Incorporating Auxiliary Data of Different Spatial Scales for Spatial Prediction of Soil Nitrogen Using Robust Residual Cokriging (RRCoK)

open access: yesAgronomy, 2021
Auxiliary data has usually been incorporated into geostatistics for high-accuracy spatial prediction. Due to the different spatial scales, category and point auxiliary data have rarely been incorporated into prediction models together.

Predicting Soil Salt Content Over Partially Vegetated Surfaces Using Non-Negative Matrix Factorization

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2015
Remote sensing has been widely applied to map soil salinity in the last few decades. However, a notable decrease in the accuracy of soil salt content (SSC) predictions occurred when the soil surfaces were partially vegetated. To minimize the influence of

Ecological and human health risk assessment of heavy metals based on their source apportionment in cropland soils around an e-waste dismantling site, Southeast China

open access: yesEcotoxicology and Environmental Safety, 2022
An accurate understanding of soil heavy metal (HM) pollution characteristics and source apportionment, and a recognition of the major factors influencing ecological and human health risks (HHRs) are essential for soil HM pollution control and remediation.

Wien effect of Cd/Zn on soil clay fraction and their interaction

open access: yesGeochemical Transactions, 2018
Background The coexistence of Cd2+ and Zn2+ ions in nature has a significant influence on their environmental behaviors in soils and bioavailability for plants. While many studies have been done on the mutual toxicity of Cd2+ and Zn2+, few studies can be

Lead adsorption by biochar under the elevated competition of cadmium and aluminum

open access: yesScientific Reports, 2017
Competitive adsorption studies are important to accurately estimate the lead adsorption capacity on biochar in soil. The structure of biochars was evaluated by Fourier-Transform Infrared Spectroscopy and X-ray Diffraction, and the competitive of Cadmium (

Characteristics and Mechanisms of Soil Co-Contamination Affecting the Transfer of Cadmium and Arsenic in Peanut (Arachis hypogaea L.)

open access: yesAgronomy, 2023
Soil co-contamination with cadmium (Cd) and arsenic (As) occurs frequently and has caused increasing concern. This study aimed to explore the transfer characteristics and the chemical forms, subcellular distribution of Cd and As, as well as the synthesis

Nanomaterials as Soil Pollutants

open access: yes, 2018
This chapter covers how engineered nanomaterials (ENMs) may enter soils, how they behave in soils, the exposure dynamics this presents to soil organisms, and resulting issues for uptake and food-chain transfer. Special attention is given to summarizing the main issues and the current state of the art for the most important elements of how ENMs act as ...
