This study was conducted to develop the technique for cultivation of forage crops using swine slurry in fallow paddy land located in the mid-mountain area (FPL). The field experiments were carried out from 2007 to 2009 on FPL at Kumsan, Chungbuk province in Korea. Swine slurry was prepared which decayed for 6 months. The experimental plots were consisted of seven treatments; tall fescue-based mixed pasture applied with chemical fertilizer (Control), mono-tall fescue pasture (MTF), tall fescue-based mixed pasture (TFBM), mono-Perennial ryegrass (MPR), mono-Italian ryegrass (MIR), mono-Red clover (MRC and mono), Reed canarygrass (MRCG) applied with swine slurry. The field of tall fescue-based pasture had been sown with a grasses mixture containing ‘Fawn’ tall fescue, ‘potomac’ orchardgrass, ‘Reveille’ Perennial ryegrass, and ‘kenblue’ Kentuky bluegrass, ‘Kenland’ Red clover. Seeding rates were 16, 6, 4, 2 and 2 (kg) per ha, respectively. DM yields of forages and rates of grass coverage were higher in MTF, TFBM and MRCG as compared with control treatment. This result means that FPL has contained with favorable conditions for growing grass, because forage productivity is more than 14.5 tons per ha per year in fallow paddy land. In addition, the farmer can save the trouble of repeated plowing and sowing every year, with the introduction of perennial grasses. The farmer must conduct the re-seeding and induce the improvement of management methods for the elevation of the persistence of red clover and perennial ryegrass, because both red clover and perennial ryegrass having high nutritive value and palatability was less persistent. Therefore, we suggest that FPL may be the good land for forage production utilizing swine slurry and swine slurry can be applied on FPL without any negative effects on DM production and the property of soil. FPL of Korea can be better utilized by applying swine slurry to the mono and/or mixed swards.

윤세형(Sei Hyung Yoon),김종근(Jong Geun Kim),정의수(Eui Soo Jeong),임영철(Young Cheol Lim) 한국초지조사료학회 2008 한국초지조사료학회지 Vol.28 No.4

본 시험은 유기조사료 생산에 적합한 동ㆍ하계 사료작물을 선정하고, 이를 통한 지역별 유기조사료 생산을 위한 적정 작부체계를 선발하기 위하여 수행되었다. 관행재배 조건과 유기재배 조건에서의 사료작물별 생육특성의 차이는 하계사료작물에서 현저하게 나타났다. 즉 사료용 옥수수는 잡초 발생으로 생육이 억제되어 관행재배에 비해 현저한 수량감소를 나타낸 반면 수수×수단그라스 교잡종은 잡초 발생이 없어 관행 옥수수 대비 높은 수량을 나타내었다. 동계사료작물은 관행재배와 유기재배에 의한 차이는 크지 않았고, 호밀과 이탈리안 라이그라스 두 작물간 건물생산성 측면에서는 호밀이 약간 우세하였으나, 사료가치를 고려한 가소화영양소 총량에서는 이탈리안 라이그라스가 우수하였다. 그러나 그 차이는 크지 않아 남부지역에서는 호밀과 이탈리안 라이그라스 모두 유기조사료 생산에 적합한 동계사료작물로 판명되었다. 본 시험의 결과를 종합적으로 고려한 남부지역에서 유기조사료 생산을 위한 최적 작부체계는 수수×수단그라스 교잡종과 호밀 혹은 수수×수단그라스 교잡종과 이탈리안 라이그라스라 할 수 있다. This experiment was conducted to investigate the selection of regional double cropping system for production of organic forage in southern region of Korea. The species of forage crop used in this experiment were com, sorghum×sudangrass hybrid and japanese millet for summer crops and rye and Italian ryegrass for winter crops. In organic cultivation condition, sorghum×sudangrass hybrid showed higher DM(dry matter) and TDN(total digestible nutrient) yield than that of com. Dry matter yield of com which cultivated in organic condition decreased to about 35% that of control because of weed. In winter crops, DM and TDN yield of rye is similar to that of Italian ryegrass. We could not find out the difference of nutrient value between each treatments. It means that the amount of nutrient is affected by DM productivity of each crop. The result of this study indicated that sorghum×sudangrass hybrid (summer crop) and rye (winter crop), sorghum×sudangrass hybrid (summer crop) and Italian ryegrass (winter crop) cropping system could be recommended as producing high yield of organic forage in southern region of Korea.

초지에서의 돈분액비 시용수준에 관한 연구

윤세형(Sei Hyung Yoon),임영철(Young Chul Lim),김종근(Jong Geun Kim),정의수(Eui Soo Jeong) 한국초지조사료학회 2006 한국초지조사료학회지 Vol.26 No.2

This experiment was carried out to investigate the availability of swine slurry on mixed grassland pasture. Three types of fertilizer was used, chemical fertilization(N-P₂O?-K₂O=210-150-180 ㎏/㏊), no fertilization and swine slurry was further subdivide into three groups (100%, 150%, 200%) as compared to the level of N used in the chemical fertilizer. The results showed that dry mater yield of forage was increased with increasing application level of swine slurry. Production of dry matter of swine slurry 200% was similar to that of chemical fertilizer, but percentage of legume in mixed pasture was lower in chemical fertilization. Percentage of legume was increased with increasing application level of swine slurry. Level of NO₃-N in filtered water was very low in all groups applied with swine slurry. Based on this results the optimum level of swine slurry application is 200% of the normal standard of N fertilizer used in grassland pasture.

윤세형(Sei Hyung Yoon),지희정(Hee Chung Ji),이상훈(Sang-Hoon Lee),최은민(Eun-Min Choi),정민웅(Min Woong Jeong) 한국초지조사료학회 2010 한국초지조사료학회지 Vol.30 No.4

쌀 소비 감소로 인해 발생하는 중산간지 휴경답에서 노동력 절감을 위해 한번 파종으로 다년간 이용이 가능한 목초의 도입을 위해 본 시험을 수행하였다. 장소는 충남 금산이며 처리는 화학비료를 이용한 톨페스큐 위주 혼파조합(대조구)과 퇴비를 시용한 톨페스큐(Fawn) 단파구, 페레니얼 라이그라스(Reveille)단파구, 톨페스큐위주 혼파조합(톨페스큐 16, 오차드그라스 6, 페레니얼 라이그라스 4, 켄터키블루그라스 2, 화이트클로버 2(㎏/㏊)), 극만생 이탈리안 라이그라스(Ace), 레드클로버(Kenland)단파구 및 리드 카나리그라스(Venture)단파구를 두었다. 건물수량 및 영속성의 기준이 되는 목초율은 톨페스큐 단파구, 톨페스큐 위주 혼파구, 리드 카나리그라스가 우수하여 이 초종과 혼파조합이 중산간지 휴경답에서 퇴비를 이용하여 초지를 조성 이용할 경우 유리한 것으로 판명되었다. 또한 이 처리구의 ㏊당 연간 건물생산성은 15톤을 넘는 수준으로 중산간지 휴경답이 목초 재배에 매우 유리함을 입증하고 있다. 또한 다년생 목초의 도입으로 매년 반복되는 경운 파종하는 번거로움을 생략할 수 있는 유리함도 있다. 또한 사료가치와 기호성이 높은 레드클로버나 페레나얼 라이그라스는 영속성이 낮으나 보파 등 관리방법의 개선을 통해 이용이 가능할 수 있을 것이다. 극만생 품종으로 4-5년간 이용이 가능한 것으로 보고된 극만생 이탈리안 라이그라스는 국내에서 재배되는 이탈리안 라이그라스와 같은 경향을 보였다. 이는 다년생목초와 예취 및 비배관리를 동일하게 한 사실에 기인할 수도 있으므로 금후 이탈리안 라이그라스에 적합한 관리를 통해 재검토되어야할 필요가 있다. 이와 같이 중산간지 휴경답에 적합한 초종이나 혼파조합을 이용하면 생력적으로 사료가치와 기호성이 높은 양질 목초의 고위 생산성을 달성할 수 있음이 입증되었다. Recently, fallow paddy land located in the mid-mountain area (FPL) due to a decrease in rice consumption has increased in some regions of our country. So, grasses and forage crops available for years in once sowing should be introduced in FPL. This study was conducted to develop the technique for cultivation of grasses and forage crops using animal manure in FPL The field experiments were carried out from 2007 to 2009 on FPL at Kumsan, Chungbuk province in Korea. Cattle feedlot manure (CFM) was prepared by mixing feces and urine of cattle with rice straw in cattle feedlot for 6 months. The experimental plots were consisted of four treatments; tall fescue-based mixed pasture applied with chemical fertilizer (Control), mono-tall fescue pasture (MTFP), tall fescue-based mixed pasture (TFBMP), mono-Perennial ryegrass (MPR-FCM), mono-Italian ryegrass (MIR-FCM), mono-Red clover (MRC-FCM) and mono-Reed canarygrass (MRCG-FCM) applied with FCM. The field of tall fescue-based pasture had been sown with a grasses mixture containing 'Fawn' tall fescue, 'potomac' orchardgrass, 'Reveille' Perennial ryegrass, and 'kenblue' Kentuky bluegrass, 'Kenland' Red clover. Seeding rates were 16, 6, 4, 2 and 2㏊?¹, respectively. DM yields of forages and rates of grass coverage was higher in MTFP, TFBMP and MRCG-FCM as compated with control treatment. This result means that FPL has contained with favorable conditions for growing grass, because forage productivity is more than 15 tons per ha per year in fallow paddy land. In addition, the farmer can save the trouble of repeated plowing and sowing every year, due to the introduction of perennial grasses. The fanner must conduct the re-seeding and induce the improvement of management methods for the elevation of the persistence of red clover and perennial ryegrass, because both red clover and perennial ryegrass having high nutritive value and palatability was less persistent. Therefore, we suggest that FPL may be the good land for forage production utilizing FCM and FCM can be applied on FPL without any negative effects on DM production and the property of soil. FPL of Korea can be better utilized by applying FCM to the mono and/or mixed swards.

윤세형(Sei Hyung Yoon),김종근(Jong Geun Kim),정의수(Eui Soo Jeong),성시흥(Si Heung Sung) 한국초지조사료학회 2007 한국초지조사료학회지 Vol.27 No.4

본 시험은 유기조사료 생산에 적합한 동·하계 사료작물을 선정하고, 이를 통한 지역별 유기조사료 생산을 위한 적정 작부체계를 선발하기 위하여 수행되었다. 관행재배 조건과 유기재배 조건에서의 사료작물별 생육특성의 차이는 하계사료작물에서 현저하게 나타났다. 즉 사료용 옥수수는 잡초 발생으로 생육이 억제되어 관행재배에 비해 현저한 수량감소를 나타낸 반면 수수×수단그라스 교잡종은 잡초 발생이 없어 관행 옥수수 대비 높은 수량을 나타내었다. 동계사료작물은 관행재배와 유기재배에 의한 차이는 크지 않았으나, 생산성 측면에서 이탈리안 라이그라스 보다 호밀이 우수하였다. 따라서 작부체계에 영향을 미치는 요인이 하계 사료작물에서는 잡초의 발생여부, 동계사료작물에서는 사료작물의 종류에 기인됨이 밝혀졌다. 이를 종합적으로 고려한 중부지역에서 유기조사료 생산을 위한 최적 작부체계는 중부지역에서는 수수×수단그라스와 호밀이라 할 수 있다. This experiment was conducted to investigate the selection of regional double cropping system for production of organic forage in middle part of Korea. The species of forage crop used in this experiment were corn, sorghum × sudangrass hybrid and japanese millet for summer crops and rye and Italian ryegrass for winter crops. Sorghum × sudangrass hybrid showed higher DM (dry matter) and TDN (total digestible nutrient) yield than that of corn. Dry matter yield of corn decreased to 56% that of control because of weed. In winter crops, DM and TDN yield of rye is higher than that of Italian ryegrass. Rye was more adequate to produce organic forage in middle part of Korea. We could not find out the difference of nutrient value between each treatments. It means that the amount of nutrient is affected by DM productivity of each crop. The result of this study indicated that sorghum×sudangrass hybrid (summer crop) and rye (winter crop) cropping system could be recommended as producing high yield of organic forage in middle part of Korea.

본 연구는 제경법을 이용한 유기초지 조성기술을 확립하기 위하여 2005년부터 2007년까지 3년 동안 수행하였으며 방목축으로는 흑염소가 사용되었다. 시험설계는 관행조성구인 대조구, 퇴구비시용 후 방목구, 방목 후 퇴구비 시용구, 방목 후 퇴구비 시용 재방목구로 처리하였다. 목초정착률은 관행구인 대조구가 유기조성구에 비하여 현저하게 증가하였으며(p<0.05), 또한 건물생산성도 유기조성구에 비하여 대조구에서 현저한 증가를 나타냈다. 조성 후 연차가 경과함에 따라 식생 및 건물생산성이 개선되어 조성효과와 아울러 조성 후 관리의 중요성을 인식할 수 있다. 목초의 사료가치는 대조구와 유기조성구 모두 큰 차이는 나타나지 않았으며, 화본과 목초의 비율은 조성1년차가 2년차에 비하여 높은 경향을 보였다. 시험 종료 후 토양성분을 조사한 결과 pH와 양이온치환용량은 시험전과 거의 변화가 없었으나 유기물과 인산함량은 약간 증가하였다. This study was carried out to determine the effect of establishment of organic pasture by hoof cultivation with Korean black goat on productivity of grassland and properties of soil. This study was conducted from August, 2005 to September, 2008 at Cheonan, Korea. Experiment was designed composing with 4 treatment : Standard (Control, T1), Grazing after application of cattle manure (T2), Application of cattle manure after grazing (T3), Application of cattle manure at half of grazing (T4). The establishment ratio of pasture in control treatment increased significantly as compared with that of organic treatment (p<0.05). The yield of dry matter (DM) of pasture in control treatment increased significantly as compared with that of organic treatment. The contents of crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF) and dry matter digestibility (DMD) of pasture were not influenced by cattle manure and grazing method. Grasses coverage ratio in grassland in second year after grassland development were higher than that of first year. The contents of organic matter (OM) and P₂O? in soil samples collected in organic treatment at the end of the experiment were higher than those of control. However, The pH, and the concentrations of CEC (Ca, Na and Mg) in soil samples collected in organic treatment were hardly influenced, as compared with those at the beginning of the experiment. This study suggests that the grasses and legumes coverage ratio in grassland can be improved by suitable pasture management.
