Title: Use of Cold or Frozen Phase III Compost for Mushroom Cultivation
Author: Oscar Lahmann and Danny Rinker

Abstract:
An alternative to preparing one’s own compost for Agaricus bisporus production is to purchase the substrate from a third party. A limiting factor in the growth of Latin American mushroom production is compost preparation. Central composting facilities supplying satellite growers are rare. Production of one’s own compost is limited to the economics and scale of production. An alternative for Panama and Costa Rica has been to receive spawn-run compost from offshore. The spawn-run compost arrives by container cold or frozen and after warm up to 20°C it is cased. Production in three breaks averages 28 kg per square meter. This paper will discuss the problems, challenges, procedures, successes, failures, and economics encountered in mushroom production from cold or frozen blocks of Phase III compost.
