Soil nutrients are essential factors that reflect farmland quality. Nitrogen, phosphorus, and potassium elements for plants, while silicon is considered a “quasi-essential” element. This study investigated the spatial distribution of plant in soil hilly region Pearl River Delta China. A total 201 samples were collected from topsoil (0–20 cm) analysis nitrogen (TN), available phosphorus (AP), (A...

BACKGROUND Soil organic carbon (SOC) represents a significant pool of carbon within the biosphere. Climatic shifts in temperature and precipitation have a major influence on the decomposition and amount of SOC stored within an ecosystem and that released into the atmosphere. We have linked net primary production (NPP) algorithms, which include the impact of enhanced atmospheric CO2 on plant gro...

The hill tribes in Thailand traditionally depend on rotational shifting cultivation (RSC). However, insufficient understanding remains post-fire soil properties and erodibility ( k -values) with fallow years. To address this gap, the levels of organic carbon (SOC), total nitrogen (STN), nutrients, after fire RSC were investigated. Topsoil (0–10 cm) samples from sites 4 (RSC-4Y), 5 (RSC-5Y), 7 (...

Exponential industrialization and rapid urbanization have resulted in contamination of soil by metals from anthropogenic sources in Dongguan, China. The aims of this research were to determine the concentration and distribution of various metals (arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb) and zinc (Zn)) in soils and identify their potential heal...

Pesticide residues and heavy metal concentrations were determined in two depths (0–20 20–40 cm) of Chromic Cambisol 69 vineyards the Slovenian winegrowing region Karst. Similarly, pesticide also Calcaric 11 other Croatian regions Istria. The topsoil was analysed for presence 176 different pesticidal active substances using multiresidue analytical methods: (a) gas chromatography coupled with mas...

BACKGROUND Anthrax, a global re-emerging zoonotic disease in recent years is enzootic in mainland China. Despite its significance to the public health, spatiotemporal distributions of the disease in human and livestock and its potential driving factors remain poorly understood. METHODOLOGY/PRINCIPAL FINDINGS Using the national surveillance data of human and livestock anthrax from 2005 to 2013...

In a multi-strata agroforestry system in the central Amazon near Manaus, we studied the root activity distribution of different fruit trees and a legume cover crop in comparison to monocultures and a secondary forest site. Uptake of applied P, P and N from 0.1, 0.6 and 1.5 m depth was compared in both the dry and wet season. The results obtained with P were similar to those with N but showed a ...

Analyzing the dynamics of soil particle-size distributions (PSDs), soil nutrients, and erodibility are very important for understanding the changes of soil structure and quality after long-term land-use conversion. We applied multifractal Rényi spectra (Dq) and singularity spectra (f(α)) to characterize PSDs 35 years after conversions from cropland to shrubland with Caragana microphylla (shrubl...

The Airborne Hyperspectral Scanner (AHS) and the Hyperion satellite hyperspectral sensors were evaluated for their ability to predict topsoil organic carbon (C) in burned mountain areas of northwestern Spain slightly covered by heather vegetation. Predictive models that estimated total organic C (TOC) and oxidizable organic C (OC) content were calibrated using two datasets: a ground observation...
