“…The exchangeable K content at both 0-20 cm and 21-40 cm depth was significantly affected by land use, slope, and their interaction with p < 0.05 (Table 5). Fitria et al (2021) also reported that land use systems and slope positions affected soil exchangeable K content within 0-100 cm soil depth. The exchangeable K content on 8-15% slopes is significantly higher than on 16-40% slopes.…”

Changes in natural land use for monoculture cropping systems may affect the soil properties over a certain period of time. In an attempt to evaluate soil chemical properties in the cassava cropping system, the research was conducted in Pati Regency, Central Java. Four land use systems were compared, i.e. monoculture cassava (cultivated for 5, 10, and 15 years) and agroforestry systems in two different slopes (i.e., 8-15% and 16-40%), with four replications. Soil samples from each location were taken at a depth of 0-20 and 21-40 cm for soil chemical analysis (pH, cation exchange capacity, organic C, total N, available P, exchangeable K, Ca, and Mg). Soils in agroforestry systems had higher pH, CEC, the content of organic C, total N, exchangeable K, Ca and Mg than in cassava cropping systems, especially on the slope of 8-15%. The soil under 15 years cassava and on the slope of 16-40% had the most degraded soil chemical properties, as reflected by the lowest content of organic C, total N, exchangeable K, and slightly lower CEC and the content of exchangeable Ca and Mg. Soil chemical properties on the slopes of 8-15% were significantly better than on the slopes of 16-40%, especially in CEC and the content of organic C, total N, exchangeable K and Mg. However, there was an unclear pattern of the available P content, which was possibly due to the application of P fertilizer in cassava cropping systems.

“…Praktik pemupukan termasuk dalam pengelolaan hara memengaruhi tingkat kesburan dan ketersediaan hara. Penggunaan pupuk anorganik dan organik seperti penambahan pupuk kendang sapi mampu meningkatkan efisiensi P sebesar 57% (Eckhardt et al, 2018) Penambahan pupuk kandang (kotoran ayam) dan pupuk anorganik (SP-36) di lahan ladang berdampak pada konsentrasi P tersedia yang lebih besar (meningkat 75-175 %) dibandingkan dengan P tersedia di lahan hutan pada berbagai kedalaman tanah (Fitria et al, 2021).…”

“…Pengelolaan dan masukan input seperti penggunaan pupuk anorganik dan organik menjadi penyebab tidak berbeda nyatanya status kesuburan tanah. Hal ini selaras dengan penelitian yang dilakukan oleh (Fitria, et al, 2021) saat membandingkan pengaruh posisi lereng terhadap penggunaan lahan hutan, agroforestri, dan dengan pertanian intensif.…”

Evaluation of soil nutrient fertility is needed to inform the level of nutrient availability in the soil. This evaluation is intended to mitigate land degraded or critical land. So that the area of critical land can be reduced by carrying out land management to maintain soil fertility. This research was conducted on 3 land uses, (i.e. fields, orchad and rice fields) with multiple cropping and monoculture management. The research was carried out with 3 repetitions at 4 slopes (i.e.0-8%, 8-15%, and 16-25%). Soil samples were taken compositely at two depths (i.e.0-20 and 20-30 cm). The parameters analyzed was soil chemical properties (i.e.pH H2O, total N, available of P, K, Organic C, and C/N). The results showed that land use had a significant effect (p<0.05) on availability of organic C, while slope had no significant effect (p>0.05) on soil chemical properties variables. pH H2O was significantly correlated (p < 0.05) with organic C (r = 0.

“…The evenness of the bacteria in the sample area was not different; this was demonstrated by the Simpson index value, which was relatively the same (Table 2). (Fitria and Kurniawan, 2021), and utilizing machines for crop management could modify the soil physicochemical properties, consequently altered the diversity of bacteria in the studied area. This finding was corresponding with another study conducted by Bissett et al (2011) and Suleiman et al (2013).…”

This study aimed at determining the community structure and diversity of soil bacteria in several land-use changes as an environmental bioindicator. This research was conducted in areas of intensive agriculture (PI), monoculture abandoned old-coffee plantation (KTT), mixed-young coffee plantation (HLS), and secondary forest/reference site (RS) in UB Forest (UBF) area, Malang, Indonesia. Soil samples were taken as a composite at three different points in each area using a soil ring at a depth of 0-20 cm. The 16S rRNA gene was used to determine the community structure, species richness, diversity, and ecological index (Chao1, Shannon, Simpson, ACE) of soil bacteria using the NGS approach. Statistical data were analysed using R and QIIME software. The community structure of soil bacteria at the phylum level displayed the same pattern in all study sites where Proteobacteria, Acidobacteria, Actinobacteria, Chloroflexi were the dominant groups. Conversely, the bacterial composition showed differences between study sites at the genus level. Alpha diversity in agricultural areas (PI, KTT, and HLS) was higher than forest area (RS), but it was not followed by bacterial beta diversity. The distinct soil bacteria composition and diversity were influenced by the physicochemical of soil properties in the studied area. Therefore, several bacterial taxa suggested being a potential bioindicator of forest soil degradation due to land-use change in this study. Soil bacterial indicators can be utilized to evaluate or monitor alteration of soil quality in terms of forest restoration or rehabilitation.
