Horizontal matter fluxes and leaching losses in urban and peri-urban agriculture of Kabul, Afghanistan



Horizontal matter fluxes and leaching losses in urban and peri-urban agriculture of Kabul, Afghanistan



Journal of Plant Nutrition and Soil Science 174(6): 942-951



Little is known about nutrient fluxes and nutrient-use efficiencies in urban and peri-urban agriculture (UPA) of rapidly expanding cities in developing countries. Therefore, horizontal flows of carbon (C), nitrogen (N), phosphorus (P), and potassium (K) as well as leaching losses of mineral N and P were measured over 2 years in three representative agricultural production systems of Kabul. These comprised 21 gardens and 18 fields dedicated to vegetable farming, cereal farming, and table-grape production (vineyards). Across sites (fields and gardens) biennial inputs averaged 375?kg N ha 1, 155?kg P ha 1, 145?kg K ha 1, and 15?kg C ha 1 while with harvests 35?kg N ha 1, 4?kg P ha 1, 33?kg K ha 1, and 7?kg C ha 1 were removed. In vegetable gardens, biennial net balances were 8?kg N ha 1, 75?kg P ha 1, 25?kg K ha 1, and 4?kg C ha 1, whereas in cereal farming biennial horizontal balances amounted to 155?kg N ha 1, 2?kg P ha 1, 355?kg K ha 1, and 5?kg C ha In vineyards, corresponding values were 295?kg N ha 1, 235?kg P ha 1, 5?kg K ha 1, and 3?kg C ha Annual leaching losses in two selected vegetable gardens varied from 7 to 25?kg N ha 1 and from 5 to 1?kg P ha Night soil and irrigation water were the major sources among the applied nutrient inputs in all studied farming systems, contributing on average 12% and 25% to total N, 22% and 12% to total P, 41% and 53% to total K, and 79% and 1% to total C, respectively. The results suggest that soils in extensive cereal fields are at risk of N and K depletion and in vegetable gardens of K depletion, while vineyards may be oversupplied with nutrients possibly contributing to groundwater contamination. This merits verification.
