Mulch total - Der Garten der Zukunft
KRETSCHMANN, Kurt and Rudolf BEHM
Long time gardener Kurt Kretschmann has focused his experiments on mulching techniques. He uses exclusively plants-based mulches for his fertilization. Among his observations are increased soil activity (i.e. earthworms), and better water retention. The book also includes wise observations and scientific analysis from chemist Rudolf Behm.
