estimation surface soil shear strength by pedo-transfer functions and soil spatial prediction functions
abstract surface soil shear strength is an effective parameter in soil erosion and runoff modeling, and known as soil erodibility index. this study was conducted to investigate and predict soil shear strength in central zagros region using multiple linear regressions (mlr). the study site was selected in rangeland and degraded-rangeland landuse with an area of 23562 ha. based on the maps of geo...
متن کاملSoil Respiration Tests as Predictors of Nitrogen Mineralization Potential
Estimation of seasonal N availability via a soil test has proved difficult. This information gap has lead to fertilizer recommendations based upon soil inorganic N levels found before planting and or preside dress. Complicating matters, as famers adopt new irrigation technologies, the results from older fertilizer rate trails may also be less applicable. In general, most when not all recommenda...

samples. When a soil analysis requires field-moist soil, a pre-incubation time of 7 to 10 d after rewetting dried Carbon and N mineralization in dried soils that are rewetted has soil may be used to equilibrate the samples before analybeen proposed as a rapid index of C and N mineralization potential sis (Franzluebbers et al., 1996). and to reflect soil management, but further research is neede...
متن کاملSoil carbon and nitrogen mineralization: Theory and models across scales
In the last 80 years, a number of mathematical models of different level of complexity have been developed to describe biogeochemical processes in soils, spanning spatial scales from few mm to thousands of km and temporal scales from hours to centuries. Most of these models are based on kinetic and stoichiometric laws that constrain elemental cycling within the soil and the nutrient and carbon ...
متن کاملSoil organic nitrogen mineralization across a global latitudinal gradient
[1] Understanding and accurately predicting the fate of carbon and nitrogen in the terrestrial biosphere remains a central goal in ecosystem science. Amino acids represent a key pool of C and N in soil, and their availability to plants and microorganisms has been implicated as a major driver in regulating ecosystem functioning. Because of potential differences in biological diversity and litter...
