Use of NPK fertilizers in China peaked in 2015.
Most developing countries tend to subsidize overused fertilizers for the Green Revolution, then tax them when the program is over.
Less pollution, smarter farming, different practices... without reducing yield.

The main product LLM companies offer these days is access to their models via an API, and the key question that will determine the profitability they can enjoy is the inference cost structure.
