A-grade Paulownia is only achieved if the trees have all side branches cut off 2/3 up the trunk each spring. - and you can actually achieve a trunk height of 7-10 meters with a diameter of 40-50 cm in 10-12 years.

You get D-grade Paulownia if you don't take care of your trees and the side branches therefore make knots in the trunk. This also gives a shorter trunk of 3-5 meters.

3B07 and 3BFE have 25-35 times higher yields on the bottom line than winter wheat on marginal, sandy soil.

And on maximum clay soil approx. 9-12 times greater yield than winter wheat or rapeseed.

Paulownia requires watering for 1-2 years on marginal lands, but can do without IF the capillary tear is sufficient to bind the water in the surface in summer, otherwise it MUST be watered with at least 2 x 2 liters of water weekly during the growing season.

We recommend irrigation at least the first year-

When a paulownia tree has grown to 2 meters in height, the roots have reached a depth of 2 meters, where it is no longer necessary to water.

However, Paulownia does not tolerate overly moist soils with high water levels over 1.3 meter in the summer.

Paulownia roots reach a depth of 12-15 meters after 8 years of growth, and store incredible amounts of Co2 in the roots and in the soil ... where Co2 belongs.

Paulownia die out immediately when using Roundup on the freshly sawn stumps regardless of the age of the tree.

The Paulownia hybrids 3B07 and 3BFE are characterized by vertical and very straight growth. This makes the wood very suitable for furniture production, timber and for plywood.


The tree is extremely wind-resistant and can withstand strong winds throughout the growth period without bending the trunk.

You are amazed at how little the tree sways in the wind.

Paulownia biomass for wood pellets achieves a pressed density of 1250 kg/m3 and a calorific value of approx. 16700 KJ7Kg.

DIVIDEND AND OPERATING COSTS:

REMEMBER: Paulownia is a crop that reproduces itself and can therefore grow in the same place for a minimum of 70 years including a minimum of 7 harvests.

You should expect a construction cost of approx. GBP 6000 - 8000 per hectare. season 2023

PLANT including soil treatment, purchase/installation of drip irrigation system, installation/purchase of weed mats/plastic, purchase of cuttings, planting and watering.

Compared with Spanish, Bulgarian and Japanese yields after 8 years of growth, it is assumed that the yield per hectare in Scandinavia will be 1100-1300 cubic meters per hectare of real timber at the first harvest.

The price per cubic meter of paulownia A-grade timber is 220 EURO in 2022, but it is expected that the price around 2032 will drop to around 150 EURO.

A-grade timber is only achieved by technical pruning every spring after the first 2 growing seasons ... then stemming every spring for the next 6 years, so that 2/3 of the trunk is clear of branches.

It is certain, however, that paulownia for the production of plywood has remained stable at 60 EURO per m3 D-grade paulownia over the past 4 years. This is achieved without descent.

But the calculation per hectare looks something like this:

1000 trees planted in rows 3x3 meters on 1 hectare.

Each tree gives an average of 1.3 m3 at the first harvest = 1300 m3

1 m3 currently costs just 220 EURO x 1,300 m3 = 286000 EURO for the first harvest after 10-12 years = aproxEURO 26000 per year.

We expect the price to be around GBP 130 per m3 when we are in 2032, and by that time the plantation will provide

1300 m3 x 130 = GBP 169000 from the first harvest .... but then we harvest every 8th year 1800 m3 = GBP 234000,-

In addition, there is 1/3 branch mass, which can further be sold for the production of chips or insulation batts.


In addition, there is the sale of CO2 quotas, as cf. GCO calculations from the 7th growth year give 52 tonnes of CO2 per hectare per year, which in 2022 prices is calculated at GBP 52 per tonne. These prices will cf. EU increase to GBP86 per ton in 2030.

In comparison, winter wheat on the maximum lands per year yields up to 8.3 tonnes per hectare

Operating costs per hectare per year for winter wheat are approximately GBP 495 per hectare, while operating costs for paulownia are a maximum of GBP 141 per hectare.

The calculations for the above are based on the first 10-12 years of operation, while the yield for the following 8-year operations is proportionally higher per year.
