What are the important ccp that can be measured by soil analysis

Soil pH is a critical factor because it directly affects the availability of nutrients to plants. Most crops thrive within a specific pH range (e.g., 6.0-7.0). Deviations can lead to nutrient deficiencies or toxicities. Soil analysis measures pH to determine if adjustments (like liming or adding sulfur) are needed to optimize nutrient uptake.

Soil salinity, measured as Electrical Conductivity (EC), indicates the concentration of soluble salts in the soil. High salinity can reduce a plant's ability to absorb water, leading to water stress and reduced yields. Monitoring EC through soil analysis is crucial, especially in irrigated agriculture, to prevent salt buildup that can harm crops.

The levels of essential plant nutrients like nitrogen (N), phosphorus (P), potassium (K), and micronutrients are CCPs. Soil analysis quantifies these levels, allowing for precise fertilizer application. Imbalances (too little or too much) can severely impact crop growth and yield, and excess nutrients can leach into groundwater, affecting water quality.
