متن کاملThe Effect of Different Soil Amendments on Growth of Mung bean (Vigna Radiata L.) in Coal Mine Overburden Dumps
The surface mining activities in the past and in recent times has resulted into existence of number of overburden dumps through excavation and depositing removed soil and rock debris. These dumps require environmental stabilization/restoration, through proper revegetation. To achieve this aim, a study was conducted to find the efficacy of Mung bean (Vigna radiata L.), an economically important ...
متن کاملEffects of Nutrient Enrichment on the Producer Trophic Level of a Six-Year Old-Field Community
The effects of nutrient enrichment (i.e., application of sewage sludge and fertilizer) on a 6-yearold-field community were investigated. Vegetation was harvested in eight 0.1-ha plots comprising three treatments. Three plots were treated five times annually (May-September) with sludge; three plots were treated with an equivalent nutrient subsidy of urea-phosphate fertilizer; and two plots were ...
