In this episode of Voices from the Field, NCAT Sustainable Agriculture Specialist Nina Prater and her husband, Jeremy Prater – a cattle and meat goat farmer – explore the science and history of potassium. Potassium fertilizer prices have increased 45 percent in the past few years over the historical average, and finding ways to reduce the need for off-farm inputs of potassium can improve a farm’s bottom line. Nina and Jeremy discuss potassium in the soil and in plants as well as the human history around this element. They then share different ways to manage soils sustainably and require less off-farm potassium fertilizer.
