Need some help with a food plot question. Lease in Dallas Co Alabama. Very sandy soils, limed two years ago. Planted using 13-13-13 fertilizer, Oats, Wheat, New Zealand Brazacous (sp) (Biologic). These plots got rain on them two days after planting, came up beautifully and were the best we have ever had at that point. Over the past four weeks they have turned a yellow brown color not all over but most areas of the patchs accept for a few spots in each patch. We have been very dry over the past month, but does anyone have an idea about what kind the problem this may be?
