Data Story
About Soil in San Juan County, Utah
Red rocks and alkaline desert soils
Local pH measurements are not yet recorded, but they typically exceed the national 6.5 median in this arid landscape. The soil reflects the deep geological history of the Colorado Plateau.
Sand and silt define the canyonlands
Specific composition percentages are missing, though the region is famous for its sandy textures. These materials provide great drainage but often struggle to hold onto vital nutrients.
Low organic matter requires active management
Without specific county numbers, the 2.0% national organic matter average is a more likely baseline than the state average. Focus on building up soil health to overcome the dry, high-desert conditions.
Flash floods highlight drainage importance
Official drainage groups are unmapped, requiring landowners to observe their own site's runoff patterns. Rapid drainage is common in sandy patches, making frequent, light watering necessary for crops.
Thriving in a sunny Zone 7a
Grapes and fruit trees flourish with the long growing season and abundant sunlight. Protect your young plants from the intense desert sun to ensure a successful harvest.
