| Abstract:
Studies were made of the use of slurry produced by methanogenic fermentation of cow manure, as a growth medium for horticultural crops. Various applications were suggested and proved to be beneficial. The dried slurry was tested as a component in gravel culture of roses. Forage crops grown on partially washed slurry produced high yields. Sieved and leached slurry ("cabutz") was tested as a peat substitute in rooting and growth media, and in most cases proved to be a good substitute. The rooting activity of an aqueous extract from cabutz and that of humic acid fractions of cabutz and sphagnum peat was tested. | |
