Arva, Ontario | If you’re knowingly high in P, then why are you simply shuffling your analysis around and staying with something with a substantial amount of P?
Need more pieces of the puzzle. Assume you have a chunk of manure going on - what are your other soil tests, especially K. Corn silage removes a pile of K.
If your P test is high, and your K test is stout as well, I’d broadcast a urea/AMS blend, and leave the planter empty. If you have high tests of P and K, your likelihood of economic response is about nil, unless you have variable soils.
We’ve done a fair bit of work with starters ‘here’ in our soils and climate. Starters will almost always create a visual payoff, but seldom an economic one if soil tests are high. If you are marginal to low in levels, then they almost always generate an economic return.
Good soil testing will help make that decision.
