The ARC-Institute for Soil, Climate and Water had modest beginnings in 1902 as the Division of Chemistry in the Transvaal Department of Agriculture. Various changes not only in name but also in focus have taken place over the years to constitute the current Institute which is still well known for its Analytical Services laboratory.

The ARC-ISCW laboratory is a member of AgriLASA Proficiency Scheme for soil, water, plant and fertilizer matrices. The laboratory is also a member of the Wepal Proficiency Scheme for Soil. The Institute is currently in the process of obtaining accreditation for the Water and Special Analysis Labs.
