Trials

The protocol is public before the results are.

Composition and microbiology are laboratory-verified. No yield trial has completed. Results publish here either way, positive or negative.

Current state

What is running.

No trial engagements published yet; [N] places open this season.

A row appears once a grower has signed, a baseline soil test is on file and a result date is set. A date that passes without a result renders as overdue.

The protocol

How the product is applied in a trial.

One question: can starter nitrogen come down 20 to 30 percent without losing yield.

15 to 25 L/ha banded in furrow at planting. Season cap 30 L/ha where fertigation follows. Conditions below from the Eco Veritas interpretation.
  1. Jar test, then one small block

    Test the tank mix you actually use, in a jar and then in the field, before anything runs at scale.

    Page 11, section 5

  2. Dilute at least 1:10

    One part product to ten parts water in furrow. Ammonium reads 244 mg/L and conductivity 374 mS/m, and both scorch germinating seed at full strength.

    Page 11, section 5.1

  3. Band beside or below the seed

    About 5 cm to the side or below, or through the irrigation line. Concentrated product never touches the seed.

    Page 11, section 5.1

  4. Keep the fertility programme

    A microbial inoculation with a little starter nutrition. Not a line item in the nutrition plan.

    Page 11, section 5.1

  5. Take care with salt in dry regions

    Repeated undiluted use builds soil salt in low-rainfall soils. The interpretation names North West and Free State.

    Pages 11 and 12

  6. Nothing close to harvest on edible grain or feed

    Apply early, well before grain fill, or to the soil instead. The reason is the opportunistic bacteria and the aflatoxin-forming Aspergillus DNA.

That target is the protocol author’s recommendation. No completed trial stands behind it, which is why these trials exist. Foliar application is in no protocol we publish until phytotoxicity, pathogen and residue testing reports.

The gate

What a grower signs up to.

Five hectares, minimum
Below five, a paired comparison cannot carry field variation and the result survives nobody's scrutiny.
A paired control
Treated strips beside untreated strips. Same soil, planting date, irrigation and fertility programme. One variable changes.
A baseline soil test
Accredited laboratory, before the first application, at the grower's cost. Without it the end-of-season numbers describe nothing.
Consent to publish either way
Signed before the trial starts. A trial that shows no response publishes here in the same detail as one that does.
A capped number of places
Each place is an agronomist's season. Places are limited and applications are read in order.

Apply for a place.

Crop, hectares, soil type, irrigation, and the laboratory that will run your baseline. An agronomist answers whether the field suits a paired trial.
