What is Bio-Slurry: A beginner’s guide?

Anaerobic digestion in a food waste treatment system produces two by-products namely Biogas, and Bio-slurry. A lot of Bio-slurry is produced in India, as of now, their disposal is a major concern for the environment. This article gives you knowledge on the potential use of Bio-slurry obtained from food waste treatment, which is a viable solution for the reproductive growth of field crops in the long-term. This Bio-slurry can be used as organic fertilizer which acts as a plant growth stimulator and organic fungicide. All kinds of organic residues and wastes such as vegetable waste, food waste, kitchen waste, garden waste, citrus fruits, meat, oil, and egg can be fed as input materials to CHUGG- food waste treatment system, therefore, the residue of the anaerobic digestion that comes out as sludge is rich in organic matters, making it a high-grade soil conditioner. 

How CHUGG produces Bio-Slurry?

Food waste management in India is now easy with an innovative food waste treatment system like CHUGG. All you have to do is crush your kitchen scrapes with water and feed it to CHUGG. The food waste undergoes an anaerobic reaction “in-situ” which means at source. This is to eliminate the emission of Greenhouse gas into the atmosphere. After the anaerobic reaction, the food waste fed into the CHUGG food waste treatment system is digested using Nano-technology. Thereby producing two by-products namely Biogas and Bio-slurry. Biogas is generated and stored at low pressure. Whereas Bio-slurry is produced from the residue of the digestion that comes out as sludge. Bio-slurry is referred to as Black gold by farmers as it improves agricultural productivity by replacing chemical fertilizers. 

Composition of Bio-Slurry

In agricultural nations like India, organic waste matters are generated in enormous amounts, and thus it is feasible for creating biogas and bio-slurry as the result. Therefore, the use of bio-slurry as compost is a viable way to improve the efficiency of the soil. It is affordable and easily accessible manure for farmers who could not afford synthetic fertilizers. Bio slurry nowadays being utilized as a potent soil conditioner for it is enriched with high nitrogen (N), phosphorous (P), and potassium (K) that are viewed as the essential nutrients needed for the prospering development of plants. It additionally contains a few micro-nutrients which help build the fertility of the soil. 

Characteristics of Bio-Slurry

The undigested slurry undergoes a series of anaerobic digestion processes hence it is odorless and does not attract flies, termites, and pests. Application of Bio-Slurry on crops has proved to reduce weed growth by 50%. The Bio-Slurry obtained from the CHUGG food waste treatment system acts as a soil conditioner by adding humus and enhancing the soil’s capacity to retain moisture. The digestion of Food-Waste in the CHUGG kills organisms causing plant disease hence it is pathogen-free. 

Benefits of Bio-Slurry

Soil conditioner as it contains humic acid 

Humic acid present in the Bio-Slurry increases the nutrient supply and hygroscopicity of the soil. In low-humus tropical soils, this humic content is very essential for stimulating plant growth. 

  1. Comprehensive nutrition and high-quality

The decomposition and breakdown of food waste produce digested sludge as a residue which is fast-acting nutrients that enter into the soil easily, thus being readily accessible for plants. They contain all the primary nutrients for the development of soil organisms.

  1. Organic fungicide

Bio-Slurry is an organic fungicide that fights against any disease-causing organisms for plants. It replaces some synthetic pesticides against pests/disease. Proper utilization of Bio-Slurry on crops or plants reduces the growth of weeds by 50%. 

  1. Reduces soil erosion 

Bio-Slurry contributes to more rapid soil-humification, this in turn helps reduce the rate of erosion. It improves soil’s fertility, structure, crop productivity making it an excellent fertilizer. The water-retaining property of Bio-Slurry produced by CHUGG-food waste treatment system helps prevent soil erosion. 

  1. Probiotic microbial-derived bio-activator

The probiotic microbial-derived bio-activator is naturally present in Bio-Slurry produced by CHUGG-food waste treatment system which is a food source for earthworms. Earthworms are farmer’s friends, they stimulate microbial activity, promote plant growth, and reduce soil-borne diseases. 

How Bio-Slurry is better than synthetic fertilizer

  1. Synthetic fertilizers replenish only a small part of nutrients to the soil. Poor management and application of synthetic fertilizer mean not all nutrients are absorbed by the soil. Which means less crop yield. But applying Bio-Slurry for crops has been acknowledged to improve crop yield and retain soil nutrients. 
  2. Synthetic fertilizers are expensive and cannot be affordable for small-scale farmers. The organic matter fed into the CHUGG-food waste treatment system is extensively available and hence is affordable and easily accessible by all farmers. 
  3. Overuse of synthetic fertilizers increases nitrate and nitrate contamination in vegetables, crops become susceptible to insects, microbial attacks, and weeds. Bio-Slurry reduces the growth of weeds and acts as an organic fungicide. 
  4. High ammonia emissions due to over-fertilization using synthetic fertilizers are another growing global concern. Therefore when Bio-Slurry is combined with chemical fertilizer shows much better yields than using Bio-slurry on its own. 
  5. Using synthetic fertilizer reduces soil’s moisture content hence more water is needed for irrigation. Bio-Slurry contains humic acid which retains soil’s moisture content. 

Final Verdict

CHUGG an innovative food waste treatment system in India providing clean and sustainable renewable energy, Biogas, and organic soil conditioner as a by-product. Bio-slurry is excellent organic manure and a great substitute for synthetic fertilizers, regular composts, due to its high nutrient content. It is a perfect solution for the organic animal husbandry with regards to organic waste, composting, and fertilizers. Not only for farming challenges it is a great solution for small-scale framers based on the economic aspects and energy challenges they face day by day. It contributes to building organic bridges between existing and traditional farming practices. Therefore the production of Bio-Slurry should be encouraged as much as possible.
