Who owns US farmland? Farmdoc has a new tool to visualize foreign interest in US farmland, created by my colleagues Bruce Sherrick and Juo-Han Tsay at the TIAA Center for Farmland Research. Doing this isn't easy, because the numbers are actually very small.

Foreign Ownership of U.S. Agricultural Land - farmdoc daily

Bruce Sherrick and Juo-Han Tsay - Using US land in Farms as the reference, foreign ownership interests amount to 0.67% of the total, and the remaining 99.33% is US owned. Forestland accounts for…

Recent paper: "There is now overwhelming evidence for the destructive effects of the industrial model of agriculture on Earth’s life-support systems." The fact is that ALL models of crop production that will actually feed us have these destructive effects - it's how crops are grown.

There are a LOT of products out there being marketed to farmers. Many of these products have little to no independent testing to evaluate whether they work. A couple years ago, we tested two products marketed as "soil detoxifiers" - and we found they didn't seem to do anything.

While we may never achieve the goal of complete neutrality in science, it is an essential goal. Science will be worse off if we abandon it. Science: an attempt at neutral disinterest in the results with the goal of finding the truth. Activist science: a motivated effort to prove something is so.

Decades of research said organic farming builds soil better. A study of 3,000 actual farms says: not so fast. It's not organic vs. conventional — it's about biomass inputs, nitrogen, and tillage. The practices matter, not the label. My latest... csanr.wsu.edu/what-actuall...

Dominant Factors: What Actually Builds Soil Organic Matter

Organic and conventional systems can build soil when their practices support the dominant drivers of organic matter.

csanr.wsu.edu

Oh, absolutely. Irrigation is probably the biggest driver of increased SOM for an area like ours. And it can contribute to other issues. But I wish people could see that rather than a strict org/conv binary, proper utilization of best practices from both toolkits is likely to deliver best results.

Organic vs. conventional farming, which builds soil better? A new study of 2,900+ real farms found NO difference in soil organic matter. Why? Because the label doesn't matter — plant biomass inputs, nitrogen, rotation & tillage do. Focus on dominant drivers. csanr.wsu.edu/what-actuall...

China tackles its rural labor crisis with the Honghu T70, an autonomous electric tractor that operates for 6 hours with remarkable precision. A game-changer for agriculture.

Some data from my world: This time last year "Size 60" avocados (most common size) returned about $1.75/ lb to the grower. Today = $1.06. This time last year a gallon of UN32 (conventional nitrogen fertilizer) was about $4.96 Today = $8.54 Not fun.

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.
