developing pedotransfer functions for saline and saline-alkali soils
soil moisture retention curve is one of the soil hydraulic prosperities which its direct measurement is time consuming and expensive. therefore, indirect methods such as developing pedotransfer functions have been used to predict this characteristic from soil readily available or easily measurable data. in this study, multiple linear regression method was used to develop point pedotransfer func...
متن کاملStudy of Pedotransfer Functions Multivariate regression, MLP and RBF to estimate CEC for Soils of North Ahvaz
To estimate the Cation Exchange Capacity (CEC), indirect manner used of Pedotransfer Functions (PTFs). CEC is one of the important soil fertility factors, and not measured directly because it is costly and time consuming. Thus, used from regression equations between easily and non-easily soil properties. The purpose of this research, is develop the PTFs for CEC, with use of easily available soi...
متن کاملMacro- and Micromorphology of Subsurface Carbon in Riparian Zone Soils
Soil organic matter contains fractions that range from very active to passive, relative to microbiological activity Soil organic matter (SOM) contains fractions that range from very (Schimel et al., 1985), suggesting that classification of active to passive, relative to microbial-driven ecosystem processes and functions. A classification system is needed that can test the hypothesis SOM forms m...
متن کاملOrganic Carbon in Soils of the World
The loss of organic matter from soil is mainly the result of the clearing of forests for grassland or cropland. On the basis of the assumptions outlined here, the annual loss of organic carbon from the world's soils is between 2.5 x 1015g and 7.4 x 1015g, with 4.6 x 1015g being considered a realistic estimate. These amounts are 0.2, 0.5 and 0.3 per cent of the toial organic carbon (1477x 1015g)...
متن کاملCropping practices, soil properties, pedotransfer functions and organic carbon storage at Kuanria canal command area in India
Effects of cropping practices on soil properties viz. particle size distribution, pH, bulk density (BD), field capacity (FC, -33 kPa), permanent wilting point (PWP, -1500 kPa), available water capacity (AWC) and soil organic carbon (SOC) were assessed. The pedotransfer functions (PTFs) were developed for saturated hydraulic conductivity (Ks), water retention at FC and PWP of soils for different...
