Spatial Variability Analysis of Soil Properties within a Field

The main efforts and applications up to now are focused on the spatial variability analysis within a field. The spatial variability of soil properties within a field was evaluated using geostatistical analysis and the interpolation methods for mapping soil properties were compared in this paper. This experimentation was conducted in a wheat field of the trail farm in Shunyi County, Beijing. The...

Spatial Variability of Root Knot Nematodes in Relation to Within Field Variability of Soil Properties

Site-specific management (SSM) of cotton (Gossypium hirsutum L.) fields under risk of southern root-knot nematode [M. incognita] (RKN) infection may offer producers better management of on-farm resources and optimization of profitability. However, it requires the study of RKN spatiotemporal variability and the identification of surrogate data spatially correlated with its occurrence. The object...

Changes of soil organic carbon in an intensively cultivated agricultural region: a denitrification-decomposition (DNDC) modelling approach.

Regional modelling of soil organic carbon (SOC) dynamics is important for predicting large-scale patterns in carbon cycling and for assessing potential responses of soil carbon pools to land-use change. However, data uncertainties related to both spatial heterogeneity and small-scale differences in farming practice related to cropping systems affect the accuracy of regional models. A case study...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Radiometric properties of virgin and cultivated soil around the Shazand Refinery Complex in Iran

Background: One of the main sources of exposure to radiation is terrestrial radionuclides in the environment. These radioisotopes are present in the Earthchr('39')s crust and can be increased by human activity such as mining of coal, oil, and minerals. Materials and Methods: In this study, 39 soil samples including virgin and cultivated were collected from around of the Shazand Refinery Complex...
