Moisture and Ash in Soils
Testing for total carbon and nitrogen in arable soils can provide valuable information regarding fertilization needs that can be used to make fertilization management decisions for the soil. Carbon content in soils can represent the presence of organic matter and is used to estimate nitrogen availability from natural decay. Nitrogen is one of the most important elements for plant development and is the one most often found to be deficient in arable soils. While carbon in almost any form is a benefit to the soil, the benefits are heightened with the right ratio of nitrogen.
Total organic carbon (TOC) determination in soil is a common and important analytical tool because TOC content can directly affect plant growth. It works as both a source of energy and a trigger for nutrient availability through mineralization.
Total organic carbon (TOC) determination in soil is a common and important analytical tool because TOC content can directly affect plant growth. It works as both a source of energy and a trigger for nutrient availability through mineralization. The temperature-dependent method requires minimal sample pretreatment and no acidification, removing hazardous chemicals and time-consuming acid digestions from the process.
Soil water content plays an important role in groundwater recharge and soil chemistry. The amount of moisture or soil water is important as it serves as a solvent and carrier of food nutrients for plant growth, allows microorganisms to perform metabolic activities important for releasing nutrients in the soil, and regulates soil temperature. Additionally, the determination of a variety of analytically important constituents within soil (carbon, nitrogen, sulfur, etc.) requires moisture correction utilizing an accurate moisture value. Ash determination can be utilized to calculate the organic matter content of soils.
