Cl.

This is a soil salinity test. This method quantifies the concentration of chloride in a saturation paste extract. Chloride may be determined using an ion selective electrode (potentiometric), chloridometer or ion chromatography instrument methods. Plant tolerance to chloride can be related to its concentration in the soil saturation paste extract. The method detection limit is approximately 0.1 mmolc/L dependent on the method of analysis and is generally reproducible within ± 10%.

This method determines the concentration of chloride in botanical materials. It is determined by coulometric titration or ion selective electrode. The method detection limit is approximately 10 mg/kg (sample dry basis) and is generally reproducible to within ± 10.0%. Cl.

Cr. This test method determines the concentration of chromium in a water sample by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES).The method has a detection limit of 0.005 mg/L.

This method quantitatively determines the concentration of chromium in botanical materials utilizing a nitric-perchloric acid digestion. Digest analyte concentrations are determined by atomic absorption spectrometry (AAS) and/or inductively coupled plasma atomic emission spectrometry (ICP-AES). The method detection limit is approximately 0.5 mg/kg. Cr.

This method quantitatively determines the concentration of cobalt in botanical materials utilizing a nitric-perchloric acid digestion. Digest analyte concentrations are determined by atomic absorption spectrometry (AAS) and/or inductively coupled plasma atomic emission spectrometry (ICP-AES). The method detection limit is approximately 0.5 mg/kg. Co.

This package determines the macro nutrient content and moisture percentage of a compost or manure sample. C, N, P, K, % Moisture, C:N Ratio.

This test determines the moisture percentage in a manure or compost sample. % Moisture.

Cu. This is soil composition test by acid digest. This procedure analyzes the concentration of copper by utilizing a nitric acid/hydrogen peroxide closed vessel microwave digestion. Determination is by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). The approximate method detection limit is 1 mg/kg.

Cu. This test method determines the concentration of copper by utilizing an acid digestion and determination by atomic absorption spectrometry (AAS). The method has detection limits ranging from 0.1 mg/Kg. The method is generally reproducible within 8%.

Cu.

This is a soil fertility test. The DTPA micronutrient extraction method is a nonequilibrium extraction for estimating the potential soil bioavailability of copper for neutral and calcareous soils. Analyte concentrations are determined by atomic absorption spectrometry (AAS) or inductively coupled plasma atomic emission spectrometry (ICP-AES). The method detection limit is approximately 0.1 mg/kg and is generally reproducible ± 10%.
