What nutrients in soil enhance microbial carbon build?
Best insight from top research papers
Nitrogen (N) and phosphorus (P) are crucial nutrients in soil that enhance microbial carbon build. Research indicates that the addition of N and P influences microbial physiology, leading to increased microbial growth and carbon use efficiency (CUE). Moreover, the interaction of crop residue with supplementary nutrients like N, P, and sulfur influences microbial biomass carbon (MBC) and microbial use efficiency, ultimately affecting soil organic matter (SOM) formation. Additionally, the availability of N, P, and potassium (K) impacts soil carbon cycling by influencing microbial stoichiometric constraints to growth and respiration, with labile organic matter further mediating the response to nutrient additions. Overall, N and P play significant roles in enhancing microbial carbon build and influencing soil carbon dynamics.

How biochar can increase soil carbon?5 answersBiochar can increase soil carbon through several mechanisms. Firstly, biochar application rates have been shown to gradually increase soil organic carbon (SOC) levels over time. Higher biochar application rates result in higher SOC levels, indicating a positive effect of biochar for carbon stabilization. Additionally, biochar can enhance the activities of soil enzymes involved in carbon cycling, such as β-D-glucosidase, cellobiohydrolase, and β-N-acetylglucosaminidase. These enzyme activities are positively correlated with the soil carbon pool management index (CPMI), which is a measure of carbon stabilization. Furthermore, biochar can influence the composition of bacterial communities in the soil, favoring oligotrophic bacteria that are more conducive to carbon sequestration. Overall, increasing biochar application rates and time can enhance soil carbon stabilization by reducing labile organic carbon proportions and promoting enzyme activities and bacterial communities that facilitate carbon sequestration.
How compost increases soil organic carbon?5 answersCompost increases soil organic carbon through several mechanisms. Firstly, the addition of compost directly fertilizes the soil with carbon, increasing soil carbon content. Secondly, compost stimulates plant productivity, leading to increased plant-derived carbon inputs into the soil. Thirdly, compost application enhances soil microbial biomass and activity, which promotes the formation and maintenance of soil aggregates. These aggregates provide physical protection to organic matter, preventing its decomposition and increasing soil carbon storage. Additionally, compost inputs introduce stable humic substances into the soil, which can bind and stabilize labile organic carbon compounds, further contributing to soil carbon accumulation. Overall, the combination of direct carbon input, increased plant productivity, enhanced microbial activity, and the formation of stable soil aggregates all contribute to the increase in soil organic carbon with compost application.
What are the effects of potassium on the microbiome of disturbed soil?5 answersPotassium has significant effects on the microbiome of disturbed soil. Addition of potassium mineral stressed compost increased the soluble potassium in the soil and led to changes in the microbial consortia and community composition. Disturbances such as clearcut logging, salvage logging, and fires also altered the diversity and composition of soil microbial communities, including ectomycorrhizal fungi, archaea, and bacteria. Furthermore, the addition of potassium fulvic acid (BSFA) and potassium humate (KHM) as organic fertilizers increased soil pH, nutrient content, and microbial function, while reshaping the microbial community structure. These changes in the microbiome can have implications for nutrient cycling, soil health, and plant diseases.
