I don't know how they rate your fertilizer in Scotland. Here they rate it
10-10-10, 5-10-10, and so on. The first number is the percent of
nitrogen
content, the second is the phosphate indicator, and I believe the last is
sulfate. The super phosphate I spoke of is 0-46-0 or higher.
Don't put it down until you have confirmed that your soil needs it.

Fert numbers refer to the concentration of N-P-K, the chemical symbols for
nitrogen, phosphorous, and potassium.
