“…However, in the lowland zone the soil pH negatively related with total N. Furthermore, the soil pH negatively but not significantly correlated with OC in all zones. Findings, e.g., by Wibowo & Kasno (2021); Bi et al (2018);and Zhou et al (2019), revealed a negative and significant relationship between soil pH and OC, similarly to the present study. This indicates that a low pH promotes the formation of organic matter.…”

In the northern part of Tanzania, the slopes of Mount (Mt.) Kilimanjaro are the most important areas, both in terms of socio-economic development and ecological succession. The main agricultural systems in the area are banana-based (in the highlands) and maize-based (in the lowlands), with strong interlinkage between them via residual transfer from the lowlands to the mountains. This study assessed the soil fertility status between the two contrasting farming areas of highland and lowland farms in Hai district along the slopes of Mt. Kilimanjaro. To achieve this, smallholder farmers along the slope [from above 1000 meters above sea level (m.a.s.l) banana-based down to maize-based, i.e., less than 1000 m.a.s.l] who practice crop residual transfer from maize-based to banana-based farming systems were selected. Qualitative information regarding the demographics, farming practices, and soil fertility management in the two areas were gathered using a semi-structured questionnaire. Soils from both areas (highland and lowland farms) were collected and analyzed in the laboratory for the key soil properties. The demographic results show that agriculture is mostly done by adults and elders (>40 years old). Manure was most commonly reported to be used in the highlands, while inorganic fertilizers were mainly used in lowland areas. The major challenges for soil fertility management are a shortage of manure and high cost of inorganic fertilizers. The results of soil nutrients revealed that lowland zones (>1000 m.a.s.l) had significantly (p< 0.01) lower levels of nitrogen (0.14%) and organic carbon (OC) (1.22%) compared with highland zones. Extractable phosphorus (P) was significantly lower in both the highland and lowland zones, at 9.3 mg kg-1 and 8.2 mg kg-1, respectively, compared with other nutrients. However, potassium (K+) was significantly (p<0.01) lower [0.34 cmol (+) kg-1] in the highland zone compared to lowland areas. The data show that there is a severe depletion of soil nutrients in the lowland area of Hai district. Notwithstanding the efforts of the small-holder farmers; the study comes to the conclusion that increasing agricultural yield and the sustainability of farming systems require replenishing the nutrients in the soil along the slope of Mount Kilimanjaro.

“…While the C-organic should be at least 4 %, the average rate in samples was 1.35 % with the lowest quantity of 0.62 and the highest of 2.67 -these figures characterize badly-damaged soil. This finding corroborates an earlier report that more than 77 % of paddy fields in Java had low organic carbon [26,67]. That there is inadequate vegetation due to monoculture in the research sites and that farmers barely recover soil biomass are deduced to be the reasons [2, 49,50].…”

“…SOC is the key indicator of soil quality and agricultural sustainability [71]. SOC content relies heavily on nitrogen binding in soil [2,67]. The SOC test results came out between 1.07 % and 4.62 % for all 18 samples, and seven samples reached the level of as low as 1.65 %.…”

Soil is paramount to sustaining living in biomass production, water quality control, climatic mitigation, and biodiversity endurance. Closely associated with sustainable agriculture, it degrades soil in the long run, robbing the soil of its production capacity and food-generating ability. In Probolinggo, a regency in Indonesia, intensifying the use of chemical fertilizers and pesticides yet a declining trend in yield production was discovered. This research analyzed the acid, nitrogen, organic carbon, and nutrients focusing on phosphor, potassium, iron, and manganese contents. Organic carbon/nitrogen ratio, soil organic compound rate, and cation exchange capacity were also discussed in order to illustrate the correlations among chemical substances and their roles in soil and plant maintenance. While such a study has yet to be performed in Probolinggo, the results should show the degree of land deterioration and future attempts at damage control and correction open to facilitate. Employing a simple random method, soil and plant samples were collected from 18 villages in six districts and their chemical contents were compared to the standard set in Government Regulations No 150/2000. The results showed low N-total, P-Bray, P-Olsen, K, C-Organic, and C/N ratio availabilities at 0.18, 13.88, 14.41, 0.37, 1.36, and 7.38 respectively, contrasted to high rates on pH (5.94), Fe (153.46 mg kg–1) and Mn (37.96 mg kg–1). Biomass production is conclusively imperative to fix the land composition and meet the plant nutrient requirements through an organic approach; fertilizers from digester biogas are therefore recommended. This action requires field agricultural advisors to raise awareness of sustainable agriculture.

“…It can be seen that the C-organic and the pH of the cattle manure are very high and alkaline. This finding is supported [12] that C-organic has a positive correlation and significantly increases the availability of nitrogen in the soil. Increasing the dose of nitrogen could increase the growth and biomass of Gotu kola at a dose of 60 kg/ha N giving the maximum number of Gotu kola leaves [13].…”

Asiatic pennywort (Centella asiatica L. Urb) is one of the medicinal plants, it had a large spread, especially in tropical and subtropical areas. This study aimed to determine the dose of liquid organic fertilizer (LOF), cattle manure, and their interaction to increase the biomass of asiatic pennywort. This study was conducted at Medan Selayang Sub-district with an altitude ± 25 m ASL from March to May 2022. This study used a factorial randomized block design (RBD), the first factor was the cattle manure: 0; 3.375; 6.75; and 10.125 tons/ha, and the second factor was the LOF application: 0; 1.5; 3; and 4,5 ml/ l. The data were analyzed by an ANOVA, and the mean was continued by a DMRT at P<0.05. The results showed that the application of cattle manure at a dose of 6.75 to 10.125 tons/ha could be increased the number of leaves and the number of primary tendrils by 40.98% and 35.02%, respectively. The LOF-treated at doses of 3 to 4.5 ml/l could be increased petiole length, number of leaves, and number of primary tendrils were 32.94; 60.49; 64.73%. The K0P2 and K3P3 interactions could be increased stalk length by 93.57% respectively.
