The ideal composition when making compost is a 30 to 1 Carbon to Nitrogen ratio (C/N). Nitrogen comes from green materials such as kraal manure, grass clippings and food scraps.Carbon comes from brown materials such as dead leaves,sawdust,wood chips and straw.
A C/N ratio of 20 indicates a slightly immature compost and one less than 20 a good compost. An older compost has a lower ratio, a very old compost is less organic and more inorganic and in turn the ash content will be higher then one needs to add in more carbon products example straw to make the compost more organic. A immature compost has a lesser value of trace elements.
A good compost should a moisture content of not less than 35-40% and not greater than 45%-50%. While composting the temperature must be greater than 60 degrees to weed seeds.
Oxygen is important when making compost, a lack of oxygen is due to too much or too little moisture and insufficient Nitrogen. When a compost heap smells it is due to anaerobic microbes and the compost heap needs to turned to aerate the compost.
The most important uses of compost are to improve the soil structure. A plant growing in a loose oxygenated soil grows much quicker than in a compact soil The nutrients are made easier available to the plants Nitrogen ,nutrients and essential trace elements added to the soil through the compost are much more economical than inorganic (artificial)granular or liquid fertlisers added.
A well composted compost makes an excellent weedfree lawndressing, it is only not suited for levelling or raising certain areas where topsoil is the suitable product.
Soils that have compost in produce healthier plants naturally no matter if its indoor plants,outdoor gardens or in vegetable patches. Mature compost soaked in water makes a “compost tea”, a nutrient rich liquid to be used with water when watering plants or as a foliar spray.

Organic Compost Gypsum Plus
Gypsum lime (calcium sulphate) has been added to our organic compost.
These are the benefits of Gypsum Lime:
- Compacted dense soils respond well to Gypsum.
- Gypsum is considered a universal soil amendment, improving aeration + water filtration into the soil.
- Gypsum prevents surface crusting of soil and conserves nitrogen.
