Which practice is NOT part of nutrient management?

Nutrient management is a systematic approach to managing the nutrients in the soil to enhance plant growth and minimize environmental impacts. The first three options—soil testing, crop rotation, and composting organic waste—are practices directly related to the management of nutrients.

Soil testing is critical because it helps determine the nutrient status of the soil and guides the application of fertilizers and amendments to meet the needs of crops. This ensures that nutrients are supplied in the right amounts, thus promoting healthy plant growth and preventing nutrient runoff.

Crop rotation contributes to nutrient management by alternating different types of crops in a specific field over time. This practice can improve soil health, enhance nutrient cycling, and reduce pest and disease pressures. Different crops have varying nutrient requirements, and rotating them can help balance soil nutrient levels.

Composting organic waste is another beneficial practice as it enriches soil with organic matter and essential nutrients. It can enhance soil structure, improve water retention, and provide slow-release nutrients for crops.

In contrast, random pesticide application does not relate to nutrient management. While pest control is vital for maintaining healthy crops, it does not directly involve the management of soil nutrients. Instead, nutrient management focuses on practices that ensure optimal nutrient availability and minimize environmental impacts, rather than random application of
