OUR PRACTICES SET US APART...
At Green Lea Organics (OPC) Private Limited, we hold ourselves to the highest standard and believe in full transparency with our customers.
For that reason, our production process includes many rigorous practices & procedures to ensure the end result is the best it can possibly be.
Take a look at our key features below.
VERMICOMPOST METHODOLOGY
HOW WE DO IT
We use the windrow system alongside the tetrabed system for effective production of vermicompost over flat land. The level of nutrients in vermicompost depends upon the source of the raw material and the species of earthworm. Our primary ingredient is livestock (cows & buffalos) waste. This is first treated to naturally release all the methane gas over a period of 15 days before being used as feedstock for the worms. We utilize pure bred red wiggler worms, scientifically known as ‘Eisenia Foetida’ which are the most efficient species in compost making. These worms consume organic waste and reduce its volume by 40 to 60 percent, providing a major profile of the most nutrient-rich compost available to us. Azadirachta indica - commonly known in India as; 'Neem', is also added to the mix to derive a strong insect and disease repellant vermicompost.
BIO-COMPOST METHODOLOGY
HOW WE DO IT
Our Bio-compost is made by collecting our own cattle’s dung and urine in a manner which makes sure no outside debris are mixed with it. It is then fed into a 240m³ biogas digester. After anaerobic oxidation of the dung within the digester, a biogas slurry rich in nutrients is collected in multiple underground tanks. This slurry is further dewatered to separate the solid organic manure from the liquid organic manure. This solid organic manure along with the liquid organic manure are further enriched with specific protective & nutritive microbes, converting inorganic forms of Fe, Mg, K, P, etc into absorbable organic elements that can easily be assimilated by plants.
These microbes also assist in safeguarding plants against fungal diseases and maintain the proportion of N:P:K in the soil, thus creating a rhizosphere effect for the plant.
STORAGE PRACTICES
We store onsite with utmost care so that our product reaches you in the most optimal condition.
To study the effects of storage conditions on vermicompost, we experimented with freshly prepared, un-dried fresh vermicompost (60% moisture), and pre-air dried vermicompost (30% moisture) stored in polythene bags for a period of four weeks under different moisture and aeration conditions.
Three different storage conditions were tested by placing fresh and pre-dried vermicompost in:
(1) Open bags, (2) Holed bags and (3) Sealed bags.
Vermicompost properties were analysed weekly for four weeks after storage. The moisture content declined in both fresh and pre-dried vermicompost, with a maximum decline under open bag condition, followed by holed and sealed bags. In the sealed airtight bags with fresh vermicompost, a decline in total organic carbon, nitrogen and electrical conductivity was observed during the first and second week of storage, possibly due to microbially triggered volatilization losses. However, such decline was lacking in pre-dried vermicompost. In open and holed bags, the carbon and nitrogen were retained and rather increased during storage, possibly due to ongoing aerobic decomposition and no volatilization losses. The highest nutrient quality was observed under pre-dried holed bag conditions, possibly due to optimal microbial activity releasing nutrients, combined with no volatilization losses.
It was concluded that fresh vermicompost must be air-dried before its storage in bags as it appears to be the best option for retaining nutrients and quality of vermicompost. We utilize this process for all our packaging.
