AgSAP® - Agricultural Super Absorbent Polymer

Super absorbents that are specifically designed for agriculture and water conservation in soil.  The first US Patent for a super absorbent was awarded in 1961 for an agricultural application!

AgSAP® (Agricultural Super Absorbent Polymer), is a Potassium-neutralized acrylic-acrylamide co-polymer that withstands numerous wet/dry cycles.  The product releases moisture to plant root hairs and is replenished as a water reservoir whenever the soil receives rain or water irrigation.

Water Conservation Technology for Sustainable Agriculture

AgSAP® (Agricultural Super Absorbent Polymer) represents a significant tool in agricultural water management, delivering advanced soil amendment technology for water conservation and crop productivity. This potassium-neutralized acrylic-acrylamide co-polymer transforms how plants access water, creating a sustainable reservoir system that can reduce irrigation needs by up to 50% while improving crop yields and soil health.

Proven Science, Exceptional Results

Building on over 60 years of superabsorbent innovation—the first US patent for agricultural superabsorbents was awarded in 1961—AgSAP® delivers unmatched performance through its unique wet/dry cycle durability. Unlike conventional water retention products that degrade quickly, AgSAP® maintains its water-holding capacity through numerous irrigation and weather cycles, providing years of consistent performance in soil.

Agricultural SAP® (AgSAP®) - FAQs

What is AgSAP® and how does it work as a soil amendment?
AgSAP® (Agricultural Super Absorbent Polymer) is a potassium-neutralized acrylic-acrylamide co-polymer formulated for use as a soil amendment. When mixed into soil, AgSAP® particles absorb water during irrigation or rainfall, swelling into a hydrogel reservoir in the root zone. As the surrounding soil dries, plant root hairs draw moisture directly from the swollen polymer particles. When the soil is rewatered, the particles rehydrate and the cycle repeats — providing a long-lasting water reservoir that reduces irrigation frequency and supports plant health between waterings.
Field applications and studies indicate that AgSAP® can reduce irrigation requirements by up to 50% in suitable crops and soil conditions. The actual reduction depends on soil type, crop, climate, and application rate. Sandy and loamy soils that drain quickly show the greatest improvement. Contact M² Polymer Technologies for application rate recommendations tailored to your specific crop and regional conditions.
AgSAP® is engineered to withstand numerous wet/dry irrigation cycles while maintaining its water-holding capacity over multiple growing seasons. The potassium-neutralized co-polymer chemistry provides durability through repeated swelling and desorption cycles. Unlike conventional water-retention products that degrade within a season or two, AgSAP® provides multi-season performance. Actual useful life depends on soil pH, mineral content, and climate; contact us for guidance on your specific environment.
Yes. AgSAP® uses potassium-based neutralization chemistry that is fully compatible with soil and plant root systems. Potassium is an essential macronutrient for plant growth, making it an agronomically appropriate ion choice. The polymer does not introduce harmful compounds into the soil, is not absorbed by plant tissue, and is not transferred to the food product. Safety Data Sheets are available in the Resources section of our website.
Application rates vary by soil type, crop, and irrigation method. Typical rates range from 10 to 40 pounds per acre for field crop applications; container and nursery applications may require different rates. Multiple particle sizes are available to match different mixing and application methods. A bench-scale soil test is strongly recommended before large-scale application. Contact M² Polymer Technologies for a free technical consultation and specific application guidance.
The first U.S. patent for a superabsorbent polymer was awarded in 1961 specifically for an agricultural application making agricultural SAP one of the oldest established uses of this technology. M² Polymer Technologies’ AgSAP® builds on over 60 years of agricultural SAP science, delivering a modern potassium-neutralized formulation optimized for today’s irrigation efficiency and sustainable agriculture challenges.

AgSAP® is compatible with most standard granular and water-soluble fertilizers. Because the polymer retains water in the root zone, it can also help retain water-soluble nutrients near plant roots, potentially reducing fertilizer leaching in sandy and high-drainage soils. However, high salt concentrations from certain fertilizers can reduce SAP absorption capacity, so we recommend testing combined applications before large-scale use. Contact our technical team for specific compatibility guidance.
