👨‍🏭 Spot Spraying

Precision spray technology parameters and costs

Remote Sensing ($/ha)

Cost per hectare for remote sensing and monitoring services. Applied per pass - for example, multiple fallow sprays require a sensing pass for each to locate weeds for targeted spot spraying.

Spot Spray Chemical Savings

Default chemical savings percentages for spot spray systems by task type

System Type	Fallow Spraying (%)	Post-Emergence (%)
GoB (Green on Brown)
GoG (Green on Green)

Chemical savings represent the percentage reduction in herbicide use compared to blanket application. These settings apply to all spot spray systems of each type.

⚙️ Spot Spray System Parameters

Configure cost and performance parameters for different spot spray technology systems. These settings affect spot spray system selection and cost calculations on the Equipment page.

System Name	Type	Fixed Cost ($)	Variable ($/m)	Subscription ($/ha)	Remote Sensing	Actions
