Question
1. Please tell me the advantages of putting sand on turf?
2. I'm a huge advocate of compost & soon a producer of compost. I want to sell compost/sand mix to golf courses, home owners, etc... What would be an ideal mix ratio?
3. What are your thoughts on compost tea?
Thanks, Bill

Answer
Bill:
There are many reasons to apply sand to turf, mostly on the golf course.  I use it to level ground in existing grass.  If drainage needs to be increased, sand can help.
The ratio of sand to organic in greens & tees mix is high.  Handling sand to sell compost is an expensive way to make money.  If you start from handling and trucking sand, it can be profitable.  The key is the USGA (and PGA) contact and approval.
I made compost professionally for many years and was never attracted to golf course mix, except to sell compost to the pros in the field.  For home mix, try a 50/50 to 70/30. sand/compost.  Mostly for leveling and increased drainage.
Do not think much of compost tea.  If high in N or unstable, it stinks and will lose customers.
