Plantation calculators and tools
This is a free set of planning tools for Philippine plantation managers and agronomists working with tropical cover crops and soil conditioners. Each tool uses conservative, literature-based defaults and is built around the crops and conditions found under oil palm, rubber, coconut, durian, and similar systems across Mindanao, the Visayas, and Luzon. Use them to size a cover crop programme, then confirm with our agronomy team before scaling across an estate.
The tools
- Climate suitability checker: ranks Mucuna bracteata, Pueraria javanica, Calopogonium, and Centrosema by region and elevation to shortlist the best species for your site.
- Nitrogen fixation and urea credit calculator: estimates nitrogen fixed per hectare and a conservative urea-equivalent credit.
- Soil erosion calculator: uses the RUSLE method to estimate soil loss and the reduction an established cover crop can provide.
- SoilBoost EA application rate calculator: turns a target rate into a total product quantity by crop, area, and method.
- Agricultural unit converter: converts area, weight, and per-area rates such as kilograms per hectare.
Frequently asked questions
Are the tools free to use?
Yes. All of the calculators and the converter are free and require no account.
How accurate are the results?
They are planning estimates based on published tropical-plantation data, not site measurements. Use them to compare options and size a programme, then validate with soil and field testing.
Can your team help me apply the results?
Yes. Tell us your crop, area, and region and our agronomy team will recommend a species mix, seeding rate, and programme. You can request a consultation or contact us for a quote.
