Delayed Release Nutrient Supplement for Mushroom Culture

Abstract

The disadvantages associated with the supplementation of noncomposted nutrients to mushroom compost at spawning were largely overcome by encapsulating microdroplets of vegetable oil within a protein coat that was denatured with formaldehyde. Increases in mushroom yield of 60% were obtained. Delayed nutrient release was indicated by prolonged stimulation of yields beyond the first few flushes.
