Microclimate Root Zone Management
Modified Biomass Microclimate Temperature Control
Patented modified-straw mulching precisely lowers root zone temperature by 2–5°C — enabling heat-sensitive crops like passion fruit and tomatoes to thrive through summer and extend harvest periods.
The Problem
Excessive Root Heat — The Silent Summer Killer
High root zone temperatures suppress root vitality, trigger soil-borne disease outbreaks, and cause premature senescence. Conventional shade nets and mist-cooling treat symptoms but leave the root zone unprotected.
Root Zone Heat Stress
Summer root zone temperatures can exceed 35°C, severely impairing root hair activity and nutrient/water uptake.
Heat-Induced Disease
High temperatures accelerate soil-borne pathogen proliferation, causing concentrated outbreaks of soft rot and root rot in summer.
Shortened Harvest Window
Heat stress accelerates plant senescence, drastically shortening the summer harvest period for high-value crops such as passion fruit and tomatoes.
Over 70% of Taiwan's summer field and protected-cultivation growers cite heat as the primary cause of yield loss — a challenge demanding a root-level solution.
Existing Solutions & Their Limits
Why Conventional Cooling Falls Short
Shade nets, misting, and plastic mulch address above-ground conditions but fail to solve the root-level heat problem.
The Agriens Solution
Patented Modified Straw: Root-Level Precision Cooling
Agriens transforms agricultural waste straw into a high-performance root zone microclimate regulator — combining insulation, moisture retention, and aeration in a single natural material.
STEP 01
Modification Treatment
Straw undergoes a patented modification process that enhances thermal insulation and decomposition resistance, ensuring sustained performance throughout summer.
STEP 02
Field Application
Modified straw is evenly spread around the crop root zone, forming a natural insulating layer that blocks direct solar radiation from heating the soil.
STEP 03
Season-Long Monitoring
Paired with soil temperature sensors, root zone temperature is continuously monitored to ensure cooling targets are met and coverage is replenished as needed.
Technology Advantage
2–5°C Root Cooling. Measurably Extended Harvest.
Modified biomass mulching outperforms conventional cooling methods across every key metric.
