The cost price of tree planting holes made by the Groasis capillary drill
One drill with 3 drills (that's what we are developing) makes approximately 90 holes per hour (each 2 minutes 3 holes). That is in 84 hours – 7 days x 12 hours - total 7,500 holes. This means that the client needs 140 drills and tractors. The tractor investment is 60K US$ and the drill 50K US$. Suppose 1 combination makes holes during 6 years, that is 375,000 x 6 = app. 2 million holes. That is 5,5 cents per hole. We estimate 1 cent per hole for the transport (3 buses), housing, food, organization and management costs and 0,5 cents energy. Cost per planting hole 7 cents.
There are 140 tractor drivers, easier to organize than 6,000 people making holes by hand. They cost 250 dollar per week incl. housing etc.. That is 3 cents per hole.
The cost of making a planting hole by machine - including the transport (3 buses), housing, food, organization and management - is 10 cents.
