  • Water consumption of eucalyptus forestry plantations

    2009 - 11.16

    A forestry investment body in Minas Gerais,  a region of Brazil,  has recently conducted a series of studies into the consumption of water in eucalyptus plantations.

    The data showed that, from  an annual precipitation rate of 1299.0 mm,   57.1% (741.0 mm) was taken up by eucalyptus trees in the process of transpiration (which is the transfer of water from soil to atmosphere from absorption by plant roots and rhizomes), 9.8% of the total rainfall (128, 0 mm) was evaporated (evaporation is the direct transfer of water from the surface of plants and soil to the atmosphere). Between 0.5 to 1.3% (16.9 mm) were taken directly from the soil surface and 31.8% (414.0 mm) infiltrated the soil and replenish the water course.

    The conclusions drawn were that transpiration of 741.0 mm per year or 2.3 mm per day is similar to other forest species and perennial crop species and therefore,  the information generated suggests that groves of eucalyptus trees do not consume excessive quantities of water.

    The total of  evapo-transpiration (the sum of transpiration through evaporation), was 869.0 mm or 2.38 mm per day.  Because there was a surplus of 414.0 mm per year (31.8% of the rain event) the eucalyptus does not dry the soil).  This surplus is not used by plants during the year and was used to replenish the stream.  Furthermore, the maximum variation observed in the flow of the stream was 8.0% during the study period, indicating that the replenishment system of the stream was well regulated.

      Don’t you have free access for eucalyptus water consumption for studies? (Iam a student in Life Sciences for further studies)
