First national maps of pesticide and fertiliser use

Enjoy:

Apparently England and Wales are one country

A bit confusing, by 'rates' I think they mean amount applied over a given area, not low med and high doses typical of each application?

Apparently base don crop area - CEH has combined the data with county-level information from official government surveys that estimate average rates of pesticide and fertiliser use per hectare for each crop.

Seems to be based on crop area and average pesticide application associated with those crops, presumably from CRD surveys of pesticide use - This has enabled modelling for individual 1km by 1km squares, with estimates for annual usage, in kilogrammes, of each of the three main types of manufactured fertilisers – nitrogen, phosphorous and potassium – and about 130 different types of pesticides including glyphosate and metaldehyde.

Congratulations to the Centre for Ecology and Hydrology, for discovering that there is a correlation between land use and chemical application , and being able to illustrate their vague findings with crayons. And all for only several million pounds. #winning

I like to try and tie each little dot on the map to a TFF member...

While I like the idea:

CEH has combined the data with county-level information from official government surveys that estimate average rates of pesticide and fertiliser use per hectare for each crop.

so this just really shows the density of farmland in a catchment. Not whether those actual farms are high or low level. Its a map based on average uses.

The scary side of big data which hides and accuses all sorts of things
