Effects of Maturation Periods of Pig Manure Composts on Growth of Leaf lettuce(Lactuca safiva L.)
돈분발효퇴비의 부숙기간이 상추 생육에 미치는 영향
Abstract
To clarify the proper and safe duration of maturation periods for sawdust-pig manure composts, leaf lettuces were applied with pig manure composts fermented for 15, 30, 45, 60, 75 days and 1 year (control) and cultivated in a plastic house with or without additional PE film tunnel. The changes in physiochemical properties of soil and leaf lettuce growth were measured. Shorter duration of maturation periods enhanced the generation of N
