Paddock Trials: Test Farm Inputs Cheaply

Farm Learning with Tim Thompson | 30 June 2026 | Back to All Videos
Farm input trials don’t have to be expensive, complicated, or left to researchers. Here’s how to set up a simple paddock trial so you can test fertiliser, biological inputs and soil products before spreading them across the whole farm.

How do you know if the product you’ve been sold is actually working?

In this Farm Learning video, Tim Thompson is joined by Ben from Greenmate Agriculture to set up a practical paddock trial before applying Humate 9 biological input. The aim is simple: compare a treatment area against a control area, collect a useful baseline, and measure whether the product is actually moving the farm in the right direction.

The video covers how to choose a fair trial paddock, why two similar-looking paddocks are not always equal, how trees, aspect, slope, neighbours and previous management can affect results, and why biological inputs need a longer trial period than many conventional fertiliser responses.

You’ll also see the basic tools used to collect paddock data without spending a fortune: notebook records, photos, soil temperature readings, pH and moisture testing, Brix testing with a refractometer, worm counts, root observations, soil aggregation checks, and repeat sampling across both treatment and control areas.

This is useful for farmers, contractors, landholders, small property owners and anyone using fertilisers, humates, biological inputs, soil amendments, pasture products or regenerative agriculture systems who wants to make better decisions from real paddock evidence.

A good paddock trial helps remove the guesswork. Was it the season? Was it rainfall? Was it soil history? Was it the product? A simple control versus treatment setup gives you a much clearer answer.

This video connects to practical topics including paddock trials, farm input testing, biological farming, soil health monitoring, pasture management, soil pH testing, Brix testing, humate products, regenerative agriculture, soil biology, pasture response, treatment and control plots, and how to measure whether a farm product is working in real-world conditions.
