Magnetic susceptibility in the prediction of soil attributes in two sugarcane harvesting management systems [PDF]

Engenharia Agrícola, 2013
This study aimed to investigate the potential use of magnetic susceptibility (MS) as pedotransfer function to predict soil attributes under two sugarcane harvesting management systems. For each area of 1 ha (one with green sugarcane mechanized harvesting

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 ...

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

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

Dataset for Creating Pedotransfer Functions to Estimate Organic Liquid Retention of Soils

Journal of Environmental Geography, 2014
Soil properties characterising pressure-saturation relationships (P-S), such as the fluid retention values or the fitting parameter of retention curves are basic input parameters for simulating the behaviour and transport of nonaqueous phase liquids ...
