Those P levels are fine. P builds really easy and hold really easy in the soil compared to the other nutrients. That is low for K levels though�.K also has an effect on pH as well and is part of getting things in balance�..it�s one of your cations just like Ca. It has a positive charge�. K levels and Ca levels will both build up and hold better as you build organic matter into your soil. I�d bring back a bag of 33-0-0 and a bag of 0-0-60 per acre on the next trip. Just for future plantings you would have wanted to have already added your 0-0-60 several weeks ago. You�re really feeding the 0-0-60 to the soil�not the plant. You feed the soil to get the nutrients levels where they need to be and the soil feeds the plant. Add another bag of 0-0-60 per acre later this summer before fall planting. This will start getting your K levels up. You could really go ahead and add two bags of 0-0-60 right now if it doesn�t get into your planting budget too deep. You probably won�t need any P for a while so skip the 13-13-13 and use 33-0-0 and 0-0-60 for your fert needs. If you add two bags of 0-0-60 now then I�d test later this fall again to see where you�re running around September. It may be that you only need to add a little N this fall. I made a mixing barrel that I throw all of my seed and fert into for an acre and mix it altogether instead of making multiple passes for seed and fert.
