Each of the grass plants in our green is akin to a little factory where Carbon Dioxide and Water are broken down and converted to a sugar based plant food that can be used immediately to fuel the plant's growth processes or converted to starch and stored throughout the plant for future use.
Performance turf requires heat and moisture and it is inevitable that you will have to turn to your irrigation system at this time to keep your green’s progress moving forward. Failure to keep up now could result in a disastrous season later on when the green dries out unevenly, succumbs to Localised Dry patch or simply doesn’t perform due to a lack of moisture early in the season.
We are familiar with the concept of our grass plants being composed mostly of water (75-85%), but what else is in a grass plant? The answer is that the dry matter of the plant is made up of a mix of 16 elements, commonly referred to as the essential nutrients. We describe them as essential because the plant can't exist or complete its life cycle if any of these nutrients are lacking to any great degree.
The plant uses a process called Respiration to drive growth and development. In much the same way that we respire, i.e. burning food to grow, develop and keep our bodies healthy, plants burn the food created by photosynthesis to fuel growth and to build and repair all of the component parts of the plant.
I once commented that there are only ever two real problems in bowling greenkeeping; compaction and thatch, with the rest of the myriad problems we come across being merely symptoms of these Big Two. Lately, I've revised that thinking, as the more I see of ill treated bowling greens the more I realise that, although they are important, even thatch and compaction are only symptoms too. The trouble we face in greenkeeping is that the industry wants us to treat symptoms. If we treated the root cause after all, we wouldn't need to buy half as much stuff! But before we get too carried away, let's have a recap on what bowls green compaction actually means.
