“…기존에 국내에서는 토양개량제로서 녹비작물과 가축분뇨액비를 이용한 연구가 상당히 진행되었고, 토양내 탄소를 증가시키고 비옥도를 개선하여 건강한 토양환경을 유지할 수 있는 연구 결과들을 보여주었다 (Lee et al, 2014;Kang et al, 2020). 그러나 농촌노동력 감소와 동계작물 재배 기피 등의 현상은 경지이용률과 식량자급률을 점점 감소시키 고 있기 때문에 농업생산성을 증대시키기 위한 새로운 작부체계가 요구되었다.…”

This study was conducted to investigate corn growth and soil fertility after soil amendment application of three types in an upland field in South Korea. Each of the barley straw biochar (BSB, applied at 1,000 kg 10a -1 ), animal carcass biochar (ACB, applied at 1,000 kg 10a -1 ) along with compost (applied at 2,000 kg 10a -1 ), and bottom ash (BA, applied at 1,000 kg 10a -1 ); the Control area was only treated compost. The corn grain yield was improved when grown under BSB, ACB, and BA with compost. Overall, biochar application had more effect on the productivity of biomass and corn yield, and showed significant results in corn cultivation. In particular, the corn grain yield was the highest under BSB treatment was over 22%, 11%, and 7% higher than those grown under Control, ACB, and BA treatments, respectively. Soil chemical properties after soil amendment addition were improved. In particular, soil pH and CEC related to crop nutrient availability were significantly increased in BSB, ACB, and BA areas compared to those in Control area. Therefore, these results indicate that corn productivity, when cultivated in soil conditions such as those in an upland field in South Korea, can be increased by application of soil amendments including BSB, ACB, and BA with compost.

The purpose of this study was to evaluate the effects of liquid manure to increase the yield of green manure in winter season, and to investigate the effect of green manure incorporation to increase the yield of maize grain and nutrient balance improvement in upland soil. The green manure used in this experiment was barley and hairy vetch with a mixed ratio of barley and hairy vetch (75:25), respectively. Liquid manure applied 0, 26, 52, 78, and 104 Mg ha -1 , respectively, and the half of the total amount was applied as basal fertilizer, and the other half was topdressing. Nitrogen inputs through liquid manure were 0, 7.1, 15.6, 21.5 and 28.4 kg ha -1 , respectively, and the phosphorus inputs were 0, 11.3, 22.6, 33.9 and 45.2 kg ha -1 , respectively. The yield of green manure crops increased significantly with the increase of liquid manure application, but the yield of hairy vetch decreased. In the summer season, the green manure crops were incorporated, and the compost was used in the conventional treatment. The yield of maize grain increased with increasing green manure yield. The yield of maize grain of green manure crops incorporation treatments was up to 81% compared to conventional cultivation treatment, however the two-year experiments showed an increase on maize grain yields in green manure incorporation treatment. In addition, the incorporation of green manure crops greatly improved the phosphorus balance in compared to conventional cultivation. Therefore, productivity improvement of green manure crops by utilizing liquid manure is thought to have significantly contributed to the improvement of maize grain yield and nutrient balance.
