Polysulphate

In 2012, ICL introduced a new multi-nutrient fertilizer, Polysulphate, which is available to plants in its natural state. Available in its natural form, polyhalite (marketed as Polysulphate™ fertilizer) is UK-sourced and has a low carbon footprint. It delivers dependable high value, for low environmental impact. It is a natural, sustainable, dependable, organic fertilizer. \

Polysulphate™ fertilizer comes from the polyhalite layer of rock, over 1000m below the North Sea off the North Yorkshire coast in the UK. Deposited 260 million years ago, it lies 150-170m below the potash seam at the ICL UK Boulby Mine. It contains four nutrients which makes it a unique product: sulphur, potassium, magnesium,and calcium. Its nutrients are readily available for plant uptake.

Introducing Polysulphate™

Field experiments conducted worldwide using Polysulphate™ have demonstrated its efficacy in increasing crop yields and crop quality. The results have also indicated greater efficiency than standard sources of potassium and magnesium sulphates, as well as gypsum, with significant increases in yields.

ICL FertilizerpluS

ICL is expanding its Polysulphate family of products, to include PotashpluS (with four nutrients – K, Mg, S and Ca) and PKpluS (with five nutrients – P, K, Mg, S and Ca). These products give farmers a different choice of applying sulphur rather than nitrogen-based products, which run the risk of creating ammonia emissions, polluting groundwater and acidifying soils. The prolonged availability of the sulphate in Polysulphate products benefits the crop and is more aligned to its needs during growth. This makes them very efficient fertilizers and reduces loss through leaching.

Farmer’s Testimonial

2.4

By 2030, ensure sustainable food production systems and implement resilient agricultural practices that increase productivity and production, that help maintain ecosystems, that strengthen capacity for adaption to climate change, extreme weather, drought, flooding and other disasters and that progressively improve land and soil quality

13.3

Improve education, awareness-raising and human and institutional capacity on climate change mitigation, adaptation, impact reduction and early warning.

15.3

By 2030, combat desertification, restore degraded land and soil, including land affected by desertification, drought and floods, and strive to achieve a land degradation-neutral world.

Carbon Footprint of Polysulphate

Polysulphate is natural

Perhaps the most innovative aspect of PolysulphateⓇ is its low environmental impact. Polysulphate requires no processing and creates no waste products. The mineral is mined, crushed, screened and bagged with no chemical intervention or process. It therefore has a low carbon footprint fertilizer and helps farmers reach industry carbon targets.

In 2018, ICL conducted a full Carbon Footprint analysis for Polysulphate and has compared the findings to other common fertilizers. The analysis was conducted by Filkin & Co. EHS Limited, a U.K. consultancy specializing in LCA and Carbon Footprint research. The results are clear. The calculated global warming potential value for Polysulphate is 0.06 kg CO2e per kg of product. This value was found to be the lowest out of a group of leading comparable products (see chart above).
