The $42–44B herbicide market is growing at 5–6% CAGR even as 546 resistance cases (IHRWD) and tightening regulation expose its limits. Precision spot-spraying has crossed the chasm; robotics works in specialty crops but unit economics are brutal; RNAi remains pre-commercial after 14 years. Here is the science, the capital, the policy, and what soil-health practitioners should do now.
PLFA is the most reproducible method for measuring living microbial biomass in soil — but no validated thresholds exist for interpreting the numbers. Here is what the science actually supports.
Mid-infrared spectroscopy can estimate many soil health indicators from one rapid scan, reducing cost and turnaround while making large-scale, routine field monitoring far more practical.
Cover crops cost water — that much is true. But whether that cost kills your next wheat crop depends on rainfall zone, termination timing, and rotation type, not on a blanket rule. This article works through the actual trade-off numbers for dryland grain and wheat-fallow systems so you can make the call for your operation.
Part 4 of Understanding & Interpreting Soil Health Indicators: what Potentially Mineralizable Nitrogen (PMN) measures, the first-order mineralization kinetics behind it, how the lab runs the 7-day anaerobic incubation, how PMN compares to PSNT, ISNT, ACE protein, hot-KCl and the CO2 burst, how to sample and handle a fresh-soil-only test, what management moves it, and why it is a useful capacity index but a weak stand-alone fertilizer predictor.
Permanganate-oxidizable carbon (POX-C) is the most popular "active carbon" soil health test for good reason: it's cheap, repeatable, and moves with management faster than total organic carbon. Here's what the number means, how to read it for your soil, what actually shifts it, and the limitations that should keep you from over-interpreting it.
$200 per acre is the headline. The realistic range is $16–$162 per acre depending on CI reduction, sharing percentage, and yield — with $71 per acre as the most defensible middle estimate. Run your own numbers in the embedded calculator, and read the honest math, the documentation burden, and what to do now.
Roller-crimping can reduce glyphosate use, but its success is crop- and region-specific: reliable for soybeans in humid areas, risky for corn, and unsuitable for semi-arid Plains.
The realistic per-acre cost of cover cropping ranges from $15 to $100 — but the break-even math depends on which benefits you capture. Here are the real numbers by region.
Sikkim is 100% organic state in India. 66,000 farmers transforming steep Himalayan slopes into a global standard for soil health and resilient agriculture.
Virtual fencing isn’t automation—it’s timing. In sheep and goats, precise moves protect root recovery, reduce parasite exposure, and keep nutrients cycling where they belong: in the soil.
Soil microbial communities regulate nutrient cycling, soil structure, and plant stress responses—processes that directly affect crop productivity and yield stability. Microbial inoculants (often marketed as biofertilizers/biostimulants) can improve crop performance, but their efficacy is highly variable because establishment and function depend on environmental and biological context.
In 2020, while working on soil health in Nebraska, one question kept breaking every conversation: how do we know a practice is improving soil health and compared to what?
