Certified Crop Advisor Practice Exam

Which practice is vital in maintaining soil health in a nutrient management plan?

1. Monocropping

2. Soil testing

3. Excessive tillage

4. Limiting crop diversity

The correct answer is: Soil testing

Soil testing is a critical practice in maintaining soil health within a nutrient management plan because it provides essential information about the nutrient status and overall condition of the soil. Through soil testing, farmers can assess the levels of macronutrients and micronutrients, as well as the soil pH and organic matter content. This data allows for informed decisions regarding the types and amounts of fertilizers and amendments needed to optimize crop production while minimizing the risk of nutrient deficiencies or toxicities. Furthermore, understanding the nutrient profile of the soil helps in promoting sustainable practices that align with environmental conservation. Accurate soil testing informs the timing and application rates of nutrients, thereby enhancing nutrient uptake by crops and reducing losses to the environment, such as nutrient runoff into water bodies. In contrast, practices like monocropping, excessive tillage, and limiting crop diversity can negatively impact soil health. These practices often lead to soil degradation, reduced biodiversity, and loss of organic matter, which can compromise the soil's ability to retain nutrients and support healthy crop growth. Therefore, soil testing is pivotal in a nutrient management plan to ensure sustainable agricultural practices and maintain soil vitality.
