If you’re growing arable or forage crops, giving them the right amount of Sulphur is essential for optimum yield, quality and profit margins. With atmospheric Sulphur levels falling dramatically, annual Sulphur applications are becoming the norm for today’s farmers.
But with a range of choices on the market, which one gives you the best return on your investment? Urea + sulphur-based products are a popular, affordable choice, but how well do they hold up against true granular products like CF DoubleTop®?
THE ADVANTAGES OF A CF APPROACH
CF DoubleTop combines Ammonium Nitrate with Ammonium Sulphate. Sulphur-rich and highly effective, it’s the most popular fertiliser of its kind. As a lower Sulphur option for little-and-often applications, we also make SingleTop®, combining Ammonium Nitrate with Calcium Sulphate.
Both products are formulated to a high specification in our UK factory. They’re specifically designed to provide immediately available Sulphur and minimise Nitrogen loss. Thanks to our precise manufacturing technique, they deliver Nitrogen & Sulphur in every granule, for reliable, accurate and consistent spread of nutrients across your crop.
Application of CF DoubleTop and SingleTop deliver a powerful combination of nutrients that support your crop quality, reliability, yield and profitability.
WHAT OTHER OPTIONS ARE AVAILABLE?
There are a range of products on the market that simply blend Sulphur or AS with urea. While they’re often cheaper to buy, they don’t spread well and are likely to separate, so they make poor economic sense, long term.
They’re a less direct way of delivering Sulphur and Nitrogen, both because they use urea rather than Ammonium Nitrate, and also because their granules don’t distribute evenly across fields. Urea and ammonium sulphate look very similar, so it’s hard to spot an uneven spread – which can lead to crop striping and lower yields. It all adds up to a less reliable, lower quality crop.
PRODUCT CHOICE MAKES A PROVEN IMPACT ON YIELD
A 2017 study from independent agricultural researcher Armstrong Ltd showed the major impact Sulphur fertiliser choices can make. The trial compared these systems:
• A urea-sulphur blend + straight urea
• Granulated urea-sulphur + urea
• CF DoubleTop + CF Nitram®
The results were clear. DoubleTop + Nitram produced 0.42t/ha more wheat than the granulated Urea Sulphur approach, and 0.9t/ha more wheat than the urea-sulphur blend. In financial terms, the study concluded that DoubleTop + Nitram could potentially boost margins by up to £114 per hectare, or £11,400 over 100 hectares.
"The results were unequivocal with the DoubleTop and Nitram combination out-yielding the urea-based options in all cases"
