Machine learning-based pseudo-continuous pedotransfer function for predicting soil freezing characteristic curve

Geoderma
Unfrozen water plays a crucial role in thermophysical processes occurring in frozen ground. Measurement difficulties require approximate approaches to describe the relationship between unfrozen water content (θ) and soil temperature, known as soil ...

Novel Genetic Algorithm (GA) based hybrid machine learning-pedotransfer Function (ML-PTF) for prediction of spatial pattern of saturated hydraulic conductivity

Engineering Applications of Computational Fluid Mechanics, 2022
Saturated hydraulic conductivity (Ks) is an important soil characteristic that controls water moves through the soil. On the other hand, its measurement is difficult, time-consuming, and expensive; hence Pedotransfer Functions (PTFs) are commonly used ...

Countrywide mapping and assessment of organic carbon saturation in the topsoil using machine learning-based pedotransfer function with uncertainty propagation

Catena, 2023
Stakeholders and policymakers have been becoming more and more interested not just in the potential organic carbon (SOC) saturation level of soils but also in spatially explicit information on the degree of SOC deficit, which can support future policy ...

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).

Pedotransfer function application for estimation of soil hydrophysical properties using parametric methods

Plant, Soil and Environment, 2007
Soil hydraulic properties are needed as input data to describe and simulate the transport of water and solutes in the soil profile. The most important characteristics are the soil moisture retention curve (SMRC) θ(h) and the hydraulic conductivity ...

Meteorology and geography, more than biological traits, drive variation in frog phenology across decades. [PDF]

Ecology
Abstract The fate of a species is a function of interacting environmental and biological processes. Disentangling the roles and interactions of such processes can elucidate the breadth of possible responses to global change, for instance, the potential for phenotypic plasticity or trait evolution to rescue populations from climate change.

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 ...

A simple pedotransfer function to estimate fine fraction organic carbon contents of surface horizons in French soils

Geoderma
It has been proposed to separate soil organic carbon (SOC) into two physical fractions, i.e., fine fraction organic carbon (OCfine) and coarse fraction organic carbon, to improve our ability to understand controlling factors and predict SOC contents and ...
