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 ...
متن کاملPattern 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 کاملDevelopment of a Semi-controller for a Variable Rate Fertilizer Applicator
In this paper, aiming at the current development of domestic agricultural production, introduced a variable fertilizer controller which suits for a domestic food-producing areas to promote output. The variable rate fertilization controller combined with the current Chinese made fertilizer equipment; mechanism of metering system for the applicator uses a flute wheel. The amount of fertilizer is ...
متن کاملDevelopment of Variable Rate Fertilizer System Based on Optical Sensor
A variable rate fertilizer system was developed for control of fertilizer amount by optical sensor measured NDVI of crop. The paper analyzes the input and output conditions of control system, and designed hardware, algorithm and control of fertilizer, mainly software flow and a feedback control way. In the paper, the variable-rate control system consisted of 6 optical sensors mounted on a boom ...
