Put a table on top on the soil in order to find the evaporation of water during the night
This is the water quantity that attached to the table when I turned it in the morning
The roller scraper can be used as a weed controller and more important as a way to keep the capillary water in the soil
Under the roller that is made of vertical cutting blades that cut into the soil there is a horizontal cutting blade to cut the weeds
One walks with the roller scraper and easily you destroy all the weeds and create a loose layer of soil on top
As this layer is dry weed seeds cannot germinate in it so the soil keeps clean without any weeds
Under the loose soil the capillary water is locked up and cannot evaporate this gives a high efficiency of the available water
Detail of the humid protected soil in cooperation with the box vegetables can be grown with over 90% less water
The hard rocks lie in a loose layer on top of the soil to prevent the evaporation
