Chris,
We do supplement with fertigation, but typically only during the times that we are overseeded. Traditionally, two of our granular applications also contained Ronstar. This year we blew it in, so no need to combine with a fert application. I think fetigiation is the only true source of controlled release fertilizer, as you control the growth 100%. But, my only negative opinion of fertigation is that once the rains settle in during the summer, we aren't running much irrigation and therefore wouldn't be running any fertigation. We do apply 2-0-12 when we can through the summer, as the granular typically does not include a coated K product. Also, our irrigation system isn't 100% wall to wall, and we have the need to still hit some outer areas with a long-term granular product.
I would love to do a few bio solid apps throughout the year. And although we do use it quite a bit, our members hate the smell. Your program looks to be very solid and consistent. I would still think you would want to put out the organic though to feed the soil and provide a base. The whole idea of the polymer coated products is to reduce labor, and I think they achieve that goal for us. Since fertigation requires minimal labor, I think you are achieving the same goal, just a different way.
