Effect of organic manure on fulvic acid and humic acid of combined humus forms in wind blown soil

Three years experiments were conducted to study the effects of organic matter application on Fulvic acid and humic acid of combined humus forms in wind blown soil.The results indicated that different organic matter could improve the contents of fulvic acid in loosely combined humus and stably combined humus,and the contents of humic acid were no obvious difference among all the treatments,but the ratio of humic acid to loosely combined humus and stably combined humus were declined by compared with the treatment of CK.the same as the ratio of humic acid to fulvic acid in loosely combined and stably combined.It concluded that the effect of straw+muck+peat was the more effective than that of the other treatments.$$$$
