Key Tasks for June
Consistently warm soil temperatures in June create ideal conditions for fertilisers with an organic component, whether that be straight organic fertilisers or organo-mineral. Organic sources of nutrition help to support the soil food web and manage the soil-plant system in a holistic fashion. Spring inputs of nitrogen aiming to get things going can be reduced and grass growth will naturally start to drop back as temperatures rise. In the wild, the plant would have now gone through its leafy growth spurt and be diverting energy into setting flower.
Calcium is a key driver of growth for roots and shoots, as it is responsible for the construction of cell walls. Calcium can become limited in dry soil, so ensuring soil levels are adequate and supplementing with foliar calcium helps it to maintain good health. Calcium, along with potassium, are essential for regulating stomatal function, helping the plant to better react to the onset of heat and water stress. Cold pressed liquid seaweeds contain plant hormones which also help to regulate against water stress and are a significant resource to be employed. Seaweed also contains hormones which promote germination and establishment.
Any areas which have been seeded in May will benefit greatly from the addition of seaweed. Carbon sugar sources and liquid humates will also drive establishment, promote soil biology and maximise the uptake efficiency of nutrition.
The use of wetting agents as part of a managed plan will pay dividends during June if hot weather occurs. Ideally, these should have started with the application of a block co-polymer in March at the latest, to give the soil a chance for the chemistry to accumulate in the soil.
Penetrant wetting agents will help applied irrigation and rainfall to enter the profile from the surface down.
Regular sarrel tine aeration is a key cultural means of maintaining soil moisture levels as the shallow but tightly spaced tines puncture a large percentage of the surface area, allowing gas to escape from the soil and better aiding the percolation of water from the surface.
Growth regulators applied during periods of good growth in anticipation of hot dry weather to come will help the plant to conserve energy and manage water stress, again mitigating drought pressure.
With respect to irrigation, a thorough soaking just before dusk gives the soil the maximum time to expel heat over night. Applying water at the end of a hot day creates a nice thermal blanket, trapping heat in the soil.
Little and often watering is appropriate for germinating seed and very young plants, but it is advantageous to thoroughly wet the profile and then let the soil dry down to just above wilting point if you can. This encourages the roots to penetrate and allows carbon dioxide to leave the soil and life-giving oxygen to enter.
Little and often watering also maintains surface humidity and will encourage algae, mould and fungi such a botrytis and Rhizoctonia spp. to attack swards.
Keep machines overhauled and clean.
Inspect and repair any watering or irrigation systems.
Continue to check and service your floodlighting systems.
Replace any worn tines on your aeration equipment.
Grounds Training was established in 2006 to provide a complete and unique service delivery training courses for the sports turf industry. We are now the go-to provider for on-site, bespoke training for groups. Alongside our renowned turf maintenance which now includes Lantra accredited Online courses. Grounds Training also works with the industry’s awarding bodies – Lantra and City & Guilds (NPTC).
Open courses for individuals to join are also offered at our Allscott (Telford) Training Centre, Most courses lead to Lantra Awards or NPTC qualifications; a small number of niche courses where the instructor is an experienced groundsman who is also Lantra Awards or NPTC registered, offer Pitchcare certification.
Whether your staff are involved with preparing and maintaining sports turf, operating ground care machinery and equipment or require a safe use of pesticides qualification, we have the course to suit them.
