The Effects of Fern (Gleichenia linearis) Mulching on Soil Properties, Humus Substance and Microbial Fauna in Soils Growing Tea in Phu Tho Province, Vietnam

Nguyen Xuan Cu | Tran Thi Tuyet Thu

Abstract: In Vietnam, Fern (Gleichenia linearis) is one of mulch materials for tea cultivation brings positive benefits such as moisturizing, protecting the soil from erosion and improving crop yield. Because of the high composition of total polysaccharide and C/N ratio, Fern residues have high persistent and should slowly decay is especially important to contribute to maintain organic matter in soil. A study was conducted on a typical Acrisol growing tea in Phu Tho province (Vietnam) to evaluate the effects of Fern mulch on soil properties, especially soil organic matter accumulation. The findings of this study suggest that Fern mulch application had positive effects on soil properties, particularly on soil humus and soil moisture. In general, soil moisture, soil bulk density, humus content and quality of soil is improved, and the activities of soil microorganisms is also enhanced. The effects of Fern mulch on soil properties depends on the rate of Fern application and timing. In this research, the rate of 25 tons of Fern/ha is considered more appropriate
