    Worth watching. Be sure to send links to all your Tree Hugging friends. U of F released a similar finding in response to Local County Tree hugger ordinances here in Florida. The U of F's take was same, No Fert Laws were causing more damage than proper fertilization.

    Very interesting. I'm book marking this and saving it in case I need it for reference.

    Even more interesting was the fact that they are using a

    I think I'll sit back and watch the debate roll on.

    Thanks for posting.

    Thank you Ric. Confirms what I have observed over the years. Starved lawns contribute to more water and soil runoff vs a well fed lawn.

    absolutely interesting.

    makes total sense and wonder why states did not do research like this before they imposed bans. i think more research is needed in this subject before states should regulate things like this. often times law makers jump the gun and on the bandwagon without having all the facts, and then it becomes law which can sometimes have a negative effect on everyone, but no one is seemingly willing to get it repealed or ammended to correct for wrong information or guidlines

    The law makers in NJ received info like this from the industry, but still passed the strictest fert law in the nation last week. For the past 2 years there was a great deal of negotiations and I believe the bill that passed is a workable compromise. However, when politicians receive 7,000 letters in favor of banning P & only 70 letters opposed, you know what they are going to do.

    I agree with the findings but many people will dismiss the study as biased because it was funded by industry.

    I would have liked to hear them specifically address the P runoff differences of the fertilized plots. Did the "fertilized, but with no phosphorus" plot have the least P runoff after the heavy rain? He said there was a linear relationship of P runoff from the Zero P, 1X P, and 3X P plots.

    But did the Zero P plot have the least P runoff after the rainfall? In other words, I'm asking if the "Zero P" turf was sufficiently dense and developed to provide the least amount of nutrient run off.

    That would be justification for just N and K fertilizing, without additional P.

    Same here. And as far as what Phasthound posted, misinformation coupled with media hype is the root of all evil. That applies to more than just the P debate as well. It's a shame that we can't live in a "no spin" zone.
