The correct answer is: d) All of the above
Organic fertilizers and compost are made from natural materials such as animal manure, plant matter, and composted food scraps. They are a sustainable alternative to synthetic fertilizers, which can pollute the environment. Organic fertilizers and compost improve soil structure by adding organic matter, which helps to hold water and nutrients. They also enhance nutrient content by providing plants with essential minerals such as nitrogen, phosphorus, and potassium. Additionally, organic fertilizers and compost increase water holding capacity by creating a sponge-like effect in the soil. This helps to prevent soil erosion and runoff, and it also ensures that plants have access to water during dry periods.
Here are some additional details about each of the options:
- Improve soil structure: Organic matter helps to improve soil structure by binding soil particles together. This creates a more stable environment for plant roots, and it also helps to improve drainage and aeration.
- Enhance nutrient content: Organic fertilizers and compost provide plants with essential minerals such as nitrogen, phosphorus, and potassium. These minerals are essential for plant growth and development.
- Increase water holding capacity: Organic matter helps to increase water holding capacity by creating a sponge-like effect in the soil. This helps to prevent soil erosion and runoff, and it also ensures that plants have access to water during dry periods.
