Hi. I found a product at the Garden store that was an incredible bargin. The product is fertilizer with the values 25-3-10 (for Nitrogen-Phosphorus-Potasium). I was going ot go with Scotts but they are too expensive. I notice the Potasium in this product is a little higher than normal which is good for protecting against drought and disease (e.g. in hot summers and Fall/Winter). Here is a PDF of this products tech specs straight from the manufacturers website: http://www.nu-groturf.com/specsheets/ProTurf/english/SPEC_4838501_E.pdf Can someone tell me is this good to use on my grass lawn. And even MORE iMPORTANTLY can someone tell me what value i should set my rotary spreader for fertilizing my lawn (my spreader only has values from 1-10 which is standard for most spreaders but noticed this product didnt mention what value). Thanks
