Alternative organic fertilizers are being developed to minimize the adverse environmental impact of chemical plant protection agents. The interest in industrial-scale insect farming has increased in recent years. Mealworm larvae are a rich source of protein and fatty acids. This study focuses on mealworm larvae, which are characterized by a rapid increase in biomass and a high nutritional value. In the present experiment, mealworm larvae were processed into fertilizer with a high content of organic nitrogen. The fertilizer's effect on wheat growth, soil and rhizosphere microorganisms, including phytopathogenic fungi of the genus Fusarium, and N-cycle, was analyzed. Mineral nitrogen fertilizer and mealworm larvae meal used as fertilizer caused a similar increase (~40%) in the total nitrogen content of the soil. Due to its mineral content, mealworm larvae meal contributed to an increase in the concentrations of P, K, and Mg in soil. The amino acid quality was high (0.89). Increasing the load of Bacillus spp. after using the meal was negatively correlated with the Fusarium spp. load in the wheat rhizosphere. In the case of meal fertilization, ammonification was noticed, and organic nitrogen was successively mineralized. The fertilizer produced from mealworm larvae offers a viable alternative to mineral fertilizers. It improves the health and nutrient status of wheat seedlings and stimulates the growth of Bacillus bacteria that enhance the availability of soil nutrients to plants and prevent seedling damping off. Further research is needed to confirm the applicability of the mealworm fertilizer in other field crops.

用粉虫(Tenebrio molitor L.)幼虫粉施肥的普通小麦(Triticum aestivum L.)幼苗的生物特征,化学和微生物学评估

正在开发替代性有机肥料,以最大程度地减少化学植物保护剂对环境的不利影响。近年来,对工业规模昆虫养殖的兴趣增加了。细粉虫幼虫是蛋白质和脂肪酸的丰富来源。这项研究的重点是粉虫幼虫,其特征是生物量迅速增加且营养价值高。在本实验中,将粉虫幼虫加工成有机氮含量高的肥料。肥料对小麦生长,土壤和根际微生物(包括镰孢属植物致病性真菌)的影响和N循环,进行了分析。矿质氮肥和用作肥料的粉虫幼虫粉引起了土壤总氮含量的类似增加(〜40%)。由于其矿物质含量,粉虫幼虫粉促使土壤中P,K和Mg的浓度增加。氨基酸质量很高(0.89)。增加了芽孢杆菌的负荷。饭后与镰刀菌属呈负相关。小麦根际中的负荷。在粕粉施肥的情况下,注意到氨化作用,并且有机氮先后被矿化。用粉虫幼虫生产的肥料可以替代矿物肥料。它改善了小麦幼苗的健康和营养状况,并刺激了小麦的生长。芽孢杆菌细菌,可增加植物土壤养分的利用率,并防止幼苗受潮。需要进一步的研究来确认粉虫肥料在其他大田作物中的适用性。
