Key Insights

  • 🌱 Manure is prepared through the decomposition of animal excreta and plant wastes by microorganisms like bacteria and fungi.
  • 🌱 It contains organic matter and essential nutrients, providing numerous benefits to soil fertility and plant growth.
  • 🥹 Manure improves soil structure by increasing water holding capacity and aiding drainage.
  • 🗑️ It is environmentally friendly as it recycles waste materials and does not cause pollution.
  • 🗑️ Compost and vermicompost are types of manure obtained from decomposing animal and vegetable wastes using microorganisms and earthworms.
  • 💚 Green manure, obtained from uprooted green plants, enriches the soil with nitrogen and phosphorus.
  • 🎙️ Manure restores and replenishes the nutrients in the soil, compensating for their depletion caused by multiple crop plantings.

Questions & Answers

Q: What is manure and how is it prepared?

Manure is an organic substance that is prepared by decomposing animal excreta and plant wastes. Microorganisms like bacteria and fungi break down these waste materials into simple inorganic substances, which act as important nutrients for plants.

Q: What are the constituents of manure?

Manure consists of organic matter, which is derived from the dead remains of plants and animals. Additionally, it contains nutrients like phosphorus, nitrogen, and sulfur, which are converted from the organic matter by the microorganisms during decomposition.

Q: What is the function of manure in soil?

Manure improves soil structure by increasing its water holding capacity, allowing plants to absorb more water. It also aids in drainage, preventing waterlogging. Furthermore, manure enriches the soil with nutrients, enhancing its fertility and supporting better plant growth.

Q: What are the different types of manure?

The two main types of manure are compost and vermicompost, which are obtained by decomposing animal and vegetable wastes in pits using microorganisms and earthworms. Another type is green manure, which is produced by uprooting green plants and burying them in the soil to provide essential nutrients.

Summary & Key Takeaways

  • Manure is prepared by decomposing animal excreta and plant wastes, which are broken down by microorganisms like bacteria and fungi to form valuable nutrients for plants.

  • Manure consists of organic matter and nutrients, such as phosphorus, nitrogen, and sulfur, which contribute to soil fertility.

  • It improves soil structure by increasing water holding capacity, aiding drainage, and providing essential nutrients for plant growth.
