The concept of crop rotation dates back thousands of years, with ancient civilizations such as the Mesopotamians and Egyptians employing rudimentary forms of rotation to sustain their agricultural endeavors. The basic principle behind crop rotation is alternating the types of crops grown in a particular field over time to improve soil fertility, control pests, and maximize yields. In traditional ...
Soil nutrient testing equipment has revolutionized the field of agricultural management. ...
In addition, soil testing is not only used in field soil testing, plant nutrition diagnosis and fertilization diagnosis, but also has important guiding significance for field production. In soil testing and fertilizer formulation, the measured values of ...
This can happen due to flooding (natural causes) or irrigation (manmade causes). When the soil is waterlogged, the amount of gases, including oxygen, diffused in soil decreases. ...

The application of veterinary medical products (VMPs) to livestock can impact soil organisms in manure‐amended fields or adversely affect organisms that colonize dung pats of treated animals, and potentially retard the degradation of dung on pastures. ...
The common solution is to lime the soil which increases pH, reducing metal toxicity and encouraging recovery. ...
ABSTRACT Field tests for the detection of lead in soil are not frequently accepted, since the tests are rather cumbersome or not reliable for screening determinations. ...

Phosphorus from agricultural lands poses a problem in water resources. In 2003, more than 48% of soil samples submitted to the North Carolina Department of Agriculture and Consumer Services (NCDA&CS) soil testing laboratory tested very high in soil P (>120 mg dm–3 P). As soil ...
Soil sampling approaches have been compared based on soil-test variation. ...
The performance of the PRB was evaluated by monitoring the distribution of the oil emulsion in the aquifer, the impact of the oil injection on the aquifer permeability and groundwater flow paths, and the changes in contaminant concentrations and biodegradation indicator parameters both upgradient and downgradient of the PRB. Data obtained during the pilot test were used to ...
Laboratory tests were used to determine geotechnical and physicochemical properties and mineralogical composition. The results of a range of laboratory tests, including oedometer types, filter paper, triaxial, and new stainless steel tank apparatus, showed the problems associated with investigating swell behavior of soils. A ...
Field hydraulic conductivity tests are required to determine the in situ hydraulic conductivity of compacted clay soils used in the liners for hazardous waste management facilities. The test must be capable of measuring hydraulic conductivities of 1 × 10-9 m/s or less, and the values obtained must be representative of the overall ...
A considerable number of in-situ tests have been devised for measuring field soil shear strength parameters. These tests include, among many others, cone penetration and vane shear devices. The conventional form of each of these two devices controls the type of soil deformation, which may limit the use of the ...
ASTM Committee D18.02 on Sampling and Related Field Testing for Soil Investigation (Mr. Ralph Brown, Chairman) suggested that this proposed suggested method be published herein to provide exposure and solicit comments for users. ...
