Question

Explain briefly giving at least 4 key relevance of organic fertilizers in arable crop production.

A) Enhanced soil fertility, reduced environmental pollution, improved soil structure, increased microbial activity.
B) Increased chemical residue, minimized soil erosion, reduced biodiversity, decreased water retention.
C) Improved pesticide use, accelerated plant growth, higher crop susceptibility, elevated greenhouse gas emissions.
D) Decreased nutrient content, higher costs, diminished soil health, increased soil salinity.

Answer 1

Organic fertilizers have multiple benefits in arable crop production, including enhanced soil fertility, reduced environmental pollution, improved soil structure, and increased microbial activity.

Step-by-step explanation:

Organic fertilizers have several key relevance in arable crop production:

1. Enhanced soil fertility: Organic fertilizers contain a variety of nutrients that promote the growth and health of plants, leading to improved soil fertility.
2. Reduced environmental pollution: Organic fertilizers are derived from natural sources and do not contain harmful chemicals, reducing the risk of pollution to the environment.
3. Improved soil structure: Organic fertilizers help to improve soil structure by increasing organic matter content, which promotes better water and nutrient retention.
4. Increased microbial activity: Organic fertilizers provide a food source for beneficial microorganisms in the soil, promoting their growth and activity, which enhances nutrient cycling and overall soil health.
