Questions and Answers

Why is it important to properly dry freshly harvested grains before storing them?

To reduce moisture and prevent spoilage or attack by organisms

What is the purpose of using neem leaves when storing food grains at home?

To protect the grains from pests like insects and rats

How do large godowns protect stored grains from pests and microorganisms?

By employing specific chemical treatments

What is the difference between fertiliser and manure?

<p>Fertilisers are inorganic substances that provide specific nutrients to plants, while manure is an organic substance obtained from the decomposition of plant or animal wastes that replenishes the soil with a variety of nutrients.</p> Signup and view all the answers

Explain the process of obtaining organic manure.

<p>Organic manure is obtained from the decomposition of plant or animal wastes. Farmers dump plant and animal waste in pits at open places, allowing it to decompose due to the action of microorganisms.</p> Signup and view all the answers

How does continuous cultivation of crops impact soil fertility?

<p>Continuous cultivation of crops depletes the soil of essential nutrients, making it poor in nutrients. Farmers must then add manure to replenish the soil with nutrients through the process of manuring.</p> Signup and view all the answers

How are fertilisers different from manure?

<p>Fertilisers are chemicals rich in a particular nutrient, produced in factories, while manure is organic and improves soil texture and water retaining capacity.</p> Signup and view all the answers

How can the soil be replenished with nutrients through crop rotation?

<p>By growing different crops alternately, farmers can replenish the soil with essential nutrients.</p> Signup and view all the answers

Why are legumes grown as fodder in one season and wheat in the next season in northern India?

<p>Growing legumes as fodder helps replenish the soil with nitrogen, benefiting the subsequent wheat crop.</p> Signup and view all the answers

<p>Excessive use of fertilisers can lead to soil degradation, water pollution, and decreased soil fertility.</p> Signup and view all the answers

Study Notes

Post-Harvest Grain Management

  • Properly drying freshly harvested grains before storing them is crucial to prevent moisture from encouraging the growth of fungi, bacteria, and insects, which can lead to grain spoilage and loss.

Natural Pest Control

  • Neem leaves are used when storing food grains at home because they have natural insecticidal and fungicidal properties that help repel pests and prevent grain spoilage.

Large-Scale Grain Storage

  • Large godowns protect stored grains from pests and microorganisms by using techniques such as fumigation, sealed storage, and regular monitoring to maintain a clean and dry environment.

Soil Amendments

  • Fertilisers are inorganic substances that provide essential nutrients to plants, whereas manure is organic matter derived from animal waste or plant residues that adds nutrients and improves soil structure.

Organic Manure Production

  • Organic manure is obtained through the decomposition of organic matter, such as crop waste, animal waste, or compost, which releases nutrients that can be absorbed by plants.

Soil Fertility

  • Continuous cultivation of crops can lead to soil fertility depletion, as crops absorb nutrients from the soil without replenishing them.
  • Crop rotation is a technique used to replenish soil nutrients by planting legumes, which fix nitrogen, and then planting crops that require nitrogen, such as wheat.

Crop Rotation

  • Legumes are grown as fodder in one season and wheat in the next season in northern India because legumes fix nitrogen, which is then utilized by wheat, reducing the need for fertilisers.

Environmental Impact

  • Excessive use of fertilisers can harm the environment by contaminating water sources, reducing soil fertility, and promoting the growth of unwanted plants, such as weeds and algae.
