AI Agronomy Tool: 4 Tests It Knows Your Field
Most evaluations of farm advisory software test whether the answer sounds correct. That is the wrong test. The better one is whether the answer changes when the field changes. This is a four-part buyer's test an agronomist can run in an afternoon, using questions where local conditions must move the number, plus a worked example showing what a generic recommendation costs per hectare.
Index Insurance vs Indemnity: Which Pays Your Loss?
Two crop insurance designs answer the same question in opposite ways. Indemnity insurance pays after an adjuster measures the loss on your field. Index insurance pays when rainfall, area yield or satellite data crosses a threshold, whatever happened on your land. One is accurate and slow; the other is fast and approximate. This guide shows exactly how each triggers, what proof each demands, and which losses each one actually covers.
Raising Pigs Efficiently, From Piglet to Market Weight
Feed is roughly two-thirds of the cost of producing a pig, so most farms watch feed conversion in the growing barn. That is the wrong number. The ratio that decides profit is whole-farm: every kilogram of feed the operation buys, divided by every kilogram of live weight it sells. Here is what trial data from Europe, the Americas and Asia says about what actually moves it.
Raising Healthy Beef Cattle: What Drives Weight Gain
Cattle usually stop gaining weight while the paddock still looks full. The limit is rarely the amount of grass standing in front of them — it is whether that grass still carries enough nitrogen to keep the rumen working. That distinction reorders almost every decision in a beef enterprise, and it explains why the finishing date is set in the worst season of the year rather than the best one.
How to Increase Milk Production in Dairy Cows
Most advice on raising milk yield starts with the ration. The measured evidence points somewhere else: to dry matter intake, and to the four things that quietly limit it — feed delivery, water, heat load, and the weeks around calving. This guide ranks the feeding and health practices by their documented effect on yield, with figures from Kenya, Brazil and North America, and one worked example.
On-Farm Research Trial Design: Is the Yield Gain Real?
A four-bushel yield gain is the most common claim in on-farm research and the hardest to defend. Most trials that report a 3–5% difference cannot statistically distinguish it from background field variation. This guide covers the replication math, strip width constraints, and yield monitor cleaning steps that decide whether your result holds up — and explains why the fix is usually more fields, not more strips.
How to Grow Onions: Bulb Size and Storage Life
An onion does not decide when to start forming a bulb. Daylength decides for it, on a date the farmer cannot move. That single fact splits the onion season into two halves with two different jobs: everything before that date sets how large the bulb can become, and everything after it sets how long the bulb will keep. Here is what field trials from New Zealand, Portugal, Argentina, India and the United States show about each half.
Soil Test Interpretation: Why Labs Disagree on P Rates
Two laboratories can receive the same soil sample and return phosphorus recommendations that differ by more than 50 kilograms of P₂O₅ per hectare. Neither is wrong. The difference comes from three separate decisions layered on top of the measurement: which chemical extractant was used, which calibration philosophy the system follows, and which yield assumption sets the maintenance rate.
Rice Water Management by Growth Stage: Yield and Quality
Rice tolerates repeated drying for much of its life. What it does not tolerate is drying too deep, or drying at two specific moments. A 2017 UC Davis meta-analysis found the same irrigation practice either cost nothing or cost more than a fifth of the crop, depending on one soil-moisture threshold. Here is what each growth stage demands, and where yield and milling quality part ways.
