Reduced Tillage in an Irrigated Potato Rotation
Soil erosion continues to be a threat to agricultural productivity worldwide, with soil losses in the United States exceeding 3 billion tons annually. Wind and water erosion have caused dramatic declines in soil productivity. Erosion protection and associated conservation of nutrients, organic matter, soil water holding capacity and biota are significant concerns. Pimentel et al. (1995) estimat...
متن کاملSite-Specific Multilevel Modeling of Potato Response to Nitrogen Fertilization
Technologies of precision agriculture, digital soil maps, and meteorological stations provide a minimum data set to guide precision farming operations. However, determining optimal nutrient requirements for potato (Solanum tuberosum L.) crops at subfield scale remains a challenge given specific climatic, edaphic, and managerial conditions. Multilevel modeling can generalize yield response to fe...

متن کاملFertilizer management effects on nitrate leaching and indirect nitrous oxide emissions in irrigated potato production.
Potato ( L.) is a N-intensive crop, with high potential for nitrate (NO) leaching, which can contribute to both water contamination and indirect nitrous oxide (NO) emissions. Two approaches that have been considered for reducing N losses include conventional split application (CSA) of soluble fertilizers and single application of polymer-coated urea (PCU). The objectives of this study were to: ...
متن کاملApproaches of Iranian Medical Universities to Quality Management in Education
Introduction: Universities of medical sciences in Iran have recently employed different quality management approaches according to their own reasoning. They include accreditation, total quality management (TQM), suggestion system, ISO 9000, and productivity. This study aimed to identify chosen approaches in Iranian Medical universities and clarify the reasons of selection as well as practical m...
