Dissipation of 14C from the soil-plant system was fairly rapid and after 9 weeks (during growth of cotton), ca 50 percent of the applied 14C was unaccounted. Subsequent losses were slower and during the remaining study period of 29 weeks, a further decrease of only 10 percent of the applied 14C occurred. Wheat growth and organic amendment caused a decrease in the loss of 14C from the soil-plant system. At all sampling intervals, a greater proportion of 14C was restricted to the top 0-10 cm layer and the amount consistently decreased with depth. In general, >80 percent of the 14C determined in soil at different sampling intervals was present in forms non-extractable with methanol.
