- What is agriculture?
Answer: Agriculture is the practice of growing crops and raising animals to provide food and other products for human use. - Why do we need to store harvested grains?
Answer: Grains are stored after harvesting to protect them from insects, moisture, and rodents, so they remain safe to eat and use. - What tools are used for tilling the soil?
Answer: Traditional tools like ploughs and modern tools like tractors and cultivators are used for tilling. - Why is leveling of the soil important?
Answer: Leveling prevents water logging and ensures even distribution of water during irrigation. - What are fertilizers and how are they different from manure?
Answer: Fertilizers are chemical substances rich in nutrients, while manure is natural and made from animal or plant waste. - How is sowing done in modern farming?
Answer: Farmers use seed drills for sowing, which places seeds at proper depth and spacing in the soil. - What is irrigation and why is it necessary?
Answer: Irrigation is watering crops regularly, essential for their growth, especially in areas with less rainfall. - Name two modern irrigation methods.
Answer: Two commonly used modern irrigation methods are drip irrigation and sprinkler systems. These techniques help conserve water while ensuring proper watering of crops. - How do weeds affect crops?
Answer: Weeds compete with crops for nutrients, water, and sunlight, which can reduce crop growth and yield. - What are the common methods of removing weeds?
Answer: Weeds can be removed by hand or using tools like khurpi, or by spraying weedicides. - What is harvesting?
Answer: Harvesting is the process of gathering fully grown crops from the fields once they are ready for use. It marks the end of the crop production cycle. - What is threshing?
Answer: Threshing is separating grains from the harvested crop plants. - How is harvesting done in large farms?
Answer: Machines like harvesters and combine harvesters are used for quick and efficient harvesting. - What is crop rotation?
Answer: Crop rotation refers to the practice of planting different types of crops in the same field across various seasons. This helps preserve soil nutrients and improves soil fertility over time. - What is the purpose of storing grains?
Answer: Proper storage keeps grains dry and safe from pests, so they can be used throughout the year. - What are rabi crops?
Answer: Rabi crops are sown during the winter months and harvested in the spring season. Common examples include wheat and gram. - What are kharif crops?
Answer: Kharif crops are cultivated during the monsoon or rainy season. Popular examples are rice and maize. - Why is it important to manage crop production?
Answer: Managing crop production ensures better food supply, healthier crops, and efficient use of resources.

Source:
- Manures are natural substances made from decomposed plant and animal waste.
- Fertilisers are man-made chemical substances.
Nutrient Content:
- Manures have low and variable nutrient content.
- Fertilisers are rich in specific nutrients like nitrogen, phosphorus, or potassium.
Effect on Soil:
- Manures improve soil structure and increase organic matter.
- Fertilisers do not improve soil texture and may harm soil health if overused.
Cost and Usage:
- Manures are cheaper and eco-friendly but work slowly.
- Fertilisers act quickly and are more expensive.
