NCERT Class 9 Skill Education Kaushal Vikas: Chapter 3 — Precision
This chapter introduces Precision Farming, a method that uses science and technology to enhance agricultural yield while protecting the environment. The core principle of precision farming is to provide plants with exactly what they need – the right amount of water, nutrients, and care at the precise time and quantity. It is particularly beneficial for small nurseries with limited resources. Techniques like drip irrigation and sensors, coupled with data-based decision-making, help conserve water, reduce wastage of fertilisers and pesticides, and promote healthier plant growth. The chapter contrasts precision farming with traditional methods, highlighting precise control over climatic parameters, optimized seed sowing with machinery, and advanced nursery management as key features of precision farming.

Vocabulary
| Word | Meaning |
|---|---|
| Precision | Exactly as required and consistent; the same every time. |
| Farming | The activity or business of cultivating land, as to raise crops or rear animals. |
| Remote sensing | The acquisition of information about an object or phenomenon without making physical contact with the object, in contrast to in situ or on-site observation. |
| Agro-climatic | Relating to or characteristic of the climate of a particular region and its influence on agriculture. |
| Drip irrigation | A method of watering plants by delivering water slowly and directly to the roots through a network of pipes and emitters. |
| Sensors | A device that detects or measures a physical property and records, indicates, or otherwise responds to it. |
| Fertilisation | The process of providing nutrients to plants, typically through the application of fertilisers. |
| Pest management | The regulation of pests (in agriculture, forestry, public health, etc.) by using biological, chemical, or physical means. |
| Nurseries | A place where plants are grown for sale or transplanting. |
| Greenhouses | A structure with walls and a roof made chiefly of transparent material, in which plants requiring regulated climatic conditions are grown. |
| Shade-net | A net used to provide shade for plants, regulating light intensity. |
| Meteorological data | Information about the weather and climate. |

Practice questions
- What is the main principle of precision farming? Answer: To give plants exactly what they need, i.e., the right amount of water, nutrients, and care at the right time and in the right amount.
- Name two techniques used in precision farming to save water. Answer: Drip irrigation and sensors.
- How does precision farming help in reducing the use of fertilisers and pesticides? Answer: By making data-based decisions, farmers can apply fertilisers and pesticides precisely where and when needed, avoiding excess use.
- What does the colour red indicate on the 'health map' in Figure 3.1? Answer: Red indicates that the crops are in poor health.
- Give an example of precision farming mentioned in the text. Answer: Greenhouses and shade-nets are examples of precision farming.
Frequently asked questions
What is precision farming?
Precision farming is a method that uses science and technology to improve agricultural yield while caring for the environment by providing plants with exactly what they need at the right time and in the right amount.
Why is precision farming useful in small nurseries?
It is useful in small nurseries because space and resources are limited, and precision techniques help optimize their use.
What are some technologies used in precision farming?
Technologies like drip irrigation, sensors, remote sensing (satellite or drone imagery), greenhouses, and shade-nets are used.
How does precision farming help the environment?
It helps the environment by reducing the wastage of water, fertilisers, and pesticides, and by promoting healthier plant growth with less chemical intervention.
What does a 'health map' in precision farming show?
A health map, often created using remote sensing, shows the health of crops in different areas of a field, using colours to indicate the level of health (e.g., red for poor, green for good).
What is the difference between traditional and precision farming regarding seed sowing?
Traditional farming uses broadcasting or manual tools for sowing, while precision farming uses machinery for sowing seeds at proper spacing and depth, along with modern nursery management techniques.
