Well, ok, I can be a bit more specific if required.
In England (and Wales too I think?) the SFP, for one more year, is now a relatively simple area-related payment. There is now no historical headage element, that has been phased out over the life of the current scheme.
Different types of land attract different rates of payment.
(In order to use up lots of money paying bureaucrats when the sheme is now 'relatively simple', the bureaucrats make the maps as wrong as possible, change them all the time, recategorise land all the time...)
Over and above SFP, which is a currently an entitlement for all farmers / landowners who can meet some basic requirements to maintain the land in good agricultural heart, there are various other schemes where monies can be allocated either as grants for specific projects and/or as annual payments against a usually 5- or 10-year contractual agreement to farm specific pieces of land in specific ways, usually to render environmental or other benefits.
Some of these include Countryside Stewardship, CSS; Entry-Level Environmental Stewardship, ELS; Higher-Level Environmental Stewardship, HLS; Uplands Environmental Stewardship, UELS; Organic Entry-Level Environmental Stewardship, OELS.
The current SFP scheme runs out next year. At the moment we are not sure what it will be replaced with, but it seems relatively certain there will be more environmental commitments required in order to claim it.
