Fichas del conjunto (25)
- 1Class 1These soils have no significant limitations to use for crops
- 2Class 2These soils have moderate limitations that restrict the range of crops or require moderate conservation practices
- 3Class 3These soils have moderately severe limitations that restrict the range of crops or require special conservation practices
- 4Class 4Theses soils have severe limitations that restrict the range of crops that can be grown or require special conservation practices to overcome or both
- 5Class 5These soils have very severe limitations that restrict their capability to producing perennial forage crops and improvement practices are feasible
- 6Class 6These soils are capable only of producing perennial forage crops and improvement practices are not feasible
