Abstract

SUMMARY Greenwaste mulches affect avocado tree growth and roots through small incremental changes in phenology and the soil from mulch to mulch. Trees growing under greenwaste mulches had a tendency for greater trunk growth, more roots, and an increase in some minerals and for more earthworms in the soil than the minimal mulch, leaf litter and post peelings mulches. The greenwaste mulches had considerable quantities of nutrients and may act as slow release fertilizers. The mulches evaluated did not prevent or slow down the drying of soil and cannot be considered as a substitute for irrigation. We believe mulches made from greenwaste make suitable mulches for avocado trees.
