- increased flowering
- increased water holding capacity of soil by up to 30%
- use on any plant as all natural and organic
- improves fruit and flowers
- helps to de-compact compacted soil
- adds beneficial biology back into soil and on to plant leaf surfaces
- minerals and nutrient in plant available form
- all the benefits of compost in a liquid form
- cost efficient
Least cost production, least power consumption (almost none).
Availability of raw materials (Cow dung)
Simplicity of infrastructure and components.
Environment friendly production.
- Improves its physical structure
- Enriches soil with micro-organisms (adding enzymes such as phosphate and cellulose)
- Microbial activity in worm castings is 10 to 20 times higher than in the soil and organic matter that the worm ingests
- Attracts deep-burrowing earthworms already present in the soil
- Improves water holding capacity
- Enhances germination, plant growth, and crop yield
- Improves root growth and structure
- Enriches soil with micro-organisms (adding plant hormones such as auxins and gibberellic acid
- Biowastes conversion reduces waste flow to landfills
- Elimination of biowastes from the waste stream reduces contamination of other recyclables collected in a single bin (a common problem in communities practicing single-stream recycling
- Creates low-skill jobs at local level
- Low capital investment and relatively simple technologies make vermicomposting practical for less-developed agricultural regions
- Helps to close the "metabolic gap through recycling waste on-site
- Large systems often use temperature control and mechanized harvesting, however other equipment is relatively simple and does not wear out quickly
- Production reduces greenhouse gas emissions such as methane and nitric oxide (produced in landfills or incinerators when not composted or through methane harvest
All About Worms: What is vermicomposting? Why use worms?
Known also as worm compost, vermicast, worm castings, worm humus or worm manure, vermicompost is similar to plain compost, except that it uses worms in addition to microbes and bacteria to turn organic waste into a nutrient-rich fertilizer. Vermicompost, or vermiculture, most often uses two species of worms: Red Wigglers ( Eisenia foetida) or Red Earthworms ( Lumbricus rubellus) rarely found in soil and are adapted to the special conditions in rotting vegetation, compost and manure piles.In temperatures of 15–25 °C (59-77 °F). They can survive at 10 °C (50 °F). Temperatures above 30 °C (86 °F) may harm them.
Not only does composting have agricultural benefits, it also combats climate change. When plant wastes are sent to landfills they turn into carbon dioxide and methane, two of the most common greenhouse gases. When those plants are composted, they lock up carbon from the atmosphere for decades! And when you compost and add that compost to your soil, you are also sequestering additional carbon dioxide.A silt-loam soil weighs roughly 85 pounds per cubic foot. Eight inches of it weighs 56 pounds per square foot. Organic matter is about 58 percent carbon. So soil with one percent organic matter contains (one percent of 58 percent of 56 pounds) 0.3 pounds of carbon per square foot. Soil with 7.7 percent organic matter contains 2.5 pounds of carbon per square foot.
Compost is not just decayed organic matter. Composting is applied microbiology at its most complex, involving the interactions of thousands upon thousands of different species of microorganisms (2 million individuals per gram) in a highly complex ecosystem. The composting process kills weed seeds and suppresses human and plant pathogens; that doesn't happen when leaves and other detritus rot down on their own.
Once applied, compost "balances" the soil flora: that is, for each of the scores or more of disease organisms that can affect each species of plant, at least 12 to 15 different species of bio-control microorganisms need to be present, with the food and conditions they require, if the plant is to be healthy. Composting accomplishes that, among other things. One of the major benefits bacteria provide for plants is in helping them take up nutrients. Some species release nitrogen, sulfur, phosphorus, and trace elements from organic matter. Others break down soil minerals and release potassium, phosphorus, magnesium, calcium and iron. Still other species make and release natural plant growth hormones, which stimulate root growth.
"A few species of bacteria fix nitrogen in the roots of legumes while others fix nitrogen independently of plant association. Bacteria are responsible for converting nitrogen from ammonium to nitrate and back again depending on certain soil conditions. Other benefits to plants provided by various species of bacteria include increasing the solubility of nutrients, improving soil structure, fighting root diseases, and detoxifying soil."
Other soil organisms covered: earthworms, arthropods, fungi, actinomycetes, algae, protozoa, nematodes (mostly beneficial): "All these organisms -- from the tiny bacteria up to the large earthworms and insects -- interact with one another in a multitude of ways in a whole soil ecosystem." Total weight of soil organisms per acre of healthy topsoil: about 4 tons.
Real composting has been a scientific process since the 1930s. In fact it's nothing new -- the Spanish Arabs were master composters, and Chinese peasants have composted virtually everything for centuries.
