**Directions: Read the given passage carefully to answer the following questions.
Each question will have five alternatives as its answer. Choose the correct option as your answer.**
Soil nutrition and organic fertilization are critical components of sustainable agriculture, impacting crop productivity and environmental health. The essence of soil nutrition lies in the soil's ability to supply essential nutrients that plants require for growth, development, and reproduction. Understanding and managing these nutrients sustainably, particularly through organic fertilization, can lead to healthier crops and reduced environmental impact.
Soil is a complex ecosystem teeming with life and is the primary source of nutrients for plants. These nutrients include macronutrients like nitrogen (N), phosphorus (P), and potassium (K), which are required in large amounts, and micronutrients like zinc (Zn) and copper (Cu), needed in smaller quantities but equally vital for plant health. Organic fertilization plays a crucial role in maintaining these nutrient levels without the adverse effects associated with synthetic fertilizers.
Organic fertilizers, derived from natural sources such as compost, manure, bone meal, and green manure, offer a multitude of benefits. These materials contribute not only nutrients but also organic matter, which enhances soil structure, improves water retention, and fosters beneficial microbial activity. The gradual breakdown of organic matter releases nutrients slowly, matching plant uptake and reducing the risk of leaching into water bodies. This slow release also ensures a sustained supply of nutrients over a longer period, supporting crop growth throughout the season.
Moreover, organic fertilization supports the biodiversity of soil organisms by providing food and a healthy environment for worms, fungi, bacteria, and other microbes. These organisms play essential roles in decomposing organic material, fixing nitrogen, and breaking down soil minerals into forms accessible to plants.
Recognizing the benefits of organic methods, many agricultural professionals have begun to pilot new techniques that address the need for sustainable nutrient management. This initiative aims to optimize organic fertilization practices, tailoring them to specific crops and regional soil conditions. By incorporating these practices, farmers can enhance soil fertility naturally, reduce dependence on chemical inputs, and support ecological balance within their farming systems.
Which of the following words is similar in meaning to "pilot" in the context of the passage?

- EOption (e)
Launch
View answer & explanationHide answer & explanation
Correct answer
Experiment
Why this answer is correct
The correct answer is 'Experiment'.
Key Points
- The word 'pilot' as used in the passage refers to the trial or initial implementation of new techniques in organic fertilization.
- For example, the passage mentions "agricultural professionals have begun to pilot new techniques." This context implies testing or trying out something new, which aligns with the meaning of 'Experiment'.
- Let us see the word meanings and usage of the words given in the options:
- Navigate ⇒ to plan and direct the route or course.
- Experiment ⇒ a test or trial to discover something unknown.
- Guide ⇒ to direct or influence the course or direction.
- Control ⇒ to command, direct, or rule.
- Launch ⇒ to start or set in motion.
- From the above discussion, we can see that the word 'Experiment' aligns closely with the use of 'pilot' in the context of the passage.
Hence, the correct answer is Option 2.
