Another huge benefit of aeration when you actually remove the aeration cores from the ground is the removal of the associated thatch with the core. Thatch is excessive organic matter consisting of roots and stems that form the soft mat directly below the green leaves of the turf stand. Excessive thatch is the main culprit of the soft conditions we experience at Granite Bay in the summer because it acts like a sponge retaining a portion of applied irrigation. We need to continue to reduce this excessive organic matter to improve conditions. We have some different plans to accomplish that goal this year, in part, which I will now explain.
As planned we will start aerifyng the entire golf course beginning next Tuesday 4/6/10. We will start with the green’s which really need an aeration to get the bentgrass going & growing so as to catch up with the patches of Poa Annua. These two different growth rates definitely contribute to sporadic bumpiness we have been experiencing in the afternoons. We have not been able to roll the greens as much this spring to date because of the hit and miss rain storms which would have helped with this bumpiness. Rolling the greens when they are wet just compacts them further ultimately hindering rather then helping the situation. We hope to aerify and topdress a portion of the tees immediately following the greens and finish up what we missed the following week.
