Andy Richards, Grounds Manager at Shrewsbury School, is a firm believer that aeration is one of the most important practices carried out by groundsmen, and this is exactly why he has recently purchased a new SISIS Javelin Aer-Aid.
Shrewsbury School is a co-educational independent schools for 13-18-year-olds.
“We have a good blend of academics and sports at Shrewsbury School,” says Andy. “Sport is a massive part of the School and there is a very strong house sport system.”
In discussing the maintenance procedures, Andy pin-pointed aeration as one of the most vital:
“On each pitch, we average 10-15 hours per week and we’ve got limited drainage. Therefore, one of the most important things we do is aeration and we aerate pitches all of the time. Grass lives and needs air like anyone else.”
Breathing life into Andy’s grass is his newly purchased SISIS Javelin Aer-Aid tractor mounted aerator: “It was the machine I wanted because I had previously trialled it and had good results. I Clegg hammered the pitches before and after using the Aer-Aid and had noticed a massive reduction in hardness. I know that the Aer-Aid had recently undergone extensive Sports Turf Research Institute (STRI) trials and it came out with excellent results, which always gives you confidence and makes it easier to explain to the bursars why you want to purchase it.”
Over a three-month period, extensive STRI trials led by Dr Christian Spring examined how and if the Javelin Aer-Aid had an effect on the hardness of the turf, the root depth, water infiltration and disease. Christian reported: “It became obvious that the Aer-Aid improved maximum root and depth within the soil profile and also had the benefit of increasing the depth of the average rooting mass.”
With 10mm diameter ‘tipped’ tines working at 75mm (3ins) spacing, air is introduced from the Aer-Aid at a rate of 88 litres (3cu.ft.) per minute. These air injection tines are specially designed to use the maximum air available from the compressor and produces clean, fresh air, while also ensuring that surface disturbance is kept to a minimum. The cam trigger mechanism ensures that the air is always expelled at the bottom of the tine penetration, enabling treatment to be targeted precisely and consistently.
“We do all the normal types of aeration, but to actually be able to inject air into the surface as opposed to just a mechanical operation of it is a massive bonus,” says Andy. “It’s a really good machine, easy to use and we can see significant improvements since using the Aer-Aid.”
