GRANULAR FERTILIZER MASS PREDICTION FOR ELECTRIC FERTILIZER DISTRIBUTION DEVICE BASED ON RANSAC

A 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...

Nitrogenous Fertilizer Plants

Ammonia (NH3) is produced from atmospheric nitrogen and hydrogen from a hydrocarbon source. Natural gas is the most commonly used hydrocarbon feedstock for new plants; other feedstocks that have been used include naphtha, oil, and gasified coal. Natural gas is favored over the other feedstocks from an environmental perspective. Ammonia production from natural gas includes the following processe...

Development of a Stereovision-Based Technique to Measure the Spread Patterns of Granular Fertilizer Spreaders

Centrifugal fertilizer spreaders are by far the most commonly used granular fertilizer spreader type in Europe. Their spread pattern however is error-prone, potentially leading to an undesired distribution of particles in the field and losses out of the field, which is often caused by poor calibration of the spreader for the specific fertilizer used. Due to the large environmental impact of fer...
