Effects of Quality Composts and Other Organic Amendments and Their Humic and Fulvic Acid Fractions on the Germination and Early Growth of Slickspot Peppergrass (Lepidium Papilliferum) and Switchgrass in Various Experimental Conditions
Abstract
Three representative and different composts were selected and used in this work: a green compost (GC), a mixed compost (MC) and a green coffee compost (GCC). The three composts were characterized by means of conventional methods for several chemical and physical properties, including pH, electrical conductivity (EC), moisture and ash contents, total organic carbon (TOC) content, total N content, C/N ratio and humic acid-like (HAL) content. Seeds of slickspot peppergrass were placed in Petri dishes on filter paper, and different tentative germination experiments were made. Germinated seeds were transplanted in glass pots containing fine quartz sand and Nitch nutrient solution. All the germination trials were almost unsuccessful. Correlation of the germination and seedling growth data with chemical and physico-chemical parameters of the composts, HALs and DOMs will be examined, in order to find out the parameters that influence germination and growth of peppergrass.
