| Abstract: | This study presents development of a farmer’s
agroforestry model involving tree species that bioremediate water table
through efficient biodrainage (evapotranspiration). An
abandoned waterlogged (water table up to 2 m) degraded farm area (900 m x 200
m) adjacent to Balsamand canal at CCS HAU farm at Hisar, India was planted with
10 tree species (Callistemon lanceolatus, Eucalyptus tereticornis clone-3,
E. tereticornis clone-10, E. tereticornis clone-130, Eucalyptus
hybrid clone (E. tereticornis x E. camaldulensis), Melia
azedarach, Pongamia pinnata, Prosopis juliflora, Tamarix
aphylla, and Terminalia arjuna). Some trees showed excellent
survival and establishment over past 6 years. Further, a ‘cone of depression’
of water table immediately beneath each strip plantation was also noted as
compared with no depression in the control. Depression was to the maximum
magnitude beneath strips of Eucalyptus species (80-97 mm), Prosopis
juliflora (82 mm) and Tamarix aphylla (79 mm). An overall 20 cm decline
in water table was observed on entire site over this period making it arable.
It is opined that prudent strip plantation of trees on this model of agroforestry
system raised on farmer’s field bunds lowers saline water table remediating
degraded arable land and proved a low cost, high returns, socially acceptable
and environmentally friendly. It has been implemented on 4900 ha
waterlogged areas of Haryana, and could be planted
elsewhere with similar agro-climatic conditions. |
