Trial results and farm records
Grower practice on one side.WormGro on the other.
Every figure on this page is from a paired trial or a farm record, as WormGro has published it. Capsicum, ginger, macadamia, lucerne, oats and ryegrass. No modelling, no averages of averages.
- Capsicum: yield +27%, cost -29%
- Ginger: marketable yield +31%
- Macadamia: +402 kg/ha nut-in-shell
- Lucerne: irrigation halved
Cross Family Farm, block 3A · February to June 2021
One capsicum block, five months, every number up.
The grower kept the standard program on one side of the block and ran WormGro on the other. Yield, fruit size, soil chemistry, Brix and cost were all recorded. The soil moved as much as the crop did.

Reading the soil table
Nitrogen, calcium, potassium and phosphorus all roughly doubled in the soil test on the WormGro side, in a season where the crop was also pulling more out. That is bound nutrient being released, not nutrient being added. Cation exchange capacity, the soil's ability to hold those nutrients, rose from 5.8 to 9.8.
Ginger · 2022 season
More marketable rhizome, far less pythium.
Pythium is the soil-borne rot that takes ginger crops. On the WormGro side the disease pressure fell in both the rhizome and the leaf while the saleable weight per plant went up.
+31%
Marketable yield per plant
186.6g to 245.3g
47.6% to 26%
Rhizomes infected with pythium
55% lower
15.3% to 1.98%
Leaves infected with pythium
Same crop, same season
Macadamia · orchard trial
Another 402 kilos of nut off every hectare.
Against the untreated control, the WormGro rows yielded 6,704 kg/ha of nut-in-shell to 6,302 kg/ha, a 6.38% lift on a mature orchard where small percentages are large money. A further orchard trial is still in progress.
| Nut-in-shell | kg/ha |

| Untreated control | 6,302 |
| WormGro | 6,704 |
| Difference | +402 (+6.38%) |
Farm records
Hay, pasture and oats, in the growers' own words.
Not trials, just farmers who kept their records.
“Prior to application it needed 4 waters and produced an average of 25 bales an acre. After WormGro we needed only 2 waters and got up to 30 bales an acre. The plants look considerably stronger and healthier.”
Lucerne hay · 16 acres black clay · 20L/ha WormGro · nil synthetics
Watering halved, 25 up to 30 bales per acre
“The oat hay came up so healthy. Other local farmers have been stopping to ask what I put on it, assuming I'd used heaps of urea. When I tell them it was only WormGro, they can hardly believe it.”
Oats for hay · 8ha · 1 x 20L/ha WormGro Balance foliar · $60/ha
262 bales per acre, confirmed 24.10.2025
“I put MAP and Calciprill on both plots. One got 100 kg of urea per hectare and the other WormGro Plus. The results were just as good with WormGro, but it worked out a lot cheaper.”
Ryegrass pasture · 4ha · 2 x 5L/ha WormGro Plus foliar
Matched urea at lower cost
How a WormGro trial is run
Same block, same day, same rig. Then weigh it.
The only way a number means anything on a farm is if the other side of the paddock got everything the same except the product.
Paired strips
The standard program on one side, WormGro on the other. Same seed, same operator, same date.
Soil test, before and after
Carbon, the major nutrients and cation exchange capacity, so the soil change is measured, not assumed.
Brix in the field
Leaf and fruit readings through the season as a running check on plant health.
Yield and cost at the end
Weighed at harvest and costed per hectare, because that is the number the business runs on.
About the data
GSP, Brix and what you can expect.
Grower standard practice: the fertiliser program the farm was already running, applied on its own side of the same block in the same season. Every WormGro figure sits against that, not against an untreated strip or a textbook average.
Because the WormGro side replaced inputs rather than adding to them. The capsicum block ran at $50 a hectare against $70 for the standard program, and still yielded 27% more. Biology does jobs the grower had been paying synthetics to do.
We will not promise it. Soil, season and management all differ, which is why we encourage a paired strip: your program on one side, WormGro on the other, weighed off at harvest. The trials on this page are what that approach produced on other farms.
The capsicum trial ran from February to June 2021, one crop cycle. The ginger results are from the 2022 season. The farm records are the growers' own figures over their normal hay or pasture cycle, confirmed on the date shown.
Brix measures dissolved sugars in the sap and is a quick field proxy for plant health. Higher Brix plants photosynthesise harder, taste better and are a poorer target for pests and disease, which is why the capsicum trial recorded it in both leaf and fruit.
