Granulated Sulphur GTS 2250

Precision Sulphur supply via decoupling

Convenience is not always agronomically correct.

GTS 2250 delivers cost affective Sulphur to a crop, decoupled from traditional commodity products. Allowing for the correct purchase and application of Nitrogen and Potash in the spring. Plants tissue can accumulate sulphate when it is available in excess of needs, but plants cannot translocate extra sulphate to younger tissue if soil sulphate supplies run out.

GTS 2250 looks at the seasonal sulphur issues and delivers a constant supply of sulphur over the crops foundation and construction phase, linked in with soil microbial activity, this becomes available when the crop demands it, GTS 2250ensures the crop is adequately supplied with enough sulphur at the start of its lifecycle to underpin its requirements over the season.

In many areas of the UK shortage of sulphur has now become the single largest limiting factor restricting plant productivity. It is well documented about reduction of atmospheric deposition of sulphur (60% of UK receives less than 12 kgs/ha/yr) and the increased demand from crops yields as yield potential increases through better efficiency from Nitrogen, (NUE). Sulphur plays a very key role in this and all metabolic pathways within a plant.

Trials consistently detail agronomical and financial benefit from applying sulphur to soils that are prone to deficiencies.

The question is no longer whether sulphur should form part of a program, but rather how it is best incorporated within a farm nutrient plan. What is the best way to supply S to the crop?

Key Decision Criteria

• Consistent supply of the Sulphur throughout the growth of the crop
• How it could affect soil nutrient and the pH properties of soils
• Balanced N:S ratios
• Ability to decouple in season Nitrogen sulphur applications.

• Constituent of enzymes and vitamins
• Role in Initiating protein synthesis
• Essential for Nitrogen fixation in legumes
• Essential for the satisfactory uptake of Nitrogen
• Necessary for chlorophyll formation
• A constituent of several volatile organic compounds which give characteristic odours to mustard, garlic and onion.

Sustainable Soil Management (SSM) is an Independent service focused on delivering the sound principles of soil health and balance known as Bioscence®, www.soiladvice.com Bioscence® is a farming system based on sound ecological and agronomic advice, which manages soil fertility to optimise its full potential. Bioscence® is a sustainable system practised on farms throughout the UK and Ireland for many years and more recently has been introduced further into Europe.

Application Rates

Winter OSR 35 - 50kg/ha
Winter Cereals 15 - 25kg/ha
Brassica 45 - 50kg/ha
Grassland 35 - 50kg/ha
Peas 15 - 25kg/ha

Application rates
Oilseed rape requires 80-100 kg/ha S03,)
(32 - 40 kg/ha of GTS 2250.)
Cereals would require around 50 kg/ha So3
(20 kg/ha of GTS 2250)
Sulphate-sulphur, like nitrate-nitrogen, is very mobile in soil. After heavy precipitation or irrigation events, sulphate leaching from the topsoil into subsoil away from roots can induce S deficiencies. Sandy soils have the greatest potential for sulphate leaching. This problem can be overcome by using elemental sulphur that does not leach. It will slowly oxidise to sulphate during the early part of the growing season thereby supplying the plants with adequate Sulphate sulphur. (So long as you have applied the required amount)

It has been proven in trials that additional sulphur in the autumn as S has improved yields and crop qualities, compared to just increasing the sulphate levels in the spring.

It is advised that 20-40kg /Ha of GTS 2250 is to be used in the autumn as part of a program to supply sulphur in the autumn as a foundation to the full sulphur strategy on the farm. Thiscan be followed up with the required crop balance via spring applied sulphate sources e.g. fertilisers etc.

Diagnosis
Sulphur deficiency in the field can often be confused with Nitrogen deficiency.

Crop stunting and paling of leaves. But Sulphur will tend to show in the younger leaves whereas Nitrogen tends to express itself in older leaves first.

Oilseed rape the middle and upper leaves can show inter-veinal yellowing with flower petals being pale.
