Evidently better forestry nutrition
Every species, site and operation brings different nutritional demands. Our commercially validated trials provide a solid grounding for informed decisions, while ongoing R&D explores new approaches.
We continuously improve and refine nutrition programs with forestry teams and researchers, using trial findings to optimize practical performance and value per hectare.

Future Potential
Every field trial adds to what we know. And every result raises new questions. We want to better understand how different tree species respond to nutrition, and why performance can vary between sites. In upcoming research, we will explore these differences in more detail, building on what we have already learned in the field.
Establishment remains a key focus, while we also explore nursery nutrition and later rotation stages where relevant. Each new finding helps us identify opportunities for improvement and refine our nutrition optimization programs. We’ll share new trial results in Q1 2027.
Commercial validation trials
Our commercial validation trials show how Forest3 nutrition solutions perform compared with conventional forestry fertilization practices, under real plantation conditions. We measure early tree growth and, where available, nutrient use efficiency across different species and sites.
Each trial provides measurable results under specific field conditions, helping forestry teams evaluate fertilizer performance and make informed nutrition decisions.

“We found Forest3 Rootzone easy to use and cost-efficient. Placing its NutriBags directly in the planting hole saved time and labor, with no root damage observed. We achieved canopy closure in line with our previous fertilizer regime, while using less than one-fifth the fertilizer.”

“Over the past three years, we have combined our understanding of plant nutrition and tropical plantation forestry to create a product development pipeline that we hope will provide the industry with better nutrition options in the future.”

“Forest3 Rootzone, marketed as NuTreebag in Sub-Saharan Africa, is applied through its NutriBags in a single operation at planting. We have seen better tree health and growth, even 12 months after planting. When you calculate total system costs, NuTreebag is more cost-efficient than conventional fertilizer.”

“Forest3 Rootzone significantly outperformed the other products in our field trials, with a visible height gain of 20 to 25%. Being able to plant and fertilize in one operation was a major game-changing achievement, helping us eliminate operational inefficiencies.”
