Agricultural Methods
Fertiliser Testing
Fertiliser and Nutrient Feed come in many forms. The key to performing accurate testing is in the sample preparation. Solid fertilizer will need to be mixed with deionised water and diluted to the appropriate concentration. This will normally be 5g of fertilizer...
Soil Testing
Soil testing requires some sample preparation before analysis can take place
The Determination of Sulphate in Water
As there is no direct measuring Sulphate ISE the analysis is performed using a sample subtraction technique with a Lead ISE as the sensor.
Determination of Potassium in Soil
Immerse the electrode in each of the standards in increasing concentration steps in the calibration mode of the Ion Meter.
Determination of the pH of Mineral Soil
The pH of a mineral soil is defined as the pH, measured potentiometrically, of the suspension obtained by shaking the soil with water under controlled conditions.
Calcium in Soil
Calcium in soil is a good indicator of soil health and can be measured using a Calcium ISE and portable ion meter.
Measurement of Soil pH
Measurement of soil pH is important as all crops have an optimum pH level at which they are able to produce higher yields.
