Briefly discuss the major threats to california's
soil resources.

The threats of California soil resources are soils, urban development

Explanation:

Native soils, unmodified by  human activity, are becoming  rare and we are losing the valuable  power they provide.  Soils in the Delta continue to subside.

Urban development has expanded into vast acres of prime farmland in California,  diminishing our capacity to produce sustainable food and fiber.Increased fire frequency will increase soil erosion, resulting in depletion of nutrients from the soil and polluting the surface waters that receive the runoff.

There are many threats to the soil resources in California some of them are Hydraulic mining, Forest fires, and Solar plant installation.
