Nitrogen Contribution and Value of Chichpea and Fababean in Cereal-Production Systems

Plain text source: 
Nitrogen fixation activity of legumes is strongly linked to productivity and suppressed by soil nitrate... Data from the NSW Department of Primary Industries (DPI) long-term rotation experiments in northern NSW showed a positive effect of no-tillage on productivity and N2 fixation of both chickpea and fababean (Felton et al. 1998; Marcellos et al. 1998; Herridge et al. 1998)... Nitrate levels for Year 2 are after a 6-month summer fallow and for Year 3 are after an 18-month summer-winter-summer fallow (source: unpublished data of W. Felton, H. Marcellos, D. Herridge, G. Schwenke and M. Peoples)..
