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 plantremediator 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.

Peran Edu-Tainment Dalam Membangun Komitmen Dan Peran Nyata Pada Gerakan Jihad Kedaulatan Pangan

“…Pengelolaan siklus tertutup organik dan integrasi dalam suatu kawasan terpadu antara ICM, IFM, IPM, IMM, INM merupakan ciri utama dalam IBFS agar terjadi sistem daur tertutup yang mandiri dan berkualitas.Pengelolaan perlindungan bio terpadu dan pengelolaan ekosistem kesehatan, merupakan syarat mutlak agar konsep kembali alam dengan produktivitas serta kualitas hidup dan lingkungan yang lebih baik bisa terjamin dan berkelanjutan.Manajemen ekologi lanskap terpadu dan konsep agropolitan merupakan salah satu strategi penghilangan kotak-kotak egosentris dalam IBFS, sehingga tidak lagi mementingkan ego sector sendiri-sendiri, namun justru harus bersinergis.Dengan demikian pengelelolaan bahan organik harus dikelola dalam satu kesatuan lahan yang luas.Pengelolaan khusus tanaman perlu juga dilakukan karena masing-masing spesies tanaman mempunyai karakter hidup dan produktivitas sendiri-sendiri (Agus & Wulandari 2012).Selanjutnya, IBFS harus dikelola dalam suatu sistem holistik dan terintegrasi (Agus, 2006a(Agus, , b, 2010a(Agus, , b, 2012a.

Forest Land Change Assessment of Karang Mumus Sub-Watershed Area

“…The dynamics of using forest land to become agricultural land causes damage to the sub-watershed ecosystem, including an increase in the value of the average flow coefficient (C average), where the higher average C value causes the resulting in greater flood discharge (Agus & Wulandari, 2012;Endayani et al, 2019;Halim, 2014). Other effects include alteration of the watershed's hydrological state both locally and beyond, drought, erosion, and lower land production (outside the scene) (Halim, 2014;Pertiwi et al, 2011;Ping, 2012).…”

The earthworm’s diversity and their relationship to the soil physicochemical properties under the stands of perennial plant at the Mount Merapi forest, Yogyakarta, Indonesia

“…It was expected that the plants could prevent landslides and erosions (Idjuddin et al 2012) and also contribute to fertilize the soil underneath the plants (Yatso and Lilleskov 2016). It is expected that the leaf blossom of the plant will enrich the soil organic matter content so that the process of soil fertility recoveries will take place faster (Agus and Wulandari 2012).…”
