Sulphur has been recognised as an essential element for plants for more than two centuries, but only in the last decades has sulphur deficiency emerged in agricultural crops.

Sulphur is regarded as a secondary nutrient even though plant requirements for sulphur are equal to and sometimes exceed those for phosphorus. However, sulphur is recognised as one of the major nutrients essential for plant growth, root nodule formation of legumes and plants protection mechanisms.

In organic production sulphur is the most important fungicide used. Moreover, it is the only fungicide in organic apple production for the main disease apple scab under colder conditions. Sulphur is also a major fungicide in conventional culture of grapes, strawberries, many vegetables and several other crops. It has a good efficacy against a wide range of powdery mildew diseases. Sulphur is one of the oldest pesticides used in agriculture.

The sulphur content of soils in many countries in Europe has been dropping for the last 30 years. In the past, 33 to 50 % of the sulphur in soils came from acid rainfall, but with less air pollution there is now less sulphur in rainfall. In the 1950s fertilizers routinely contained sulphur but this changed in the 1960s. As a result, the amount of sulphur reaching the soil has diminished. Unless sulphur fertilizers are used, the sulphur deficit in soils is likely to increase.

The current worldwide deficit for sulphur is approx. 9.5 million tons. Fertilizer producers in America, Europe and Asia are producing direct application materials based on elemental sulphur to satisfy the sulphur deficit and seize market opportunities. Assuming that 15% of projected deficit is captured (a conservative estimate) sulphur fertilizer demand could increase by 1.5 million tons per year over the next decade.

Multi-cut grass for silage has been shown to be highly susceptible to sulphur deficiency, and yield responses to sulphur of between 5 and 30% are common. For cultivation of fodder crops (grasses) in the Netherlands an official sulphur fertilizer recommendation is given by "Commisie Bemesting Grasland en Voedergewassen".

Oilseed rape is also susceptible to sulphur deficiency, and sulphur fertilisation can produce a dramatic yield response under deficiency conditions. Sulphur deficiency in oilseed rape has been widely reported in France, Germany, Denmark and the UK. Although cereals have a lower requirement for sulphur, yield responses to sulphur application of between 5 and 30% have been obtained in France, and also increasingly in the UK and Germany. In general, field trials across different countries have shown that oilseed rape responds to sulphur applications up to 30 kg S/ha, cereals up to 20 kg S/ha, and grass between 20 and 40 kg S/ha.
  • More than 75% of agricultural land is deficient or likely deficient.
  • Almost all trials responded to sulphur fertilizer with crop yield increases from 14 percent to 60 percent.
  • Optimum sulphur fertilizer dose varied between 30 and 45 kg/ha.
  • Economic returns from sulphur fertilizer use were very attractive.
Like nitrogen, phosphorus and potassium, sulphur is one of the essential plant nutrients. It contributes to an increase in crop yields in three different ways: 1) it provides a direct nutritive value, 2) it provides indirect nutritive value as soil amendment, especially for calcareous and saline alkali soils, and 3) it improves the use efficiency of other essential plant nutrients, particularly nitrogen and phosphorus. In general, sulphur has similar functions in plant growth and nutrition as nitrogen.

The incidence of soil sulphur deficiency has rapidly increased in recent years. Three major factors are responsible for increased sulphur deficiency: a) intensified cropping systems worldwide demand higher sulphur nutrient availability; b) increased use of high-analysis, sulphur-free fertilizers, and c) reduction of sulphur dioxide emissions, particularly in developed regions, reduces atmospheric sulphur deposition, a "natural" sulphur source.

All of the minerals and elements you'll find in Super Sulphur Plus™ come directly out of the ground at a single excavation site in Nevada where they occur together natually in layers.

Super Sulphur Plus™ is not chemically combined or manufactured like inorganic commercial fertilizers and supplements.

Why pay up to $700.00/ton for individual soil supplements (like elemental sulphur, Potash, Gypsum, etc.) when you can get Super Sulphur Plus™ at the source for a fraction of the cost, year-round?
