Top Maker to Remove 50% of the Surface:

• You're using a top maker (a type of machine) with every second blade to reduce the existing Kikuyu grass surface by 50%. This method is likely used to aerate the ground and remove some of the old turf to prepare for new growth. Kikuyu grass is a vigorous type of grass, and removing some of it can help with soil aeration and allow better establishment of other grass types.

Backfill with Sand:

• After removing part of the Kikuyu surface, you're backfilling the area with sand. Sand can improve drainage, reduce compaction, and help in leveling the surface. This also allows the newly introduced grass species (like ryegrass) to establish itself more effectively.

Ryegrass Establishment:

• Ryegrass is being introduced to the site, possibly to improve the turf's quality or to provide a more suitable surface for the given environment. Ryegrass is often chosen for its rapid germination and growth, making it ideal for overseeding or establishing a new lawn in cooler seasons.

Setting up the POD System for Irrigation:

• You're installing a POD (Point of Delivery) irrigation system, which could refer to a specific type of sprinkler or drip system designed to efficiently water the turf. This ensures that the ryegrass gets the right amount of water for establishment, as consistent moisture is crucial for germination and early growth.

Growth Phase:

• After these steps, you're allowing the ryegrass to grow. During this phase, you’ll likely need to monitor water levels, nutrients, and mowing practices to ensure the new turf develops healthily.
