Soil science salary data in South Africa is limited. PayScale reports an average base salary of R500,000 per year for soil scientists, equivalent to about R41,667 per month, but it rests on only seven profiles updated in February 2026. Indeed’s broader scientist category averages R42,438 per month, or R509,256 per year, from 29 salaries updated on 30 October 2026. Government and consulting adverts rarely state pay. Salaries vary with qualification, SACNASP registration, sector and experience, so treat all figures as indicative.
A soil scientist studies the physical, chemical and biological properties of soil. Their work supports farming, land rehabilitation, environmental assessment and research.
Soil scientists work for government agriculture departments, research institutions, universities, agricultural consultancies and mining and environmental firms.
The occupation differs from an agronomist, who focuses on crop production, and from a geologist, who studies rock and earth materials.

What is the average soil science salary in South Africa?
PayScale reports an average soil scientist base salary of R500,000 per year.
This is equivalent to about R41,667 per month, calculated.
The estimate is based on seven salary profiles updated on 9 February 2026. The sample is very small.
PayScale’s 25th to 75th percentile base range runs from R304,000 to R620,000 per year. The page also reports bonuses of up to R17,000.
The page has inconsistencies. It labels R500,000 both an average and a median, and some summary fields display no usable values.
Indeed’s soil scientist page shows data for scientists in general, which reports R42,438 per month. That is equivalent to R509,256 per year.
Indeed bases it on 29 salaries updated on 30 October 2026, with a range of R23,336 to R77,176 per month. It covers many scientific fields, not only soil science.
OurPower, a critical skills visa guide, lists R30,000 to R80,000 per month for soil scientists. It describes these as market estimates, not official figures.
The three sources broadly agree on a level of about R40,000 per month, but none is a soil science survey.

Soil science salary by experience
Entry-level soil scientist salary
Graduates often begin as technicians, junior scientists or candidate natural scientists while they work towards professional registration.
PayScale reports an average total compensation of R226,235 per year for soil scientists with under one year of experience. That is about R18,853 per month, calculated, from six salaries.
Early-career soil scientist salary
PayScale reports an average total compensation of R249,292 per year for one to four years of experience, based on 13 salaries. That is about R20,774 per month.
These figures include bonuses and overtime, so they are not directly comparable with PayScale’s base salary average. The experience counts also exceed the page’s stated profile total.
Mid-career soil scientist salary
PayScale shows its mid-career and late-career results only as percentage differences with no amounts. A verified mid-career average could not be established.
Senior soil scientist salary
Indeed lists senior scientist and chief scientist averages for scientists in general. Its units are mixed and the figures are not specific to soil science, so they are not used here.
Professional natural scientist and consultant earnings
Registered professional natural scientists can sign off scientific reports. No verified earnings data for consulting or private practice was found.
Soil science salary by location
Soil science work follows farming regions, research stations and mining and environmental projects across the country.

Compare total remuneration
Weigh basic salary, bonuses, benefits and contract length across offers.
What employers should know
Employers should verify SACNASP registration and the registration category required for each post.
Adverts should state the qualification, experience, registration and salary or notch.
Because published data is sparse, benchmarking should combine several sources and recent adverts.
What employees should know
Confirm whether an advertised figure is gross, net or a total package.
Check whether the post requires registration, and in which category, before applying.
Ask about field work, travel and project funding, which affect workload and contract security.
