Gaseous and leaching losses of carbon and nitrogen in irrigated organic farming of a coastal oasis in Oman

"Little experimental data exist regarding direct application of manure in irrigated subtropical organic cropping systems. While effects of manure quality on crop growth are well documented for temperate regions, such data are scarce for the arid tropics and subtropics. Therefore effects of different carbon/nitrogen (C/N) ratios and different ratios of structural/soluble carbohydrates (NDF/SC) in manure applied to irrigated organically grown vegetables were investigated during a two years field experiment in Sohar, northern Oman."
