It's not a secret that trees have increased their rate of growth in the last 40 years. It's always interesting to listen to a older RPF exclaim how the trees can be so tall when the trees that were harvested took so much longer to get to the same height. What's changed?
Freya Logging is only 10 years old. When we started this company atmospheric carbon was around 402ppm. The air we all breathe in this morning is now 427ppm.
There is an increasing body of science that shows that spruce trees are very active in the carbon market below ground. They trade with various ectomycorhyzal networks, a fancy way to say mushrooms. As they trade they get things like nitrogen, water and other good things in return.
Scientists have noticed a strong correlation between increasing carbon levels in the air and decreasing soil carbon levels in the A horizon-ie not the lfh layer. This appears to be related to spruce trees sending excess carbon to cortinaria (a mushroom that smells like metal and is common and poisonous) mushrooms that in bring soil up to the tree from the ground. This is leading to higher levels of forest growth.
One way to keep more carbon in the ground is add nitrogen to the soil which seems to keep the tree growing without depleting soil carbon. This explains one of the reasons why we fly around with urea (46-0-0) and sell carbon credits from that activity.
Thinning puts about 20 tonnes of branches/ hectare onto the ground. Branches are about 1 percent nitrogen by weight. So we could hypothesize that (20,000kg*.01=200) putting 200kg of nitrogen per hectare, in a natural, biodiversity enhancing application called woody debris, would also help trees not have to trade soil carbon for nitrogen from cortinaria networks, which would in turn make thinning an amazing way to store even more carbon in the soil while it's safe!
This all makes sense if we look at the world that poor starving humans created when we killed the last of the north America elephants, who would have put massive amounts of nitrogen into the system, thereby increasing the amount of carbon stored in the soil in forest ecosystems, which in turn explains why wild meat densities crashed from 10,000kg/km2 13,000 years ago to 40kg/km2 today. We can grow the pie of biodiversity if we put our minds to it.
