12.1.2(i) NUTRIENT MANAGEMENT

Description

Quick Overview

Nutrient management explores how plants acquire essential nutrients for growth and the various methods to enhance soil fertility and crop yields.

Standard

This section emphasizes the significance of nutrients in crop production, differentiating between macro and micro-nutrients, and discusses methods of nutrient provision through manures and fertilizers. It also highlights the importance of sustainable practices in agriculture to optimize nutrient use while protecting the environment.

Detailed

Nutrient Management

Nutrient management is crucial for successful plant growth, as plants require various nutrients obtained from air, water, and soil. Key nutrients are classified as macro-nutrients (needed in larger amounts, such as nitrogen, phosphorus, and potassium) and micro-nutrients (required in smaller quantities, like iron and zinc). This section highlights how these nutrients are delivered to plants through manures, which enrich the soil organically, and fertilizers, which are commercially produced to provide specific nutrients quickly. Sustainable practices are essential to prevent environmental degradation from excessive fertilizer use, and methods like composting and crop rotation can enhance nutrient availability while maintaining soil health.

Key Concepts

  • Nutrient Management: Essential for plant growth, involving the provision of necessary nutrients.

  • Macro-nutrients: Key nutrients required in larger amounts for healthy plant development.

  • Micro-nutrients: Essential nutrients needed in smaller quantities for various physiological processes.

  • Composting: An organic method to improve soil health by recycling organic waste.

  • Sustainable Practices: Practices that help maintain soil fertility without causing environmental harm.
