Systems and methods for placing and analyzing test plots
Systems and methods and apparatus for placing a plot in an agricultural field. Systems and methods are also provided for selecting a plot location based on primary and secondary parameters, for selecting a plot location based on user-defined parameters, and for allowing a user to accept or reject proposed plot placement.
1. A method for generating a plot in a field, the plot to be planted with a planter having row units, the method, comprising:
receiving a set of plot selection parameters specifying plot characteristics of a plot in a field and a crop to be planted in the plot;
based on a first crop yield of a first region, a second crop yield of a second region, and a third crop yield of a third region, dividing the field into at least the first region, the second region, and the third region, the first region assigned a first population rate of the crop planted in the first region, the second region assigned a second population rate of the crop planted in the second region, and the third region assigned a third population rate of the crop planted in the third region:
ranking the first population rate, the second population rate, and the third population rate according to the first crop yield, the second crop yield, and the third crop yield;
determining, for each of said first population rate, second population rate, and third population rate, average crop yields across the field and multiple different fields:
ranking said first population rate, second population rate, and third population rate according to the average crop yields across the field and the multiple different fields; and
generating, based on the set of plot selection parameters and a result of the rankings, a prescription map including the plot in the field, a first plot population rate of the crop to be planted at ones of multiple locations in the plot and a second plot population rate of the crop to be planted at different ones of the multiple locations in the plot, the first plot population rate being equal to the population rate ranked first based on the average yields, the second plot population rate being equal to the population rate ranked first based on the first, second, and third crop yields.
2. The method of claim 1 , further including:
controlling an application rate based on the prescription map.
3. The method of claim 2 , further including:
displaying a first location of the multiple locations of the plot during harvesting.
4. The method of claim 1 , further including based on a set of implement characteristics, determining plot dimensions of the plot.
5. The method of claim 4 , wherein the set of implement characteristics includes implement characteristics of equipment to be used in harvesting the field.
6. The method of claim 4 , wherein the set of implement characteristics includes a width or number of rows of a combine head to be used in harvesting the field.
7. The method of claim 1 , wherein the prescription map including the plot includes a geographic location of the plot.
8. The method of claim 7 , wherein the set of plot selection parameters includes a risk preference.
9. The method of claim 7 , wherein the set of plot selection parameters includes a fraction of acreage to be placed in plots.
10. A method of generating a seed population prescription map including multiple base rate zones, and multiple plots within each base rate zone, the method comprising:
identifying a field boundary of a field;
identifying multiple base rate zones within the field boundary;
assigning a base population rate to each base rate zone;
identifying valid plot placement regions within each base rate zone;
determining plot dimensions based on an implement characteristic of an agricultural implement used to harvest a crop from at least one plot in the field, the implement characteristic including a width or number of rows of a combine head of the agricultural implement to be used in harvesting the field planted according to a prescription map;
placing multiple plots in each of the multiple base rate zones based on at least a first placement rule, the first placement rule requiring, for each of the multiple plots, a minimum number of base rate cells adjacent to each of multiple sides of the multiple plots, the base rate cells having a minimum area; and
generating, based on the plot dimensions and the placement, a prescription map including the multiple plots placed in the field.
11. The method of claim 10 , further including: receiving second input that comprises a desired ratio between an area of the multiple plots and an area of a region enclosing the multiple plots.
12. The method of claim 10 , further including:
determining population rates within each of the multiple plots based on a third input.
13. The method of claim 12 , wherein the third input includes a desired variation in population rates.
14. The method of claim 10 , further including:
providing a graphical user interface to accept or reject plot locations; and
altering the placement of the multiple plots based on a rejection input received via the graphical user interface.
