What is a technique for enhancing nutrient availability in greenhouse crops?

• A. Utilizing chemical fertilizers exclusively
• B. Regular soil testing and amendment based on needs
• C. Avoiding nutrient source diversification
• D. Using only one type of fertilizer

Answer: (B)

Regular soil testing and amendment based on needs is a fundamental technique for enhancing nutrient availability in greenhouse crops. By testing the soil, growers can determine the existing nutrient levels and identify deficiencies or excesses. This information allows for the precise application of amendments and fertilizers tailored to the specific needs of the plants and the soil conditions. Such targeted interventions help optimize nutrient availability, ensuring that crops receive the essential elements they require for healthy growth and development. On the other hand, relying exclusively on chemical fertilizers can lead to nutrient imbalances and soil degradation over time. Avoiding nutrient source diversification can result in deficiencies of certain nutrients, as plants often require a range of nutrients that might not be provided by a single source. Additionally, using only one type of fertilizer can also contribute to nutrient imbalances, as it may not supply the complete spectrum of nutrients that crops need. In contrast, regular testing and tailored amendments promote a more holistic and effective approach to nutrient management in greenhouse settings.
