Organic farming. It comes to mind that production of crop naturally without chemicals, better nutrition but lower yield. But Dr Naveed has proved that with his bio fertilizer yields are higher, even static yields are improving. I personally visited and witnessed more than 80 rice tillers per hill and very wonderful moringa crop. All you need is a fermentor, C source and inoculumn. University of Agriculture Faisalabad is willing to help the farmers.
