Final answer:
The passage details the author's enthusiasm for organic farming methods, focusing on sustainable practices and soil health, hence the correct inference being that the author is interested in organic farming. Organic fertilizers and methods are emphasized for their ecosystem benefits.
Step-by-step explanation:
The passage suggests that the author has a keen interest in organic gardening methods and sustainable agriculture. More specifically, the correct inference from the given options would be C: The author's interest in organic farming is clear in his description. This can be determined from the detailed approach to crop care, emphasizing soil health, responsible water usage, provision of organic nutrients, and the mention of pests' natural controls. There is no information provided about the author being a farmer (A), while the interest in quality vegetables and fruits (B) and attention to crop rotation alone (D) are limited assumptions compared to the comprehensive detail in the excerpt.
Organic fertilizers are preferred over synthetic ones as they are better for the ecosystem. They depend on natural processes to become available to the plants, such as being broken down by decomposers. This slower release contributes to improving the soil texture and water dynamics, vital for successful crop growth and soil health. Organic farming practices also foster biodiversity and ecosystem balance, which can result in healthier crops and, therefore, a more balanced environment.
