Pattern Assessment of a Spinner Disc Variable-Rate Fertilizer Applicator
Previous work by Fulton et al. (2000) showed the development of a program for generating an “As Applied” map to assess uniform and variable-rate application of potash. The “As Applied” map was created using an “As Applied” file generated during field operation in conjunction with different application patterns determined by Fulton et al. (1999). While modifications are required to improve the p...
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 کاملVariable Rate Application of Potassium Fertilizer for Soybean Crop Growth in a No-till System
Variable rate application of fertilizer has the potential to improve nutrient use efficiency, improve economic returns, and reduce negative environmental impacts. The objective of this study was to evaluate the variable rate application of potassium fertilizer to soybean crop in a no-till system. The study was conducted on a 13-ha soybean grain field in Carambeí, State of Paraná, Brazil in a Ty...

Variable–rate, Spinner–disc Fertilizer Applicator
The popularity of spinner spreaders for application of granular fertilizers and agricultural lime, along with increased interests in variable–rate technology (VRT), has raised concern about application accuracy and distribution of these spreaders. This investigation was undertaken to assess the application distribution of a VRT spinner fertilizer spreader. Application distribution was assessed ...
