Abstract:

If all the facts were recorded, they would undoubtedly show that every commercial mushroom grower and nearly every research worker concerned with mushrooms have conducted casing soil tests in an effort to improve yield. Results from a very small percentage of these tests have been reported, and the search continues for the “best” casing medium with a tremendous duplication of effort. This situation will no doubt continue, with little real progress being made, until someone is successful in describing precisely what attributes of the casing layer are important and how they function in the process of sporophore initiation and maturation.

It is generally assumed that certain chemical and physical properties of the casing layer are important factors in mushroom production. Structure and moisture holding properties are perhaps the primary physical factors influencing yield, and pH the most critical of the chemical factors (1, 2, 6, 7, 8, 10). Casing soil-cropping experiments concerned with a comparison of soil types, mineral versus peat and muck soils, and casing soil additives both physical and chemical have been reported by several investigators (3, 5, 9, 11, 12, 13,14). The purpose of this paper is to record results of casing soil experiments conducted at West Chicago, Illinois.
