Composting although in many ways is a natural process can sometimes lack all the necessary elements in the correct quantities to guarantee quick and efficient composting. Good compost when finished should be a complete growing medium for plants as well as a fertiliser. This means for your compost to be effective it should have all the minerals and nutrients of a very healthy soil.
Sometimes it is hard to completely control the materials that go into your compost bin and in what quantities. Home composting is a matter of household recycling. Obtaining all ingredients at the correct ratios and grading can be a challenge so adding some additives and accelerators can help the process.
One of the scarcest elements in healthy soil today is minerals historically found in rocks and sediments that make up healthy growing substrates. Some of the most fertile areas on the planet are found surrounding volcanoes or sedimentary basins of rivers and this is due to the fine amounts of rock dusts found in the soil. Composting making although high in nitrogen vary rarely contains any trace minerals which are beneficial to plant growth and soil life as a whole. There a number of rock mineral dusts and powders on the market you can add to your compost bin or pile at home.
