The Abundance of Pioneer Vegetation and Their Interaction with Endomycorrhiza at Different Land Qualities after Merapi Eruption
Abstract: Eruption of Merapi
volcano caused accumulation of lahar materials that led to extensive land
degradation. This research was to study
the population of pioneer plants and their correlation with endomycorrhiza
population at different land qualities
after Merapi eruption. Samples of soil,
pioneer plants, and endomycorrhiza were collected from Merapi volcano, 1 year
after eruption, using stratified sampling method based on plant densities, with
the following categories: dense vegetation, moderately dense vegetation, sparse
vegetation, and control (bare land), with 3 replications for each
category. Pioneer plants and
endomycorrhiza were identified. Plant biomass, soil pH, total-C,-N, and
exchangeable-K, -Ca, -Mg, -Fe were analyzed. The abundance of pioneer plants
and their interaction with mycorrhiza was strongly correlated with depth of
eruption material, quantity of sandy texture, soil pH, total-C and total-N,
exchangeable-K, exchangeable-Ca, exchangeable-Mg, and exchangeable-Fe. Among the 12 identified pioneer plants, only
Acacia villosa, Fiurena ciliaris, and Bidens pilosa were recommended as
plant-remediator to improve soil chemical, physical and biological properties.
Among the 3 genera of endomycorrhiza (Acaulospora, Gigaspora, Glomus), only
Acaulospora was recommended to be a biological agent to rehabilitate sandy soil
area. This research indicated that
adaptive pioneer plants and endomycorrhiza
were likely to be suitable for biological agents to stimulate recovery of
degraded land through improvement of physical, chemical, and biological
properties, that will stimulate plant growth and biodiversity.
