B.

This procedure determines the boron concentration in a soil saturation paste. It is determined by Inductively coupled plasma emission spectrometry (ICP-AES) using one of three wavelengths. The method quantifies soil boron concentrations which can limit crop yield or be toxic to plant growth. The method detection limit is approximately 0.10 mg L-1 and is generally reproducible to within ± 8%.

B. This test method determines the concentration of boron by utilizing an acid digestion and determination by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). The method has detection limits ranging from 0.1 mg/Kg. The method is generally reproducible within 8%.

BD.

Bulk density is the relationship of mass and volume of the soil. It is determined by drying the soil and determining the dried mass. The mass is then divided by soil volume.

Cd. This test method determines the concentration of cadmium by utilizing an acid digestion and determination by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). The method has detection limits ranging from 0.1 mg/Kg. The method is generally reproducible within 8%.

Ca.

This is a soil salinity test. This method quantifies the amount of calcium in a saturated soil. By extracting the liquid phase of the saturation paste under partial vacuum, it estimates Calcium (Ca 2+). The method is generally reproducible within ± 12%, dependent on the soil textural class.

Ca. This test method determines the concentration of calcium by utilizing an acid digestion and determination by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). The method has detection limits ranging from 0.1 mg/Kg. The method is generally reproducible within 8%.

CaCO3.

This method is determined by the loss of carbonates, in the form of carbon dioxide, in excess hydrochloric acid. Calcium carbonate (lime) is measured to determine soil buffering capacity. This procedure estimates the free calcium carbonate in a sample. The method detection limit is approximately 0.2% CaCO3 equivalent.

CO3.

This is a a soil salinity test. This procedure quantifies carbonate (CO3 2-) concentration in mmolc/L in a soil saturation paste. The concentration of bicarbonate affects the solubility of calcium, the ionic strength of the extract solution and is used to calculate the adjusted sodiuim adsorption ratio. The method detection limit is approximately 0.05 mmolc/L and is generally reproducible within ± 10%.

This is a soil salinity test. Cation exchange capacity (CEC) is the measure of a soil to retain readily exchangeable cations which neutralize the negative charge of soils. This method involves saturation of the cation exchange sites with ammonium. This method maybe poorly suited to soils containing carbonates, vermiculite, gypsum and zeolite minerals. The method detection limit is approximately 1.0 cmol/kg and is generally reproducible within ± 10%.
