Answer
Precision agriculture is a farming management approach that observes, measures and responds to variability within and between fields, applying water, nutrients and crop protection only where and when each zone needs them. In India, satellite advisories deliver much of this benefit without per-farm hardware.
Precision Agriculture: a farming management approach that observes, measures and responds to variability within and between fields, so that water, nutrients and crop protection are applied only where and when each zone needs them, instead of uniformly, by the calendar.
It combines soil and microclimate sensing, satellite imagery (NDVI/EVI vegetation indices) and decision models that turn measurements into per-field actions. For Indian farms the payoff shows up as saved water, targeted fertiliser and better-timed sprays.

Yes, when costs are shared: a village-level gateway serving clustered smallholder plots brings per-farm hardware costs down dramatically, and satellite-based advisories need no hardware at all. The margin gains that matter most, water, power and spray savings, scale down to one-acre plots.
Four layers: soil data (moisture, pH, nutrients), microclimate data (temperature, humidity, leaf wetness), crop observation (satellite vegetation indices, scouting) and agronomic models that convert those into irrigation, nutrition and protection decisions.
Smart farming is the broader umbrella, any use of digital technology on a farm. Precision agriculture is specifically about site-specific management: varying inputs across zones of a field based on measured differences.
