I am not going to bring out the SOIL SAMPLE Flag because I haven't pulled a soil sample in Years. But I know what my soil is and has or doesn't have that I need to add. I am sure my Fert program wouldn't work in other areas as good as it does in my area.
My soils vary greatly from sandy to clay/rock. I have been on a granular only program due to limited time and have had good success with choosing higher quality products. I am considering a liquid or hybrid program for customers who desire the ultimate and are willing to pay. 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?
