What is soil pH, and why is it important in soil judging?

• A. Measures temperature and effects on soil organisms
• B. Measures moisture and affects plant growth
• C. Measures acidity or alkalinity and affects nutrient availability
• D. Measures compaction state and its impact

Answer: (C)

Soil pH is a critical factor in soil science that measures the acidity or alkalinity of the soil, usually on a scale from 0 to 14, with 7 being neutral. This measure is essential for understanding how well nutrients are available to plants. Different plants have specific pH preferences, and a soil's pH can significantly influence its chemistry, including the solubility of various nutrients. For instance, certain nutrients like iron and manganese may become less available in alkaline soils, while others may become more soluble and potentially toxic in acidic conditions. Understanding soil pH is vital in soil judging since it directly impacts agricultural productivity, gardening practices, and ecosystem health. Proper management of soil pH can lead to optimal plant growth by ensuring that essential nutrients are available in the correct ratios. Adjusting pH through lime or sulfur application is a common practice in agriculture to enhance soil conditions for crops.
