“…Studies have documented changes in the behavior of various insect taxa following biochar incorporation into soils. For instance, increased activity levels and alterations in movement patterns among decomposer organisms like earthworms or springtails have been observed [46]. These changes are often linked to biochar-induced modifications in soil properties, such as enhanced soil moisture retention, improved nutrient availability, or changes in microhabitat conditions.…”

Biochar, a carbonaceous material produced through pyrolysis of organic matter, has garnered attention for its potential to enhance soil fertility, structure, and overall health. However, its effects on soil-dwelling insects remain a subject of considerable interest and debate. This chapter critically examines the current state of knowledge regarding the interactions between biochar applications and soil-dwelling insects, encompassing diverse aspects such as alterations in insect community composition, population dynamics, behavioral changes, and potential mitigation of infestations. Through an exploration of empirical studies and theoretical frameworks, it aims to elucidate the intricate relationships between biochar amendments and soil insect ecology.

“…La aplicación de biocarbón junto con dosis fijas de óxido de silicio, nitrato de potasio y fósforo en dosis mínimas puede mejorar el desarrollo de un cultivar de banano (planta madre y el hijo de sucesión) y tener un efecto sinérgico en el crecimiento y desarrollo del banano. Por otra parte, La combinación de biocarbón con silicio no solo minimiza la formación de compuestos nocivos, como la cristobalita (Ratnadass et al, 2024), sino que también desempeña un papel crucial en la mitigación de la toxicidad del cadmio (Cd), según lo indicado por Tan et al (2024). Con lo expuesto, el objetivo de investigación fue medir el efecto de varios tratamientos de biocarbón más dosis fija de óxido de silicio, nitrato de potasio y fósforo en el desarrollo de plantas de banano.…”

Bananas have high nutrient needs, and farmers rely on chemical fertilizers that damage the soil. One of the solutions is the combination of organic fertilizers with chemical fertilizers in smaller amounts. In this context, the objective was to measure the development of a banana cultivar in different treatments of biochar plus fixed doses of SiO2, KNO3 and P2O5. Biochar (BC) was obtained from banana rhizomes at a temperature of 350 °C for 2 hours. In the experiment, 10 plants per treatment were evaluated, consisting of doses per plant of 100 g BC + 100 g SiO2, 20 g BC + 100 g SiO2 and 100 g SiO2 (control plot). These doses were applied in weeks one, eight and 16 of the experiment. The fertilizer dose for all treatments was 75 kg ha-1 KNO3 + 50 kg ha-1 P2O5, and which were applied 15 days prior to the biocarbon dose and during the sixth week of the experiment. The study showed that the 20 g biochar treatment was the most effective in terms of plant height and pseudostem circumference, surpassing the 100 g treatment and the control. The 100g biochar treatment also had the highest bunch weight compared to other treatments. In general, the biochar, silicon, and fertilizer treatments improved the physiological performance of the plants, suggesting their potential application in agriculture.

Background and aims Biochar is a carbon source employed to improve soil properties, promoting plant health and nutrition in agroecosystems. Root associated microorganisms such as arbuscular mycorrhizal fungi (AMF) are also used as bioinoculants in combination with biochar to provide eco-friendly alternatives for crop production under unfavorable growth conditions. However, information on the effects of biochar on multitrophic interactions of plants with herbivorous insects is limited. Therefore, the objective of this work was to evaluate the effect of biochar and arbuscular mycorrhizae on plants and herbivorous insects. Methods We established a multifactorial experiment with maize plants, AMF (two strains, Rizhophagus irregularis and a native consortium) and the Fall Armyworm Spodoptera frugiperda with and without soil application of biochar. Variables of biomass, plant nutrition, mycorrhizal colonization and performance of herbivorous insects were measured. Results We found that biochar reduced insect herbivory and promoted mycorrhizal association in maize. However, plant growth was reduced. Additionally, AMF increased the weight of fall armyworm larvae. Conclusion Our results show that biochar influences maize plant development, AMF, and fall armyworm performance, but did not affect interactions between these below- and above ground components.
