How it works

The field is a mesh of crop cells, each rendered as a column whose height is its yield (driven by crop health) and whose colour is its soil moisture. A survey drone flies a real boustrophedon (row-by-row) sweep above the canopy, and — exactly like a real multispectral drone pass or fixed IoT sensor network — a cell's moisture is only "known" once the drone has flown over it this pass. Sprinkler droplets fall only on cells that get irrigated this frame, so precision (VRI) and uniform strategies look visibly different: one rains everywhere, the other only where the terrain shows a deficit.

moisture -= evapRate·dt
if VRI:      irrigate cell only if sensed && moisture < threshold
if Uniform:  irrigate every cell
health → target(moisture)   (peaks at the optimal band)
columnHeight = baseHeight + health · yieldScale

Dry threshold — the moisture reading below which VRI decides a column needs water; ignored entirely in uniform mode.
Drone flight speed — how fast the sweep covers the field; a slower flight delays VRI's reaction to a column that just dried out, visible as taller, greener columns lagging behind the flight path.
Irrigation rate — moisture added per watering pass; the falling-droplet particles are denser and taller when this is higher.
Precision vs Uniform — switch strategies and watch the terrain: VRI keeps yield columns tall with droplets falling only on a handful of cells per pass, while uniform mode rains over the whole field every pass for the same or worse average height.

Real-world relevance: the same sense → decide → apply loop drives real variable-rate irrigation controllers fed by soil-moisture sensors and drone or satellite multispectral imagery, cutting water and fertilizer use while holding yield compared with blanket application across a whole field.
