Fertilizers hurt lake’s clarity

To the editor:

In response to a letter from Alvin C. Folks, April 20-22, weather nitrogen fertilizers harm the lake, the simple answer is yes, they do.

As a local landscaper for close to 30 years and born here in the 1950s, I have a longtime love for this body of water. Yes, it is true that nitrogen and phosphates from fertilizers do contribute a great deal to the lack of clarity in our beautiful namesake, Lake Tahoe. Chemical fertilizers, in particular, because of their higher percentage rates of nitrogen and phosphate, accelerate the growth of all living plants and can lead to a toxic buildup in our soil and water.

Natural fertilizers, on the other hand, release more slowly and have a lower percentage rate. But either type of fertilizer may contribute to the growth of algae in this lake, one less quickly.

After reading “And The Waters Turned to Blood,” I contacted the EPA in 1998, about this important issue, with little response. The book documents what fertilizers are doing to our soil and waterways.
