ProtoHumiX for oil palm plantations.
Liquid inorganic soil improver for Southeast Asia oil palm plantations.
Oil palm plantations in Indonesia and Malaysia face rising NPK costs, soil acidification and declining organic matter. ProtoHumiX addresses all three — typically reducing 30–40% of mineral fertilizer while maintaining FFB yield.
The plantation problem
- • NPK & urea prices have been structurally high since 2022, eroding per-hectare margin.
- • Tropical mineral soils in Sumatra, Kalimantan and Sabah lose organic matter rapidly under continuous cropping.
- • Soil pH drifts to 4.0–4.5 in mature blocks, reducing nutrient uptake and root activity.
- • Conventional foliar fertilizers don't address the root cause of soil degradation.
What ProtoHumiX changes
- • Improves cation exchange capacity — applied NPK is retained, less leaching.
- • Promotes humus formation in the root zone — long-term soil recovery, not just seasonal.
- • Buffers pH back toward the 5.0–6.0 range optimal for oil palm nutrient uptake.
- • Non-microbial — stable in hot climates, no cold chain to plantation warehouse.
Application protocol — oil palm
| Stage | Timing | Dose | Method |
|---|---|---|---|
| Nursery | Every 6–8 weeks | 1–2 L in 1,000 L water | Drench / fertigation |
| Immature palms (1–3 yr) | 3 times/year | 2–3 L/ha | Soil application around palm circle |
| Mature palms (4+ yr) | 2–3 times/year | 3–5 L/ha | Tank-mix with standard fertilizer round |
| Stressed / recovery blocks | As agronomy plan dictates | 5 L/ha | Combined foliar + soil application |
Final protocol is agreed with your agronomy team after a per-block soil review.
