According to Song et al . ( ２００６ ) , the application ofunfermented liquid swine manure( ULSM ; high DM ％ ) to winter crop increased dry matter yield more than that of fermentedliquid swine manure ( FLSM ; low DM ％ ) , although there was no difference in soil quality between two DM concentrations .One time application of too much animal manure resulted in unbalanced soil base , salt contamination , and soil nutrient loss( Bracker , １９８２) . Studies were carried out to evaluate the effect of fermentation and split application of liquid swine manurefertilizer on the dry matter yield of Italian ryegrass and subsequent soil quality .Material and methods Experiments were conducted in a forage crop field in Jeju Livestock Institute for Promotion , fromNovember ２００５ to May ２００６ , using split plot design . The main‐plots consisted of two kinds of liquid swine manure fertilizersuch as the unfermented LSM and the fermented LSM , while the sub‐plots were composed of two times fertilizer applicationsuch as １００％ basal fertilizer( BF) and the ５０％ BF and ５０％ top dressing ( SA) .Table 1 Dry matter y ield andcrude p rotein content as a f f ectedby ap p lication o f liquid sw inemanure .TRT DMY Crude proteinkg / ha Content( ％ )FermentedBF 倡 ２ ,５３８ �１０ 镲.１SA倡倡 ２ ,５８３ �１０ 镲.４Mean ２ ,５６１ �１０ 镲.３UnfermentedBF ９ ,６６２ �９ 刎.６SA ７ ,９１４ �１０ 镲.６Mean ８ ,７８８ �１０ 镲.１Main ０ 趑.０１０ ０ *.７７０Sub . ０ 趑.２６３ ０ *.２９２M × S ０ 趑.２４２ ０ *.６２８BF倡 : basal fertilizer ,SA倡倡 : split applicationTable 2 Soil characteristics as af f ected by ap p lication o f liquid sw ine manure in thepasture p lot .TRT OM TN Ava .

A similar result was obtained by Song et al .( ２００６ ) . It is likely due tohigher total nitrogen and total phosphorus contents of ULSM than in FLSH . The total N content of the soil in the field treatedwith FLSM ( Table ２ ) was significantly higher than that with ULSM treatment ( p ＜ ０ .０１ ) . The split application of LSMsignificantly increased the soil OM contents , higher than with １００％ BF application( p ＜ ０ .０５) .Conclusions The application of unfermented swine liquid manure with a high DM content resulted in significant increases inItalian ryegrass DM yield , but the total N content of soil was lowered in the field applied with unfermented swine liquid manurethan in the field applied with fermented swine liquid manure with a low DM content . The split application of liquid swinemanure increased the soil OM contents , higher than with １００％ basal fertilizer application .ReferencesSong , Sang Taek , Moon Chul Kim and Kyoung Jun Hwang .
