This also highlights why the fert ban is misguided and is making the problem worse.
St. Aug is most active and most able to take up nutrients in the summer. U FL research has shown that proper application technique and proper fert rates in the summer DECREASE nutrient runoff into the waterways and aquifers by creating healthier grass plants and creating healthier roots to act as a filter to nutrient and water runoff.
However, the current fert bans decrease the grass's filtration ability and encourage fert application when the turf can not take up the nutrients as effectively.
The result: increased nutrient runoff and algal blooms!
