Kaushal Vikas Class 9 Chapter 3, Precision Farming, introduces technology-driven farming. It opens with a remote-sensing crop health map from satellite or drone imagery, where green shows healthy crop zones and red marks stressed areas so farmers can target water, nutrients and pest control accurately.
What Kaushal Vikas Chapter 3 Covers
Setting Up a School Precision Farming Unit (3.2–3.7) covers process charts, collecting weather data, designing the field layout, selecting tools and materials, and preparing a Bill of Materials.
Humidity Chamber, Low-Tunnel and Drip Irrigation (3.8) gives step-by-step instructions to build a humidity chamber for healthy nursery seedlings, construct a low-tunnel, install a drip irrigation system, and calculate the required quantity of organic fertiliser.
Biofertilisers, Pest Management and Harvesting (3.9–3.13) covers preparing an organic biofertiliser (LAB culture and Trichoderma viride), identifying and managing pests using agro-climatic data, and harvesting and labelling produce.
Controlling the climate: precision farming uses science and technology to raise yield while caring for the environment. Weather data guides how much shade, humidity and protection from rain and wind the plants need. A humidity chamber gives very high, precise moisture and temperature for rooting cuttings and germinating seeds; a low tunnel is larger and less controlled.
Soil and nutrients: the mason-jar test for soil texture and the soil pH test from Chapter 1 decide how much organic fertiliser to add, and the chapter shows how to prepare an organic biofertiliser. A hygrometer measures humidity.

FAQ
What structures do students build in Kaushal Vikas Chapter 3?
A humidity chamber for nursery seedlings, a low-tunnel, and a drip irrigation system in the school precision farming unit.
Which biofertilisers are discussed in Precision Farming?
LAB (Lactic Acid Bacteria) culture and the beneficial fungus Trichoderma viride.
What is the difference between a humidity chamber and a low tunnel?
A humidity chamber is a small structure that keeps moisture and temperature very high and precise for cuttings and germination; a low tunnel is larger and less controlled.
