FIELD SCENARIOS / 02

Start with the growing context

Use crop, growth stage, growing medium and water management information to decide whether further assessment is appropriate.

Root-zone material placement during tree transplanting — **Tree transplanting and root zones**Review root treatment, placement and transplant management

Illustrative seed coating or pre-sowing treatment — **Seed and seedling treatment**Confirm treatment methods and ratios against product-specific instructions

Illustrative root-zone material application on sloping land — **Sloped planting areas**Assess terrain, runoff, soil and irrigation conditions

PRODUCT GRADES / 03

Particle sizes for different applications

Three sample appearance categories. Actual particle-size distribution follows the specifications for the model and batch.

01 / COARSE

Coarse

Larger particles

Illustrative appearance is approximately 1.5–2 times the medium sample size. Confirm actual distribution for the relevant model and batch.

02 / MEDIUM

Medium

Mid-size particles

Between fine and coarse samples. Confirm actual particle distribution against model and batch records.

03 / FINE

Fine

Fine powder-like appearance

Typically the higher-priced discussion category. Confirm pricing for the model and order conditions.

Particle-size images are appearance references; formal specifications follow the relevant model and batch. Select a suitable category for the crop, growing medium, water quality and application method.

Match the full application context

Consider crops, area, growing medium, water quality, application method and purchasing logistics together. Assess material, application, irrigation, labor and transport inputs against water and nutrient management goals, seeking a practical and appropriate solution.

WATER ABSORPTION / 04

Absorb water Form a hydrated gel

On contact with water, hydrophilic groups take up moisture and the crosslinked network expands into a hydrated gel. Absorption and release depend on the formulation, water quality, salinity, growing medium and test conditions.

The diagram explains the general water absorption and release mechanism of SAP. Background research: Scientific Reports and Agronomy

General SAP absorption, swelling and water release illustration — General mechanism illustration | Performance depends on the product and test conditions

ROOT-ZONE WATER EXCHANGE

How does stored water interact with the root zone?

Swelling is only the starting point. Water exchange between gel, soil pore water and roots depends on water potential, salinity, soil conditions and formulation. Assess absorption, release and the actual root-zone environment together.

PRODUCT IN USE / 05

Understand absorption and application

Explore the change from dry granules to gel, then review possible root-zone handling and application methods. Follow model-specific instructions and project conditions.

APPLICATION GUIDE

Placement depends on the application

Field crops and tree transplanting involve different placement, depth and operations. Define the crop, growth stage and site conditions, then review model-specific instructions.

Field cropsDiscuss mixing, placement and field operations for the planting method

Tree transplantingReview root-zone placement, depth and transplant management

Confirm dosageVerify dosage against the model, crop conditions and supporting information

Any dosage or depth in a reference image is not a Funder product recommendation. Confirm instructions for the model, crop and local conditions before use.

MATERIAL & STRUCTURE / 06

Polymer structure and attapulgite

Structure diagrams explain general composition and porosity. Product-specific ingredients, proportions and functions require formulation and test records.

APPLICATION CONTEXT / 07

Four application conditions we review with you

Crop and stageCrop type, root environment and project stageYou share the crop and stage so we understand the context

Soil and growing mediumMedium, texture, salinity and planting methodWe review applicable conditions against the growing medium

Water and irrigationWater quality, irrigation and management backgroundYou describe water quality and irrigation practices

Evaluation goalsMetrics, duration and verification methodTogether we discuss metrics and verification evidence it

Choose the model and application method for your growing conditions, starting with a small-scale trial. Refer to the relevant product tests and application information for expected performance.

APPLICATIONS BEYOND CROP PRODUCTION

Saline conditions, land rehabilitation and slope revegetation

Tell us about the site, not just the crop. We review the SAP formulation and a small-scale trial with you before considering wider use.

Saline–alkaline sites

Select a suitable formulation based on soil EC and pH, irrigation-water salinity and drainage. Salinity affects absorption; use SAP alongside the site’s salt-management and soil-improvement measures.

Degraded-land rehabilitation

Discuss root-zone moisture support for seedling establishment on dry or degraded sites. Species selection, soil preparation, water supply and environmental suitability remain part of the project.

Slope revegetation

Review planting substrate, root-zone placement, access for irrigation and follow-up care. SAP is a possible moisture-management component, not a substitute for erosion control or slope-stability engineering.

Select a suitable approach for the site, starting with a small-scale trial. Use plant establishment, irrigation needs and maintenance costs to guide wider application.
