Pre-Season Rolling

This is typically used to refer to the type and amount of rolling carried out during February to April for the preparation of a cricket square in anticipation of playing season preparation work.

  Pre-Start Checks

Before using any item of equipment it is important, as well as good practice and a legal requirement, to carry out preliminary checks to ensure the equipment is not just safe to use but also that it can be used effectively and efficiently. All checks will inspect for any leaks, damage or obvious incorrectly fitted feature.

  Pricking

Shallow penetration, typically up to a depth of about 40mm, of a turf surface to improve surface aeration and specially to aid the infiltration of water. It is also helpful in providing a shelter for newly sown grass seed, so as to aid germination and to improve the washing in of a fertiliser into the rootzone.

  Proactive Seeding

A contemporary modern name for the overseeding of a turfgrass surface, especially golf greens, during the spring and summer seasons to take advantage of good germination and establishment rates of desirable grasses and to reduce the competition and problems which arise from undesirable grasses such as Poa annua. In practice this is just the use of different words for the common practice of overseeding in spring and late summer, which greenkeepers already carry out and aim for suitable environmental conditions to get the most from their seed. Where the term might differ slightly from tradit

  Renovation

A range of activities, which mostly involve machinery, and which are undertaken to carry out a relatively major 'overhaul' of a turf surface and disturb the underlying rootzone. Renovation work will typically take place at either the end of a playing season for a sports surface; at the end of the summer to early autumn for an amenity turfgrass surface; or after an event, which has taken place, and which has caused significant damage or compaction to a turf surface.
