Soil type and land use impact on carbon levels in agriculture.
Soil microorganisms are important for ecosystem health. A study in Shandong Province looked at how different types of soil and land use affect microbial biomass carbon (MBC). They found that MBC levels were highest in crop lands, followed by vegetable lands and then forest lands. MBC was also influenced by soil type, with the impact of land use patterns being more significant. MBC was positively correlated with total nitrogen and organic matter, but negatively correlated with available phosphorus. Returning straw to fields and using organic fertilizer can help increase MBC in soil.
