This group is for discussion of the nutrient requirements for different crops, proper use of fertilisers and soil amendments, soil testing, etc. We aim to collect and share information as to the fertiliser needs of particular crops, to test this and to provide Folians with useful empirical data as to the effects of different fertilisers on crop yields. The group will hopefully also play host to some useful resource threads, such as equivalence between fertiliser products across different countries.

Discussion of organic fertilisers and soil amendments is more than welcome within this group, although it is expected that the majority of the discussion will revolve around commercial chemical fertilisers. (N.B. Over here, it’s “fertiliser”. Over there, it’s “fertilizer”. We won’t criticize your spelling if you don’t criticise ours!)
