Abstract

A process of recommending crop varieties based on management categories. The management categories are determined by utilizing indices, which measure the economic implication of physical and chemical properties of a specific soil type in a region. The management categories may then be indicated graphically by indicia overlaying digitized soil maps, each of the indicia grouping soil types within a management category. Each crop variety is characterized by how the crop variety performs in each of the management categories. Each of the crop varieties may then be assigned an indicium of the management category for which it is adapted.

Claims

1. A process of selecting a crop variety, comprising:

viewing a digitized map of a field, the digitized map depicting areas denoted by an indicium, said areas having an optimized adaptation for a variety subset; and

selecting the crop variety from the variety subset, the variety subset denoted by the indicium.

2. The process of claim 1, in which the indicium includes a color.

3. The process of claim 1, in which the crop variety is a corn variety or a soybean variety.

4. The process of claim 1, in which said indicium is a classification at least partially based on physical properties of soils present in the field.

5. The process of claim 4, in which the physical characteristic includes slope, erosion, soil water holding capacity, soil texture, pH, permeability, seasonal presence of saturated soil layers, organic matter, or cation exchange capacity.

6. The process of claim 5, in which the crop variety is a soybean variety and in which the indicium indicates Phytophthora or iron chlorosis predisposition in the digitized map and Phytophthora or iron chlorosis tolerance in the soybean variety.

7. The process of claim 5, in which the crop variety is a corn variety and in which the indicium indicates drought predisposition in the digitized map and drought tolerance in the corn variety.

8. A process of integrating a set of soil characteristics and a set of crop variety characteristics, comprising:

obtaining a set of physical properties characterizing a subset of soil types;

using the set of physical properties to obtain a set of corresponding indices;

using the set of indices to obtain a set of management categories, each of the soil types characterized by one of the management categories;

obtaining a set of adaptation characteristics for a corresponding set of crop varieties; and

using the set of adaptation characteristics of each of the set of crop varieties to designate which of the set of crop varieties should be planted in each of the management categories.

9. The process of claim 8, further comprising assigning an indicium to each of the set of management categories.

10. The process of claim 9, in which the indicium includes a color.

11. The process of claim 8, in which the crop varieties are corn varieties or soybean varieties.

12. The process of claim 8, in which the physical properties include slope, erosion, soil water holding capacity, soil texture, pH, permeability, seasonal presence of saturated soil layers, organic matter, or cation exchange capacity.

13. The process of claim 8, in which the crop variety is a soybean variety and in which the indicium indicates Phytophthora or iron chlorosis predisposition in the digitized map and Phytophthora or iron chlorosis tolerance in the soybean variety.

14. The process of claim 8, in which the crop variety is a corn variety and in which the indicium indicates drought predisposition in the digitized map and drought tolerance in the corn variety.

15. A process of determining crop management categories, comprising:

compiling a set of physical properties for a set of soil types in a region; and

assigning each of the soil types in the region to one of the crop management categories.

16. The process of claim 15, in which the physical properties include slope, erosion, soil water holding capacity, soil texture, pH, permeability, seasonal presence of saturated soil layers, organic matter, or cation exchange capacity.

17. The process of claim 15, in which the crop management categories are indices grouping one or more of the set of soil types according to how crop plants grow and develop thereon.

18. The process of claim 17, in which the crop plants are corn plants or soybean plants.

19. The process of claim 15, further comprising a unique indicium to each of the crop management categories.

20. The process of claim 19, in which the indicium includes a color.

21. A process of determining seeding rate of a variety being seeded, comprising:

providing a planter with a variable seeding rate, the planter in electrical or electromagnetic communication with a digitized soil map, the digitized soil map having areas defined by crop management categories; and

seeding the variety, the seeding rate of the variety determined by the position on the planter relative to the crop management categories.

22. An integrated data set, comprising:

categories describing corresponding sectors of a field and derived from soil indices, each of said categories describing one of said corresponding sectors of the field having a unique indicium; and

categories describing corresponding sets of crop varieties and depicting the response of the crop variety set to the soil and environmental indices, each of the categories describing a crop corresponding to the categories describing the sector of the field and having the unique indicium.

23. The data set of claim 22, in which one of the categories describing the sector of the field are further determined by an impervious soil layer present in the sector of the field.

24. The data set of claim 22, in which the crop variety is a corn variety.

25. The data set of claim 24, in which the categories describing a sector of the field describe the propensity of the sector to experience a water shortage during a growing season.

26. The data set of claim 24, in which the categories describing a sector of the field describe the propensity of the sector to experience water excess during a growing season.

27. The data set of claim 22, in which the crop variety is a soybean variety.

28. The data set of claim 27, in which the categories describing a sector of the field describe the propensity of the sector to promote growth and development of Phytophthora during the growing season.

29. The data set of claim 27, in which the categories describing a sector of the field describe the propensity of the sector to induce iron chlorosis during the growing season.

30. The data set of claim 22, in which the indicium can be graphically depicted as a color.
