About Soil in Lea County, New Mexico
Alkaline Sandy Plains
This soil leans alkaline with a pH of 7.51, closely matching the New Mexico state average of 7.48. It sits a full point above the national median pH of 6.5, influencing which nutrients are available to plants.
High Sand Composition
Sand dominates the profile at 67.8%, with clay making up only 13.6%. This sandy makeup ensures excellent drainage but limits the soil's ability to hold onto vital nutrients for long periods.
Low Organic Reserves
Organic matter levels of 1.05% trail the state average of 1.27%. Because the water capacity of 0.114 in/in is lower than the state average, frequent irrigation is necessary for plant survival.
Potential for Unexpected Puddling
The soil falls into Hydrologic Group D, indicating that while surface layers are sandy, deeper layers may restrict water infiltration. This can lead to unexpected puddling during intense southeastern storms.
Desert Gems in Zone 8a
Zone 8a gardeners should prioritize desert-adapted perennials, succulents, and lavender. Adding compost or manure is the best way to improve this soil's performance for vegetables.
