Horizon A
Soil Adjuvant for Moisture Retention Root Zone Control Active Availability Evaporation Mitigation
Keep your actives in the critical root zone
Powered by proprietary hydrocolloid technology, Horizon A® is a next-generation soil adjuvant that improves the performance of soil inputs when applied through ground equipment or irrigation systems. By holding moisture and active ingredients in the root zone, Horizon A facilitates consistent control, improved efficacy, and a stronger crop response.
Multi-pronged approach
Built to Control What Happens Below the Surface
- 1
Root Zone Retention
Horizon A prevents excessive downward movement of water and tank mix ingredients from ground or irrigation-applied inputs, keeping actives concentrated in the upper soil profile where roots are most active. This increases the amount of chemistry and moisture available for uptake instead of being lost below the root zone.

Improve Moisture Management
By reducing evaporative and moisture-related loss at the soil surface, Horizon A helps maintain a more stable moisture environment around the root system. Consistent soil moisture improves plant access to inputs and supports better performance of systemic products.

Enhanced Uptake & Performance
Holding actives and water in the root zone allows plants to absorb more of what is applied. Horizon A improves the effectiveness and persistence of soil-applied herbicides, insecticides, fungicides, nematicides, nutrients, and fertilizers under variable soil and environmental conditions.

Boost Performance in Arid Soil
For regions with sandy, sandy-loam, and loam soils, water holding capacity is limited. Horizon A helps keep applied crop inputs in the root zone, reducing positional loss and minimizing movement toward groundwater. This creates an environment where actives can perform despite environmental factors.

Horizon A has the potential to reshape how growers think about and use soil-approved crop protection tools, while improving the efficiency of limited irrigation systems. Water use planning is one of the most critical challenges growers face today, and Horizon A helps protect and recover crop production during periods of stress.Travis KiddField Development Manager, Attune Agriculture
