TranscriptionSegment 21: "Fertilizer Use" Air Date: May 24 ((Anchor Intro)) "If you have a lawn or garden, you know fertilizer can be one of the best tools to use to make your plants grow healthy and green. But if you live around Lake Tahoe or any other water source, you want to be very careful with how much and what kind of fertilizer you use. Shelly Purdy explains in this week's Lake Tahoe Report." ((Take Pkg)) ((Natpop @ 4:24 - pouring water into bottles)) ((Natsot @ 4:34)) "You can see that immediately the granitic soil allows the colored water to flow right through wheras it's much... the composted soil hangs onto the water longer." ((Track 1)) That granitic soil in the bottle on the left is typical of the types of soil found at Lake Tahoe. What's missing in it is the organic material that has been added to the bottle on the right. The granitic soil is extremely porous?and allows water to flow through it much more freely. ((sot @ 4:54)) "If you fertilize on this granitic soul and put too much water on it it will go right past the roots and down into the water table and eventually into the lake." ((Track 2)) That's why the experts recommend that if you do need to use fertilizer on your plants?first add mulch or other organic material to the soil. It will hold the water and make better use of what fertilizer you do apply. Another tip that's especially important here at Lake Tahoe: use fertilizer with little or no phosphorus. That's because the water in Lake Tahoe is extremely rich in nitrogen. When you add phosphorus - like the kind found in fertilizers - it joins with the nitrogen and makes algae grow. ((Sot 12:43 Michael Donahoe ? Sierra Club)) "So if we can keep the phosphorus out of thel ake we have a good chance of saving the lake and keeping it clear." ((Track 3)) So pay close attention to the kind of fertilizers you buy. You might even want to try natural fertilizers like "Dr. Earth" that contain live microorganisms in it which help to break down the nutrients so your plants can absorb them better. And only use as much fertilizer as you need. Using too much just adds to the problem. With the lake tahoe environmental education coalition, I'm shelly purdy for KOLO News Channel 8. ((Anchor Tag)) If you would like more information on fertilizer use or would like to order a complete landscaping guidebook from the University of Nevada Cooperative Extension office, visit our website at In next week's Lake Tahoe Report, Shelly talks about soil conservation and why you should keep your dirt on your property.
