Active soil reaction
Active soil reaction is the measure of the acidity or alkalinity of the soil solution, determined by the concentration of hydrogen ions.

This parameter, typically measured as pH, dictates the solubility and availability of essential nutrients. Monitoring it is crucial for ensuring that fertilizers are actually absorbed by the crop root system rather than being fixed in the soil matrix.
Agronomists assess soil reaction before planting and during fertilization planning. Maintaining the soil in a near-neutral range is vital to prevent nutrient deficiencies and support beneficial microbial activity.
A common mistake is applying fertilizers without adjusting the pH, which often leads to poor nutrient uptake efficiency and wasted input costs. Proper management ensures that elements like phosphorus and micronutrients remain accessible throughout the growing cycle.
