Might not seem like much, but it does add up if done in warm season areas. I have to soil test before selecting my N source. You do not want to be applying ammonium sulfate to soil under pH 6.5. The calcium nitrate I use in an acid soil situation is only good on neutral soils if there is excessive magnesium. Therefore, I soil test before starting a fertilizer program.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
