General Committee Meeting Minutes from February 2019.
If you have any questions please don’t hesitate to contact me :
On the course.
Darren Burton – Head Greenkeeper
Phil Rutt – Deputy Head Greenkeeper
Andrew Pledger – ICL Technical Area Sales Manager.
Bore Hole Water – Sent for anaylsis
Core Samples Taken
3rd, 7th, 15th USGA Greens.
1st, 10th, 11th Clay Greens.
With the help of John Noyce (Collier Turf Care) and his knowledge of the problems that Chestfield has historically faced in the past. the decision was made to look into ways of improving our water quality from the existing bore hole.
After meeting with Andrew Pledger (ICL) at this year’s BTME in January. AP kindly visited the course today to take samples of our Water and Soil Analysis of six greens. This would normally bring a charge of £140.00 but because we use the ICL products on a regular basis there is no charge for this visit.
The aim of the Water Analysis is:
To see exactly what is in our water?
Is there any form of contamination?
And what effect is it having to the greens, Approaches and Tees?
A Sample was taken from the Irrigation Tanks that have recently been filled with fresh Bore Hole water.
These results will take upto 10 days to receive back and a report will be issued in due course.
Cores taken from our USGA Greens on the 3rd, 7th and 15th .
Cores taken from our Clay Push up greens on the 1st 10th and 11th.
Five to six cores were taken from each green, bagged and labelled.
These samples will be analysed and a report will be issued at the same time as the water analysis.
However whilst taking core samples we can learn a lot from what we see but also what we can smell.
Indicated in red in the picture are the areas of Anaerobic soil.
What is Anaerobic soil?
The term black layer is more commonly used among sportsturf managers. This problem is an anaerobic condition that can develop in rootzones due to a number of environmental and cultural factors. This condition is more common on sand based rootzones, although it can also occur on other rootzone types.
Black layer appears as a black, foul-smelling continuous or discontinuous subsurface layer in turfgrass rootzones. Chemically, black layer is a deposit of metal sulphides, which form when hydrogen sulphide gas reacts with metal elements in the soil. For hydrogen sulphide to be released, the rootzone conditions must favour the growth of sulphur reducing bacteria, which requires water and soil organic matter. The organic matter (THATCH) provides the food for the microbes, and water keeps the microbes hydrated. Soils must be relatively anaerobic (low in air) since these sulphur reducing bacteria do not survive very well in well aerated soils. The anaerobic conditions can be caused by numerous factors such as compaction, (When the ground is thawing after a Frost) excessive irrigation, (Irrigation proficiencies) organic matter accumulation, (thatch build up), sulphur application or movement of colloidal particles (Water Quality). Coupled with this, sulphur must be available within the soil.
Effects of Black Layer
Once black layer
development occurs drainage dramatically decreases in the soil. As the layer
increases, the pores in the soil become filled with the hydrogen sulphide gas.
Research has found that hydrogen sulphide gas is lethal to turfgrass by
stopping root respiration and killing the turfgrass plant.
Soils with low levels of oxygen are usually darker in colour than well oxygenated rootzones. If black layer is present, particularly on a sandy soil, a dark coloured ring will form in the rootzone below the soil surface, which can range from less than an inch to several inches in thickness. Areas of turf may turn a bronze colour and thinning of the grass is likely.
The most important measure with black layer is prevention by ensuring that the soil is well aerated and drains freely. This can be achieved through numerous techniques including
Sample Taken from the 10th Green at 12.40pm
Sample from the 10th Green at 4pm
Its not what’s going on, on top of the ground. Its what’s
happening beneath it.
LOOK – TOUCH – BREAK – SMELL – LEARN – UNDERSTAND
Captain Darren Bovis and Clubs assistant professional Simon Page today visited the Pilgrims Hospice in Canterbury. After spending time with some of the patients in the day hospice they were photographed proudly holding the cheque for money raised so far by our members. Another moment to be proud of our club.
Leila Ilkhan, Community Fundraising Manager for the Pilgrims commented “As I am sure you have come to realise, the day hospice is a great service for our patients and their families to enjoy a social environment whilst taking part in activities that enhance their wellbeing, physically and emotionally. We are thrilled that you chose to support the hospice as your chosen charity and can’t express how much the money that you and the club have raised will make a difference, enabling us to continue providing a range of services and support for our patients and their families. We are looking forward to welcoming John and Sally to the team in April and are delighted to be able to carry on working with such a great club.”
