what is the expenditure of U.S. agricultural R&D in 2005?

Question

I want to know the whole expenditure of U.S. agricultural R&D in 2005, all including goverment and private sections.

Answer 1

You'd have to define "agricultural R&D" in a little more detail. For example, would you consider agricultural economics research "agricultural R&D"?

Anyhow, in 2000, the public agricultural R&D expenditure in the U.S. was about $3.8 billion. Data on private agricultural R&D expenditure is hard to come by, but it is estimated that in high-income countries (including the U.S.), private agricultural R&D expenditure accounts for about 55% of total agricultural R&D expenditure. So I would guess that the private agricultural R&D expenditure in the U.S. is about $4.6 billion a year...
