“…We therefore assessed the degradability of a single model exogenous OM source ( 13 C-labeled ryegrass residues) to see how land use changes affect stability of OC in soil. We hypothesize that the enhanced formation of pedogenic poorly crystalline Al under agricultural land use, as we previously confirmed (Anindita et al, 2022), results in a relative stabilization of the exogenous OM as compared to native forest or secondary forest. In doing so, we take account of the well-known phenomenon that labile OC inputs can accelerate the decomposition of native SOC, a process called positive priming (Chen et al, 2014), or conversely restrain decomposition of SOC and induce negative priming (Blagodatskaya et al, 2014;Qiao et al, 2014).…”

“…The mean annual temperature in the study sites is 19-21 • C, and mean annual precipitation ranges around 2000-3000 mm per year. Soils at sites NF-y and PF-i are andic Cambisols, and at the PF-o, AG-y, AG-i, and AG-o sites they are aluandic Andosols (Anindita et al, 2022). All soils contain silicate minerals (i.e., quartz, cristobalite, tridymite), gibbsite, albite, hornblende, 1 : 1 clay minerals, and non-crystalline materials (Anindita et al, 2022).…”

Abstract. Land use is recognized to impact soil geochemistry on the centennial to millennial timescale, with implications for the distribution and stability of soil organic carbon (SOC). Young volcanic soils in tropical areas are subject to much faster pedogenesis, noticeable already on the centennial or even decadal timescale. As land use is a recognized factor for soil formation, it is thus conceivable that even relatively recent land use conversion in such areas would already bear a significant impact on the resulting formed soils., e.g., in terms of content of pedogenic oxides. Very scarce observational evidence exists, so such indirect implications of land use on SOC cycling are largely unknown. We here investigated SOC fractions, substrate-specific mineralization (SOC or added plant residue), and net priming of SOC as a function of forest or agricultural land use on Indonesian volcanic soils. The content of oxalate-extracted Al (Alo) correlated well with organic carbon (OC) associated with sand-sized aggregates, particularly in the subsoil. The proportion of SOC in sand-sized ultrasonication-resistant (400 J mL−1) aggregates was also higher in agricultural land use compared to pine forest land use, and a likewise contrast existed for Alo. These combined observations suggest that enhanced formation of Al (hydr)oxides promoted aggregation and physical occlusion of OC. This was, importantly, also consistent with a relatively lesser degradability of SOC in the agricultural sites, though we found no likewise difference in degradability of added 13C-labeled ryegrass or in native SOC priming between the pine forest and agricultural land uses. We expected that amorphous Al content under agricultural land use would mainly have promoted mineral association of SOC compared to under pine forest land use but found no indications for this. Improved small-scale aggregation of tropical Andosols caused by conversion to agriculture and high carbon input via organic fertilizer may thus partially counter the otherwise expectable decline of SOC stocks following cultivation. Such indirect land use effects on the SOC balance appeared relevant for correct interpretation and prediction of the long-term C balance of (agro)ecosystems with soil subject to intense development, like the here-studied tropical Andosols.

“…Organic matter is slowly mineralized because of formed complexes with amorphous components that are found in volcanic parent materials. Amorphous components are short-range of Al (hydr) oxides that correlate well with organic carbon in agricultural soils (Anindita et al 2022). Organic matter builds up in the topsoil and causes the darkening of soil color.…”

This research was conducted in two highland areas of Bukidnon, Philippines: Miarayon, a sub-catchment of the upper Cagayan de Oro River; and Bendum, a sub-catchment of the upper Pulangui River. Due to their pyroclastic parent rock materials, soils in the upper Cagayan de Oro are classified as Andic Cambisol in open and convex positions, and Andic Umbrisol in concave and depressed positions. Soils in the upper Pulangui are classified as Pisoplinthic Acrisol, Ferralic Nitisol, and Acric Nitisol in areas with ultramafic rock parent materials, and Haplic Cambisol with pyroclastic deposits. Element contents in rocks were congruent to the total soil element content analysis results except for the total calcium which was higher in Miarayon. This is attributed to the parent rocks and soil management. Total magnesium and iron were highlighted in upper Pulangui soils because of their ultramafic rock parent materials. Soil management practices and length of cultivation were identified as anthropogenic factors affecting soil development. The constant application of organic fertilizers from chicken manure had caused the build-up of organic carbon and calcium in the topsoil of Miarayon soils. The differences in total organic carbon, total nitrogen, and potassium were highly significant, particularly in soil pH and total calcium between two sites in Miarayon. In Bendum, traces of phosphate fertilizers and lime application were evidenced by the relatively higher phosphorus and calcium content in topsoil. Tillage influenced the water conductivity in soils. Organic matter content increased the water-holding capacities of soil.

“…Compared with the natural factors such as climate and groundwater, human activities have a more rapid and profound impact on the soil characteristics [30][31][32]. Researchers have conducted a large number of experiments on saline water irrigation in arid and semi-arid areas, aiming to find appropriate and reasonable irrigation methods to actively and effectively regulate soil properties and reduce the risks of salinization [33,34]. Presently, certain experience has been gained for crops such as wheat, maize, cotton, and tomatoes [35][36][37].…”

Climate change and human activities lead to freshwater shortage, soil salinization, and food security crises in arable land. To explore the natural and irrigation factors on soil water and salt movement, this study quantitatively analyzed the dynamic characteristics of soil water and salt movement under precipitation, groundwater irrigation, and brackish water irrigation conditions for the next 30 years using Hydrus-1D model-based parameters obtained from the winter wheat–summer maize rotation experiments in the Yellow River Irrigation District. The results showed that precipitation was the key factor of climate change affecting soil water and salt migration, especially in the 0–20 cm soil layer. Under both SSP585 and SSP245 climate scenarios, rainfall in normal and wet years promoted salt leaching up to 1 m below the surface soil. But in dry years, salt washing treatment was required for the tillage layer to prevent salt accumulation. The higher the groundwater level was, the higher the soil water and salt content was in the 0–100 cm soil layer. In this soil layer, a 2 m groundwater level contributed 30% to wheat water needs, while a 3 m groundwater level contributed 18%, and no significant contribution was observed for a 4 m groundwater level. The salinity of the soil profile showed an overall increasing trend with irrigation using 1–3 g/L brackish water for 30 years. However, the salinity in the 0–100 cm soil layer was below the salt tolerance threshold of winter wheat and summer maize with salts accumulated in the 1–2 m soil layer. Considering the salinization of the root zone and crop water needs, it is recommended that the safe groundwater level for brackish water irrigation should be 3 m in the study region. This study provides scientific reference for groundwater–farmland ecosystems to utilize brackish water and treat saline–alkali lands.
