Soil Solver products feeds the soil and builds up an earth friend habitat for micro organisms, fungi and plants and boost the long term health and fertility of your garden.
Supplied in a plain green bag.

Compost improves soil structure, increases the water-holding capacity of coarse-textured sandy soils, improves drainage in fine-textured clay soils, provides a source of slow release nutrients, reduces wind and water erosion, and promotes growth of earthworms and other beneficial soil organisms. It provides both food and texture to soil. Sandy ground is best first treated with Soil Solver Clay Plus to hold onto and protect the organic matter. 

Compost maturity is important to product performance. Immature compost may stunt, damage, or even kill plants, rather than enhancing their growth. Maturity is not related to quality, but to what stage in the composting process the material has progressed. 

Not all composts are equal.  A Mature compost takes time and the right ingredients to create, it is mature when the biological activity has slowed right down and it is ready to release nutrients to soil. All of the easily degraded molecules have been broken down, leaving the complex organic material behind. You should not be able to see chunks of wood or be able to see what the original material was and it should have a fine texture, dark colour, and a rich earthy smell. While a mature compost is very beneficial to plants, some of the intermediate stages may temporarily produce compounds, such as organic acids, that can be harmful to plant growth.

Immature composts,  manures and woody material continue to break down once they are incorporated into the soil. This can affect plant health by consuming or tying up two resources that growing roots need. The high level of microbial activity in unfinished compost requires a large intake of oxygen, and the microbes may pull this from the surrounding soil, essentially suffocating the roots. The high carbon to nitrogen ratio (C:N ratio) of immature compost also means that, as the carbon compounds continue to break down, microorganisms will draw on soil nitrogen to assist in the process, leaving the root zone temporarily nitrogen poor.
