Compost
Take advantage of this eco-friendly and high nutrition compost. We produce compost that is highly effective and genuine at
Odongunyan Compost Plant, Ikorodu. Compost being an inexpensive alternative to chemical fertilizers, is less likely to harm
sensitive roots. While chemical fertilizers can be extremely harsh on plants, leaving heavy metals like lead, arsenic and cadmium
that can build up over time, killing the very microbes that make soil fertile, also condemning farmers to depend on using chemical
fertilizers over and over again, compost does not. Earthcare  Incorporated delivers 250 bags of organic compost daily.

The Process
The production of compost is both a mechanical and a biological process.
The raw materials must first be separated, collected, and shredded by mechanical means “before the biological decomposition
process can begin. In some cases, the decomposition process itself is aided by mechanical agitation or aeration of the materials.
After decomposition, the finished compost is mechanically screened and bagged for distribution.
Every few weeks, a special machine straddles each windrow and moves along its length to turn and agitate the material. This
breaks down the material into even smaller pieces and exposes it to oxygen, which aids in the decomposition process. After the
windrow is turned, it is sprayed with water again. This process continues for two or three months. In hot, dry weather, the windrows
may have to be watered more often.

 Curing:
The raw compost is scooped up with a front loader and moved to a large conical pile
where it is allowed to finish the decomposition process over a period of several
weeks. This process is called curing and it allows the carbon and nitrogen in the
compost to adjust to their final levels.

Screening:
After the compost has cured, it is scooped up with a front loader and dumped into the
hopper of a rotary screen. This device consists of a large cylindrical screen rotating on
an axis that is slightly inclined above the horizontal. The openings in the screen are
about 0.5 in (1 cm) in diameter. The compost is fed into the raised end of the rotating
screen from the hopper by a conveyor belt. As the compost tumbles its way down the
length of the rotating screen, the smaller material falls through the screen and is
moved to a storage pile by a conveyor belt. The larger material that cannot pass
through the screen falls out the lower end of the cylinder and is either returned to the
compost piles for further decomposition or is sold as wood chips.

Quality Control:
The compost is tested to ensure it is free of harmful materials and contains the proper
amounts of plant nutrients. The tests measure the size of the particles, moisture level,
mineral content, carbon-to-nitrogen ratio, acidity, nutrient content, weed seed
germination rate, and many other factors

Benefits of compost:
Cheaper than chemical fertilizer              Gradually releases nutrients
Diverts waste from the landfill                  Less stressful on roots
Loosens soil                                     Allows roots to spread out widely, preventing erosion
Retains water like mulch                          Accelerates nutrient cycling
Sustainable improvement to the soil
Reduces run-off and water pollution       Eco-friendly
