Complete Fertilizer with Lime, N P K L (Plats 152, 64 and 92). Where lime was used in combination with the three fertilizer constitu- ents there was less cotton produced on all the plats in all three of the fields than where the three fertilizer constituents were used without lime, showing a net loss in the use of lime in combination with a complete fertilizer for the production of cotton on this soil. Taking the experiments as a whole, the average results show that nitrogen alone on this soil for the production of cotton was used at a loss; Potash alone gave a small profit; nitrogen and potash combined gave less by practically one-half than potash alone; Lime alone had very little efl^ect on the yield ; Phosphoric acid alone gave a large increase in yield and profit.
