EFFECT OF VERMICOMPOST FROM POPLAR LEAF WASTE ON ROOT FORMATION IN WHEAT SEEDS
Abstract
We have determined that the vermicompost obtained from processing poplar leaf waste by the culture Eisenia fetida Savigny has peculiar agrochemical properties. The vermicompost obtained from processing horse manure had the average contents of K+ and NO3 - of 112.2 and 82.8 milliequivalent/ kg of dry weight, respectively. It was significantly higher than the analogous parameters of vermicompost obtained from poplar leaf waste (73.0 and 5.6 milliequivalent/kg of dry weight, respectively). The PH values and concentration of calcium ions in the vermicompost from poplar leaf waste were significantly higher than those in the vermicompost from horse manure (7.61 vs 6.98, and 112.3 vs 83.0 milliequivalent/kg of dry weight, respectively). The sprouting of wheat seeds on poplar-leaf-based vermicompost extracts resulted in a significant increase in the relative weight of the roots as compared with the seeds grown on tap water. We did not observe such an effect in the case of vermicompost from horse manure.
