Drone Crop Scouting: What It Sees That Walking Misses
A drone flight shows every square metre of a field at once, so patterns of water stress, nitrogen deficiency and spreading disease appear before a walking scout would cross them. But imagery shows where a field is changing, not why. This guide covers what drones catch earlier, what they miss, the flight settings that make imagery usable, the rules in five regions, and when processing costs are repaid.
Cover Crop Termination Timing: Match the Kill to the Job
Choosing a cover crop and choosing its kill date are one decision, not two. Pick the species for a single job — nitrogen, compaction relief, weed control, or grazing — and that job sets the termination window. Cereal rye usually needs an early kill before maize; hairy vetch gives the most nitrogen when killed late. This guide gives the windows and the cost of a late kill in water and nitrogen.
Fertilizer Use Efficiency: Where Unused N, P and K Go
Cereal crops take up only 35–45% of the nitrogen applied in a season, and 10–25% of the phosphorus. But the missing shares are not the same problem. Most lost nitrogen leaves the field for good, while most "lost" phosphorus stays in the soil for later crops. This guide gives recovery rates by nutrient and crop, traces where the rest goes, and ranks each management lever separately.
Women Farmers’ Access to Credit: Beyond Land Title
Women farmers get less credit mainly because lenders ask for land as collateral, and land titles are usually in men’s names. Lending practices then widen the gap. But women repay as well as men or better. This post separates the structural barrier from the bias, then compares four credit models on repayment and uptake data, with a worked storage-loan example.
When to Terminate Cover Crops: Pick the Job, Then the Date
Most cover crop losses do not come from choosing the wrong species. They come from the right species killed too late, when it keeps using water and nitrogen the next crop needs. This guide matches four common species to four jobs, gives a termination window for each, and shows with real numbers what a late kill costs in stored soil moisture and nitrogen.
Economic Threshold Level: When Spraying Actually Pays
Most published spray thresholds are quoted as if they were biological facts. They are price ratios. This guide gives the action thresholds for the major pests of maize, rice, cotton and vegetables, the scouting protocol behind a count you can act on, and a worked example showing how crop price, spray cost and spray efficacy each move the number you should be spraying at.
Farm Labour Bottlenecks: How to Plan Around Peak Weeks
Most smallholder farms do not run short of labour across the whole season. They run short in two to four specific weeks, and those weeks decide the harvest. This guide gives output per labour day for land preparation, weeding and harvest across hand, animal and mechanised systems. It then shows where the peaks fall by cropping calendar, and what staggering, sequencing and selective mechanisation cost.
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.
