Spent mushroom compost (SMC) substrates are commonly used as growth media for greenhouse crops and horticulture production. This study aimed to investigate the responses of physiochemical soil properties, enzyme activities, microbial community compositions different cultivation durations SMC treatments on tomatoes. The experiment included following treatments: substrate surrounding after planti...

Field experiment was conducted in 2008 at the Research Field of Agricultural College of Shiraz University, Shiraz, Iran to investigate the effects of urban waste compost (UWC), manure and chemical fertilizer on the initial growth of corn (Zea mays). Experimental design was split plot factorial with three replications. Main plots were assigned to nitrogen (N) fertilizer (0 and 200 kg N ha-1), an...

Application of organic amendments to soil is commonplace in domestic gardening. However, a vast array materials could be labelled as ‘compost’ by retailers and suppliers. We investigated six different currently used, or available for use, horticulture: composted bark, bracken, spent mushroom compost, horse manure, garden waste compost (at two application rates), peat. Using controlled field exp...

Establishing a simple yet reliable compost stability test is essential for a better compost quality control and utilization efficiency. The objective of this study was to examine the relationship between extractable organic carbon (OC) and compost stability based on 18 compost samples from five composting facilities. The compost samples were extracted sequentially with water for 2 h [water(2h)]...

recently, using the source of organic fertilizers and biofertilizers in sustainable crop production is growing. in order to evaluate the effect of organic compounds, biofertilizers and chemical fertilizer on morphological properties, yield and yield components of forage sorghum (sorghum bicolor) a field experiment was conducted in the research farm, college of agriculture, ferdowsi university o...

evaluation of soil microorganisms and their beneficial relationships among ecosystem components is one of new topic in soil resource management for ensuring sustainable agriculture. in order to investigating effects of trichoderma spp. and different organic manures on improvement of growth and development in soybean [glycine max (l.) merril.], an experiment was conducted at glasshouse in sari a...
