Is this what you call the farmers bill?

True there could be an enviromental tax on emissions and by products, you can already only dispose of manure on your own land, you have to pay to have it moved off and get a ticket, and there are nitrate limits for use on land already. The irony being you need manure to keep the fertility and structure of the soil, bagged nitrates are not good for the soil. Everything in farming is already under legal control, from when you can cut your hedge, what you do with your manure, and what you feed your animals.
Its an industry.
If this is the Bill you are talking about, you could look at it two ways, it could be a benchmark to make sure we produce enough of our own food, with quotas/ decisions not dependant on the rest or Europe, or as some think the way in through WTO agreements that food imported does not comply with our welfare and production standards.
If its this Bill its about payments,

which is linked to 'payments for public goods' , when we leave the EU transition period the goverment has agreed it will maintain BPS payments, so needs a legal mechanism to do so, not EU law, but will decide at a later date how these payments will be earned

'There are no details in the Bill of the new Environmental Land Management Scheme expected to form the centrepiece of the new system. Nor does the Bill set out the manner in which direct payments (BPS) will be phased out. An updated policy paper setting out further details is expected to be published during the Bill’s passage.'
Perhaps we will be paid to plant trees.
