Phosphorus, rootzone volume, and algae

This is about partitioning the growth flush after a rain. What's causing that growth flush? I made some calculations, using New Forest GC in the UK as an example. The increased soil water content from a 20 mm rain, in this example, would increase daily clipping volume from 10 mL/m2 to 22 mL/m2, ...

I've updated my recommendation for the sand quantity to apply for every unit of clipping volume harvested, if your goal is to keep surface organic material constant. Bjarni and I discussed topdressing by this method and the new equation that finds this sand amount. We discussed this post: https ...

I looked at sand particle sizes at the top of putting green rootzones, and compared those particle sizes to what is in the sand topdressing. The average results of this analysis are presented in this episode. The chart discussed is available at https://www.paceturf.org/gallery/detail/particle-s ...

I looked at the temperatures and dew points for a range of cities around the world during the first month of the most recent meteorological summer. June 2026 in the northern hemisphere, and December 2025 in the southern. The blog post discussed is: https://www.asianturfgrass.com/post/first-month ...
