제안 방법
- Soil available phosphate was determined according to the method of Lancaster. For determination of soil exchangeable cations (K, Ca, and Mg), air-dried soil samples were extracted with 1 N ammonium acetate for 30 minutes, and concentration of the extract was determined by AAS (Analyst 400, Perkin Elmer, USA).
- Chemical analysis for determination of the mineral content of each sample was conducted according to methods of soil chemical analysis (NIAST, 1988). For the determination of soil pH, air-dried soil samples were mixed with deionized water with a ratio of 1 : 5 (soil : water) and the pH of the clear supernatant was measured by pH electrode (Orion VERSA STAR, Thermo fisher scientific, US), and then, soil electric conductivity (EC) was measured by electric conductivity meter (CM-30R, DKK-TOA, Japan). Soil NO3-N content was measured by Kjeldahl apparatus (K-314, BUCHI, Switzerland), after extracting from fresh soil sample with 2 M KCl for 30 minutes.
- The analysis of anthocyanins in grape skins was carried out using a HPLC system (Waters Alliance 2695, USA) equipped with a ACQUITY UPLC BEH C18 reverse phase column (2.1 × 50 mm).
- (20 m × 10 m) and all experiments were conducted by a randomized complete block design with three replications. The experiments were treated with hairy vetch (Vicia villosa), rye (Secale cereale), mixture of hairy vetch and rye, and natural grass as control. Hairy vetch and rye were fall-seeded at rate of 90 kg and 200 kg ha-1, a mixture of hairy vetch and rye were drilled at the rate of 45 kg ha-1 and 100 kg ha-1, respectively.
- The size of each experimental plot was 200 m2 (20 m × 10 m) and all experiments were conducted by a randomized complete block design with three replications.
대상 데이터
- The experimental fields were located at 36°19ʹ40ʺ N latitude and 127°56ʹ51ʺE longitude.
- This study was conducted on the organic farm field at sangju, Gyeongsangbuk-do, Korea, from October 2012 through September 2013. The experimental fields were located at 36°19ʹ40ʺ N latitude and 127°56ʹ51ʺE longitude.
데이터처리
- The results of each parameter in all three applications were subjected to analysis of variance, and treatment means were compared by Duncan’s multiple range test (DMRT) at the 5% probability level.
