In this study the kinetics of zinc release from <em>Fucus serratus<\/em> seaweed was investigated in a packed soil column leaching experiment over 1,776 h. The release of zinc from control (soil only) and treatment (soil + seaweed; equivalent zinc application rate of 1.42 kg ha<sup>\u22121<\/sup>) columns, measured by ICP-MS, demonstrated two distinct release stages. The cumulative zinc release data for each phase were fitted to five kinetic models: zero order, first order, Elovich, power function and parabolic diffusion. In the first stage (0\u2013400 hours) the release of zinc from both control and treatment was best described by a parabolic rate law, indicating release of zinc from a soluble soil reservoir. In the second stage\u00a0(400\u20131,776 h) zinc release followed a zero order rate law indicative of slow release from\u00a0an essentially insoluble reservoir. The modelled difference between the amount of zinc released from treatment and control columns in stage 1 (230 \u00b1 11 \u00b5g) represented the total amount of\u00a0zinc\u00a0added <em>via<\/em> seaweed. The parabolic rate constant for seaweed zinc release was 12.09\u00a0\u00b5g g<sup>\u22121<\/sup> h<sup>\u22120.5<\/sup>. In summary, the addition of <em>F. serratus<\/em> to soil is a viable source of labile zinc and a low cost agronomic option for mitigating zinc deficiency in soils.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>D.
