How can I test soil fertility, NPK, pH and metal content?

Soil testing may be needed for environmental studies, or in farming and horticulture to ensure plants and crops are receiving the right balance of nutrients in the right conditions.

soil test

There are a wide variety of soil test kits available which range from quick tests on a couple of basic parameters through to larger kits including electronic photometers to achieve higher accuracy results on a wider range of tests.

Palintest have one of the biggest offerings of soil test kits in terms of range of specifications – we’ve compared their different kits below to help you choose the best kit for you…


Parameters Covered

Perhaps the most important consideration – what parameters will each kit cover?

The range varies from basic soil pH and lime requirement, NPK analysis or a full analysis including the metals in soil.

The parameters are summarised in our comparison table below

The SK 100 Kit, the most basic kit in the range for pH and Lime Requirement of soils only
The SK 100 Kit, the most basic kit in the range for pH and Lime Requirement of soils only


Instruments Included

Some of the kits include a “multiparameter pocket sensor” – this is a portable pH and conductivity meter, to test these two parameters electronically by a meter.

The two most advanced kits include a Soiltest 10 Bluetooth enabled photometer – again this allows electronic measurement of the parameters by a photometer. This gives higher accuracy results.

The more basic kits work via “tester blocks”, a type of test kit which works on a visual colour comparison basis to get the result. This does make them lower cost and very simple to learn to use, but does give less accurate results as light and personal vision differences will effect the results.

  1. How accurate is the SKW 500 kit ?
    How much will it cost for shipment to Tanzania please. Do we get any discount if we order 5 or more kits ?
    Thank you
