Collapsing gullies are among the most severe soil erosion problems in the tropical and subtropical areas of southern China. However, few studies have examined the relationship of soil particle size distribution (PSD) changes with land-use patterns in the alluvial fans of collapsing gullies. Recently, the fractal method has been applied to estimate soil structure and has proven to be an effectiv...

Abstract Soil, is a reclamable and sustainable source. it is the basis of survival and it’s implication, should be performed on the basis of productivity identification according to scientific and technical rules, we can protect this valuable source, and increase it’s productivity and usage. Nowdays, saline soils cover nearly 14.6% of the country area. Study areas (Kashan’ playa) have saline ...

Quantitative Structure-Property Relationships (QSPR) are predictive methods of macroscopic properties of substances based on their only molecular structures. If these methods were initially mainly devoted to biology and toxicology, they are nowadays increasingly used for the prediction of physico-chemical properties. In the framework of the European REACH regulation (2006), their developments a...

Urban green spaces provide ecosystem properties fundamental to the provision of ecosystem services, such as the sequestration of carbon and nutrients and serving as a reservoir for organic matter. Although, urban vegetation influences soil physico-chemical properties, it remains unknown whether ecosystem properties depend on plant species portfolios. We tested the influence of three common func...

The objective was to evaluate the effect of tannery sludge vermicompost in the chemical properties of soil cultivated with tomato and irrigated with wastewater. The experimental design was completely randomized in a factorial 6 × 2, totaling twelve treatments with three replications. The treatments were: four tannery sludge vermicompost (25% Sludge tannery(LC) + manure T1, 25% Sludge tannery(LC...

The IRS-1D LISS III false colour composite (FCC) decoded imagery belonging to Kosi river watershed of Almora district of Uttaranchal under warm humid Lesser Himalayan agro-ecological region was interpreted and surveyed for soil resource mapping. On the basis of image interpretation and ground truth study ten physiographic units were identified. Soil physiography relationship was established on ...

The analytical recovery of a mixture of polycyclic aromatic hydrocarbons (PAHs) was determined from a soil before and after oxidation with hydrogen peroxide, and subsequently treated with increasing amounts of an exogenous humic acid and subjected to different incubation periods. The release of PAHs from soil depended on the specific structure and physico-chemical properties of each PAH, and in...

Soil dehydrogenase activity is a good indicator of overall microbial activity in soil, and it can serve as a good indicator of soil condition. However, seasonal changes in soil moisture content may have an effect on soil dehydrogenase activity, making an accurate assessment of soil condition difficult. In this study, we attempted to determine the significance of soil dehydrogenase activity for ...

The Songnen Plain of the Northeast China is one of the three largest soda saline-alkali regions worldwide. To better understand soil alkalinization and salinization in this important agricultural region, it is vital to explore the distribution and variation of soil alkalinity and salinity in space and time. This study examined soil properties and identified the variables to extract soil alkalin...

The Present Study was undertaken to assess Depth Wise Studies of Physico-Chemical Properties Soil under Different Land Use System main campus university at Acharya Narendra Deva University Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during 2018-2019.
 samples were collected RWCS (Rice-Wheat cropping system), LBCS (Legume based VBCS (Vegetable System).The land use systems selected...
