Petroglyph Sodic Soil Reclamation

Land IQ worked with Petroglyph Energy, Inc. to reclaim sodic soil on a dairy farm site near La Veta, CO. Petroglyph discharged water from coal bed methane dewatering operations in the Cucharas River under permit from the State of Colorado. The discharge water was high in sodium, and resulted in high loading rates of sodium applied to corn fields irrigated with Cucharas River water. Land IQ, in collaboration with Petroglyph, farm ownership, the Colorado Oil and Gas Conservation Commission, and soil experts from the National Resources Conservation Service, designed and implemented a site evaluation, an intensive reclamation plan, and a monitoring plan to restore productivity on sodic farm soils. Land IQ’s expertise in salinity-related soil and crop management resulted in improvement in soil conditions and corn yields within one year.

City of Los Angeles Biosolids Beneficial Reuse Nutrient Management

The City of Los Angeles Bureau of Sanitation needed to complete a nutrient management and monitoring plan for their 4,688-acre biosolids and reclaimed water beneficial reuse site, Green Acres, in Kern County, CA. Land IQ staff developed a plan that included soil and plant tissue monitoring, assessing nutrient and soil chemical properties, determining local markets for farm crops, evaluating plant-available nitrogen status and loading rates, developing a biosolids loading rate tool that stores and manages farm data, interpreting groundwater monitoring data, and associated reporting and public relations efforts. The farm grows wheat, corn, alfalfa, sorghum and sudan grass. The information and tools in this plan assisted the City of Los Angeles in improving the quality of biosolids management and encouraging public communication about biosolids use through efforts with the National Biosolids Partnership.
