“…The research initiative lead by the Central Soil Salinity Research Institute in Karnal, India (Grewal and Abrol, 1986;Singh et al, 1988;Singh et al, 1989a, b;Singh, 1995;Bhojvaid et al, 1996) have been world leaders in using combinations of trees and grasses to reclaim these high pH soils. Prosopis juliflora was able to grow satisfactorily without amendments up to pH 9.0, but these authors found that when the soil pH was 10.4 it was necessary to plant the trees in auger holes with amendments of 3 kg gypsum and 8 kg of farmyard manure per hole (Singh, 1996).…”
