Host Alister introduces Digging Deeper Ag Chats and speaks with Pete Norwood of Full Circle Nutrition after he contributed to the Gippsland Soil School, including a practical farm visit at Rohan Bigley’s. Pete recounts growing up on a mixed farm near Mendooran, NSW during the 1982 drought, studying ag science at Charles Sturt University, and later building farms in Stratford and now Seaspray with challenging sandy and saline soils improved with gypsum and lucerne establishment. He describes a pivotal shift toward Kinsey-Albrecht concepts after solving downer cow problems via phosphorus and discovering soil-plant mineral imbalances, emphasizing calcium’s role in soil structure and the need for reliable soil and plant testing (including Albrecht methods, total tests, and sap/tissue analysis). Discussion covers nitrogen use and cofactors, sulfur leaching and application, foliar strategies, and the Growing More Topsoils project at Gippsland Research Farm and its expansion to Skeene Creek, where treatments have increased topsoil depth and improved clay structure, aiming to boost resilience and water-holding capacity.
