%X One hundred Swiss composts and digestates were investigated in order to evaluate  their influence on plant growth and health. Important differences in biological compost  quality and on the impact on soil fertility and on plant health were observed. The most  important limiting factor of compost quality is the possible immobilization of  mineralized nitrogen by some composts. However, quality composts have a good  potential to protect plants against diseases. More attention should be paid to the  control of the composting process in order to improve the biological quality of  composts with more beneficial effects on crops.
