Verification of Appropriateness of Selected Pedotransfer Functions for the Basic Use in Agriculture of the Czech Republic

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2015
Soil is a huge reservoir of water used by plants in periods without precipitation and significantly affects the hydrological balance of any territory. To evaluate the hydrological balance of any piece of the land given, it is therefore necessary to carry

Pedotransfer functions of soil water properties to estimate the S-index

Revista Brasileira de Engenharia Agrícola e Ambiental
One big challenge for soil science is to translate existing data into data that is needed. Pedotransfer functions have been proposed for this purpose and they can be point or parametric when estimating the water retention characteristics. Many indicators

Biological Salt‐Pump Effect: Long‐Term Stand Development of Haloxylon ammodendron and Its Role in Reshaping Soil Hydrothermal and Salinity Regimes

Land Degradation &Development, EarlyView.
ABSTRACT Afforestation in the desert–oasis ecotone induces soil desiccation and secondary salinization. However, the seasonal dynamics of soil water–heat–salt interactions across plantations of different stand ages in arid regions remain unclear. Here, we investigated the seasonal patterns and coupled relationships of soil water–heat–salt dynamics in ...

Estimation of the Retention and Availability of Water in Soils of the State of Santa Catarina

Revista Brasileira de Ciência do Solo, 2018
: Soil water retention and availability are important properties for agricultural production, which can be measured directly or estimated by pedotransfer functions. Some studies on this topic were carried out in Santa Catarina, Brazil.

Ditch‐Buried Straw Return Improves Soil Physical Quality and Crop Biomass in Two Rice–Wheat Paddy Soil Systems

Land Degradation &Development, EarlyView.
ABSTRACT Ditch‐buried straw return (DB) is an innovative practice combining deep tillage and straw incorporation. This study aimed to evaluate its effects on soil physical quality compared to rotary tillage (RT) and identified key constraints to crop in sandy‐loam and clay‐loam paddy soils within rice–wheat systems. Two field experiments were conducted

Determining the Optimal Water Storage Depth of Apple Orchards in the Chinese Loess Plateau: Balancing Soil Desiccation Mitigation, Plant Utilization, and Engineering Construction

Land Degradation &Development, EarlyView.
ABSTRACT Deep‐rooted plantations are central to dryland ecological restoration, yet their long‐term cultivation drives widespread deep soil desiccation, threatening ecosystem sustainability. While artificial water replenishment is a key deep soil desiccation mitigation strategy, the depth‐dependent positional effect of stored water on eco‐hydrological ...

Comparison of pedotransfer functions for the determination of saturated hydraulic conductivity coefficient

Environmental Protection and Natural Resources, 2017
On one hand, direct methods of measurement of saturated hydraulic conductivity coefficient are time consuming, and on the other hand, laboratory methods are cost consuming. That is why the popularity of empirical methods has increased.

A framework to evaluate and identify development requirements for land‐surface models at km‐scale resolution: Application to a semi‐arid and mountainous region

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This article provides a first evaluation of land‐surface models at the km‐scale resolutions at which they are used in weather and Earth‐system models. At these resolutions, the lateral transfers of water that organize landscapes play an important role in predicting evaporation correctly. Riparian processes and human water management for irrigation need

Using of pedotransfer functions for assessment of hydrolimits

Plant, Soil and Environment, 2002
Soil hydrologic coefficients, also called hydrolimits, are soil water contents defined for certain values of water potentials. Closer attention is paid to three hydrolimits: field capacity, point of decreased availability, and wilting point.
