Sawdust Amendment in Agricultural and Pasture Soils Can Reduce Iodine Losses

Iodine loss is common in the soil of hilly regions due to higher precipitation rates and steeper slopes. deficiency reduces iodine’s bioavailability fruits vegetables consequently may contribute health complications. However, iodine retention soils after addition selected organic inorganic amendments has not been studied. Therefore, a study was carried out investigate during surface runoff. For this purpose, amendment (namely, sawdust, charcoal, wood ash, lime or gypsum) applied separately pasture agricultural under natural rainfall conditions. The fertigated with form potassium iodide (KI) at rate 200 ppm. Surface runoff related properties. Results showed that content linearly pH (R2 = 0.89, p < 0.05) inversely carbon ?0.76, 0.05). Soils amended sawdust had significantly reduced A amount lost via from amendment. Soil were varied for order > charcoal ash gypsum. results indicated amendments, especially improved properties increased capacity soils.
