TL;DR: In this article, a review of the existing PTFs and new generation of PTF developed in the different disciplines of Earth system science is presented, emphasizing that PTF development has to go hand in hand with suitable extrapolation and upscaling techniques such that the PTF models correctly represent the spatial heterogeneity of soils.

Weighted recalibration of the Rosetta pedotransfer model with improved estimates of hydraulic parameter distributions and summary statistics (Rosetta3)
Yonggen Zhang,Marcel G. Schaap +1 more
TL;DR: In this paper, an improved set of hierarchical pedotransfer functions (Rosetta3) is presented, which unifies the water retention and K s submodels into one.
Journal ArticleDOI
Estimation of Saturated Hydraulic Conductivity with Pedotransfer Functions: A Review
TL;DR: In this paper, the authors discuss the history of the development of the concept of saturated hydraulic conductivity and its relation to the Kozeny-Carman (KC) equation.
Journal ArticleDOI
A High‐Resolution Global Map of Soil Hydraulic Properties Produced by a Hierarchical Parameterization of a Physically Based Water Retention Model

Enzymatic Hydrolysis of Corn Stover after Pretreatment with Dilute Sulfuric Acid
TL;DR: In this article, the authors evaluated the influence of five factors and their interactions on enzyme hydrolysis of corn stover in pretreatment with dilute sulfuric acid and showed that the optimal levels for each variable to obtain the highest reducing sugar yield were as follows: enzyme concentration of 22 FPU/g substrate, substrate concentration of 77 g/L, temperature of 49°C, pH 4.8 and reaction time of 38 h.
