Reducing environmental impact through targeted cultivation practices

2026

Extractive cultivation (EC) refers to any cultural practice involving the removal of subsurface material from a playing surface. By its nature, EC requires intensive mechanical operations, resulting in high levels of hydrocarbon consumption. In addition, the import and incorporation of replacement soil amendments involve further mechanical activity, increasing fuel use. The process also disrupts the soil’s natural capacity to function as a carbon sink through repeated surface disturbance and redistribution.

Traditionally, EC has been used to address underperforming rootzones. However, with the widespread adoption of sand-based rootzones, the routine application of this practice is increasingly questionable. At Elm Park, a policy of “necessity over habit” has been adopted in relation to EC. Playing surfaces are assessed using objective performance metrics, and EC is only undertaken where minimum performance standards are not met. Measurable indicators such as hydraulic conductivity and surface firmness are used to inform these decisions.

This approach allows Elm Park to avoid the routine annual application of EC common at many facilities, limiting its use strictly to identified need. As a result, the club has not carried out blanket EC practices for the past five years, with only objectively identified localised areas receiving targeted intervention.
