The present work is an extension of earlier research [Leggo, P. (2000) An investigation of plant growth in an organo-zeolitic substrate and its ecological significance. Plant and Soil, 219: 135-146.] in which zeolitic tuffaceous rock containing clinoptilolite, a commonly occurring natural zeolite mineral, was composted with organic waste to produce a very(More)
This work concerns a series of experiments designed to test and understand the effect of ammoniated zeolite on plant growth. The affinity of the zeolite mineral clinoptilolite for NH4 + is utilised in organo-zeolitic substrates to enhance plant growth. By comparing plants grown in substrates with and without ammoniated zeolite, an increase in plant dry(More)
