The main focus of my recent MLSN discussion was how simple the MLSN guidelines are and how they have helped me simplify my fertilizer use on my golf course. I talked for an hour about how I haven't applied much fertilizer but Micah Woods sums it up in one sentence.
"If your soil tests are above the MLSN guidelines, you can be confident that the grass is supplied with all of that element that it can use."
My talk discussed how there is a lot of fear when it comes to under-fertilizing but we are lucky in that we have the ability to take soil tests so that this doesn't happen. With a test we can confidently make decisions on what nutrient needs to be applied as fertilizer.
Here is my 2015 soil test results.
Which I used to base my fertilizer applications on how much nitrogen I expected to apply.
I was one of the first people to use the MLSN guidelines which I explained in my recent talk and will share in an upcoming post. Since then the experience has been 100% positive. If anything, applying hardly any fertilizer has made my golf course better and certainly hasn't made anything worse. We are always concerned about the consequences of under-fertilizing but I wonder what the consequences of over fertilizing are having?

I also haven't applied a granular fertilizer to my greens in over 3 years. I apply my fertilizer with my sprayer in very small quantities in a relatively high volume of water (2.5gal/1000 or 1000L/ha). I don't think that granular fertilizers are required and if anything they can result in you applying nutrients that aren't needed in your soil leading to waste because you can't change the nutrient ratio in a blended granular fertilizer.
