  "summary": "Net cost or return of planting a cover crop versus fallow ground.",
  "description": "Cover crops rarely pay back in year one from yield alone; the return usually comes from a bundle of nitrogen credit, reduced erosion, weed suppression, cost-share payments, and grazing value that only shows up when you add them all up. This calculator nets seed, drilling, and termination costs against those offsetting benefits to show whether a given mix pencils out on your operation this year, separate from the longer-term soil health case that takes 3-5 years to show up in organic matter and water-holding capacity. Cost-share through NRCS EQIP or state programs frequently covers $20-45/acre and is often the difference between a cover crop being a net cost or a net positive in year one.",
  "formula": "Net return/acre = (N credit value + grazing value + cost-share − seed cost − termination cost − drilling cost).",

    {
      "q": "How much nitrogen does a legume cover crop actually fix?",
      "a": "A well-established crimson clover or hairy vetch stand can fix 50-150 lb N/acre, but realistic credit for next year's cash crop is usually 30-60 lb because release timing doesn't perfectly match crop uptake. Grass-only covers like cereal rye fix none and can even tie up nitrogen short-term."
    },
    {
      "q": "Does grazing cover crops pay?",
      "a": "Yes, often the single biggest line item. Custom grazing rates or your own cattle's gain value on cover crop forage commonly run $0.50-$1.50 per head per day, and a 60-day graze on decent cover crop tonnage can add $40-80/acre in value."
    },
    {
      "q": "Is cover crop cost-share worth applying for?",
      "a": "Generally yes — EQIP and state programs typically cover a meaningful share of seed and establishment cost for approved species and practices, often turning a marginal year-one cost into a clear net positive without changing your management."
    },
    {
      "q": "What if this shows a negative return?",
      "a": "A negative year-one number doesn't mean skip it — erosion control, weed suppression reducing herbicide cost, and soil health gains that show up in yield 3-5 years out aren't captured here. Treat this as the hard-dollar floor, not the whole picture."
