Core Technology III

Effervescent Diffusion Fertilizer Technology

Water-activated nutrient delivery engineered for speed. Gas-assisted diffusion disperses nutrients uniformly within seconds of moisture contact — for fertigation, drench, and foliar applications.

Technology Overview

When speed of delivery is the agronomic advantage

Controlled Release Fertilizers solve the over-application problem by extending nutrient delivery over weeks or months. But not every agronomic scenario calls for slow release. Crop stress, deficiency correction, transplant establishment, and precision fertigation programs demand rapid, uniform nutrient availability — ideally within hours or minutes of application.

Nousbo's effervescent diffusion technology addresses this need. Unlike conventional water-soluble fertilizers that dissolve passively (and unevenly), the effervescent tablet format harnesses controlled gas generation to actively disperse nutrients through the solution or growing medium. The result is rapid, predictable, and spatially uniform nutrient distribution — without clumping, stratification, or incomplete dissolution.

Key Differentiation
Active diffusion via gas generation
CO₂ micro-bubbles created during dissolution actively carry and distribute nutrient ions throughout the solution volume.
Zero stratification or settling
Convective mixing from the effervescent reaction prevents nutrient gradient formation, ensuring consistent concentration throughout the tank or drip line.
Precision dosing in tablet/granule form
Pre-weighed tablet format eliminates measurement error, improves on-farm logistics, and allows integration into automated dispensing systems.
Mechanism of Action

Four-stage dissolution and diffusion process

The effervescent fertilizer tablet dissolves in a defined sequence, each stage contributing to the uniformity and speed of nutrient delivery.

1
Water Contact
Tablet contacts water or moist growing medium. Outer matrix begins to hydrate and swell. Moisture penetrates along the tablet's micro-channel structure.
2
Acid-Base Reaction
Internal effervescent components (citric acid + carbonate buffer system) react upon hydration, generating controlled CO₂ gas evolution throughout the tablet body.
3
Nutrient Release & Active Mixing
CO₂ micro-bubbles carry nutrient ions outward from the dissolving tablet matrix, creating convective micro-currents that distribute nutrients radially and prevent localized concentration peaks.
4
Complete Dissolution
Full tablet dissolution achieved within 30–90 seconds at standard application temperatures (15–30°C). Resulting solution is clear, fully chelated, and ready for immediate application or injection into a fertigation system.
Application Methods

Three primary deployment formats

Effervescent diffusion fertilizers are optimized for use cases where speed of nutrient availability and precision dosing are the primary agronomic requirements.

Fertigation & Drip Systems
Tablets dissolve in the fertigation tank within 60 seconds, creating a homogenous nutrient solution with no undissolved particles that could clog emitters or drip lines. Compatible with all standard injection systems, regardless of flow rate.
Greenhouse vegetables Strawberry Blueberry Tomato
Soil Drench & Transplant
Applied as a concentrated root-zone drench at transplanting or during establishment. The effervescent action improves root contact and lateral distribution without the localized salt concentration risk associated with granular fertilizers applied near the root zone.
Transplants Seedlings Turf Nursery
Deficiency Correction & Foliar
Rapid correction of mid-season micronutrient or macronutrient deficiencies via foliar spray or high-rate soil drench. The effervescent dissolution ensures complete solubility and prevents spray nozzle blockage in foliar application equipment.

Crop-Specific Use Cases

Where effervescent diffusion creates the greatest advantage

Effervescent fertilizers are purpose-built for high-value crop systems, controlled environment agriculture, and precision fertigation programs where application efficiency and nutrient uniformity translate directly to yield and quality outcomes.

Controlled Environment Agriculture (CEA)
Greenhouse and vertical farm operations require precise EC and nutrient concentration control. Effervescent tablets dissolve completely with predictable ion ratios, supporting automated nutrient management programs.
High-Value Fruit & Specialty Crops
Berry, stone fruit, and vineyard operations managing multiple fertigation events per week benefit from the reduced preparation time and consistent dissolution that effervescent tablets provide vs. powder or granule products.
Transplant & Plug Production
Nursery and propagation operations applying starter fertilizers at transplant can use effervescent tablets as a precision drench — eliminating weigh-and-measure steps and improving consistency across large transplant operations.
