COMPOST IS A NATURAL SUBSTRATE THAT is OFTEN USED AS A SOIL IMPROVER
Compost is a product that originates form the degradatin of plant rests. The activity of micro-organisms is respondible for this degradation process. Compost consists of organic material in various fractions (humus, little twigs, etc.) and a small part mineral parts (sand, clay etc.). This process is executed in a controlled way at composting sites. The various organic materials (grass, pruning waste, leaves) are brought into the process in appropriate quantities to this purpose. The compost producer regularly turns the material around. The material is ventilated in this way, through which oxygen, moisture and temperature are optimally present. The quality of compost strongly depends on the raw materials that are used for composting.
Local production.
Compost is often used as a soil improver. By adding compost, the organic matter content stays at an appropriate level and the soil organisms are stimulated. There is compost in varied qualities by the way. In the event of application in substrates, compost is often considered a sustainable raw material. Substrate mixtures with compost require a specific basic fertilisation because the compost already contains a considerable quantity of nutrient elements.
RHP drew up extra requirements for composting in order to get a good hygienisation during the composting. As a result germs possibly present in the green waste are maximally destroyed. RHP does not allow composting all kinds of green waste, green waste from agriculture and horticulture is not allowed because they take in a bigger risk concerning plant diseases. RHP compost can be applied for many purposes because of a relatively low salt contents.
