Abstract A field study was initiated in July 1984 in the Karnal district of Haryana, India to examine the forage production, mineral composition, nutrient cycling and reclaiming effects of Karnal grass (Leptochloa fusca (L) Kunth) grown in association with mesquite (Prosopis juliflora (SW) DC) in an agroforestry system on an extremely alkaline soil (pH 10.4, exchangeable sodium percentage 90). Karnal grass inter-crop gave 47 t ha-1 green forage in 15 cuttings without any amendment in a growth-period of about 50 months, proving its potential as a primary colonizer of abandoned alkali lands. The inorganic chemical composition of the grass, including trace elements Fe, Mn, Zn and Cu, indicated that the grass may be valuable fodder under these adverse edaphic conditions. Removal of 453 kg ha-1 of N, P, K, Ca, Mg, S, Fe, Mn, Zn and Cu in the crop in a 2-year growth-period did not result in any site depletion in available nutrients. Growing of Karnal grass with mesquite for a period of 52 months reduced pH and EC and improved organic C, available N and water intake capacity of a barren alkali soil. Further, the soil was improved to the extent that some moderately salt-tolerant crops such as Trifolium resupinatum, T. alexandrinum and Melilotus denticulata have been grown successfully after ploughing-under of Karnal grass. This study suggested that the biological approach for utilization and improvement of abandoned alkali soils is feasible. Under certain specific situations where the amendments either are not available or are costly, this approach may, indeed, be the only economic method of utilization of these marginal land resources.
