“…The content of soil organic matter (SOM) can also be used as an indicator of soil quality improvement. Setyawan et al, (2011) reported that in degraded soils (0-3 cm) of mine sites the content of SOC was relatively high, 52-130 g kg -1 after 7 years of rehabilitation, in which the soils underwent a relatively rapid recovery in tropics Kelian East Kalimantan with 3.500 mm year -1 rainfall. Hermansah et al, (2010) reported that the total SOC in the 0-10 cm soil layer in mixed garden, cinnamon plantation, and cacao plantation was 7.01%, 5.73% and 4.80% respectively, in which the high content of organic C of Inceptisols in these various land uses in Pauh, Padang was caused by the high input of organic materials coming from clearing grass and underbrush growing under the mature plants and then the derived biomass left in soil surface underwent decomposition.…”

Karbon (C) organik tanah yang merupakan bagian utama dari bahan organik tanah mengalami penurunan sebagai akibat perubahan-perubahan penggunaan lahan dari kondisi alami menjadi lahan-lahan pertanian. Penurunan C organik tanah menjadi semakin besar karena masukan bahan organik yang rendah dan bila penurunan ini. berlangsung terus menerus maka pada akhirnya menyebabkan degradasi tanah. Artikel ini membahas peranan, dekomposisi dan struktur dari bahan organik tanah dalam hubungannya dengan dinamika fraksi C organik tanah pada pengelolaan lahan yang berbeda di daerah tropis basah. Perubahan penggunaan dan pengelolaan lahan menyebabkan terjadinya perubahan C organik total dan fraksi-fraksi C organik labil dan stabil tanah. Beberapa penelitian telah menunjukkan bahwa fraksi C organik labil seperti C organik partikulat lebih responsif terhadap perubahan-perubahan dari pengelolaan tanah dan merupakan suatu indikator yang sensitif dari kualitas tanah. Disamping itu fraksi C organik stabil seperti asam humat yang mengalami perubahan karena praktek-praktek pengelolaan tanah dapat digunakan untuk menilai kapasitas potensial tanah sebagai penyimpan karbon. Perubahan-perubahan penggunaan lahan dan pengelolaan tanah mempunyai pengaruh negatif dan positif terhadap C organik total, fraksi C organik labil (C organik partikulat) dan fraksi C organik stabil (asam humat). Praktek-praktek pengelolaan yang dapat mempertahankan dan memperbaiki fraksi-fraksi C organik tanah meliputi sistem agroforestri, aplikasi pupuk organik, mulsa dan pengembalian sisa tanaman ke dalam tanah. Fraksi C organik partikulat dan asam humat menunjukkan perubahan-perubahan yang lebih besar dibandingkan C organik total akibat perubahan-perubahan penggunaan lahan dan praktek-praktek pengelolaan tanah di daerah tropis basah.Key words : Fraksi C organik, penggunaan lahan, tropis basah

“…Organic material consisting of litter and chunks of twigs and stems are spread as mulch because this material plays an important role in maintaining soil moisture around the roots and stems of plants. Moreover, organic matter affects the soil's ability to provide nitrogen (Nadalia and Pulunggono 2020) and is the main source of nutrients for plant growth (Noviyanto et al 2017;Turner et al 2015) after experiencing microbial decomposition (Setyawan et al 2011). Habitat conditions with various species will make suitable habitats for other organisms (Riefani et al 2019).…”

Abstract. Soendjoto MA, Riefani MK, Triwibowo D, Wahyudi F, Choirun D, Perdana YP. 2023. Spontaneously growing plants on revegetation sites of former coal mine in South Kalimantan Province, Indonesia. Biodiversitas 24: 1610-1620. Plants that grow and develop on the revegetation sites of post-coal mining are not only plant species that are intentionally planted, but also those that grow spontaneously. The aim of the research was to inventory plant species that grow spontaneously on revegetation sites of former coal mine sites in South Kalimantan Province and to analyze their presence mechanism and maintenance practices. Vegetation sampling was conducted on the plots established along the path with the size of each plot was 2 x 2 m2. All plants herbs (except grasses) and seedlings (shrubs, bushes, lianas and trees) within the plots were recorded and the vegetation composition was analyzed using Important Value Index as the parameter. Vegetation was monitored for 5 periods from 2018 to 2022 at the revegetation sites of two different planting years, i.e. 2016 and 2017. At Site-2016, 60 species belonging to 22 plant families were found and 71.67% of them grew spontaneously, while at Site-2017 there were 58 species belonging to 22 plant families and 70.69% of them were plants that grew spontaneously. Spontaneously growing species varied not only by location, but also by monitoring period. They are present at revegetation sites through seed dispersal mechanisms facilitated by natural activities (such as animals, wind, and water) as well as human activities. There are several management practices to facilitate vegetation succession, one of which is through spraying herbicides of weeds and invasive understorey species.

“…Growing CCs create a conducive environment for microbial growth and activities, and upon the decay of CCs, the fungi are attacking residues first followed by bacteria ( Hodge et al, 2001 ). CCs had a positive impact on soil microbial abundance, microbial activity, plant metabolism affecting soil respiration, and plant mineral nutrition ( Setyawan et al, 2011 ), depending on the weather, plant species, and the season of the year. Grasses as CCs played an important role in soil management in citrus orchards and showed that grass roots release stimulating compounds for arbuscular mycorrhizal fungi, which is beneficial for plant growth ( Lekberg and Koide, 2005 ).…”

Sustainable reduction of fertilization with technology acquisition for improving soil quality and realizing green food production is a major strategic demand for global agricultural production. Introducing legume (LCCs) and/or non-legume cover crops (NLCCs) during the fallow period before planting main crops such as wheat and corn increases surface coverage, retains soil moisture content, and absorbs excess mineral nutrients, thus reducing pollution. In addition, the cover crops (CCs) supplement the soil nutrients upon decomposition and have a green manure effect. Compared to the traditional bare land, the introduction of CCs systems has multiple ecological benefits, such as improving soil structure, promoting nutrient cycling, improving soil fertility and microbial activity, controlling soil erosion, and inhibiting weed growth, pests, and diseases. The residual decomposition process of cultivated crops after being pressed into the soil will directly change the soil carbon (C) and nitrogen (N) cycle and greenhouse gas emissions (GHGs), and thus affect the soil microbial activities. This key ecological process determines the realization of various ecological and environmental benefits of the cultivated system. Understanding the mechanism of these ecological environmental benefits provides a scientific basis for the restoration and promotion of cultivated crops in dry farming areas of the world. These findings provide an important contribution for understanding the mutual interrelationships and the research in this area, as well as increasing the use of CCs in the soil for better soil fertility, GHGs mitigation, and improving soil microbial community structure. This literature review studies the effects of crop biomass and quality on soil GHGs emissions, microbial biomass, and community structure of the crop cultivation system, aiming to clarify crop cultivation in theory.
