Here is a comment from the: , that disagrees with you on that...

"... If you have very sandy soil (uncommon in the metro area except along South Platte and eastern areas) do not fertilize later than late September, as nitrogen leaches readily through sandy soil, especially during winter months, and will contaminate ground water. On sandy soils, it's best to use "slow-release" nitrogen fertilizers such as organics, IBDU, or sulfur-coated urea, to reduce potential for groundwater contamination..."(emphasis mine)

Haven't heard back from any of my questions... you were telling me what was common sense practices and I was looking forward to a real discussion... is that off now???
Now that I know that clay's texture(platelets) has nothing to do with water infiltration, percolation, or drainage
,,, I wonder what does...
