“…또한 시설토양은 강우에 의한 치환성 양이온의 용탈이 발생하지 않아 더더욱 양이온의 축 적이 이루어지기 쉽다 (Behera and Shukla, 2014). 그러므로 심각한 염류집적과 양분 불균형을 해결하기 위해서는 거 듭된 토양검정과 결과에 기초한 적정시비를 유지하여야 한다 (Cho et al, 2018). 고도의 정의 상관을 나타냈다.…”

The chemical properties of greenhouse soils in Ganghwa were investigated every year from 2014 to 2018 in order to manage soil fertility and increase crop yield. In 2018, the average concentrations of chemical properties from greenhouse soils were analyzed: 6.4 for pH, 6.72 dS m -1 for EC (electrical conductivity), 23 g kg -1 for OM (amount of organic matter), 187 mg kg -1 for P 2 O 5 (available phosphate), 1.89, 12.09, 4.84 cmol c kg -1 for exchangeable potassium (K), calcium (Ca), magnesium (Mg), respectively. There were no significant changes in the contents of pH and OM from 2014 to 2018. However, the concentration of EC was 3.7 times higher than that of the proper standard recommended by Rural Development Administration in 2018. Further, the excessive frequency ratio about exchangeable cations were 60.6% for K, 93.9% for Ca and 95.9% for Mg based on the recommendation and the contents of exchangeable cations had a tendency to increase according to the years. The frequency ratio of P 2 O 5 which is insufficient in comparison with the standard was 83.8% and the concentration of P 2 O 5 was 1.9 times lower than that of the recommendation in 2018. The P 2 O 5 content had tended to decrease with years. The OM values of cucumber and tomato were higher than those of pepper and water melon, whereas the contents of P 2 O 5 were also insufficient in all crops. Based on principal component analysis, EC was significantly correlated with exchangeable cations, K, Ca and Mg from greenhouse soils in Ganghwa. In order to promote soil fertility of greenhouse in Ganghwa, it is necessary to apply phosphate fertilizer and manage soil nutrients based on the soil tests and analyses.

This study was performed to evaluate the chemical properties and soil quality of strawberry, watermelon, and tomato-grown soils in the intensive plastic film houses. Soil testing data (43,288), uploaded on Korean soil information system (http://soil.rda.go.kr) from 2010 to 2019, were analyzed. The study showed that the average values of pH and organic matter (OM) have been maintained under the optimum ranges, whereas electrical conductivity (EC), available phosphate (Avail. P2O5) and exchangeable (Exch.) cations (K, Ca, and Mg) were increased by 1.2 times in strawberry, and 1.3 times in watermelon and tomato. In addition, the soil chemical quality was the lowest in tomato and followed by watermelon and strawberry. Especially, a chemical quality of tomato-grown soils revealed the most rapid decrease until 2019. In order to improve soil environment for strawberry, watermelon, and tomato cultivation under the plastic film houses, a comprehensive soil management technique such as application of rice straw, chelating agent and microbal material, deep tillage, cultivation of hyperaccumulator for salts should be used to reduce the accumulated nutrients, and considering the results of the soil testing, adequate amount of fertilizer, compost, and soil amendment should be supplied to ensure stable crop productivity.

“…따라서 양분 손실을 최소화하면서 작물의 수량과 품질을 향상시키기 위해서는 수단그라스 재배지의 토 양 및 식물 영양 특성을 파악하고 두 특성 간에 미치는 영향에 대한 분석을 통해 생산성을 평가하고 적정 비료량을 설 정하는 것이 중요하다. 복숭아, 인삼, 딸기, 키위, 구지뽕나무 등의 작물은 토양화학성과 식물체 잎의 양분함량과의 관 계를 바탕으로 적정 비료 기준을 제시한 바 있다 (Seo et al, 2002;Jin et al, 2009;Choi et al, 2010;Kim et al, 2022;Song et al, 2022). 따라서, 본 연구에서는 수단그라스 재배농가의 수량에 따른 질소비료사용량, 토양화학성, 식물체 질소함량, 질소이용효율 등을 분석하여, 생산성에 대한 환경 또는 재배요인의 영향을 평가하고자 수행하였다.…”
