SK100 Soil pH and Lime Requirement Kit

Soils are often described as acidic, neutral or alkaline.  Soil pH values around pH 7 are neutral, below pH 7 are acidic and above pH 7 are alkaline.  pH is important as it influences the availability of essential nutrients.  Crops can exhibit deficiency symptoms in soils where there are adequate concentrations of  nutrients but due to pH conditions they are less available for absorption by plants.

The critical step in any analysis is taking representative samples.  Nutrient distribution across an area can be extremely variable, so it is good practice to test a composite of a number of individual soil samples.  Separate samples should be collected from each area of differing soil type, previous cropping history or soil management.  Be sure to test any areas of particular concern specifically for more detailed analysis.

The methods used for colorimetric and photometric involve an extraction process, creating a highly ionic solution. This in turn requires a slightly different formulation of colorimetric/photometric reagent than that used in water-based samples to provide effective colour development.

In summary, to measure soil parameters correctly requires the use of the soil reagents developed specifically for that purpose. We manufacture a range of soil test kits, with each specification offering a configuration designed for a different application, from simple measurement of key nutrients through to complete portable soil analysis laboratories.

We provide all the necessary parts and consumables within each kit, making it easy to select the kit you need to begin testing straight away. View each kit page on this website to see which reagents are included in each kit, and we also list the part codes of each component to aid procurement of additional and/or replacement consumables.
