Whilst we recommend our KPS Fine Compost product for most soil conditioning applications, some customers have used Mushroom Compost for many years and prefer to stick to what they know. Mushroom Compost has a high organic matter content, making it an ideal product for soil improvement and mulching. It is also particularly suitable for growing most vegetables.
Mushroom compost is slightly more alkaline than our Fine Compost. It is therefore most useful on acid soils that are low in organic matter, where the liming effect is an added benefit to soil fertility. Mushroom compost is not recommended for neutral, alkaline or chalky soils, which would be made excessively alkaline by the addition of further chalk.
