Use the Groasis capillary drills for planting projects
Cost calculations of using the Groasis capillary drill while planting Groasis Waterboxx® plant cocoons as an alternative to handmade planting holes.
Planting projects on a small scale can easily be done by hand. Once projects on a bigger scale are done, this becomes difficult. As an example, we take an imaginary project. The client wants to plant 600 weeks x 1 million trees (2 million hectares x 300 trees / 12 years)
That is 1 million planting holes per week.
Suppose each man makes 4 planting holes per hour, working in a high temperature, with rocks in the soil, then you need 250,000 man hours per week. That is 6,000 man to dig planting holes. Plus, the transport (120 buses), housing, food, organization and management. This is not easy to organize.
Info: in Morocco the government does some planting projects 500 km south of Oujda, deep in the desert. They calculate 2 planting holes per man per day. Maybe that is very low, but it is their experience. With 6,000 man and +45°C, 4 holes per hour is a definitely a challenge.
The cost price of tree planting holes made by hand
Suppose a man's wage is 3 US$ per hour. The cost of making a planting hole by hand if made 6 per hour - excluding the transport (120 buses), housing, food, organization and management - is 0,50 US$.
The cost price of tree planting holes made by the Groasis capillary drill
One drill with 3 drills (that's what we are developing) makes approximately 90 holes per hour. (each 2 minutes, 3 holes). That is in 84 hours – 7 days x 12 hours - total 7,500 holes
This means that the client needs 140 drills and tractors.
The tractor investment is 60K US$ 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.

Use the capillary drills to make planting holes
What is the conclusion of using the Groasis capillary drill compared to handmade planting holes?
- For bigger projects a capillary drill makes it easier to organize it.
- The cost price for the making of a planting hole with a capillary drill is considerable lower than making one by hand: 10 cents compared to 50 cents.
The present situation of the development of the Groasis capillary drill
The single drill is ready. One works in Dubai and the other in Spain. The functioning of the single drill can be watched in this YouTube video. Besides that, we have developed 5 other drills. You can find them all here.
What is the conclusion of using the Groasis Ecological Water Saving Technology for reforestation projects?
- Using the Groasis Ecological Water Saving Technology to do reforestation projects is far cheaper than using drip irrigation. You can compare the costs here;
- Drip irrigation uses scarce groundwater or water from reversed osmosis and is not sustainable;
- The Groasis Ecological Water Saving Technology doesn't use electricity for pumps;
- The Groasis Ecological Water Saving Technology uses water from air that is for free;
- The survival rate of trees while using the Groasis Ecological Water Saving Technology in dry areas is over 90%;
- The Groasis Ecological Water Saving Technology can be used in each climate zone and on each soil type, including rocks;
- The Groasis Ecological Water Saving Technology is a copy from how Mother Nature plants trees and bushes;
- The Groasis Ecological Water Saving Technology is simple and easy to implement;
- The Groasis Ecological Water Saving Technology is a very efficient method to upgrade the value of present wasteland to productive land with economical interesting trees on a sustainable way.
