Gravimetric 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...
متن کاملDetermination of Soil Aggregate Stability in Different Types and Amounts of Organic Matter in Khuzestan Plain, Iran
In soils under wheat cultivation, soil aggregates stability is increased and destructive effects of erosion decreased, due to organic matters (OM) application. This trail was conducted in Shavoor agriculture research station to determine of mean weight diameter (MWD) under different organic matter sources and amounts in Khuzestan province (at south west of Iran) via a split plot experiment base...
متن کاملSustainable Agriculture, Soil Health, and Soil Organic Matter
The latter two principles protect the soil resource on which all food and fibre production ultimately depends. However, agricultural production systems differ from ‘natural’ or undeveloped systems in that they can be considered to be ‘leaky’ with respect to nutrients. This is inevitable, due to nutrient removal in harvested product, but inappropriate fertiliser management can exacerbate the ‘le...
متن کاملSoil Organic Matter: Its Fractionation and Role in Soil Structure
An understanding of the form and function of SOM in soil is essential to sustainable crop production. Various methods of SOM fractionation are used to study SOM forms and to gain an understanding of interaction between SOM and aggregate formation. Physical SOM fractionation techniques are based on the concept that SOM associated with particles of various sizes. differs in structure and function...
متن کاملInvestigating the Effect of Soil Organic Matter on Gypsum Block Calibration for Measuring Soil Volumetric Moisture Content
Continuous soil moisture assessment and evaluation is essential for irrigation management and planning. One of the common methods for measuring the moisture content of the soil is the use of a gypsum block. The use of gypsum blocks in some cases, including the presence of organic matter in soil, may cause an error in the measurement of moisture. For this purpose, a laboratory study was conducte...
