What is soil organic matter?5 answersSoil organic matter refers to all organic carbon-containing substances in the soil, ranging from relatively undecomposed plant litter and microbial remains to highly polymerized, stable products of degradation and synthesis. It includes plant and animal residues at various stages of decomposition, such as fresh undecomposed materials, partially decomposed products, and well-decomposed humus. Soil organic matter is composed of carbon and other elements and is a dynamic component of the soil, with inputs from plant detritus and processing by microorganisms. It plays a crucial role in many soil functions and ecosystem services, such as providing food for microorganisms, storing nutrients, retaining water, acting as mulch, and improving soil structure and fertility. Soil organic matter also contributes significantly to the sequestration of carbon.
How can soil organic carbon be estimated?5 answersSoil organic carbon can be estimated using various methods. One approach is to collect soil samples and analyze them in a laboratory. Another method involves in-situ assessment using the soil combustion method, where a metal tube with a heating probe is used to heat the soil and measure the accumulated CO2 concentration to estimate soil organic carbon. Additionally, modeling cause-and-effect relationships among soil processes can improve the generalizability of prediction models for soil organic carbon estimation. Geostatistical methods such as kriging combined with land use, ordinary kriging, inverse distance weighting, and radial basis function can also be used to predict the spatial distribution patterns of soil organic carbon content and density. These methods provide valuable insights into soil composition and are essential for ecological studies, climate change research, and agricultural productivity.
