Abstract:The water used for agricultural irrigation has significant effects on crop production, along with chemical degradation of soil and water. This study determined the salt dynamics in two irrigation systems for bulb onion cultivation in the Samacá Valley, Colombia. Water samples were taken from the irrigation (reservoir) and the crop with lysimeters. The pH, sodium, potassium, calcium, magnesium, sulfates, chlorides, electrical conductivity (EC), and sodium adsorption ratio (RAS) index were measured. The T-studen… Show more
