Fertilizer applications from unmanned aerial vehicles (UAVs) have become increasingly
common in crop farming. With the rise in UAV capacities for payload and batteries, and …

Because of the problems that the current solid organic fertilizer is easy to agglomerate in the
fermentation and stacking process, the fertilizer efficiency is brutal to release, and the strip …

Farmers in China have been concerned with the efficiency and utilization rate of fertilizers,
because of the rigorous implementation of China's “dual-reduction” plan, which calls for …

Experimental testing and calibration of new machines and fertiliser can be costly and time
consuming. Standard centrifugal fertiliser spreaders are designed to achieve a uniform …

Long-term large-scale use of chemical fertilizers will destroy soil fertility, reduce fertilizer
efficiency of chemical fertilizers, and lead to crop yield reduction. The application of organic …

There is no specialized equipment designed to spread granular cylindrical organic fertilizer
in the soil. There are also no rational recommendations available on how to spread this type …

A mathematical model of fertiliser particle motion on a spinning disc is defined and results in
an analytical solution for a concave disc equipped with pitched straight vanes. The ratio of …

A simulation model of a spinning disc fertiliser spreader developed for incorporation into an
automatic control system design is described. Comparisons of the model simulation results …

The particle size range specifications for two biosolids-derived organomineral fertilizers
(OMF) known as OMF 10 (10: 4: 4) and OMF 15 (15: 4: 4) were established. Such …

This paper describes a sensitivity study of the flow of granular fertiliser particles on a
spinning disc using a discrete element model. The aim was to get a qualitative insight in the …
