Soil Organic C: N vs. Water-extractable Organic C: N
Traditionally, soil-testing laboratories have used a variety of methods to determine soil organic matter, yet they lack a practical method to predict potential N mineralization/immobilization from soil organic matter. Soils with high microbial activity may experience N immobilization (or reduced net N mineralization), and this issue remains unresolved in how to predict these conditions of net m...
متن کاملBuffer capacity andCuaffinity of soil particulate organic matter (POM) size fractions
Particulate organic matter fractions (POM), defined as sand-sized organic separates in soils, are known to be labile organic components with a rapid turnover. Recently, POM fractions were identified to be metalenriched in both metal-contaminated and uncontaminated soils. However, mechanisms for such metalenrichment are poorly understood, because of the paucity of information on the chemical pro...

متن کاملGravimetric Determination of Soil Organic Matter
Studies were carried out to evaluate a gravimetric method for the determination of soil organic matter by the mass loss at 300C. The gravimetric method was compared with Walkley-Black, using several brazilian soils with variable chemical and physical properties. Gravimetric method was positively correlated with Walkley-Black method with the following linear regression equation: y = 3.72x + 0.29...
