Modular precision agriculture system

This invention describes a smart farming machine that moves through crop rows. It has several independent sections, each focusing on a single row. Each section uses sensors to check individual plants, then immediately applies a specific treatment, like fertilizer or pesticide, to that plant *before* the machine moves past it. The sections can also share information with each other and a central unit to coordinate their actions, with the claims specifically highlighting that one section can use data or treatment decisions from another section to decide its own treatment.
