This PowerPoint covers the visual symptoms caused due to deficiency of different plant nutrients. It includes the deficiency symptom of Nitrogen, Phosphorous, Potassium, Calcium, Sulphur/sulfur, Iron and other. Besides the visual symptom, it also includes the correction measure to reclaim the deficiency of these mentioned nutrients. The reader will be clear about deficiency symptoms caused by several macronutrients and micronutirent.
