Week 8 | w/c February 22nd 2021

Weekly Overview

Warmer at the start of the week but turning colder towards the end. Growth potential is expected to drop slightly and more rain is expecting in the north.

Average Maximum & Minimum Temperatures

Next 10 days

Last 10 days

Weather

The next 10 days can expect both average maximum and minimum temperatures to hold stable until the end of the week, where they then start to drop and some regions can also expect below freezing minimum temperatures for a couple nights. The average maximum temperatures are expected to be between 7-10 °C with average minimum temperatures expected to be between 2-4 °C.

Growth Potential

Next 10 days

Last 10 days

Weather

Another difference in growth potential for the UK compared to the last 10 days. All regions are now expected to be back in the low growth potential zone highlighted by the red circles.

Now is a good time to apply a granular fertiliser such as Ferro Top®6-0-12(+6MgO+8Fe). The perfect combination of nitrogen sources take full advantage of the cooler weather and Ferro Top® provides the perfect amount of K plus Fe, Mg and S which are all required to promote strong healthy turf, photosynthesis and discourage moss.

Base Nitrogen

Next 10 days

Last 10 days

Weather

Base nitrogen requirements (numbers inside the circles) are still required for all regions in the UK. Expect around 1 kg/N/ha for most regions.

It's always important to match the turf requirements for nitrogen as applying too little or too much can both have detrimental effects on turf health & performance and also increase disease occurrence, especially during this time of year.

Depending on your grass species and soil type, base nitrogen requirements may be more or less than the weather estimated figures.

Application Advice

Using PrecisionPro will help you calibrate your spreader and fertiliser correctly and also ensure correct walking speed is achieved. When applying any type of granular product it's important to keep a consistent spread width, therefore reducing missed or overlapped areas for a perfectly treated surface.

Rainfall

Next 10 days

Last 10 days

Weather

Regions above the red line can expect at least 20 mm of rainfall over the next 10 days, while regions below the red line can expect minimal amounts of rainfall. Dry towards the south with more rain expected in the north.

Turf Stress

Next 10 days

Last 10 days

Weather

The next 10 days continues to show medium turf stress for regions highlighted with gold circles. For extra leaf protection, TurfRx Si which also contains calcium will help turf become less susceptible to invasive fungal diseases and insects while also standing up the plant for a cleaner cut.

The use of other products to help protect the plant such as Green Lawnger TR and Dew Dispersants will help reduce leaf moisture, help prevent disease and improve surface playability. The pigment technology in Green Lawnger TR will also help increase the turf canopy temperature, protect the crown from frost damage and accelerate thawing of snow and ice.

Delivering the correct nutrients and micronutrients during specific turf conditions is key to keeping your turf healthy and resilient to disease pressures and stress.

Plant Growth Regulator

Kinder-Parry model

Next 10 days

Last 10 days

Weather

As the weather is expected to turn slightly colder towards the end of the week, PGR applications of both Attraxor® and Primo Maxx II® should not be applied. We will continue to monitor the conditions as it's important to time applications of Attraxor® inline with the "boot" stage of the poa annua plant.

Growing Degree Days

Next 10 days

Last 10 days

Weather

GDD is expected to decrease over the next 10 days for all regions.

Poa Seedhead Emergence

Next 10 days

Last 10 days

Weather

Minimal / No poa seed head emergence is still expected for all the UK.

Seed Germination Days

Agrovista amenity overseeding weather data helps you apply the right seed at the right time, maximising germination and ensuring optimum establishment. Using our amenity weather data, we can highlight the amount of base germination and optimum germination days that are occurring over the next 10 days.

Bent

Next 10 days

Last 10 days

Weather

Expect more No Germination days over the next 10 days for the UK.

Remember it's important to ensure correct seed to soil contact for each type of seed.

Fescue

Next 10 days

Last 10 Days

Weather

Now could still be a great time to take advantage of overseeding with fescue as some regions are still displaying a good amount of Base Germination days.

Always ensure correct seedbed preparation for optimum soil to seed contact.

Rye

Next 10 days

Last 10 days

Weather

Rye can expect mainly Base Germination days to occur over the next days with a few regions also displaying Optimum Germination days. Overseeding with Rye is recommended, taking full advantage of the current weather conditions.

Always ensure correct seedbed preparation for optimum soil to seed contact.
