Your right dave, Every funder listed is a major herbicide producer I won't deny that but are you saying that these corporations are bribing universities and USDA to document only favorable results?
I support community farming and participate in it on a small degree with local friends/neighbors with vegies from our garden but what do we do to support the masses? I don't think a community farm is going to support Miami or NYC. In 1940 we only had 140m US population and now we have over 300m and our amount of ideal farmland has remained the same. The world population has gone from 2b to just over 7b now. Fortunately farmers have been able to increase yields of corn from about 35 bushels per acre from the 40's to over 150 BPA now mostly from GMO seeds, chemical fertilizers, and herbicide weed control.
CSA's and organic farming are filling a niche' and offering an option to the consumer and that's a great thing. My wife is completely on the organic bandwagon and our grocery bills reflect it. I would say that it increases our expense for groceries by at least 30%. Organic milk is just about double of what normal milk is. If it only marginally cost more to go organic than wouldn't consumer prices reflect that or are organic farmers price gouging for a specialty product? I would think it was to cover their costs.
No, I don't think they are bribing for only favorable results. If a researcher gets a grant, and wants to get another one, and if they are asked to evaluate a very narrow perspective or method, then it's easy to produce a result that makes everyone happy. I don't really trust the USDA as an organization, although I'm sure there are conscientious people there. It is often the case that agencies led by political appointees muzzle the staff or filter the publications to be agreeable with whatever the agency is promoting. It's true in private business also.
There is no doubt in my mind that herbicide treatments, or medications in cattle, or whatever is being tested, can show increased production. That is worth knowing, but it is hardly the entire picture.
What the studies do not address are the side effects of those methods. What harms do they cause or have a potential to cause? Does the researcher even know? Well, probably not because that isn't what the grant is funding. Is there much of anything that happens in a vacuum, that has no result, good, bad or indifferent other than those intended? I think we should assume that there are going to be side effects of the good, neutral and bad varieties. It should not come as a surprise after all.
Too often, for-profit businesses have been guilty of hiding known bad effects, or being ignorant of their probability because that would cost money to know. They do an ice cold calculation: how much can be earned, for how long, versus what are the potential losses.
I once worked for a company that was purchased by Schuller Co. You would know them by the name Johns Manville in the US, who had huge settlements against them for asbestos claims. The Schuller representative pitching the situation to us actually bragged about how they had been able to avoid paying those settlements through long drawn out court actions. If you recall, Johns Manville had internal knowledge of the dangers associated with asbestos well before the issue was publicly acknowledged. I went looking for another job.
The increase in farm production, while the number of farm workers plummeted, is one of those all-American, can do, apple pie stories that farmers can rightfully take some pride in achieving. But who is counting the costs along the way? It has caused a total transformation in our rural lives. It would be about financially impossible for a young person with a yearn to farm to enter the business now as a cold start-up and expect to make a living outside those niche markets, and even then they often rely on a family member with a day job with benefits.
Is it really a good thing that so few people are now employed in farming? Now that the industrial era is on the wane, automation and robots are taking jobs, people are sitting around collecting food stamps. They could be hoeing weeds.

Not really funny, but I have a sense that these things are just happening, being driven in direction that profits someone, while the longer-term side effects or evaluation of the greater good remain un-examined.
Are farmers reaping these profits, did farm income rise along with production in relative terms? Corporate farms seem to be doing okay with the government influence on global markets and the tax-paid subsidies they collect. The Monsanto's are doing just fine financially. The food processing industry is in its heyday. Do you check the ingredients labels at the store? I bet your wife does. You would be amazed at where all high fructose corn syrup shows up.
It is not a popular topic, but the planet is over-populated already. The global population is expected to peak at 9-10 billion around the year 2050. We do not have the input resources or downstream disposal methods to support that and maintain a good quality of life.
What we are doing now is adjusting our values to accommodate over population. More people equals more government, more regulation and less freedom. Just about any problem we look at could be avoided or improved by having fewer people on the planet. Water resources, land use, energy, air quality, traffic congestion, war and strife--these are all driven by population numbers.
We are continually nibbling away at our quality of life to compensate for the presence of more people. Put in the context of farming, it means we accept adding rivers of chemicals to the resource stream, growing patented GM plants, and turning food animals into petri dishes because we need the food and the export profits. If we were not being driven to do that, would you say it is a good thing? Would you choose those things if given a choice?
