Bulk Densities of Brazilian Amazon Soils Related to Other Soil Properties
Soil Science Society of America Journal, 1998 Abstract The results of this study provide the first baseline for predicting D b from soil properties for soils across the Amazon basin. Bulk density values are needed to convert nutrient content and organic carbon (OC) content to weight of nutrient and ...

A modified soil tilth index and its relationship with rice yield [PDF]
, 2006 This study was conducted to investigate the effect of rotary tillage on some soil physical properties (bulk density, cone index, plasticity index, aggregate uniformity coefficient) and organic matter, and to develop and evaluate a soil tilth index based ...

Saturated Soil Hydraulic Conductivity is not Constant But Varies with the Time It is Measured
Guan'gai paishui xuebao, 2021 【Background and objective】 Saturated soil hydraulic conductivity (KS) is an important parameter characterizing the ability of soil to conduct water. It is often assumed to depend on soil structure and is hence constant for a given soil.

Deriving regional pedotransfer functions to estimate soil bulk density in Austria
Die Bodenkultur, 2021 Soil bulk density is a required variable for quantifying stocks of elements in soils and is therefore instrumental for the evaluation of land-use related climate change mitigation measures. Our motivation was to derive a set of pedotransfer functions for

Predicting soil bulk density for incomplete databases
Geoderma, 2014 Abstract Soil bulk density (ρb) is important because of its direct effect on soil properties (e.g., porosity, soil moisture availability) and crop yield. Additionally, ρb measurements are needed to express soil organic carbon (SOC) and other nutrient stocks on an area basis (kg ha− 1).
