A vegetation effect calculation device includes: a memory configured to store instructions; and at least one processor configured to execute the instructions to: acquire a moisture content of a slope, a relational expression between the moisture content and an adhesion of soil in the slope, and a vegetation adhesion that is an adhesion of vegetation abundantly growing in the slope; calculate a correction value, using the acquired moisture content of the slope, and the acquired relational expression between the moisture content and the adhesion of the soil; and calculate a corrected vegetation adhesion, using the acquired vegetation adhesion, and the calculated correction value.

Systems and methods for generating agronomic yield maps from field health imagery maps are described herein. In an embodiment, an agricultural intelligence computer system receives a field health imagery map for a particular agronomic field. The system additional receives data describing a total harvested mass of a crop on the particular agronomic field. The system computes an average yield for the plurality of locations on the particular agronomic field. Using the field health imagery map, the system generates a spatial distribution of agronomic yield based, at least in part, on the average yield. The system then generates a yield map using the spatial distribution of agronomic yield.

A method of pollinating a plant: flying an unmanned aerial vehicle above the plant and generating a thrust that contacts the plant, that produces a sound pressure level of at least 610.sup.5 Pascal at the plant, and that produces a frequency that induces the plant to release pollen.

The purpose of the present invention is to provide a mesoionic compound, which exhibits an improved controlling effect on various harmful organisms, or a salt thereof. A mesoionic compound represented by formula (1) (wherein: R.sup.1 is selected from a hydrogen atom, etc.; R.sup.2 represents an optionally substituted phenyl group; R.sup.3 is selected from a hydrogen atom, etc.; R.sup.4 is selected from a hydrogen atom, etc.; R.sup.5 is selected from an optionally substituted ethylene group, etc.; and X is selected from an oxygen atom, etc.) or a salt thereof.

In an embodiment, yield data representing yields of crops that have been harvested from an agricultural field and field characteristics data representing characteristics of the agricultural field is received and used to determine a plurality of management zone delineation options. Each option, of the plurality of management zone delineation options, comprises zone layout data for an option. The plurality of management zone delineation options is determined by: determining a plurality of count values for a management class count; generating, for each count value, a management delineation option by clustering the yield data from and the field characteristics data, assigning zones to clusters, and including the zones in a management zone delineation option. One or more options from the plurality of management zone delineation options are selected and used to determine one or more planting plans. A graphical representation of the options and the planting plans is displayed for a user.
