Soil Series and Fertilizer Application Challenges on Lackland AFB Grounds

Lackland AFB’s predominant soils, as identified by the USDA Web Soil Survey, include Houston Black clay and Lewisville silty clay loam, both characterized by high clay content, slow drainage, and a tendency toward compaction. These soils typically exhibit a pH range of 7.5-8.2, requiring careful selection of fertilizer formulations to avoid nutrient lockout. For optimal nutrient uptake, soil testing is recommended every 2-3 years, with amendments such as sulfur for pH reduction or compost at 2-3 inches tilled to a 6-inch depth. Fertilizer should be applied at a rate of 2-3 lbs nitrogen per 1,000 sq ft annually, split between spring and fall. Coordination with the base’s engineering and environmental offices is required for any large-scale soil amendment projects.

Seasonal Fertilizer Timing and Weather Considerations for Lackland AFB Lawns

Lackland AFB is located in USDA Hardiness Zone 8b, with average last frost dates in early March and first frost in late November. The optimal windows for fertilizer application are early May (soil temperature 55°F) and mid-September, avoiding the June-August heat stress period. The National Weather Service San Antonio Office provides real-time soil temperature and rainfall forecasts, which are critical for scheduling applications to prevent runoff. Key timing guidelines include:

• Spring fertilization: April 15 – May 15
• Fall fertilization: September 10 – October 15
• Avoid application before heavy rain (0.5 inch forecast within 24 hours)
• Do not fertilize during drought or when turf is dormant

Environmental Compliance and Stormwater Protection on Lackland AFB

All fertilizer use on Lackland AFB must comply with the Texas Water Code and the installation’s MS4 stormwater permit, which prohibits fertilizer or grass clippings from entering storm drains or water bodies. Maintain a 25-foot no-application buffer from wetlands and drainage ditches, and never apply fertilizer within 50 feet of Leon Creek or Medina River. The Texas Commission on Environmental Quality and EPA Region 6 oversee enforcement. Best practices include:

• Use drop spreaders to minimize drift
• Sweep granules from hard surfaces back onto turf
• Schedule applications when wind is below 10 mph
• Maintain records of fertilizer type, rate, and date for inspection

Municipal Coordination and Fertilizer Storage Regulations on Lackland AFB

Proper storage and handling of fertilizers are regulated by base policy and must align with Texas Commission on Environmental Quality guidelines. Fertilizer must be stored in original, sealed containers within secure, covered facilities, away from stormwater inlets and at least 50 feet from any water body. The Department of Public Works oversees compliance, including periodic inspections and reporting of inventory. Disposal of unused or expired fertilizer is coordinated through the base’s hazardous waste program, with collection scheduled quarterly. Key requirements:

• Store fertilizer off the ground on pallets
• Maintain secondary containment for liquid products
• Submit inventory reports annually by January 31
• Participate in hazardous waste collection events
