From Argentina! Quite interesting the video! I have a question. When you talk 60 stp of phosphorus, can you tell me the equivalent in ppm? This is how we measure the phosphorus in Argentina.

[@KYForages]

Divide by 2 and you will have ppm. You must also consider what extractant was being used. At University of Kentucky we use Mehlich 3.

Still fertilizing …. So yesterday

Angie, Merry Christmas! Sustainable hay systems without the addition P and K as fertilizer or manure are nearly impossible since nutrient removal is so high. One option would be to utilize bale grazing on hayfields. Development of strong and sustainable nutrient cycles in well managed grazing systems are much more feasible.
