The lumber reached Equilibrium Moisture Content (EMC) probably within 1-2 years of being sawn. It’s probably around 12-15% moisture content. It will need to be 6-8% if it is a hardwood specie, or around 9-10% for most softwood species. You can get a cheap mosture meter to test it with. Here in the US they start at around $30.00.

There are many methods for approaching this. No matter the method, the wood must be stacked in a manner that allows good air flow in and around each and every board. This involved stacking it on stickers. Stickers are typically ~1” (~25mm) square wood sticks placed across the each layer of boards every 1/2 meter or so.

One traditional method was to stack it in the attic (during summer months) for 2-3 months. During the winter the wood would be stacked in the same room as the wood stove (heater) for several months.

One modern do-it-yourself method is to build a cheap poly film tent around the stack and place a dehumidifier and a small heat source and fan inside of it. There are a number of things that must be taken into account in executing this method. But it’s not rocket science.
