| The problem of finding environmentally friendly organic fertilizers is obvious. The aim of the work was to determine safe doses of Hermetia illucens L. zoohumus application to low fertility soil. A field experiment was conducted on plots of 1 m2. Zoohumus was applied to the soil in doses of 0.5, 1, 1.5, 2, 3 kg/m2. The field germination of Triticum aestivum L. wheat, the growth of its aboveground parts on the 14th day and 117th day of the experiment were determined, and also conducted bioassays on the chemotaxis of Paramecium caudatum Ehrenberg and bioluminescence of Escherichia coli Migula. On the 14th day of the experiment the germination of T. aestivum was reduced (by 56-77% compared to the control, r = -0.72). However, on the 117th day of the experiment, an increase in the number of shoots and their length compared to the control was shown, the maximum being for the variants of 0.5-1.5 kg/m2 of zoohumus (p<0.05). Bioassays made it possible to clarify the optimal doses of zoohumus application to the soil. Safe options for soil fertilization were additives of zoohumus from 0.5 to 1.0 kg/m2. Thus, the effectiveness of H. illucens zoohumus as an organic fertilizer was confirmed and it was proven for the first time that the soil does not change toxicological indicators when optimal dosages are observed. | ||
