KansasAnother name for Polyaspartic acid:
Amisorb™ is a NanoChem Solutions trademark for polyaspartic acid used in Wisconsin by Jay-Mar. Jay-Mar is the exclusive distributor for the product in Wisconsin.

Here is a summary of some research on it:
Several years ago, a product called Amisorb was introduced by the Amilar Corp. of Chicago, Illinois as a soil additive to enhance nutrient uptake and increase crop yield. The compound was originally used to prevent scale in boilers and is chemically related to Nutrasweet. According to the company, Amisorb increases nutrient uptake by artificially increasing root branching and root hair development. Recommended rates with the product are 1 - 2 quarts per acre mixed with liquid fertilizer, impregnated on dry fertilizer, or applied directly to the soil. Recently, Keith Kelling, UW Soils Extension Specialist, summarized all of the research to date on Amisorb and the results are presented here.

Research results to date

Early research with Amisorb in a hydroponic greenhouse environment showed positive results with both increased nutrient uptake and tillering in wheat.

During the past three years, a number of field research trials (nearly 100 site-years ) have been conducted on corn, soybeans and winter wheat. Although yield increases were observed in about 27% of the corn and wheat experiments, the overall yield change from the addition of Amisorb remained relatively small (+1.75 bu/a for corn and +1.07 bu/a for wheat ). Average responses for the with or without Amisorb in the various corn experiments ranged from -8.1 to +13.6 bu/a. Wheat responses ranged from -5.7 to +4.6 bu/a. Results with soybeans have been less encouraging than with corn or wheat.

Amisorb is not a cheap product to use at a price of around $7 to $8 per quart. Because research to date cannot adequately define when growers are likely to see a significant yield response, it is probably prudent to save your input dollars or use the product on a limited basis where yield comparisons can be made.

Polyaspartic acid (PASP) is an eco-friendly biopolymer that is gaining popularity in various fields including agriculture. It is synthesized by condensing aspartic acid through a heat treatment process. Due to their exceptional properties such as high water solubility, high chelating ability, and biocompatibility, PASP can be used in a wide range of applications.

Here, we will explore the application of polyaspartic acid in the field of agriculture.

1. As a chelating agent

One of the significant advantages of PASP is its chelating ability. Polyaspartic acid(PASP) can form complexes with a variety of metal ions, including calcium, magnesium, and ammonia. By chelating these metal ions, PASP can be used to mitigate the negative effects of soil salinity, alkalinity and calcium deficiency on crop growth. Studies have shown that applying PASP to soil can significantly reduce soil salinity, increase the availability of nutrient ions, and increase crop yields.

2. As a plant growth promoter

Polyaspartic acid(PASP) is also known for its ability to stimulate plant growth, a crucial aspect for farmers. Polyaspartic acid(PASP) promotes plant growth through its action as an antioxidant, stress reliever and enzyme activator. In addition, it enhances the ability of plant roots to absorb essential nutrients, resulting in healthier plants and higher yields.

3. As a herbicide enhancer

Polyaspartic acid(PASP) have been found to significantly enhance the efficacy of herbicides. Mixing PASP with herbicides reduces spray drift, improves herbicide retention on foliage, and increases herbicide penetration into plants. Farmers can reduce the environmental and economic costs of farming by reducing the amount of herbicides needed to effectively control weeds.

4. As a soil conditioner

Polyaspartic acid(PASP) can also be used as a soil conditioner. When added to soil, it improves soil structure, moisture retention, water infiltration and nutrient availability. It also enhances microbial activity in the soil, increasing soil fertility and overall soil health. By improving soil quality, PASP helps reduce soil erosion, increase soil productivity and promote sustainable agriculture.

5. As a post-harvest treatment

Polyaspartic acid(PASP) can be used as a post-harvest treatment of crops to extend their shelf life. It acts as a natural preservative that inhibits the growth of spoilage microorganisms while maintaining the quality and nutritional value of crops. Applying PASP to fruits and vegetables prior to storage can significantly reduce post-harvest losses and extend the life of the produce.

In conclusion，Polyaspartic acid(PASP) is a multifunctional and environmentally friendly biopolymer that can be applied in various fields including agriculture. Its chelating ability, plant growth promoting properties, herbicide enhancing properties, soil conditioning and post-harvest treatment applications make it a valuable tool for farmers. By incorporating PASP into their farming practices, farmers can improve crop efficacy, reduce costs and promote sustainable farming.
