kindly review script

[rhijmans]

Moved to pending because the "eight different environments" do not appear in the standardized data. Can you please improve the script and make a new PR?

Please carefully look at the changes I made so that I do not have to make them again in the future:

• do not quote numbers (e.g. latitude/longitude)
• _Fertilizer cannot be FALSE (it can be 0, or a positive number, or a numeric NA)
• do not retail the comments from the template script
