Your fertiliser programme. Built for your soil.

Start at the top with pH and acid saturation, because those two decide whether anything else you apply will actually be taken up. On an acid soil, phosphorus is locked up by aluminium and much of what you spend on it is wasted, so correcting the acidity comes before the fertiliser. Then look at the main nutrients: phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulphur (S), usually reported in mg/kg. Then the micronutrients: zinc, boron, copper and manganese. Compare each figure against what your crop removes at the yield you are aiming for, which is the gap the programme has to fill. If you upload your report here, we read those figures off it, show you every one of them on screen and flag anything we were not confident about, so you can correct it before we build anything.

There is no single answer, and anyone who gives you one without seeing your soil test is guessing. Cabbage is a heavy feeder, particularly of nitrogen, potassium and calcium, but what you actually need to apply is the gap between what your soil already holds and what the crop will remove at your target yield. That is the calculation this wizard does: it reads your soil test, compares it to the removal figures we hold for the crop, and gives you a week by week programme with quantities. If cabbage is showing as available in the crop list, we hold a verified South African planting rate for it. If it is showing as programme on request, we do not, and we will build it for you by hand rather than guess a rate.

It depends on your acid saturation, not on your pH alone, and it depends on whether your soil is short of magnesium. We work the figure out from the acid saturation on your soil test and tell you whether to use calcitic or dolomitic lime, based on your calcium to magnesium ratio. We will not put a number on it without seeing your test, because the wrong lime rate is expensive in both directions. Two things worth knowing. Lime takes six to eight weeks to work, so it goes on well before planting. And RegenZ does not sell lime or gypsum: we give you the recommendation in tonnes per hectare only, you buy it locally, where most of the delivered cost is transport, and it is never on our quote or in our total.

Upload a PDF, a photograph of the page, or a spreadsheet, up to 10 MB. We read Bemlab and FAS (Department of Rural Development) layouts directly, and we try to read other labs as well. Whatever we manage to read, you see every value on screen before anything is built, and you can correct any of it. Anything we could not find on your report is left blank rather than filled in with an assumption, and anything we were not confident about is flagged for you to check. If we cannot read your report at all, you can type the values in by hand and carry on, or WhatsApp it to us on 063 412 5473.

No, and we will not pretend otherwise. This programme is generated automatically from the soil result and the details you supply. No person has looked at it. It does not know your field history, your cultivar, the disease pressure in your area, your water quality or the season you are having. RegenZ does not employ a SACNASP registered agronomist, so nothing here is a substitute for advice from one, and the same wording appears on the programme and on the PDF. Confirm the rates and the products before you apply anything. If you want a person to look at your soil test, WhatsApp us on 063 412 5473 and we will.

You can build a full programme and see the whole quote without giving us your name. Nothing that identifies you leaves your device until you have read the consent wording, ticked the box and tapped the button, and the box is never ticked for you. When you do send them, RegenZ (Pty) Ltd stores your name, farm name, email, WhatsApp number, province, your soil values and the quote we produced, and uses them to produce your quote, send it to you and talk to you about it. We do not sell your details. You can ask us to delete everything we hold about you at any time and we will. The consent wording is versioned, so we can always show you exactly what you agreed to and when.
