TASK  Page No:58

Indian Council of Agricultural Research (ICAR) has launched a mobile-based pest identification and surveillance application named National Pest Surveillance System (NPSS). It uses Artificial Intelligence (AI) and Machine Learning (ML) technology for identification of insect pests in farming. Identify the insects on the plants or those collected in the light trap using the mobile app. 

1. What is their role in the ecosystem? 

Ans: Insects are an essential part of the ecosystem, and we must not eliminate them completely. They play an important role in maintaining environmental health. For example, some insects help in pollination and decomposition, while others act as natural predators to control harmful pests. Therefore, their true value lies in helping us balance crop protection with overall environmental health.

2. What value do they add to the ecosystem? 

Ans: Insects add great value to the ecosystem by improving biodiversity and supporting healthy plant growth. Pollinating insects increase crop production, while decomposer insects help recycle nutrients back into the soil. Beneficial insects also reduce the need for chemical pesticides by naturally controlling pest populations. This helps maintain environmental health and soil fertility.

3. How many of them are pests (harmful for your plants)? 

Ans: Only some insects are harmful to plants. Insects such as aphids, caterpillars, whiteflies, spider mites, and beetles are considered pests because they damage leaves, stems, fruits, and roots. However, many other insects are beneficial and should be protected. Therefore, not all insects collected in the light trap are pests; only a small number may be harmful to crops.

3.13 Assess your learning 

1. Describe the role of digital tools in precision farming. How do they change the way decisions are made on farms? 

Ans: Digital tools play a crucial role in precision farming by shifting farm management from traditional experience-based methods to precise, data-based decisions. 

They change the way decisions are made in several key areas:

(i) Targeted Resource Application: Instead of estimating doses, farmers use data from drones, satellites, and soil analysis to make precise decisions about irrigation, fertilisation, and pest management for small, specific areas of land.

(ii) Automated Environmental Control: Digital sensors (like soil-moisture sensors, hygrometers, and Light Dependent Resistors) automatically make real-time adjustments on the farm. For example, a humidity sensor can automatically trigger a drip irrigation system or a fan, and an LDR can automatically pull down shades if the sun is too bright.

(iii) Optimised Harvesting and Sales: Farmers use apps like Fasal and Kisan Suvidha to track weather updates and market prices, helping them decide the exact optimal time to harvest and how long to store produce for the best market price.

2. Create a safety checklist for the tools you used, including digital tools. 

Ans: Here is a safety checklist for handling various tools and materials are:

(i) Digital Tools (e.g., Hygrometer): Handle carefully as the cover can break, and ensure you do not expose it to excess water.

(ii) Sharp Tools (Hand trowel & Pruning scissors): Do not leave sharp tools lying around; always keep blades closed when not in use and store them safely.

(iii) Measuring Tape: Use a flexible tape to avoid sharp metal edges and store it properly to prevent injury.

(iv) Watering Equipment (Cans/Spray bottles): Maintain a firm grip and avoid spilling water on the floor to prevent slipping hazards.

(v) Protective Gear (Gloves): Always wear gloves when handling soil, compost, or organic media to prevent skin irritation, and wash your hands thoroughly after handling.

(vi) Structural Materials (Bamboo/Metal frames): Ensure that all frames used for tunnels or shade-nets are securely fixed and completely free of sharp edges.

3. During a visit to a precision farming unit, list the key aspects you would observe to understand how precision techniques are applied. 

Ans: When visiting a precision farming unit, you should observe the following key aspects to understand their operations:

Technology use: Identify the specific types of digital tools, sensors, and mobile apps being used to monitor and manage the farm.

Tools and materials used: Take note of the physical materials and tools being used, as well as how they are properly stored.

Key processes: Observe the essential steps involved in their farming cycle and understand the importance of each step.

Schedules: Pay attention to the frequency and timing of key tasks to understand their operational schedule.

Quality criteria: Look at the criteria the farmers use to ensure the quality of their inputs, processes, and final output.

Safety protocols: Notice the safety precautions taken and how appropriately the tools are used.

Expert Insights: You can also ask the farmers or scientists about the specific challenges they face and what they value most about their work, such as the quality of the produce or their earnings.

4. A farmer is using random compost application in one nursery bed and measured compost in another. 

Ans: The bed with the measured compost will likely have much healthier plants. In precision farming, adding the exact required amount of compost is crucial to maintain 1.5% to 2.0% Soil Organic Carbon (SOC). This optimal level makes the soil more porous, enhances its water-holding capacity, and provides energy to beneficial micro-organisms. Random application might lead to a nutrient deficiency or an excess, which does not support consistent, healthy plant growth.
