I have 10 acres - how many cars can I run ? (Hektar=cca 2 Akri)
The yield will vay. Weather is always a variable and can be a concern. By practicing the proven methods you can expect to achieve the EU average for Spring rapeseed (3.5 T/Ha) or Winter Rapeseed (5 T/hA).
Every 3 Tonnes of clean, dry seed will yield about 1000 litres of finished PPO. An average vehicle will drive about 15,000 miles !!!!!!!, a year and use about 1,500 litres of PPO or diesel.
So to answer the question 10 acres may yeild about 13-15 tonnes rapeseed which will make about about 3,500 to 5,000 litres of PPO. That should be enough PPO for 35,000 to 50,000 miles of motoring in vehicles.
