I guess this is just old news anymore... :)

At the end of the day you had learned something, which is NEW to you.

Whats new today for this reader and as you said about one fert VS another fert resulting in the same old same is correct.

Any plant nutrient can be a booster if it's in short supply in the soil. Throwing extra nitrogen into the soil can boost green shoot growth when the plant has already used up much of the available nitrogen in the soil.

Plant scientists have been saying it for a long time. Certain substances are limiting in plant growth. If there is a shortage of nitrogen or potassium or calcium, the plant won't grow to its full potential. Plant scientists never said that these nutrients were pixie dust. The correct amount for the plant is enough. More than enough does not help, and at some point begins to hurt. That's all you need to know.

Nutrients may also be leached out of the soil, or be tied up by pH levels. Plants also need certain physical factors, like soil structure. But as far as nutrients go, always make sure the plant has enough of each - then have a cup of coffee. There are no secret ingredients, and more is not better.

Thanks guys for the response. Great addition.

Yes the father of the fertilizer industry! ;)

LOL,

There are alot of secret ingredients. In fact, the secretes are so well kept, I don�t even know one of them. :-(
