In this week's podcast, discover how optimising soil health is your key to farming profitability. We're joined by Melinda Turner from Farm Nutrient Advisory, a specialist in the fields of animal science, soil and plant sciences. Melinda brings a straightforward, no-nonsense approach to this complex subject.  Melinda discusses some of the common challenges in nutrient management. It's such a vast topic and, with many 'snake oil' sales people out there, it’s no wonder many farmers find it overwhelming. Melinda runs us through mineral imbalances in the soil, like low levels of calcium among others, and how they affect other nutrients and their availability.  “You quite often get high potassium soils that can play havoc with magnesium interaction and also in terms of your calcium uptake, because the magnesium is needed for the hormone release that triggers calcium absorption,” she explains. “So, if you've got too much potassium in your soil and you're not applying appropriate magnesium and calcium, you can have quite a knock-on effect with a number of those minerals and vitamins as well. " Melinda also shares her expertise in soil testing and analysis, underscoring its importance in maintaining optimal nutrient levels. She advises regular testing, "For both soil and herbage, every couple of years would be a minimum." She highlights that the cost of extra testing is soon reaped by the benefits of healthier, productive and, more importantly, optimised livestock, soils and forage.  She also highlights the importance of how variable soil conditions are from farm to farm, so relying on what your neighbours, or the local fert rep, tells you to do, without proper scientific testing beforehand, can waste a lot of time and money.  And, of course, we dive briefly into the world of genetics with Melinda explaining how soil health influences genetic expression in plants, much like nutrition does in livestock. Tune in to gain valuable insights into nutrient management and its crucial role in successful farming.  Head Shepherd is brought to you by neXtgen Agri International Limited, we help livestock farmers get the most out of the genetics they farm with.
