40 Years of Independent Field Research
Most farms waste 20–30% of every chemical application to drift, runoff, and poor soil penetration. At $11.80 per acre, our proven input program recovers it — with documented net gains of $58+ per acre on corn.
The Science
Water has a natural surface tension of 72 dynes/cm. On waxy plant leaves and compacted soil, it beads up, runs off, and evaporates — taking your expensive inputs with it. APSA-80 cuts that tension to under 29 dynes/cm at just 5 oz per 20 gallons of spray solution.
Water's normal surface tension beads on waxy leaves and compacted soil. APSA-80 reduces it by more than half, causing spray to spread and penetrate instead of running off.
A corn root tip exerts up to 400 psi. A common compaction layer requires 900 psi to penetrate. APSA-80 draws water deeper — roots follow the moisture through the compaction layer, creating new soil pores.
Acts as an activator adjuvant for post-emergent herbicides. In atrazine studies on corn, crabgrass control increased from 57% to 86%. APSA-80 also keeps pesticides in suspension, reducing separation in the tank.
Nutriplant AG's 6-4-3 NPK formula plus 16 peptides and amino acids is applied at critical growth stages when crops need the most support. Complements — never replaces — your existing NPK program.
In sandy soils, APSA-80 increases sorptivity by 70% — holding moisture and nutrients in the root zone longer. In clay, it penetrates fissures to get water moving again. Works across the entire soil spectrum.
Tested by 41 leading universities and 28 independent agricultural stations across 30 states, 5 provinces, and 8 countries. The Irrigation Research Foundation (IRF) in Yuma, CO has conducted multiple multi-year yield studies.

What Growers Say
I've been using APSA-80 for over 20 years. Since we are on strict water rationing, the fact that I can still achieve 200+ bushels of corn with 2–3 acre-inches less water is critical. My average return on investment is at least $60 per acre.
I ran test plots and after positive results recommended trial plots on selected farms. One pecan farm with compacted soil — irrigation used to take nearly 80 hours. After using APSA-80 it reduced to 20 hours. Water savings was about 40% and yields increased by 20%.
In a four-year, two-site study, APSA-80 resulted in significantly increased root depth and crop yield. Corn root depth measured 90%. Root volume increased from 25 to 56% and corn yield increased from 13 to 17%.
Application Reference
| Application | Rate | Mixing Order | Notes |
|---|---|---|---|
| Standard herbicide tank mix | 2.5–5 oz per acre in 20 gal water | Water → herbicide → APSA-80 last | Reduces drift and improves leaf coverage |
| Post-emergent (contact) | 2.5–5 oz per 20 gal | Standard order | Critical for contact herbicides — coverage is everything |
| Post-emergent (systemic) | 2.5–5 oz per 20 gal | Standard order | Glyphosate: extended control 10 weeks vs 5% without |
| 2,4-D applications | 2.5–5 oz per 100 gal | Herbicide first | Caution: increases efficacy — read label for crop phytotoxicity risk |
| Aerial spray (herbicides) | 0.5–1 oz per 3 gal | Add to solution | Reduces aerial drift significantly |
| Insecticides / fungicides | 2.5 oz per 100 gal | Chemical first | Improves coverage on both growing and harvested crops |
| Situation | Rate | Method | Expected Result |
|---|---|---|---|
| Standard irrigation aid | 2.5–5 oz per 10 gal water per acre | Pre-irrigation soil wet or injector | 44% increase in water infiltration (IRF) |
| Center pivot systems | Injector pump — correct dose per acre | Inject during initial irrigation phase | More uniform field coverage, less runoff |
| Overhead sprinkler | Same as center pivot | Injector at ¼ inch water per acre rate | Improved soil penetration across field |
| Sandy soil (leaching problem) | Standard irrigation rate | Pre-irrigation application | 70.5% increase in soil sorptivity — holds moisture in root zone |
| Clay soil (penetration problem) | Standard irrigation rate | Pre-irrigation application | Surface tension drop 72→30 dynes — penetrates clay fissures |
| Situation | Rate | Method | Expected Result |
|---|---|---|---|
| General soil compaction | 15–45 oz per acre in 20 gal water | Soil wet application before irrigation | Roots penetrate compaction layers; new soil pores created |
| Severe compaction layer | 45 oz per acre | Saturate the compaction zone | USDA study: root depth +90%, root volume 25→56% |
| Early season application | 15–30 oz per acre | With pre-emergent herbicide pass (saves a trip) | Roots establish deeper before summer heat stress |

Municipal & Institutional
Municipal grounds crews run herbicide programs across parks, roadsides, and public spaces every season. APSA-80 makes every gallon of chemical work harder — reducing repeat applications and cutting costs per acre treated.
Your crew already budgets for herbicide, fuel, and labor per spray pass. Adding APSA-80 at $2.04/acre means better weed control, fewer re-applications, and less chemical waste — typically paying for itself within the first season.
Most municipalities can purchase under standard small vendor or supply agreements. No complex bid process required for initial trial quantities. We'll walk you through the process — contact us for a direct consultation with your Parks or Public Works director.
