Standard Guide for Construction or Renovation of Native-soil Athletic Fields
SIGNIFICANCE AND USE
4.1 A dense, uniform, smooth and vigorously growing natural turfgrass sports field provides the ideal and preferred playing surface for most outdoor field sports. Such a surface is pleasing to the spectators and athletes. A thick, consistent and smooth grass cover also increases playing quality and safety by providing stable footing for the athletes, cushioning their impact from falls, slides or tackles and cools the playing surface during hot weather.
4.2 Sand is commonly used to construct high performance athletic field rootzone systems. Sand is chosen as the primary construction material for two basic properties; compaction resistance and improved drainage/aeration state. Although sand-based fields generally provide for a higher level of performance, the costs associated with constructing/developing a proper, high-performance sand-based field often precludes its use for many athletic field construction projects. In these instances soil-based fields constructed with either native or imported soils; either topsoil or subsoil material modified to mimic the properties of a natural topsoil (a manufactured topsoil). These soils are sometimes modified with amendments to improve their performance properties either at the time of original construction or during a subsequent renovation. Although not approaching the same performance properties of a proper sand-based field construction; the implementation of proper design, construction, and athletic field maintenance can produce soil-based athletic field rootzones with acceptable performance characteristics.
4.3 Properties of both the soil and grass plants must be considered in planning, constructing, and maintaining a high quality athletic field installation. Turfgrass utilized must be adapted to the local growing conditions and be capable of forming a thick, dense, turf cover at the desired mowing height. Soil-based fields provide varying levels of soil stability but such conditions often deteriorate rapidly under hi...
SCOPE
1.1 This guide covers techniques that are appropriate for the construction of athletic field rootzones using native-soil. This guide is also applicable to soils which are not native to the site but are natural (non-sand) imported soils. This guide provides guidance for the selection of soil materials, amendments, and methods for use in constructing these types of athletic field rootzones. Soils having a texture of Sandy Loam or coarser should be utilized for soil-based rootzone construction. Soils which are finer textured than listed above may be employed for rootzone construction but should be sand-modified to meet the performance criteria of this standard. If fields are constructed with soils which are finer textured, they will not be capable of meeting the performance criteria in this standard. Despite performance limitations, fields which are constructed with finer textured soils (due to logistics or budget constraints) may still be able to conform to the slope/grade criteria (see 5.1, 5.4, and Table 1). Sand modified rootzone constructions are not addressed by this standard.
1.2 Decisions in selecting construction and maintenance techniques are influenced by existing soil types, climatic factors, level of play, intensity and frequency of use, equipment available, budget and training, and the ability of management personnel.

Overview
ASTM F3339-20: Standard Guide for Construction or Renovation of Native-soil Athletic Fields offers comprehensive guidance for building and renovating athletic fields using native or natural (non-sand) soils. Developed by ASTM International, this guide addresses the selection, blending, and implementation of soil materials and amendments, with an emphasis on optimizing sports field performance and player safety. The guide is especially relevant for the construction and renovation of sports fields for activities such as soccer, football, baseball, and other field sports that benefit from vigorous natural turfgrass cover.
Key Topics
- Soil Selection and Amendment: Guidance on identifying and using suitable native or imported soils, preferably sandy loam or coarser, to form the rootzone. Soils with finer texture can be modified with sand to meet performance needs.
- Design Considerations: Emphasizes the importance of surface drainage, rootzone composition, and adapting turfgrass selection to local climate and field use intensity.
- Blending and Quality Control: Details procedures for rootzone blending, including testing and calibration to ensure homogeneity and conformance to physical and chemical property specifications.
- Surface Grading: Recommends laser-guided equipment for precise subgrade and finish grade installations, to promote even drainage and playability.
- Turf Installation: Covers best practices for seeding, sprigging, and sodding, including species selection and methods that protect field grade and turf integrity.
- Project Management and Teamwork: Highlights the need for collaboration among designers, agronomists, quality control agents, and contractors throughout the project lifecycle.
Applications
Practical uses of ASTM F3339-20 include:
- Sports Field Construction: For new projects where cost or site constraints make sand-based systems impractical, this standard offers solutions for effective soil-based field construction.
- Athletic Field Renovation: Guidance on soil modification and renovation processes to improve performance on existing fields using native or imported soils.
- Municipal, School, and Community Fields: Enables grounds managers and facilities personnel to implement construction and maintenance techniques suited to available resources and local conditions.
- Field Maintenance Planning: Assists in establishing appropriate maintenance regimes-including mowing, irrigation, fertilization, and aeration-to sustain turfgrass quality and field safety.
- Ensuring Player Safety and Field Performance: By promoting dense, uniform turfgrass cover and stable footing, the guide helps reduce athlete injuries and enhances playing conditions.
