The customer doesn't really understand what you are trying to accomplish in the soil. Hardly anyone understands what we are accomplishing in the soil. When we look at 'organic' NPK inputs to match the amounts of synthetic NPK, then we can be pretty sure that not much is understood about what is going on in the soil. I am not trying to be funny, arrogant, arguementive, or any such thing of the like. The problem is any thought out of time with anyones' preconcieved notions is quickly mocked and goes no where. Can a compost with .5/.5/.5 (NPK) be applied to seed and be an adequate 'starter fertilizer'? In most normal soils the answer is yes. Not because of the P amount in the 'fertilizer', but because of what is happening in the soil.
