Re: When do you decide it's time for a different fertilizer?

First thing get a soil test, you can`t manage it if you don`t measure it.  The pH of the soil will determine if you go with Dap or Map phosphate if needed.  If you have sand you might want to "feed the crop" instead of "feed the soil"  as light soils don`t hold nutrients as well as heavy soil. 

 

Some claim putting 10 gallon of low salt liquid on the seed furrow is "all you need" I personally don`t buy it, but to each their own.  My philosophy is "soil is the plant`s stomach" feed the soil and that`ll take care of the plant, unless you farm sand.
