Abstract

Computer-implemented systems and methods predict behavior of sprays based on receiving a selection of one or more variables affecting spray. Relative amounts of the droplets forming the spray are grouped into various droplet size classes, where each droplet size class represents a range of droplet sizes. The relative amounts of the spray in the classes is visually depicted on a computer display according to a distribution of droplets, a volume of spray falling within the droplet size classes, a chart depicting relative amounts of the spray as a function of droplet size, or according to a spray quality based on environmental factors.

Claims

1. A computer-implemented method for depicting agricultural spray behavior as a spray distribution, the method comprising:

using a computer processor configured to;

receive a selection of an agricultural spray comprising at least one of an active ingredient or an adjuvant;

receive a selection of a spray parameter at which the agricultural spray is to be sprayed;

retrieve analyzed spray particulate data based on the received selections, the retrieved data comprising a distribution of relative amounts of agricultural spray droplets within droplet size classes where each class corresponds to a range of droplet sizes; and

transmitting for graphical display the distribution of the relative amounts of the spray droplets in the droplet size classes;

wherein the spray droplets are displayed as a series of representative droplets, each representative droplet associated with one of the droplet size classes, and

wherein the representative droplets within a droplet size class are displayed with droplet size information.

2. The method of claim 1, wherein the representative droplets within a droplet size class are displayed with droplet size information comprising one or more of the range of droplet sizes represented, drift potential, leaf runoff potential and leaf coverage.

3. The method of claim 1, wherein the representative droplets displayed are arranged within a distribution curve representing a distribution of size of the representative droplets based on the relative amounts.

4. A computer-implemented method for depicting agricultural spray behavior, the method comprising:

using a computer processor configured to;

receive a selection of an agricultural spray comprising at least one of an active ingredient or an adjuvant;

receive a selection of one or more spray parameters at which the agricultural spray is to be sprayed;

retrieve analyzed spray particulate data based on the received selections, the retrieved analysis data comprising relative amounts of agricultural spray droplets within droplet size classes corresponding to a range of droplet sizes; and

transmitting for graphical display the relative amounts of the spray droplets in the droplet size classes,

wherein the calculated relative amounts of the droplets are displayed as a series of representative droplets, each representative droplet associated with one of the droplet size classes, and

wherein the representative droplets within a droplet size class are displayed with droplet size information.

5. The method of claim 4, wherein:

the received selections of the agricultural spray and the one or more spray parameters comprises a set of selections and the computer processor is configured to receive at least two sets of selections; and

the relative amounts of the droplets in the droplet size classes for the sets of selections are relative volumes of the droplets in the droplet size classes and are displayed as a volumetric comparison of the sets of selections.

6. The method of claim 4, wherein:

the received selections of the agricultural spray and the one or more spray parameters comprises a set of selections and the computer processor is configured to receive at least two sets of selections; and

the relative amounts of the droplets within the droplet size classes for the sets of selections are simultaneously displayed as a cumulative distribution chart.

7. The method of claim 4, wherein:

the received spray parameter selections comprise one or more of a boom height and a wind speed; and

transmitting for display the relative amounts of the droplets within the droplet size classes within a plurality of spray quality categories associated with the agricultural spray being sprayed according to the received selections of the one or more of the boom height and wind speed.

8. A computer-implemented method for providing agricultural spray information, the method comprising:

using a computer processor configured to;

analyze spray particulate data of sprayed agricultural fluids to identify a droplet size distribution of the sprayed fluids;

group droplets within the droplet size distribution into droplet size classes, each droplet size class representing a range of droplet sizes;

calculate a relative amount of the droplets within the droplet size classes;

receive a selection of an agricultural mixture corresponding to one of the sprayed fluids; and

transmitting for display the calculated relative amounts of the droplets within the droplet size classes for the spray particulate data based on the received selection,

wherein the representative droplets within a droplet size class are displayed with droplet size information.

9. The method of claim 8, wherein the representative droplets displayed are arranged within a distribution curve representing a distribution of size of the representative droplets based on the relative amounts.

10. The method of claim 8, wherein the droplet size information displayed comprises one or more of a range of droplet sizes represented, drift potential and leaf runoff potential.

11. The method of claim 8, wherein a value representing a span of the distribution is displayed using the computer display, wherein the span is (X₉₀−

X₁₀)/X₅₀.

12. The method of claim 8, wherein a value representing a volume mean diameter (VMD) of the distribution is displayed, wherein the VMD is a median droplet size of the sprayed fluid.

13. The method of claim 8, wherein the droplet size classes are predefined.

14. The method of claim 8, wherein the received selection comprises a set of selections of at least one of an active ingredient or an adjuvant in combination with at least one of a rate of spray, a spray pressure or a nozzle type.

15. The method of claim 14, wherein:
