More efficient energy cultivation is achieved in part by growing at a higher humidity in a uniform environment. It has been a question of practice, but also within the research community it is a question: What is the minimum transpiration needed for a thriving and healthy crop. In the project: “Transpiration; balance between necessity and excess” we first carried out an inventory of available knowledge.
In the project: “Transpiration; balance between necessity and excess” we first carried out an inventory of available knowledge. The next step in this project is an analysis of practical situations and conditions in ongoing or completed research projects in which transpiration is measured accurately. It is important that there is a careful observation of the transpiration in the night available.
The first results of these analyses shows that the transpiration can be quite low, without deficiency symptoms occur. But if a problem arises, then a short period of time, a few hours, with a wrong water balance for the crop is already sufficient to get damage.
The outcome of the research should be to define well the risk situations and provide growers with practical guidelines for the control of humidity in energy efficient cultivation methods.
