Biochar and mycorrhiza are two crucial components that can significantly impact soybean growth and nutrient absorption.
Research has shown that the combination of mycorrhiza and biochar has a more potent effect on increasing the absorption of elemental nutrients in plants compared to using either of them alone (Giono et al., 2021). Biochar, as an organic soil amendment, plays a crucial role in improving soil quality by enhancing nutrient retention and absorption (Liu et al., 2022). Additionally, biochar application has been reported to promote crop biomass accumulation, growth, development, and grain yield, indicating its positive impact on plant productivity (Liu et al., 2020).
In the context of soybean cultivation, studies have demonstrated that biochar can regulate soil properties and root growth, thereby influencing soybean yield (Wu et al., 2022). Furthermore, the application of biochar in combination with mycorrhizae has been shown to enhance plant growth, root parameters, chlorophyll content, and nitrogen content in soybean, particularly under water stress conditions (Jabborova et al., 2022). This highlights the synergistic effects of biochar and mycorrhizae in promoting plant health and performance.
Moreover, the interaction of biochar with environmental conditions is crucial in determining its effects on plant growth. For instance, biochar amendment can modify gene expression in soybean and affect the severity of diseases like Rhizoctonia foliar blight (Copley et al., 2017). Additionally, biochar application, along with nitrogen and phosphorus, has been found to enhance the symbiotic performance, growth, and nutrient uptake of soybean (Egamberdieva et al., 2021).
The combination of biochar and mycorrhiza holds great potential in improving soybean growth, nutrient absorption, and overall crop productivity. By understanding the synergies between these soil amendments and beneficial microorganisms, farmers can optimize agricultural practices to enhance sustainability and yield in soybean production.
