Copper is Elemental - Dr. Steve's ATW Ep 18
Yara's Crop Nutrition podcast - A podcast by Yara - Tuesdays

Before we identified copper as an essential nutrient, we were using it as a natural fungicide. Copper is essential in reproductive systems in the plant. Copper deficiencies are not wide spread, but where there is a deficiency, it is hard to visually identify. Copper effects the reproductive growth but not vegetative growth, therefore the plant may show good healthy growth but actually have a copper deficiency. If you have pH higher than 7 and high organic content, it might be wise to experiment with some copper applications. If you have a comment or suggestion, please leave one at our podcast web page.
