To help the course team compile the feeding and treatment program for the greens, we employ a specialist company who attend site to carry out a soil analysis survey every two years. Core samples are taken from the greens and sent to an agronomy laboratory for analysis, the data produced from these tests is used to check the underlying health of the greens and to decide on future treatment programs. You will notice in 2017 only 5 greens were sampled to gain an average overview, this has been increased to include more greens over a period of time to give more detailed data.
The results of the soil samples give values for pH Values, CEC, Magnesium, Iron, Sulphur, Phosphorous, Potassium and Calcium. We have collated the results for the past 3 sample sets and displayed them in a bar chart format below. With each data set is also a brief description of what each element is, and the effect it has on the greens.
Summary of the 2021 Test Report (Sherriff Amenity Services)
With reference to the soil samples collected for chemical analysis and the enclosed results, I am able to offer the following comments and recommendations.
The mean acidity value is pH6.14 compared with pH5.94 in 2018 and is now in the slightly high area of the summary table. In response, we recommend the use of strongly acidifying ammonium and iron sulphate based products, although as the latter is also slightly high, it will be necessary to encourage leaching by ongoing aeration and thatch control. This will also promote a decline in the slightly high sulphur content. Aim to retest towards the end of 2021.
