One of the key decisions that have to be made before a new sporting field is constructed is what substrate (native soil or sand) should be used beneath the turf on that field. This article discusses the key pros and cons of a native soil field and a sand-based field. Use this information to select the best field substrate for the school that you manage.

Native Soil Sporting Fields

Native soil sporting fields refer to fields where the naturally occurring soil in that area is used as a substrate for the turf on that field. Native soil fields are usually less costly to construct because the contractor doesn't have to ferry any soil to the site. These fields may also require limited watering because they usually have a high ability to retain water. The native soils also reduce the need to provide supplementary nutrients to the turf because the soil holds any nutrients present in the soil for long.

However, the frequent use of the sporting field can cause the soil to become compacted due to the heavy traffic that it endures during each sporting event. This compaction can increase the likelihood that athletes will sustain injuries as they use that native soil field. Furthermore, it can become challenging to drain the field quickly once it rains heavily. This is because the native soil won't let the water percolate quickly enough to leave the field free from water puddles. Consequently, sports events may be delayed or postponed once waterlogging makes the field unusable.

Sand-Based Sporting Fields

Sand-based fields refer to sporting fields where the native soil is excavated and replaced with sand that has been ferried in from another source. These fields are excellent for venues that will be used frequently. This is because the sand resists compaction. Secondly, sand-based sporting fields are ideal for locations that receive heavy rainfall. This is because water can quickly drain from the field without damaging the turf or soil structure.

However, sand-based sporting fields are very expensive in several ways. First, complex tests must be carried out in order to determine the best sand composition to use at the site. Secondly, regular tests must be done to establish how the composition of sand has changed over time so that remedial action can be taken. It is also expensive to ferry large amounts of sand to the construction site. Additionally, it is expensive to keep adding the nutrients that keep leeching through the porous sand.

Think carefully about the issues above before you select a substrate for the new sporting field that you would like to be constructed at your school. You should also talk to sporting field construction experts. Their suggestions about the best substrate for fields in your location will help you to make an informed decision.
