“…Many authors assert that the influence of earthworms contained in compost on plant growth depends on various factors, including the duration of the plant’s vegetative period. Plants with longer vegetative periods cope better with the undesirable attack of nematodes by earthworms [ 21 , 22 ].…”

Compost has a broad application in terms of the improvement of the soil properties. This research work was conducted to present the molecular implications of using compost obtained from different substrates to improve soil parameters for cucumber seedlings cultivation. In the experiment, the following compost mixtures were used: sewage sludge (80%) + sawdust (20%); sewage sludge (40%) + sawdust (10%) + biodegradable garden and park waste (50%); biodegradable garden and park waste (90%) + sawdust (10%); sewage sludge (80%) + sawdust (20%) + Eisenia fetida; sewage sludge (40%) + sawdust (10%) + biodegradable garden and park waste (50%) + Eisenia fetida; biodegradable garden and park waste (90%) + sawdust (10%) + Eisenia fetida. The final substrate compositions consisted of compost mixtures and deacidified peat(O) (pH 6.97; Corg content—55%, N content—2.3%), serving as a structural additive, in different mass ratios (mass %). The produced plants underwent biometric and physiological measurements as well as enzymatic analyses of stress markers. Based on the conducted studies, it has been found that the substrate productivity depends not only on the content of nutrient components but also on their structure, which is moderated by the proportion of peat in the substrate. The most effective and promising substrate for cucumber seedling production was variant 2 (I), which consisted of 25% compost from sewage sludge (40%) + sawdust (10%) + biodegradable garden and park waste (50%) and 75% deacidified peat. Despite the richness of the other substrates, inferior parameters of the produced seedlings were observed. The analysis of the enzymatic activity of stress markers showed that these substrates caused stress in the plants produced. The study’s results showed that this stress was caused by the presence of Eisenia fetida, which damaged the developing root system of plants in the limited volume of substrate (production containers). The adverse influence of Eisenia fetida on the plants produced could possibly be eliminated by thermal treatment of the compost, although this could lead to significant changes in composition.

The Effect of Vermicompost and Earthworms (Eisenia fetida) Application on Phytomass and Macroelement Concentration and Tetanic Ratio in Carrot

et al. 2022

This experiment evaluated the effects of various vermicompost amounts (0%, 10%, 20%, 25%, and 50%) of the total weight of the mixture of soil and vermicompost) and red worms (0, 10, and 20 individuals/pot) on carrot phytomass and macroelements concentration when applied to soil. Increasing the quantity of vermicompost (Vc) raised the weight of carrot roots and leaves. When we increased the dose of Vc, differences in phytomass growth were diminished gradually. Fifty percent of Vc in the soil did not have a negative impact on the formation of carrot roots and leaves. Vc increased the water content in roots and decreased it in leaves. Earthworms (EWs) in soil increased the weight of both carrot roots and leaves. The positive impact of EW on roots and leaves was higher when the vermicompost content in the soil was lower. EWs showed positive effects on the potassium concentration in whole carrot phytomass. Both EWs and Vc increased the value of the tetanic ratio in the carrot roots, which lowers their quality. EWs showed positive effects on the potassium concentration in whole carrot phytomass. Relationships found between K × Ca and Mg × S were antagonistic. Positive dependencies were detected between the carrot root yield and N, P, K concentration in both leaves and roots.
