Phosphorus, farmer perspectives, and nothing.

I guess the geological survey work has been going on for 5+ years, but now it’s a big deal in the news. Let’s use the P wisely.
Farmer perspectives about cover crops by non-adopters (Myers and Wilson 2023)
Non-adopters identified a number of concerns about cover crops, with the top concern being the time to plant and manage cover crops. Approximately 80% of non-adopters reported being open to considering cover crops. Factors cited to encourage non-adopters to adopt cover crops included incentive payments, tax breaks, crop insurance discounts, and soil carbon payments.
Grounding United States policies and programs in soil carbon science: strengths, limitations, and opportunities (Gelardi et al 2023)
Guiding principles for this discussion include the notions that
climate change adaptation must be prioritized alongside climate change mitigation
soil carbon sequestration must be paired with greenhouse gas emission reductions
structural issues and barriers to adoption must be addressed as part of all policies and programs
practice- and place-specific programs must be administered in lieu of one-size-fits-all prescriptions
soil carbon science is not yet sufficiently advanced for the accounting and contractual frameworks proposed in cap-and-trade or regulatory approaches.
Table 1 Visualization tools such as ggplot2, Vega-Lite / Altair, and Observable Plot support an expressive range of visualizations with a concise syntax. However, these tools were not designed to handle millions of data points. Mosaic provides greater scalability by pushing data-heavy computation to a backing DuckDB database. Mosaic improves performance further by caching results and, when possible, performing automatic query optimization.
If you can make it past the 17th requirement, well done.
