You can use Florida-friendly fertilizing practices to help protect water quality while having a beautiful lawn. If you fertilize your lawn before a heavy rain, much of the fertilizer will be washed directly into surface water or stormwater systems that drain to our local springs, lakes, rivers and bays.Recent studies have shown that rising nitrate levels in many local water bodies can be traced to fertilizer.ou can use Florida-friendly fertilizing practices to help protect water quality while having a beautiful lawn.

Another misconception has to do with what makes something chemical or physical. Physical sunscreens contain zinc oxide or titanium dioxide, and chemical sunscreens contain micronized ingredients like avobenzone, Dr. Day explains. As for the belief that natural, physical sunscreens are the ultimate way to go? People think that if it's natural rather than chemical, it means it's better.
Oh, let me count the ways: 1  Most sunscreen ingredients protect skin only from UVB or UVA rays. 2  Chemical sunscreens work by transform UV rays into a less damaging form of energy (heat). 3  Chemical sunscreens need to be applied to bare skin for the reaction that makes them work to occur (that takes about 30 minutes). Because zinc oxide creates a barrier on the skin, it can be applied after your moisturizer and 5 minutes before heading out the door. It works immediately.
