Independent agricultural services · Western Cape
Integri Ag is an independent agricultural services company. We measure your soil, your crop and your water, then make sure the right inputs go on at the right rate, so every rand and every drop works harder. We aren't tied to any fertiliser, chemical or equipment supplier.
Where farms lose money
Grain margins are thin, and fertiliser and lime are among the biggest costs per hectare.
What we do: We make sure the correct inputs go on, at the correct amount, in the correct place. No fluff, nothing you don't need.
Grain →Electricity and water cost more every season, and water that drains past the roots takes your fertiliser with it.
What we do: Comprehensive irrigation scheduling with soil moisture probes, to raise irrigation efficiency and make every drop count.
Irrigation scheduling →By the time you can see it from the bakkie, the damage is done.
What we do: NDVI satellite monitoring flags stressed patches early, so we scout exactly there and you can act sooner.
Satellite monitoring →When the person advising you also sells the product, “apply more” is always the easy answer.
What we do: We're independent and paid only for the advice, so “apply less” is an answer too.
Why independent →One composite soil sample hides the problem, and the correction misses the patch.
What we do: GPS grid sampling, topsoil and subsoil, shows exactly where and why, and the prescription follows the soil.
Soil sampling →A shortage costs yield long before it shows on the leaves.
What we do: Leaf analysis through the season catches shortages early, while there is still time to correct them.
Leaf analysis →Why independent
Much of the agronomy advice a farmer receives comes from someone who also sells the product. Integri Ag works the other way round: we're paid for the advice and the monitoring, and nothing else — so the right answer can be "apply less", "apply nothing" or "apply it somewhere else".
We recommend products by what they contain and what your soil needs, from whichever supplier you prefer to buy from.
Soil grids, leaf samples and probe readings come first. Programmes are built on your numbers, block by block.
We follow up with leaf analyses and the next survey, so you can see whether the advice actually worked.
Services
Every recommendation starts with a measurement and ends with something you can act on — a programme, a map, or a file the spreader can read.
The agronomy package
Taken as a package across your participating hectares, so nothing waits for someone to remember to ask.

Every land sampled on a GPS grid, topsoil and subsoil, so next season's results sit on the same points and you can see what moved.
0–150 mm & 150–300 mm · GPS logged
Lab results mapped for pH, P, K, Ca, Mg, Na and the micros, with base saturation and the ratios that explain why a block underperforms.
Ca 68% · Mg 12% · K 4% · Na 2% targets
Lime, gypsum, potassium and phosphorus worked out per zone and exported as a shapefile that loads straight into the spreader monitor.
SHP · John Deere, Case IH, New Holland
A season programme per block, built on the soil and leaf record and specified by nutrient — not by brand — and reviewed in season.
Programme per block · supplier of your choice
How the crop and the soil are responding
Sampled through the season and read against the crop's sufficiency norms, so a deficiency shows up as a trend rather than a surprise at harvest.
Trends per block, season on season
Capacitance probes read by root zone against their refill and full points, so irrigation follows what the profile holds instead of the calendar.
600 mm profile · refill points in mm
On-farm rainfall, temperature, humidity and leaf wetness, read alongside the probes for irrigation and disease-risk decisions.
Read alongside the probes
NDVI imagery per field through the season flags stressed patches early, so we scout there for pests and disease before the damage spreads. Several seasons of history also give productivity zones for variable-rate work.

Each service in detail
Monitoring · your data
We keep every map, lab result and probe reading for every season we work together, so this season's numbers always sit beside last season's. It's your record, and it stays yours.
Crops we work in
The approach is the same across them; the norms, the sampling depth and the timing are not. Pick a crop to see the season we work to.
How we work
1
Grid sampling across the land, topsoil and subsoil, each point recorded where it was taken.
2
Accredited lab analysis, then independent interpretation against base saturation and the crop's own norms.
3
Rates per zone for lime, gypsum, K and P, with the cost and the expected correction stated up front.
4
Leaf samples, probes and the next survey show whether the correction did what it was meant to.
Who we are · Landbou met integriteit
Vision
To be South Africa's leading independent agricultural company.
Mission
To work hand in hand with farmers, giving them the scientific, data-driven resources they need to improve their farming practices and reach their best productivity.
What you get back
Rates are worked per zone and rounded to what the spreader can actually apply. Where a correction is larger than one pass should carry, we say so on the map rather than quietly capping it.
White dots are sample points; zones follow the grid.

Questions
We sample your soil, leaves and water, interpret the results and advise on what to apply, where and how much, without selling the products. You buy from whichever supplier you choose.
Our office is at 2 Agri Boulevard, Durbanville. We serve farmers all over the Western Cape (from the Swartland and Sandveld to the Olifants River Valley, the Hex River and Berg River areas and the wine regions) and nationally.
Nothing. We walk the lands with you, look at what you already have (soil and leaf results, probe data) and tell you honestly where the gains are. There's no obligation.
Wine and table grapes, citrus, pomegranates, lucerne, grains, canola and vegetables such as tomatoes and onions.
Six guaranteed farm visits with written reports, soil and leaf analyses on all crops, satellite NDVI imagery, fertiliser programmes on request, irrigation scheduling with probes, and benchmarking against other production areas.
Yes, we work in Afrikaans and English. The whole website is also available in Afrikaans.
