from Bioway Organic USA Company (United States). This event was expected to make a big breakthrough in the domestic organic fertiliser market because it was the first time Vietnam received a licence for the fastest and only recognised fermentation system in the world. With this technology, all organic wastes from animal manure, animal carcasses, aquatic waste to crops and agricultural by-products are used to make organic fertilisers in a short time, perhaps less than 12 hours without polluting the environment because of high temperature sterilisation.

Bioway Hitech Fertiliser Joint Stock Company, located in An Nghiep Industrial Park, Chau Thanh district, Soc Trang province, specialises in producing microbiological fertiliser on modern technological lines imported from the United States. This is the largest and most modern microbiological plant in the Mekong Delta. Its main products include organic fertilisers, organic mineral fertilisers, microbiological fertilisers and bio-organic fertilisers. All of these products provide essential nutrients for plants, thereby bringing high economic efficiency to farmers and meeting environmental protection requirements. Particularly, Bioway Hitech organic fertilisers can completely replace imported organic products and a part of NPK fertilisers thanks to outstanding properties with seven groups of substances needed for crops and soil, including macronutrients, secondary nutrients, micronutrients, bacterial enzymes, organic humus, biological substances and biological growth stimulants.

Bioway Hitech organic fertilisers are produced from high-speed fermenters with the A-T microbiological system in a duration of 12-18 hours. High-temperature microorganisms imported from Bioway Organic USA Group are segregated from a new-generation microorganism volcano consisting of microorganism groups: nitrogen fixation (Azotobacter chlococcum), phosphorus decomposition (Bacillus megaterium var phosphorin) and cellulose decomposition (Trichoderma, Actinomyces). High temperature (120ºC) facilitates microorganisms to activate and rapidly clone. After being dropped into the soil, microorganisms continue to activate, decompose organic substances, generate necessary nutrients for plants and particularly resist pathogenic microorganisms against humans and crops in the context of increased poultry-livestock epidemics.

Always placing prestige and product quality on top, Bioway Hitech Fertiliser Joint Stock Company has also built product research laboratories to assess input and output quality and coordinated with research institutes to generate high-grade crops with low cost, high quality and best efficiency.

Ms Le Thi Cam Tien, General Director of Bioway Hitech Fertiliser Joint Stock Company, said, with the operating motto of ‘Environment-Quality-Efficiency,’ the company selects inputs from agricultural by-products rich in nutrients such as chicken manure, aquatic by-products, sugarcane compost, and rice waste, thus helping clear pollutants at many factories and livestock farms in Soc Trang province. Especially powered by modern microbiological technology, these substrates together with high-temperature microorganisms will be fermented at a high temperature of 100ºC - 120ºC for 12 hours to remove harmful microorganisms in the substrate and make environment-friendly organic fertilisers. “Although there are many microbial organic fertiliser producers, most of them use the traditional organic composting process, resulting in a long time of incubation (3 - 12 months) and thus affecting the environment while being unable to eliminate harmful microorganisms,” she said.

Bioway high-quality microbial fertilisers help improve soil properties significantly, help balance nutrients in the soil, provide high nutrient content for crops, particularly fruit crops (like dragon fruit, grapefruit, mango, orange and banana), vegetables, and other crops (rice, maize, sweet potato, cassava, cashew, coffee, and pepper). According to experts from the Department of Crop Production under the Ministry of Agriculture and Rural Development, in developed agricultural countries, using microbial fertiliser is becoming more common while the use of chemical fertilisers in agriculture is decreasing. Especially, in advanced countries such as Japan, the United States, New Zealand, the Netherlands, the United Kingdom, organic fertilisers may make up 40 per cent.

Meanwhile, in Vietnam, most farmers are unfamiliar with using organic fertilisers in agriculture. Even, many people continue to abuse chemical fertilisers that lead to rapid soil degradation and waning crop productivity. “In this context, it is very important to communicate on the benefit of using microbial fertilisers, helping farmers reduce reliance on chemical fertilisers and shift to sustainable farming with least impact on the environment. This is also an important foundation for Vietnam to gradually shift from chemical-based agriculture to sustainable organic agriculture, therefore helping increase the value of agricultural products and produce quality, environment-friendly products,” she said.
