Why the first 90 days decide a plantation’s yield

Nursery seedlings grow fast and use up soluble fertilizer just as fast. A controlled-release blend keeps nutrients available for the whole nursery cycle, with fewer top-ups and more even plugs.

Five seasons of side-by-side plots show where pine responds to nutrition at planting, and where it does not. A summary of the results and what we changed because of them.

On sloped sites, broadcast fertilizer washes away with the first heavy rain. Placing nutrients in the root zone keeps them where the tree can use them, and out of nearby streams.

A young tree’s demand for nitrogen, phosphorus and potassium changes month by month. How release curves are designed to follow that demand instead of front-loading it.

From the first soil sample to the final measurement: how a GOP trial runs, the checkpoints along the way and the data growers receive at each step.

Same product, two ways of applying it. A trial in KwaZulu-Natal compared survival and early height growth with fertiliser in the planting hole or on the surface.

Survival counts are simple to take and easy to get wrong. How our field teams measure survival at 3, 6 and 12 months, and why the timing changes the result.

When planting cannot wait for the rains, every gram of water and nutrient counts. Field data from dry-season plantings shows which practices made the biggest difference.

Before a trial goes into the ground, an independent board of foresters and scientists checks its design. The questions they ask, and why they sometimes send it back.
