For regions where seedlings must be raised with limited irrigation, such as during prolonged dry seasons or in sandy soils, we propose a combination of the biodegradable superabsorbent polymer “EF Polymer<\/a>” and a root-zone water retention process based on local verification. Starting with demonstrations in Nigeria, we are driving global expansion into the agriculture, afforestation, and greening sectors.<\/p>\n\n\n\n

The Water Shortage Challenge of “Prolonged Dry Seasons \u00d7 Sandy Soil” Occurring in Nigeria<\/h2>\n\n\n\n

As dry seasons lengthen and rainfall becomes unpredictable, limited irrigation is absorbed by sandy soil before reaching the root zone, making survival rates and growth unstable. Securing and efficiently utilizing agricultural water has become urgent. Even if the irrigation volume is increased, water escapes in sandy soil, leading only to soaring costs.
\u25cf Scenarios where this becomes apparent:<\/strong> Overseas farmland and afforestation sites. Backed by the prolongation of dry seasons due to climate change.
\u25cf Main impacts:<\/strong> Decrease in seedling survival rates, uneven growth, and deterioration of crop yields and afforestation success rates.<\/p>\n\n\n\n

Why Increasing Irrigation Does Not Solve the Problem: Dual Factors of Natural Elements and Soil Physical Properties<\/h2>\n\n\n\n

In addition to natural factors (prolonged dry seasons and unpredictable rainfall), the water retention capability of sandy soil is low, making it impossible to retain water in the root zone.
\u25cf Grounds for identification:<\/strong> Observations at local fields and control test data.<\/p>\n\n\n\n

Countermeasures Attempted So Far and Their Limits<\/h2>\n\n\n\n

Increasing irrigation volume (limited by water costs and labor) and water-retaining mulch materials (washed away by wind and rain).
Based on these limitations, we adopted the following approach as a more fundamental solution.<\/p>\n\n\n\n

Solution Approach: EF Polymer \u00d7 Local Control Tests \u00d7 Packaging of the Application Process<\/h2>\n\n\n\n

Proposing a new material (biodegradable superabsorbent polymer) combined with collaboration between overseas bases and partner trading companies, and designing a root-zone water retention process based on local verification (control tests).<\/p>\n\n\n\n

Fuji Chemi Trading’s Supply System: Headquarters \u00d7 Overseas Bases \/ Overseas Partner Trading Companies \u00d7 Partner Manufacturers<\/h2>\n\n\n\n

This solution is established through a clear division of roles among multiple bases:
\u30fbHeadquarters \/ Sales: Project promotion and inquiry contact window
\u30fbOverseas Bases<\/a> \/ Overseas Partner Trading Companies: Local sales and distribution
\u30fbPartner Manufacturers: EF Polymer supply and physical property data provision
\u25cf Supply System:<\/strong> Verification in local fields \u2192 Packaging and supplying the application process.<\/p>\n\n\n\n

Results of Implementation<\/h2>\n\n\n\n

Soil water retention capability is improved, stabilizing seedling survival and crop growth even with limited irrigation.
\u25cf KPI Candidates:<\/strong> Improvement in survival rate \/ Growth volume per unit of irrigation \/ Crop yield \/ Afforestation success rate.
\u25cf Implementation Lead Time:<\/strong> Phased operation from local verification to establishing the application process and formal implementation.<\/p>\n\n\n\n

Anticipated Ripple Effects and Horizontal Expansion<\/h2>\n\n\n\n

The benefits of implementing this solution extend beyond solving the primary issues. Please utilize this as material for internal and management proposals.
\u30fbOpportunities to participate in ODA and international organization (FAO, JICA, etc.) projects
\u30fbExpansion into sectors other than agriculture (greening, turf, urban heat island countermeasures)
\u30fbSince EF Polymer is biodegradable, it serves as a strong appeal for “plastic-free” and “prevention of soil contamination”
\u30fbBrand enhancement through connection with climate change adaptation and SDGs (Goals 2, 6, 13, and 15)<\/p>\n\n\n\n

Differences from Competitors: Why Fuji Chemi Trading is Chosen<\/h2>\n\n\n\n

Trading companies exporting polymers standalone have thin on-site verification know-how. Fuji Chemi can provide a one-stop service of “material supply + local control tests + application process design.”<\/p>\n\n\n\n
