Just started a website called CombiCulture.com. The idea behind it is to be a source of knowledge for sustainable agriculture. People can post their stories into the website and classify it by Country, climate, soil, and crop.
So for people in New Zealand of course the country would be New Zealand. Probably the climate would be Oceanic climate (based on the Köppen-Geiger classification Cfb). The soil and crop depends on what you are doing and what area you are.
