GRASSLAND

Detect broad-leaved dock and thistles in grassland, with drone analysis.

Problem weeds in grassland are hard to see until they have spread widely. Croptic detects them early, twice a year, before the first cut and after the last cut. So you only treat where the problem is.

Crop info

Broad-leaved dock: start small, end big.

Broad-leaved dock (Rumex obtusifolius) is the most widespread problem species in grassland in the Benelux. One plant produces up to 60,000 seeds per year and spreads via rhizomes. A small patch missed for one season can already cover several square metres by the next spring. Grassland also has two critical detection windows per year: early spring before the first cut, and autumn after the last cut, the moment when the problem weeds are most visible.

TARGET SPECIES

Broad-leaved dock (Rumex obtusifolius), common sorrel (Rumex acetosa), creeping thistle (Cirsium arvense), spear thistle (Cirsium vulgare), creeping buttercup (Ranunculus repens), nettle, couch grass (on reseeded fields).

TWO WINDOWS

Spring (Mar–Apr): problem weeds visible before the first cut, optimal for early intervention. Autumn (Aug–Oct): after the last cut the patches are maximally visible without a crop disturbing the image, an ideal moment for drone detection.

SEASONAL CALENDAR

Two flight windows per season in grassland.

Grassland has no classic crop calendar, but two clear detection windows per year. The autumn window is the most valuable for drone analysis, when the problem weeds are best visible.

How does Croptic detect broad-leaved dock and thistles in grassland?

Step 01

Set field boundaries

Draw in your grassland field on croptic.ai. The drone automatically receives the flight map. For both the spring window and the autumn window.

Step 02

AI detects problem weeds

Broad-leaved dock, thistles and buttercup are recognised on multispectral imagery, even small patches of a few square metres are visible. The map shows every location.

Step 03

Targeted treatment

With the task map your sprayer only drives over the spots with weeds. The rest of the grassland stays untouched. Fewer chemicals, healthier grass stand.

CONTEXT

Intervening early costs less than repairing later.

Broad-leaved dock spreads extremely fast. One plant produces up to 60,000 seeds per year and has an extensive root system that cannot be pulled out completely. Whoever skips a patch for one season already has many times the area to treat by the next spring. Drone detection makes early intervention scalable, without having to walk the whole field.

Fewer chemicals. Healthier grassland.

Frequently asked questions about Croptic in grassland

Yes. Broad-leaved dock is one of the most common problem weeds in grassland and is recognised on multispectral drone imagery. The detection map shows every patch, including small emerging spots.
