Table 1. Soil and Sand Recommendations

Material Use Characteristics and Application Tips

Soil All When soil modification is not needed the existing soil or one similar in texture can be used. Pull cores, allow cores to dry on the surface and then drag to have soil fill in aeration holes.

Sand L,C,P

Sand: Use 100% sand should be angular or medium coarse.

Make sure the sand source will be available for future use.

Soil Mix: Use a mix with 80% sand and 20% organic matter. The mix should not contain more than <51% fine gravel (Concrete Sand) and <10% silt + clay or 2-5% very fine sand, 2-5% silt, 2- 5% clay.

After applying the topdressing material, first pull the drag mat making small circles then in large ovals so the material can filter into the aeration holes and also provide a level field.

Compost All Shall be mature, screened, have a fine particle size, be within the pH range of 6.5-8.0 and have a low salt content. Compost should be tested. Apply no more than ¼ inch per application.

Crumb Rubber

Shall have a small particle size: 0.05-2.0 mm. Apply at a ¼ inch depth per application until a cumulative depth of ¾ -1 inch depth is achieved over time. This material is expensive.

Uses:

L: to level minor depressions T: to reduce thatch C: to reduce hard compacted soils (following a cultivation practice) P: to improve aeration and drainage S: to improve seedbed for overseeding
