He Cut Fertiliser 40%… Then This Happened

Farm Learning with Tim Thompson | 23 May 2026 | Back to All Videos
This South Australian grain grower cut fertiliser rates by up to 40% and started focusing on soil biology. The results surprised even him.

Can changing biology, silicates, and plant stimulants increase resilience, improve protein, and keep crops hanging on through dry seasons?

Today we’re near Goyder’s Line in South Australia with Paul Schutz, managing around 4,500 hectares in one of Australia’s toughest grain-growing environments. Paul explains how reduced synthetic inputs, carbon sources, biological stimulants, silicates, and tissue testing are changing soil structure and crop performance.

If you farm in marginal rainfall areas, grow cereals, or want to improve resilience and reduce input costs, there are practical ideas here worth testing.

Topics covered include soil biology, reduced synthetic fertiliser systems, silicates, carbon buffering, crop resilience, grain protein, tissue testing, biological stimulants, termites as indicators of activity, and practical dryland farming management.
