Root, Leif, Flower...

Check the acidity/alkalinity of the soil.
Then think...

Root, Leif, Flower...

0-0-0
Is as example much higher numbers may or may not be represented in the product used.

Root veggies ... have a great need for the 0-0-10 last number to be higher

Leif... Needs 10-0-0 for example, or when that is the growing time of the plant before it flowers

Flower...Needs 0-10-0 for the time that comes to set the fruit.

So when the seed to soil a good 10-10-10, but when the food set to type increase the needed equation.

Think of your crops as Root, Leif, Flower...

Root= beet, carrot, radish, potato, you get the idea...
Leif= lettuce, kale, cabbage so on...
Flower= tomato, pepper, beans, berry and so on...

All the while to remember the other balance of 13 essentials. So to ready the soil a 10-10-10- that is balanced in the other 13 essentials.
Each food has a need that it will speak of...Learning to listen is the beginning of understanding. All this knowledge won't do you a bit of good unless you gain the understanding of how to make use of it.

This the great lesson of the spring crop of 2009
