Predicting and delineating soil temperature regimes of China using pedotransfer function
Journal of Integrative Agriculture, 2023 Soil temperature regime (STR) is important for soil classification and land use. Generally, STR is delineated by estimating the mean annual soil temperature at a depth of 50 cm (MAST50) according to the Chinese Soil Taxonomy (CST).

An Improved Pedotransfer Function for Soil Hydrological Properties in New Zealand
Applied SciencesThis paper describes a new pedotransfer function (PTF) for the soil water content of New Zealand soils at seven specific tensions (0, −5, −10, −20, −40, −100, −1500 kPa) using explanatory variables derived from the S-map soil mapping system.

Using data assimilation to optimize pedotransfer functions using field-scale in situ soil moisture observations [PDF]
Hydrology and Earth System Sciences, 2021 Soil moisture predictions from land surface models are important in hydrological, ecological, and meteorological applications. In recent years, the availability of wide-area soil moisture measurements has increased, but few studies have combined model ...

Remaining phosphorus estimated by pedotransfer function
Revista Brasileira de Ciência do Solo, 2011 Although the determination of remaining phosphorus (Prem) is simple, accurate values could also be estimated with a pedotransfer function (PTF) aiming at the additional use of soil analysis data and/or Prem replacement by an even simpler determination ...

Controls on Saturated Hydraulic Conductivity in a Degrading Permafrost Peatland Complex
Water Resources Research, 2023 Permafrost peatlands are vulnerable to rapid structural changes under climatic warming, including vertical collapse. Peatland water budgets, and therefore peat hydraulic properties, are important determinants of vegetation and carbon fluxes. Measurements
