“…It has been noted in another study that landforms and land use had impact on soil chemical properties [57]. Similarly, differences in soil micronutrients variability were observed in the Usambara Mountains in Tanzania due to differences in landforms [18].…”

Soil micronutrients are important elements for plant growth despite being required in small quantities. Deficiency of micronutrients can result in severe crop failure while excess levels can lead to health hazards; therefore, investigating their status in agricultural land is crucial. The correlated micronutrients implied that they were affected by similar factors. Soil pH correlated positively with B, Fe, and Mn and negatively with Cu and Zn, hence probably influencing their availability. Therefore, the need for sustaining micronutrient at sufficient levels is crucial. Management interventions may include moderating soil pH by reducing acidity through liming in the higher elevations and incorporation of organic matter in the lowlands.

“…Soil organic carbon is an important indicator of physical characteristics of soils with various land use types. Contents of soil organic carbon have been reported to range from 0.55 to 10.8% in bush land and forest plantations in the plain and plateau, 1.03 to 6.34% in cultivated mid-slopes and lower slopes of the plateau, and around 4.5% in the vegetable growing valley bottoms in Tanzania [26]. Carbon sequestration mitigates climate change as one of the multiple ecosystem services for healthy soil [27].…”

This study examined carbon footprint as an indicator of soil health at spatiotemporal scales with different land use types and varying soil depths in Morogoro, representing the eastern agroecological zone of Tanzania. Soils are highly weathered and acidic. The specific objectives were twofold: (1) To quantify soil organic carbon (SOC) at varying soil depths (0–15 cm, 15–30 cm) in contrasting land use types, including tractor cultivated, hand-hoe cultivated, ranch land, and reserved/bare land type; (2) To predict carbon management indices (CMI) of the studied land use types through regresses SOC, carbon pool index (CPI), and lability index (LI) at varying soil depths. Composite soil samples were based on transects of three main plots each (replicates) of 20 m by 50 m. Results showed that land use types and soil depths significantly (P <0.001) affected SOC (3.4%) and CMI (126.3). Hand hoe cultivated land at 0–15 cm recorded CMI of 259.8. Regression analysis showed an increase in CMI ranging from 97% to 99%, with standard error ranging from 2.177 to 46.096. Similar trends, but with disparity magnitudes in regressed parameters provide useful insight into transformations of organic carbon in contrasting land use types.

“…Over fertilization with phosphate fertilizer or high phosphorus content in soil may decrease the uptake of Zinc or other micronutrients by plants (Dadhich and Somani, 2007; [10] Kizilgoz and Sakin, 2010) [24] . Micronutrient deficiency generally lead to crop failure (Meliyo et al, 2015) [33] , hence advanced crop and soil management practices including micronutrient application (Garcia-Ocampo, 2012 [16] ; Kabata-Pendias and Pendias, 2001) [19] is essential for enhancing crop yield. Micronutrient enhances the macronutrient use efficiency of crop but injudicious continuous application of micronutrient may also cause toxic and hazardous effect of plant (Sarkar et al, 2010) [43] .…”
