Building soil P is expensive. The math and the field don’t agree. Just jumped in the combine helping the family farm . Bean yields around here have been pretty good. Can’t speak for everybody, but overall solid. Quality’s a little off. I was listening to a video saying phosphorus needs to be 50 ppm, preferably 100. We just finished a field that made over 60. Around here most APHs are 43 to 45. Mother Nature gets the credit. She did the work. That field tested 3 to 10 ppm phosphorus. Do you really believe another 10, 12, 15 bushel was sitting there just because the soil test number was higher? I ran the math with Grok on building this ground to 50. 11-52-0 at $1,152 a ton is $1.11 a pound of P₂O₅. University data (Iowa State, Minnesota, SDSU, Tri-State) says it takes about 16 to 20 pounds of P₂O₅ to move a Mehlich-3 test 1 ppm. From 5 ppm to 50, that’s roughly $900 an acre on paper. At pH 7.2, calcium ties a lot of that up. Figure 40 percent fixation and you’re closer to $1,500 an acre before you even count crop removal working against you every year. Then ask how many bushels that takes to break even. Chasing that ppm, I’d go broke — or I’d be better off buying more land. We foliar fed this field several times. No check strip, so I can’t prove it paid. I believe it did. Exudation drives phosphorus uptake, stimulation and plant health drives exudation. The more you stimulate the crop, the more phosphorus gets in the plant. - both are important soil P and Uptake. Can’t spend it all just to get it applied to the soil. I’m not anti-phosphorus. I want P in the field. I’m anti-losing money chasing a magical ppm. South Dakota cash beans are about $12.40 tonight. At that price, $1,200 an acre is 97 bushels. $2,000 is 161 bushels. Spread over five years, you need an extra 19 to 32 bushel every single year just to get your money back. Not once. Every year.

Since 2016, California’s Healthy Soils Program has spent $162 million to improve soil health and sequester carbon. 7 field trials of the program's impacts: "short-term impacts on soil health were limited." Are we in the Trough of Disillusionment? californiaagriculture.org/ar…

🌽 Pro Farmer projects U.S. corn yield at 173.2 bpa, well below USDA’s 180.7. PF corn yield has now come in below USDA in 16 of the last 20 Augusts. The 7.5-bushel PF-USDA shortfall is the largest for August in at least 20 years.

Safe to say there is varietal differences in peas 😳
