Fine-root trait variation in temperate trees follows arc-shape pattern along deep soil profiles. [PDF]
New PhytolRoot trait variation along the soil depth profile in four temperate tree species. Summary Roots are plants' interface with the soil, controlling access to water and nutrients. Yet, fine‐root trait variation along deep soil profiles and its functional implications remain poorly understood.

Tikrit Journal for Agricultural Sciences, 2023 There are several methods for determining the determination of soil available phosphorous. These methods require many chemicals and different devices, and determining soil available phosphorous in the laboratory is difficult, time-consuming, and costly ...

Predicting soil organic matter content using soil color at three locations with different land use in Zagreb (Croatia) [PDF]
Journal of Central European Agriculture, 2021 Soil organic matter (SOM) plays a key role in ecosystems. Reduction of its content due to land-use changes has a negative impact on the soil, but also on the wider environment. Accordingly, SOM content is routinely analyzed in the laboratory.

Uncertainty analysis for spatial prediction of soil saturated hydraulic conductivity
Shui kexue jinzhan, 2012 Pedotransfer functions are commonly used to predict soil hydraulic characteristics.However,the analysis of prediction uncertainty is often ignored by researchers.In an attempt to reduce the prediction uncertainty and to improve the applicability of ...

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

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

Retention curves of soil from the liz experimental catchment obtained by three methods
Soil and Water Research, 2009 The retention curves were measured in the soil from the Liz experimental catchment (Šumava). The sand table and pressure extractor methods were used to obtain a 13-point retention curve for undisturbed soil samples taken from 6 depths. The data points of
