Different machine learning algorithms were assessed for estimating five functional soil parameters (SOC content, Calcium content, Phosphorous content, sand content, and pH value). The algorithms used include variants of linear regression and support vector regression. A closer look at the prediction performance for each target revealed that apart from pH, which consistently had worse performanc...

Plant-soil interactions can strongly influence root growth in plants. There is now increasing evidence that root-root interactions can also influence root growth, affecting architecture and root traits such as lateral root formation. Both when species grow alone or in interaction with others, root systems are in turn affected by as well as affect rhizosphere pH. Changes in soil pH have knock-on...

High residues of DDT in agricultural soils are of concern because they present serious threats to food security and human health. This article focuses on remediation of DDT-contaminated soil using laccase under different soil oxygen and soil pH conditions. The laboratory experiment results showed significant effects of soil oxygen conditions and soil pH on remediation of DDT-contaminated soil b...

The objective of this study was to evaluate effects of elemental sulfur (S) addition on soil pH and availability of macroand micronutrients during the sugarcane growing season. Sulfur application did not significantly reduce soil pH when applied at 0 to 448 kg S ha−1 due to the high soil buffering capacity. Water extractable phosphorus (P) and potassium (K) for soils receiving the highest S rat...

The high iron content in the soils and resident parent material of the Georgia Piedmont results in significant transport of iron in runoff to receiving waterbodies. Phosphorus cycling in lakes can be significantly affected by the iron cycle. The work presented here describes experiments to test sorption and desorption of phosphate from Bt horizon soil to help illuminate the role of transported ...

UNLABELLED Accumulating empirical evidence over the last 60 years has shown that the reduction of N2O to N2 is impaired by low soil pH, suggesting that liming of acid soils may reduce N2O emissions. This option has not gained much momentum in global change research, however, possibly due to limited understanding of why low pH interferes with N2O reductase. We hypothesized that the reason is tha...

Prescribed burning is a common management tool used in grassland restorations to improve conditions for plant growth. At a grassland restoration in Maryland, we studied the impacts of sequential prescribed burning on near-surface soil chemistry of a highly weathered soil. We hypothesized that soil pH and base cations in the surface soil would increase in the nutrient-poor soils after the burnin...

Acidification and pollution are two major threats to agricultural ecosystems; however, microbial community responses to co-existed soil acidification and pollution remain less explored. In this study, arable soils of broad pH (4.26-8.43) and polycyclic aromatic hydrocarbon (PAH) gradients (0.18-20.68 mg kg-1) were collected from vegetable farmlands. Bacterial community characteristics including...

This study was undertaken with the aim of illuminating the soil-plant interactions of Pistacia lentiscus L., which is a Mediterranean sclerophylleous coastal zone plant in the Western Anatolian part of Turkey. The soil analysis data showed that this plant grows on different kinds of soils such as sandy-clayey-loam, clayey-loam, sandy-loam and loamy texture. Soils are not saline, with pH moderat...

This project was undertaken to study the biodegradability of PLA-KF biocomposite in different conditions; soil burial and immersion in water. The samples were buried in soil for 40 days to investigate the degradability of biocomposites. As for water absorption tests, the samples were immersed in three different types of water which were river water (pH 6), tap water (pH 7) and sea water (pH 7.5...
