Spiking 7th, 15th and 17th greens

We have spiked greens 15 and 17 this morning. We noticed a build up in black layer on those greens which is caused by anaerobic (lack of oxygen in the soil atmosphere) conditions. Basically not much airflow due to the amount of trees. The 7th also has a little which will be spiked tomorrow. Also it isn’t helped by the amount of water being applied during dryer periods.
