The North Bosque watershed

Hamilton County is one of four counties covered by Texas's North Bosque River phosphorus limits, adopted in 2001, and the river runs through Hico. Dairies spread manure on hay and forage ground across the watershed. Drone application fits that ground: low-volume, targeted passes, no wheel traffic on wet fields and mapped buffers along streams and stock tanks.

Cedar brakes: Ashe and redberry juniper

"Cedar brake" is the local word for a juniper thicket, and Hamilton County has both kinds:

• Ashe juniper doesn't resprout once it's top-killed, so small trees are cheap to remove by fire, cutting or spot treatment.
• Redberry juniper resprouts from the root collar, so it's harder to control with fire and is best treated while small.

Drones spot-treat young trees from mapped coordinates and keep spray off pecans and live oaks.

Mesquite: two spray windows

1. Soil temperature: at least 75°F at 12–18 inches, better above 80°F, with spraying within 60 days of reaching it.
2. First window: 42–63 days after bud break, usually late May to mid-June, when leaves are dark green.
3. Second window: 72–84 days after bud break, usually the first half of July, as beans mature.
4. Skip it if: new light-green growth shows at the tips, or more than 25% of foliage is damaged.

Broadcast passes need at least 4 gallons per acre total spray.

Prickly pear

AgriLife Brush Busters treats scattered prickly pear plant by plant, with pad sprays killing more than 7 of 10 plants. Heavy stands call for broadcast treatment, often followed by spot work on survivors a few years later. A drone does both from the same field map.

Hay pests

Fall armyworm: treat at 3 or more per square foot, scouting in the morning and spraying the same day.

Bermudagrass stem maggot: in Texas since 2012. Scout 50 stems at 5–10 spots. At a $12 treatment cost, the threshold is about 16% damaged stems for $140-per-ton hay and 22% for $100 hay. If damage is heavy, cut, then spray a pyrethroid 7–10 days after cutting.

Rolling prairie and limestone valleys

Field condition	Tractor sprayer	Spray drone
Rocky limestone slopes	Tire damage	No ground contact
Leon and Bosque bottoms after rain	Ruts	Flies from the field edge
Cedar and mesquite thickets	Can't get through	Flies over the canopy
Hay close to cutting	Crushes the stand	No crop contact

The Leon, Lampasas and Bosque rivers cut deep valleys with limestone cliffs across the county. Operators map streams, stock tanks and homes as no-spray zones and check FieldWatch's DriftWatch and BeeCheck before every job.

Texas licensing and airspace

The Texas Department of Agriculture (TDA) requires a Commercial Applicator license with the Aerial category plus a use category such as Pasture and Rangeland. Hamilton County and its neighbors aren't on TDA's regulated-herbicide list. Fort Cavazos restricted airspace lies to the southeast in Coryell County and doesn't extend over Hamilton County, but operators still check airspace for every field. The FAA requires Part 107, Part 137 and a Section 44807 exemption for drones of 55 pounds or more.
