SoilBoost EA for Durian and Tropical Fruit Trees
What Is SoilBoost EA?
SoilBoost EA is a concentrated humic acid soil conditioner manufactured exclusively by Chemiseed Sdn. Bhd. and derived from Leonardite ore, designed to improve nutrient cycling in tropical agricultural soils. Its humic and fulvic molecules chelate micronutrients (iron, zinc, copper), raise the soil's cation exchange capacity, and support root activity, improving the availability and uptake of nitrogen, phosphorus, potassium, and micronutrients. Unlike synthetic fertilizers that provide nutrients directly, SoilBoost EA works by improving soil structure and nutrient availability so existing soil nutrients become more accessible to plant roots. SoilBoost EA is exported worldwide with phytosanitary certification (ISPM 7 compliant).
SoilBoost EA Application Rates
Rates depend on how SoilBoost EA is applied. The figures below are the standard method-based rates used across all SoilBoost EA guidance. Use the calculator further down to work out the exact quantity for your crop, area, and method.
| Method | Rate | Best for |
|---|---|---|
| Per mature tree (soil drench at drip line) | 100-200 g per tree, 2-3x per year | Durian, mango, coconut, oil palm, and other established trees |
| Per planting hole (at planting) | 20-50 g per hole | New tree and seedling establishment |
| Fertigation / soil drench | 10-15 kg/ha | Banana, papaya, vegetables, and field crops via irrigation |
| Broadcast / pre-planting (dry) | 50-100 kg/ha | Whole-block incorporation before planting |
| Foliar spray | 500-1,000 ppm solution | Quick top-up between soil applications |
Why Durian Growers Use SoilBoost EA
Durian trees are particularly responsive to soil management. The root system of durian is relatively shallow and benefits from good root-zone conditions and steady nutrient availability. SoilBoost EA improves soil structure and supports beneficial soil microbial activity around the root zone. Growers across tropical regions report improved fruit set and more consistent fruit quality when SoilBoost EA is included in their soil management program alongside conventional fertilizers.
Key benefits for durian include improved nutrient uptake efficiency (allowing potential reduction in synthetic fertilizer rates over time), better soil structure and water retention in the root zone, support for beneficial soil microbial activity in the root zone, and compatibility with organic and conventional management systems.
How to Apply SoilBoost EA
For tree crops, apply about 100 to 200 g per mature tree. Dissolve in water (ratio of 1:100 to 1:200) and apply as a soil drench around the drip line of the tree. The drip line is the outer edge of the canopy where rainwater naturally falls. This is where the active feeder roots are concentrated.
For field crops like melon and vegetables, apply at 10 to 15 kg/ha via irrigation (drip or sprinkler) or as a foliar spray during early morning or late afternoon.
Timing: apply during the early wet season when soil moisture is adequate and soil temperatures are warm (above 20 degrees C). Avoid applying during heavy rain events that could wash the product away before soil absorption.
