Re: Lawn fertilizer ok?
K-Mag and Sul-Po-Mag are synonyms. Weights of the products I have here are:
1/2 cup Ammonium Sulfate ~ 113 grams
1/2 cup Sul-Po-Mag ~ 193 grams
1/2 cup Triple 15 ~ 225 grams
In my view the Triple 15 is unnecessary, esp. considering the ideal ratios are 3 lbs of 32-1-48 per year. You could instead apply 1 cup per year of a soil conditioner containing micronutrients; e.g., 3-3-3 and obtain all the phosphorus and minors you need for a year.
