The Cone Penetration Test (CPT) is a common in-situ test which generally investigates a much greater volume of soil more quickly than possible from sampling and laboratory tests. Therefore, it has the potential to realize both cost savings and assessment of soil properties rapidly and continuously. The principle objective of this paper is to demonstrate the feasibility and efficiency of using a...

introduction: saffron is one of the most important economic plants in the khorasan province. awareness of soil quality in agricultural lands is essential for the best management of lands and for obtaining maximum economic benefit. in general, plant growth is a function of environmental factors especially chemical and physical properties of soil (20). it has been demonstrated that there was a po...

Evaluation of soil quality can be crucial for designing efficient farming systems and ensuring sustainable agriculture. The present study aimed at evaluating the quality of waterlogged purple paddy soils with different productivities in Sichuan Basin. The approach involved comprehensive analyses of soil physical and chemical properties, as well as enzyme activities and microbial community struc...

Historical soil survey paper maps are valuable resources that underpin strategies to support soil protection and promote sustainable land use practices, especially in developing countries where digital soil information is often missing. However, many of the soil maps, in particular those for developing countries, are held in traditional archives that are not easily accessible to potential users...

In the present study the effect of sewage water and canal water irrigation were compared by their physicochemical properties and heavy metals concentration in soil. The mean values of different physico-chemical parameters and heavy metals were : Bulk density (gm/cm) 1.26, Water holding capacity(%)-53.60, Temperature(oC)-16.33, Electrical conductivity (dsm-1)0.122, pH-7.5, Organic carbon (%)-1.9...

Decaying wood is related to nutrient cycling through its role as either a sink or source of nutrients. However, at micro scales, what is the effect of decaying logs on the physical, chemical, and biotic characteristics of the soil underneath? We took samples from a 0 to 5 cm depth under and a 50 cm distance away from decaying logs (Dacryodes excelsa and Swietenia macrophylla) at 2 stages of dec...
