Food security is front of mind for us here at Sulvaris recognizing the 0.71 Billion people that do not have sufficient food consumption globally today. Sulfur is a key nutrient that we have engineered to be more efficient and applied more responsibly to increase food production.

Using all plant nutrients effectively is critical for pushing yields higher and getting the best return on your crop investment. This means using the right types of fertilizer to fit within your nutrient management plan. Our latest data on fall applications of MAP+MST® (Iowa, 2023) demonstrates a flexible application timing to achieve high yields in Sulfur responsive sites and reinforces what we have seen in previous years. This flexibility provides growers with additional options for nutrient management, showing suitability for fall or spring application strategies.

Using this data as an example for application this fall, applying MAP+MST® instead of MAP, would result in a 21bu/acre, or $89/acre net gain using current fertilizer prices. This also highlights the critical need for Sulfur in high yielding corn, and the impact of choosing MST® as a Sulfur source for crop nutrition.

Since nutrients were balanced, this tells us that other nutrients like nitrogen were used more efficiently, producing higher yields with the same amount of fertilizer inputs.

*All nutrients were balanced equally between treatments, except for ‘MAP´ which did not receive sulfur. Sulfur was applied at 20lbs S/acre.

AS MST®

A Fertilizer containing micronized elemental Sulphur and Ammonium Sulphate

  • Product available with up to 15% MST® Sulphur
    • AS MST® (17-0-0-36S)
  • AS MST® has improved handling characteristics with strong agronomic performance.
    • This is a high analysis sulphur product, meaning a lower volume of product is required to achieve sulphur requirements in fertilizer blends.
  • Reducing the ammonium sulphate component in blends has the added benefit of reduced caking potential as MST® absorbs less water from the atmosphere.
  • Owing to the elemental sulphur component, AS MST® has a lower salt index per unit of sulphur than ammonium sulphate, which decreases the likelihood of damaging small, sensitive seeds like canola.
  • The combination of immediately available- and slow release-sulphur is ideal in cooler soils. The sulphate component of AS MST® offers immediate sulphur availability in the spring, and the MST® component will transform to sulphate as soils warm through the summer months.
  • In locations of high precipitation, the MST® component also offers added insurance as it will not leach from soils in high rainfall events until it is transformed to sulphate by soil microorganisms.

CCT-AP

Carbon Ammonium Phosphate

A revolutionary carbon-based, ammonium phosphate product

  • Sulvaris seeks to improve N and P use efficiency with a structural carbon enhanced efficiency carrier by pursuing the development of a new proprietary product, CCT-AP
  • Global use efficiency of P fertilizers is currently only ~10-15% in the year of application, far lower than that of N and K(1)
  • P deficiencies can be found in nearly 67% (14.1B acres) of global land designated for crop production(2)
  • CCT-AP product development targets:
    • a source of enhanced efficiency nitrogen and phosphate,
    • an agronomic source of soil organic carbon,
    • a low-CAPEX, accretive investment as a bolt-on unit for existing commercial-scale phosphoric acid/MAP/DAP production facilities

CCT-AS

Carbon Ammonium Sulphate

A revolutionary carbon-based, ammonium sulphate product

  • CCT-AS is a carbon-based granular fertilizer developed by Sulvaris
    • Carbon content 5 – 15%
  • Potential source of enhanced efficiency nitrogen; shown to increase yields
  • Delivers nutrients in carbon matrix form – contributing to Soil Organic Carbon
  • Feedstock includes biomass, ammonia, and sulphuric acid
  • In addition to being a unique, high-value source of crop nutrients, CCT-AS provides an outlet for wood waste or other carbon-based waste streams
  • CCT transforms inexpensive waste feedstock into high analysis fertilizer
    • Potential reduction of soil N2O emissions
    • Potential reduction of soil CH4 emissions
    • Generates CO2 credits

19% N, 21% S, 5% C (19-0-0-21-5C)

SGN: 290-320 (2.9-3.2mm)

Uniformity index > 60

Crushing strength > 4.5 kg (10lb)

HIGH RTA and LOW dust

Flexible process allows for alteration of nutrient analysis and carbon content, as well as the addition of micronutrients

POTASH MST®

A Broad Acre Potash and Sulphur Fertilizer

  • 0-0-49-15S product available with up to 15% sulphur
  • Being a mixture of Potash and elemental sulphur (MST®), Potash MST® offers a multitude of benefits for growers, from improved handling characteristics to strong agronomic performance.
  • With an analysis of 0-0-49-15s, Potash MST® meets the majority of sulphur application requirements without the need for additional sulphur.
  • Once applied to the soil, Potash MST® has excellent dispersal of the MST® component.
  • Differentiate your potash portfolio with a value-added product.

Phosphate MST®

A broad acre phosphate fertilizer containing micronized elemental Sulphur

  • MAP MST® nutrient formulation is 9-43-0-16S (15% MST®)
  • In research trials in North America Phosphate MST® has equal to or greater yield responses than ammonium sulphate.
  • MST® provides three essential plant nutrients (NPS) together within each granule of phosphate MST® for uniform distribution across the field.
  • Phosphate MST® has enhanced blending characteristics over AS and exhibits less caking due to the hydrophobic nature of elemental sulphur.
  • Non-combustible product (confirmed by 3rd party testing lab).
  • Granule hardness, storage and handling properties identical to MAP.

Phos MST® has all three nutrients evenly dispersed through every granule

Advantages

On average, Liquid MST® has provided greater yield responses than ammonium thiosulfate across all site-years studied.

The sulphur in MST® is immobile in the soil until it is oxidized to sulphate.  Liquid MST® has less leaching than ATS and can be readily integrated into fall and early spring applications.

Liquid MST® does not have a high salt or nitrogen component that can damage germinating seeds, or foliage.

This is a high analysis sulphur product, meaning a lower volume of product is required to achieve sulphur requirements.

Liquid MST® is suitable for side dress applications.

Liquid MST® has a lower carbon footprint than tradition sulphur products such as ATS or AS.

Liquid MST® allows all of the crop’s sulphur requirements to be provided from one source, creating an opportunity to choose an environmentally responsible N source.
