Re: Fertilizer

Stewart,
   When you have a number like 10-10-10 or 10-30-10, this does not tell you
what sources, the fertiizer came from..... it only means the fertilizer is
10% Nitrogen, 10% Phosphorous, and 10% Potash. You must read the bag or
contact the manufacturer to find out what chemicals were used to get the
numbers on the bag. Water soluble plant foods like Peters or Miracle Gro will
list the ingredients. When you have cold Spring soil, the nitrate form of
Nitrogen is preferred. Most water soluble mixes use a combination of Urea,
Amoniacal and Nitrate Nitrogen in a blend. Common ingredients in water
soluble plant food would be Potassium Nitrate, Urea and Ammonium Phosphate.
It is possible to custom blend your own formula using these ingredients. I
don't usually custom blend , but I will alter a formula with Potassium
Nitrate or Ammonium Phosphate to change the numbers a little. Peters 20-20-20
is a good basic formula that works well.
