Abstract

 Spent mushroom compost (SMC) is a by-product of the mushroom industries. It is made from straw, manure, gypsum and horse-bedded straw, hay and poultry manure. SMC has been used as a SOIL AMENDMENT, particularly for intensive horticultural production. In this study the effects of various SMC's types (fresh, one year old, two years old) on changes of chemical characteristics of a loamy soil was studied for 12 weeks in a laboratory column incubation under controlled conditions. Different rates of each SMC (0, 15, 30, 60 t ha-1) were mixed with a loamy soil. The columns were leached with deionized water every week. Leachates were collected and analyzed for EC, pH, soluble cations (Sodium, Potassium, Calcium, and Magnesium), and anions (Chloride, Bicarbonate, Nitrate) content. Similar data collection was conducted on the soil samples at the beginning and at the end of the test. The results showed that EC and concentration of nutrients was the lowest in two years old SMC. It is probably due to the amount of salts leached out during the weathering of SMC. The leachate contained a higher amount of ‍‍‍Calcium and Magnesium over the 12 week period. Two years old SMC had less Cl and Na and had less effect on soil salinity and sodification. Since the slow inorganic-N release rate from SMC-amended soil is predominantly the result of the slow mineralization of recalcitrant organic-N in SMC, therefore, nitrate content in two years old SMC can provide the primary requirements of plants. Comparison of different levels of SMC showed that using 30 t ha-1 is more favorable as compared with other levels. The 60 t ha-1 level caused higher EC and salinity in the soil. As a general rule if SMC with proper aging is used at an appropriate level it can affect the chemical and physical characteristics of the soil and can be used as a SOIL AMENDMENT.
