4 ideas in Class 9 Skill Education, explained in plain words, with games and quizzes to practise.
Health Maps
Part of: Smart farming
Health maps from satellite or drone imagery paint crop condition patch by patch, red flagging worst growth and green crowning best. One sample showed 17 per cent suffering, barely 1 per cent thriving, leaving 82 per cent in between. Farmers read these pictures to aim irrigation, fertiliser and pest control at tiny zones instead of whole fields, saving inputs while lifting yields.
Why it matters. Sky maps target care precisely.

Covered Growing
Part of: Smart farming
Low tunnels arc hoops under polythene sheets, trapping a greenhouse effect that shields crops from cold and nurses summer tomatoes and cucumbers through winter. Humidity chambers hold moist air for nursery seedlings still lacking roots. Growers thus rewrite local climate with shade, extra humidity and guards against rain, wind, frost and fierce sun: greenhouses cool and dry, tunnels warm and shade, chambers humidify.
Why it matters. Covers stretch growing seasons.

Weather Wisdom
Part of: Smart farming
Precision growers log school observatory readings plus Indian Meteorological Department website data, then match conditions to Table 3.4 protections. Agro-climatic records decide whether crops need greenhouse cooling, tunnel warming or chamber misting. Reading skies before sowing turns guesswork into planned shelter and steadier harvests.
Why it matters. Forecasts shield crops early.

LAB Biofertiliser
Part of: Smart farming
Biofertilisers deploy helpful microbes like bacteria, fungi and algae that free nutrients for roots and enrich soil. LAB culture brews wild lactic bacteria from 500 g rice rinse water rested muslin-covered two-thirds full for 3 to 5 still days, then blends one part brew with ten parts milk for another dark 3 to 5 days. Curds part from yellow active liquid, which farmers dilute 1 litre into 9 litres of water and drip onto fields, bottling the rest.
Why it matters. Tiny microbes grow mighty crops.
