Video Description from Youtube:

Soil pH affects everything—from plant growth to stock health.But many farmers don’t realise how dramatic the impacts are… or how to test for it properly. In this episode, we dive into the fundamentals of soil pH, how it works, and how to measure it right on your farm.

Using basic tools (and a pocket knife), we explore what happens as acidity increases, what pH means on a log scale, and how acid or alkaline trends at different depths impact your productivity. We also show how to sample correctly, why most farmers get it wrong, and how to use a multi-indicator soil pH test kit tailored for Australian soils.
