Effects of Irrigation Water Quality on the Recovery of 15N- Fertilizer by Sorghum in Field Study
15N-labeled fertilizer was applied to Sorghum at different rates (0, 100 kg N.ha -1 ) to 1m2 microplots and with two kind of water (well water “WW” and treated wastewater “TWW”) to Sorghum grown in field during 1997 and 1999. Increases in DM production, N uptake and 15 NRF were observed with TWW. About 17% and 36% of the 15Nfertilizer were recovered in the crop with TWW in 1997 and 1999, respec...
متن کاملA Variable-Rate Fertilizer Control System for Disc Fertilizer Spreaders
Fertilizer application control in reason is the key technology to improve operation quality, reduce fertilizer pollution, and cut down costs of production. A control system of variable rate fertilizer is developed based on microcontroller chip in the paper. The system can automatically control flow dosage by adjusting feed gate opening size and changing hydraulic motor speed of fertilizer conve...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Integrated Water and Nitrogen Fertilizer Management Using Modeling of System Dynamics Approach in Sugarcane Farmlands with Subsurface Drainage Systems
Using water and fertilizer management at the farm level can be increased water use efficiency and reduce the volume of drainage water, fertilizer losses, and other pollutants in farmland with deep underground drains such as Khuzestan agro-industrial Companies. In the present study, a comprehensive simulation model for the water cycle and the nitrogen dynamics modeling was used for water and fer...
