Interpreting Soil Test Results

Interpreting soil test results helps you understand the specific needs of your vegetable garden. You can make informed decisions that enhance plant health and improve yields.

Understanding Nutrient Levels

Nutrient levels reveal vital information about the health of your soil. Common nutrients tested include nitrogen (N), phosphorus (P), and potassium (K).

• Nitrogen: Promotes leafy growth. A deficiency shows as yellowing leaves.
• Phosphorus: Supports root development and flowering. A lack of this nutrient results in stunted growth.
• Potassium: Enhances drought resistance and overall plant strength. Insufficient potassium causes browning or wilting of leaf edges.

When your soil test indicates that certain nutrients are low, you can amend it with organic fertilizers, such as compost or bone meal, to restore balance. Regular testing every 2–3 years keeps nutrient levels optimal.

pH Balance

pH balance indicates how acidic or alkaline your soil is, impacting nutrient availability. Most vegetables thrive in a pH range of 6.0 to 7.0.

• Acidic Soil (pH < 6.0): Nutrient deficiencies may occur, especially in calcium and magnesium. Adding lime can help raise pH levels.
