“…Forest conversion into other land-uses (i.e., agroforestry, shrub, and crop) within Kalikungkuk micro watershed decreased 43-66% of total N in the top 10 cm depth of soil, as well as decreased 10-59 % of total N in the depth of 10-100 cm. Similarly, Kurniawan et al (2019) reported that changes of the forest into agroforestry systems (i.e., pine with crop, mahogany with coffee, and mahogany with taro) in volcanic soils decreased total N concentration at 0-10 cm depth of soil. The high concentration of total N in forest land was caused by the high input of organic matter such as leaf and stem litter which contributed 7-19% of the total N in the soil.…”

Degradation of soil functions in storing and cycling nutrients may be related to topography and land-use change. The research aimed to analyze the impact of land-use changes and slope positions on soil function in nutrient stock within Kalikungkuk micro watershed of East Java, Indonesia. Four different land-uses such as vegetable crops, agroforestry, shrub and forest were selected with three slope positions (e.g. ridge, slope, and valley), and three replications of each. Soil samples were collected at 0-10, 10-30, 30-50, and 50-100 cm depth of soil. Variables measured included soil properties (e.g. bulk density, soil texture, pH, CEC, soil nutrients). Slope positions impact on differences in soil physical (i.e. soil bulk density, soil texture) and chemical (i.e. total N, exchangeable K) properties. In addition, forest conversion to other land-uses (i.e. agroforestry, shrub, vegetable crops) decreased soil nutrient concentration (i.e. total C, total N, Ca, Mg, Na), and consequently resulted in degradation of soil nutrient stocks of especially C and N. The strong positive correlation between soil nutrient stock (e.g. C and N) and vegetation cover such as canopy cover, basal area, and litter (r = 0.63 – 0.78, r table 1% = 0.39) showed the benefit of biodiversity in maintaining soil function on the nutrient stock.

“…According to Agustian and Simanjuntak (2018), the soil organic matter content in the research plots was classified as high (3-5%) (PM) to very high (>5%) (NM, PFM and SPM) both at the depths of 0-0.2 m (Figure 3A) and 0.2-0.4 m (Figure 3B). It is known that the type of soil at the study site is classified as Andisols soil (Kurniawan et al 2019) and its formation is classified as a volcanic landform (Kurniawan et al 2019). Soil formation at the research site was influenced by the activity of Mount Arjuno from the parent material of volcanic tuff and ash which caused the high content of soil organic matter (Kurniawan et al 2019).…”

Abstract. Sudharta KA, Hakim AL, Fadhilah MA, Fadzil MN, Prayogo C, Kusuma Z, Suprayogo D. 2022. Soil organic matter and nitrogen in varying management types of coffee-pine agroforestry systems and their effect on coffee bean yield. Biodiversitas 23: 5884-5891. Coffee cultivation in agroforestry systems is mostly planted without soil fertility management. While there are several management interventions to improve soil quality in agricultural practices, it is not clear whether particular treatments, such as adding organic fertilizers and nitrogen fertilizers could increase coffee production in agroforestry settings. This study aimed to analyze soil organic matter and nitrogen in varying management types and its effect on coffee bean yield in a coffee-pine agroforestry setting in East Java, Indonesia. We evaluated four types of coffee management (treatments) namely: (i) no management, (ii) pruning coffee plant branches, (iii) a combination of pruning and addition of fertilizers with a planting distance of pine trees of 3 x 2 m, and (iv) pruning under pine trees with a planting distance of 6 x 2 m. The soil organic matter, total and available soil nitrogen were measured at 0-0.2 m and 0.2-0.4 m soil depths. We measured coffee bean yield to 100 coffee plants per plot. The coffee bean yield in the no-management treatment reached 376 kg ha-1, while the yield under the other three treatments increased up to 3.9 times compared with no-management. This increasing coffee bean yield did not correlate with soil organic matter in topsoil, with a correlation between coffee bean yield and total ant available soil nitrogen being positive and negative, respectively. We concluded that the limitation of N in the coffee-pine agroforestry system would require management intervention in the form of adding nitrogen fertilizers to increase coffee bean yield.

Soil environment, both biotic (e.g., microbial community) and abiotic (e.g., nutrients and water availability) factors determine soil fertility and health and are directly affected by soil management systems. However, only limited studies evaluate the combined effect of nutrients availability and soil disturbance on the soil bacteria community structure, especially in conventional agricultural practices, on the forests converted to agricultural land. This study aimed to provide a viewpoint of the effect of different soil management systems, i.e., forest soil (natural process) and tilled land, on soil bacteria community structure on forest converted to agricultural land, according to a metagenomics approach. Moreover, each land use was sampled to identify the bacterial community using 16S gene as a biomarker. The sequencing was performed using MinION (Oxford Nanopore Technologies) to read the DNA sequence from each soil sample. Principle Component Analysis (PCA) was performed to comprehend the relationship between availability of nutrients and bacterial diversity. The results revealed that the concentrations of soil micronutrients, such as iron, zinc, and magnesium, were significantly higher in forest soil than in tilled land. According to diversity indices, soil bacteria were more diverse in forest soil than in tilled land. Forest soil had more distinctive taxa than tilled land. Several species comprised the most abundant taxa, such as Candidatus Koribacter versatilis, Candidatus Solibacter usiatus, Rhodoplanes sp., Luteitalea pratensis, and Betaproteobacteria bacterium, were more scarce in tilled land. On the distinctive taxa in each soil sample, Anseongella ginsenosidimutans and Janthinobacterium sp. were the most abundant species in forest and tilled land, respectively. According to PCA analysis, soil management system affected the soil micro-and macronutrients also microbial community structure between forest and tilled land. In conclusion, soil management influences the essential nutrient content and bacterial community structure of soil. Better management should be adopted to maintain soil quality near forest soil.
