| The information on chemistry of light fraction soil organic matter may contribute to the future nutrient and soil C management in the second-rotation plantation. | |
75 Citations | Low soil organic matter contents were mainly explained by the low amount of clay mineral-organic matter associations and limited even more by intensive agricultural practices. |
183 Citations | The data indicate that this sandy soil is highly susceptible to organic matter decomposition with cultivation. |
| Soil organic matter (SOM) content and composition may be affected by geographic region, land use (grassland vs. forest) and management intensity (intensive vs. extensive). | |
| Organic matter played a more important role in determining soil spectral signatures than the mineralogical characteristics of soils, especially in those with high organic carbon content. | |
| While organic matter quantity increases following prolonged submergence of soil; submergence also changes the chemistry and quality of soil organic matter, which influences N mineralization. | |
239 Citations | As a result, the composition of clay-associated organic matter would be influenced by the type of clay that is dominantly present in the soil. |
265 Citations | Our results suggest that for a given level of C inputs, the relationship between mineral surface area and soil organic matter varies with soil texture for physically and biochemically protected C fractions. |
| The linear regression model between color values and soil organic carbon contents showed it can be used as a rapid, cost-effective method to evaluate content of soil organic matter in Chinese tea plantations. | |
| Because soil organic matter is the most dynamic of the soil components, effects of changing soil environment are often recorded first in the quality and distribution of organic matter. | |
| The soil organic matter prediction models based on soil color have simplicity and potential to be used in the laboratory and in the field with quick and unnecessary chemical products, especially for Ultisols and Oxisols of clayey texture. | |
| This difference probably reflects the quality of soil organic matter. | |
826 Citations | Together they reflect the diverse but central effects that organic matter has on soil properties and processes. |
| Moreover, the organic matter of agricultural soil, which is most stable and has been naturally matured over a long period of time, differs substantially from the other samples. | |
220 Citations | Data presented here clearly show effects of carbon input and soil texture on equilibrium organic matter content. |
95 Citations | The results were in line with the chemical composition of soil organic matter. |
48 Citations | The results indicate that additions of organic matter from various sources differ in the effects on soil organic matter and biological activity. |
| This work demonstrates an ability to estimate topsoil organic matter content from field observations alone and provides a method by which rapid and cost-effective assessments of soil organic matter status may be made. |
