Almost all of my soils are acidic and suggest a N to K equal ratio except for bermuda naturally needs more N. What general guidelines can you give?
On another subject what do you do differently fert/herb wise to grass that grows in heavy shade?
In acidic clay soils, dependent on calcium levels, a good nitrogen source is calcium nitrate. This is almost like liming the soil minus the dusty mess and slow reaction. On acidic soils, most of my N comes from calcium nitrate instead of ammonium sulfate. In another thread, I detailed three or so different soil conditions I deal with. The fertilization program changes dependent on the soil. I do not have the good fortune of one type of soil. A one size fits all "lawn fertilizer" blend might get the grass green. But at what long term cost?
