FERTILIZER 101
(Answers to your toughest fertilizer questions)
|
Every package of fertilizer gives three numbers, such as 10-10-10. What do these numbers mean?
They indicate how much nitrogen (N), phosphorus (P) and potassium (K) is in that fertilizer. The numbers are percentages of the total package and they are always listed in the same order, N-P-K. A package labeled 10-10-10 will contain 10% nitrogen, 10% phosphorus and 10% potassium by weight.
10-10-10 only adds up to 30%. What else is in there?
Nitrogen, Phosphorus and Potassium are all joined to at least one other element to form a compound. An example would be calcium nitrate which would provide not only nitrogen but also calcium. Synthetic (non-organic) fertilizers are then mixed with something that makes it easier to spread. These are listed on the label as inert ingredients.
How do I know if my soil needs any fertilizer and how much do I add?
To get an accurate evaluation of the nutritional needs of your soil, you will need to have a sample analyzed. Contact your local extension office for testing services. Soil samples can be extremely helpful and remove a lot of the guesswork.
What is the most common mistake in fertilizing?
Without a doubt, over fertilizing is the most common mistake made by beginners and experienced gardeners alike. Just because a little is good, does not mean more is better. It is much better to give to little than too much.
