Long weights in emergency rooms and for appointments with many specialists seem to top the list of health concerns in Canada. With our aging population, the public cost keeps rising. But I don't hear complaints about rich people benefitting. Living costs rank as our bigger public concern right now.

Not complaining. I prefer the Cdn system. But we still pay some of those higher costs - in our case to public administrators. And many costs here are not covered by public programs. No utopia.

Global Greenhouse Gas (GHG) emissions continue to grow, across all GHGs (CO2, CH4, N2O, F-gas). The only glimmer of light is that CO2 emissions from LUC have declined in the last decade, though with a lot of annual variability. essd.copernicus.org/articles/18/...

Like it or not, X/Twitter is where the farmers are, as are those like me who want to communicate directly with them. It has absolutely nothing to do with Elon Musk, Donald Trump or belittling comments from those who've gone elsewhere.

The problem with GMOs is not that there are too many, but that there are too few. Over 40 years after the first genetically modified plant, its nearly impossible to find any GMO fruits or vegetables. Federal regulations are a big reason why, I explain in @houstonchronicle.com buff.ly/YO3LhET

I don't want to seem like a cup of cold water, but what does the "may" in the abstract tell us? Would " may not" be as truthful? A probability estimate would be far more meaningful, IMHO. Does "may" mean 5% chance, or 50%+?

Just read the underlying study. It 1) does not say “modern agriculture is collapsing,” 2) acknowledges need for 35-56% more food by 2050 without further land clearance, 3) says labor needs in traditional systems are 10x higher, 4) says crop yields in highly agrobiodiverse systems are 20-40% lower.

There are much higher priorities for the use of scarce public funds than "decolonization, and long-term investments in indigenous-led models of health and well- being." Reorienting of priorities at UofGuelph must continue. See, for example, those expressed by @mikeschreiner.bsky.social .

There is still a significant black farming presence near Chatham ON. A good museum at hamlet of North Buxton. This was a recognized northern terminus for Underground Railway, but not as safe from US bounty hunters as more remote areas (like Queen's Bush territory nearer here).

There's a strong Black community in Guelph, blackpastinguelph.com, but I think none remain NW of Kitchener. They got poor treatment when land was surveyed after ~1860. Many moved further north as well as back to the US. That area in Ontario is now dominated by Old Order Mennonites who arrived later.

That Fugitive Slave Act is likely the reason why black immigrants to Ontario often settled (squatted) in 1840-1860, many miles away from the US border - for example, in the as-yet unsurveyed Queen's Bush territory north-west of Kitchener. After US civil war, many returned south.

To each his own. I can't comment on rationale for decisions other than my own. But my primary interest in social media is in learning useful information. And for applied agriculture, Twitter/X is still the best IMHO. I still need Bluesky, however, so I can follow you. 😊 LinkedIn is useful too.

There's ample garbage on both X and Bluesky. I counter by choosing carefully who to follow. A smaller List helps too. The above stated, X is a much better source of practical information on farm techology. I don't see that changing soon. I follow Bluesky too, mainly for more academic perspectives.

If the agricultural community, at least commercially oriented agriculture, is mostly on X, why would you want to leave it? There is no good reason why you can't be on both X and Bluesky.

Your comment may be more relevant to Europe. There is lots of research on GM technology, at least for principal crops, in the Americas, though it's largely in the private sector (where the need for quick research papers is far less significant).

I agree with this thread completely, and get frustrated when "good" scientists, including in agriculture, say that they are collecting data to show that something is true. Worse is when they persist in claiming something remains true when their experimental data show the reverse.

A major farm supply chain shut down recently in Canada and there aren't good alternatives yet nearby. Surprisingly, I can get what I need usually, quickly, and at a reasonable price, from Amazon on-line. One problem is that returns are more complicated with Amazon than with a local retail store.

There is some planting of dry beans after 1st-cut forages here too. Beans are commonly not planted in Ontario until early June, and harvested in early-to-mid September. Almost no no-till beans here; most growers inter-row cultivate to help with weed control.

Our beans are Phaseolus vulgaris, used for baked beans and foods like that. Very different from Vicia faba that is scarely grown in Eastern Canada. I grew these beans for 35 yrs - good for farm finances and for planting winter wheat after September bean harvest. Poor N fixers. Poor for soil quality.

It's interesting how the "experts" seem to be divided into two camps. Those who hate ruminant livestock because of methane and lower feed efficiencies. And the soil regenerative gang who insist on the presence of livestock/forages/manure. And not much communication, it seems, between the two.

Not much N fixation with beans. Not a lot of root DM either, and it breaks down quickly. Acidity is not notable factor. Soybeans are much better for N fixation but also poor for SOC. Ontario soils have declined in SOC with more soybean acreage in recent years and fewer cattle (perennial forages).

Terry Daynard @terrydaynard.bsky.social · 26/09/2025
I grew beans for decades. They were exceptionally poor for soil quality. Even worse than soybeans. Perennial forages are the best, of course, but they require ruminants for utilization. There are no simple answers, only trade-offs.
