About Soil in Kings County, California

Alkaline Soils of Kings

Kings County has an average soil pH of 7.50, which is significantly more alkaline than the national 6.5 median. This high pH can limit the availability of certain nutrients for your plants. The county's overall soil score is 17.7, suggesting some natural limitations.

A Gritty, Sandy Mix

The soil is composed of 45.4% sand, 30.5% silt, and 22.8% clay. This high sand content means the soil is easy to work and drains relatively quickly. However, it may struggle to hold onto nutrients compared to heavier clay soils.

Low Natural Organic Matter

Organic matter is quite low at 1.22%, trailing the 3.30% state average and 2.0% national average. The available water capacity is 0.121 in/in, which is also below the California average of 0.141. Regular additions of compost will be necessary to boost soil health and water retention.

Managing Agricultural Runoff

Specific drainage and hydrologic groups are not listed, but the low soil score indicates management challenges. With high sand and low organic matter, water may move through the surface quickly but potentially pool elsewhere. Careful monitoring of your irrigation cycles is essential for success.

Cotton and Tomato Kingdom

Hardiness Zone 9a is a powerhouse for sun-loving crops like cotton and tomatoes. To succeed, focus on building up your organic matter to help the soil hold onto moisture. Your garden will reward you with heavy harvests if you feed the soil well.
