Open windrow composting manual

In times when mineral fertilizer is not available or too expensive, compost is the most important source to provide nutrients for the plants and to adjust the soil conditions. Today many people appreciate compost as a natural source for nutrients and humus.
To compost materials means also to close the natural circle of life. This manual tries to give a helping hand in designing and maintaining a composting plant in economically developing countries.

• It is the lowest stage for maintaining a composting plant. With this stage it is possible to produce compost in a good quality and short time.
• Mainly this Level is about a good composition for the input material by volume, monitoring the temperature and moisture, volume reduction during the composting process and the compost volume determination.

2. Advanced Level

• This Level includes all steps of the basic Level
• Additionally this Level is about the bulk density, the composition of the input material by mass, and the total mass as well as volume and mass flow during the composting process

• This Level includes the basic and advanced Level, too.
• The differences to the advanced Level are the chemical analyses. The optimization of the nutrient content and suitable nutrients ratio in the compost is the objective of this Level.
