Abstract—Maturity post is an important practical factor demonstrated in the case of SMC [10]. Because post
in agricultural and horticulture production. This study was techniques time-consuming and laborious, posting
conducted to perform maturity assessment for spent mushroom with anism inoculants, which can save time and
compost (SMC). Compost maturity were evaluated using reduce costs, is more popular. However, there are no reported
standard chemical analyses (pH, EC, CEC, total C and N detailed studies of posting of SMC. And few studies
+ -
content, C/N ratio, NH4 -N, NO3 -N). Subsequently, potential have addressed maturity evaluation of posting.
phytotoxicity from SMC was assessed by germination bioassay
using Lepidium sativum L. (cress). SMC samples were collected The main objectives of the current study were: (1) to obtain
periodically during a 28-d posting period from a single an overview of chemical changes taking place during
windrow. posting time, the pH and EC values posting of SMC, and (2) to determine the phytotoxicity of
a tendency to increase, and in the end, the two values maintained SMC assessed by germination bioassay at different moments
