Economical and Responsible Liquid Sulfur Fertilizer

accesS™ is our high-efficiency liquid sulfur fertilizer. Our formula allows plants to more efficiently absorb sulfur and keeps more plant-usable sulfur in the soil. At the same time, accesS uses a lower concentration of sulfur at lower rates, but provides the same or better results compared to commodity fertilizers. This makes it an economical and environmentally responsible choice.

accesS may be applied anywhere five or more pounds of elemental sulfur are required. The unique Nutriq Technology makes accesS more efficient than other sulfur fertilizers, and therefore requires a lower rate. This prevents the sulfur and other nutrients from being tied up in the soil, which also prevents environmental damage from nutrient toxicity.

Sulfur deficiency symptoms appear very similar to nitrogen deficiencies, including yellowed leaves and stunted growth. However, symptoms of a sulfur deficiency will appear on young leaves, while nitrogen deficiencies show on older leaves. Repeated application of other nutrients can create an imbalance in the soil and introduce a sulfur deficiency. This makes regular soil testing particularly important for maintaining optimal yield and reaching full growth potential.

accesS can be used to correct sulfur deficiencies at planting, or anytime throughout the year. Consult with an agronomist to find the best nutrient program and application method for your crops, soil, and climate.

Have us design a custom nutrition plan for you

An AgroLiquid nutrition plan is dependent on your location, climate, soil conditions, and goals with your crop. All of our tailored programs start with reviewing your soil samples with one of our expert agronomists. After our analysis, our team will provide you with a couple options that will help you meet your goals on a budget that won’t break the bank.

AgroLiquid Scientific Advancements

Secondary nutrients like sulfur are just as important as nitrogen, phosphorus and potassium, even if they are needed in smaller amounts. Without secondary nutrients, plants cannot take in and process macronutrients. Our agronomists have carefully studied the use of secondary nutrients in a variety of crops, and developed the ideal combination to increase balanced nutrient utilization.

Nutriq Technology

This bonds with your nutrients and creates a protective layer that makes up to 80% more of your nutrients available to plants. It sounds like magic, but it’s just science.
