The study involved in testing the effects of two amended organic media （loam ＋ sheep manure and loam ＋ peat moss （1：1）） and different concentrations of seaweed （sea force 2） extract including （0, 0.5, 1, 1.5 and 2 mL/L） on growth and flowering of Periwinkle （Vinca rosea） plant. The results showed that growing vinca plants in peat moss medium and spraying sea force 2 extract with low concentrations especially 0.5 mL/L resulted in positive significant difference in vegetative and flowering characteristics.展开更多

Rice hulls showed greater liming potential than rice hull biochar, while soybean and pea straws had less liming potential than their biochars. Due to their higher alkalinity, biochars from legume materials increased soil pH much compared to biochars from non-legume materials. The alkalinity of biochars was a key factor affecting their liming potential, and the greater alkalinity of biochars led to greater reductions in soil acidity. The incorporation of biochars decreased soil exchangeable acidity and increased soil exchangeable base cations and base saturation, thus improving soil fertility.展开更多
