Última Adsorption, immobilization and activity of cellulase in soil: the impacts of maize straw and its humification BABT Sinegani,Ali Akbar Safari; Sinegani,Mahboobe Safari. The present work aimed to study some aspects of sorption and immobilization of cellulase molecules on soil components by the analysis of the reactions of cellulase in a soil treated with different levels of maize residue and incubated for 90 days. The analysis of variance showed that the effects of the treatments of maize straw, incubation time and their interaction on cellulase adsorption, desorption and immobilization were statistically significant. The adsorption and immobilization capacities of soil by application of maize straw increased significantly. However they decreased with decreasing the soil organic matter (SOM) after 45 days of incubation. The desorption of adsorbed cellulase molecules from the soil by washing with distilled water depended on...

Ano: 2013 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-89132013000600001 EFFECT OF NITROGEN FERTILIZER AND MAIZE STRAW INCORPORATION ON NH4+15N AND N0(3) -15N ACCUMULATION IN BLACK SOIL OF NORTHEAST CHINA AMONG THREE CONSECUTIVE CROPPING CYCLES J. Soil Sci. Plant Nutr. Lu,Caiyan; Ma,Jian; Chen,Xin; Zhang,Xudong; Shi,Yi; Huang,Bin. A pot experiment was conducted to evaluate the effect of nitrogen (N) fertilizer and maize straw incorporation on the accumulation of NH4+-15N and N0(3)--15N in soil inorganic N pool among three consecutive cropping cycles, aimed to search for an effective N management practice to decrease superfluous accumulation of soil inorganic N and fertilizer N losses. The results showed that the amounts of soil NH4+-15N, N0(3)-15N and inorganic 15N, and their percent to applied 15N-labeled fertilizer declined significantly with sampling time (p ≤ 0.001).Compared to low N application rate (44.64 mg N kg-1 soil), high N application rate (89.28 mg N kg-1 soil) enhanced significantly the amounts of soil NH4+-15N, N0(3)--15N and inorganic 15N by 238.6%, 132.9%...
