This analysis was preformed on the soils that were excavated from the pond last year. To establish a pasture w/ legumes they recommend Nitrogen 20-40(#/A) , Phosphate 80(#/A) and Potash 85(#/A) for the first year. The second and third year applications for Nitrogen and Potash are the same but phosphate drops to 45 (#/A).
