“…Accordingly, the C/N ratio of the surface soils across the topography may be considered below the optimum range in all soils for microbial needs except in AYB-1 and 6. Sakin et al (2010) found the C/N ratio of arable soils much lower than 10, might indicate N input from external sources, mainly from fertilizers and deposits. On the other hand, prolonged intensive farming also led to a continuous increase in soil nitrogen (Deng et al 2014;Yang et al 2021).…”

Currently, soil characterization and classification are becoming the primary source of information for precision agriculture, land use planning, and management. Thus, this study was focused on perusing the landscape-scale spatial variation of soils in data-scarce areas using toposequence-based ground sampling to characterize and classify the soils. Six typical profiles representing major landforms were opened and studied for their morphological characteristics and physical and chemical properties. Results indicated that the soils were shallow to very deep in depth, moderately acidic to moderately alkaline in soil reaction, non-saline, and clay to sandy loam in texture. The soils were found to be very low to low in organic carbon, very low to medium in total nitrogen , low to medium in available P, very low in available S, very low to low in available B, high to very high in CEC and very low to very high in base saturation. The soils were found to tbe deficient in Zn but sufficient in Fe, Cu, and Mn. Following the field survey and soil analytical results, five main reference soil groups, mollic Leptosols (Eutric), Prothovertio Luvisols (Clayic, Aric, Escalic), Skeletic Fluvisols (Arenic, Densic), Haplic Leptosols (Skeletic), Haplic Vertisols (Endocalcaric, Ochric), and Haplic Cambisols (Arenic, Aric) were identified in the different parts of the topographic positions. Pedon - 2, 3, 5, and 6 were classified in I to IV land capability class (LCC) and grouped as arable land with some limitations. They were in suitable to a marginally suitable range. The severe constraints to crop cultivation in the area were low fertility, erosion hazard, and climate for all soil units. Therefore, application of manure and compost alongwith chemical fertilizer, reducing complete crop residue removal, and soil and water conservation measures are essential to overcome these common and other limitations.

The characterization of soil landscapes is becoming increasingly important for making decisions regarding site-specific agriculture systems and soil management. This study was initiated for the purpose of identifying landscape-scale spatial soil variation using a toposequence model so that site-specific fertilization could be achieved. According to the finding, the soils were shallow to very deep in depth, moderately acidic to moderately alkaline in soil reaction, nonsaline in salinity, and clay to sandy loam in texture. The soils were found very low to low levels in most soil nutrients, very low to very high levels of base saturation, and deficient in zinc but have adequate levels of iron, copper, and manganese. The soil exchange complex was mainly dominated by Ca and Mg where the order of occurrence was Ca > mg > K > Na. The CEC values were in high to very high range. Following the field survey and soil analytical results, five main reference soil groups of the World Soil Resource Base—Leptosols (56%), Luvisols (8.5%), Fluvisols (14.4%), Vertisols (13%), and Cambisol (8.2%)—were identified and mapped. Leptosols cover the largest landmass of the watershed and mostly found at the summit and hill back slopes. On the other hand, Luvisols, Fluvisols, Vertisols, and Cambisols were found on the middle and foot slopes. According to the findings, the variation in soil source indicating that topography is the primary pedogenic element in the formation of the soil in the watershed that was under research. Therefore, having local-scale-specific soil information can assist the site-specific application of soil nutrients and amendments based on spatial variability which is tailored to the soil requirements.

“…At 25 cm depth of walnut gardens soils, SOC, TN, and C: N was 3 g kg -1 , 0.33 g kg -1 , and 31.2, respectively (Kashi et al, 2016). C: N ratios range from 8:1 to 15:1 in the Mississippi River Delta region of eastern Arkansas (Brady and Weil, 2008) and between 4.32:1 and 6.04:1 in Harran plain soils (Sakin et al, 2011b). It is known that C: N ratio was induced by low rainwater, full resolution, extraction rates, or extreme cultivation techniques.…”

“…While the C: N ratio is high, the decomposition of organic matter (OM) is slow, and while the C: N ratio is small, the decomposition takes place quickly. In short, the C: N ratios of soils are important in terms of the mineralization of OM (Sakin and Sakin, 2014). If the C: N ratio of the organic substance is more than 30, nitrogen immobilization occurs at the beginning of decomposition.…”

Soil organic carbon (SOC) and total nitrogen (TN) have a very important role in sustainable soil quality, crop production, and environmental impacts, and determining of carbon nitrogen ratio (C: N ratio) is very important for creating data banks in terms of ecosystem functions. Plants influence the interaction of SOC and TN, as well as ecosystem yield and the continental carbon cycle. Climate, atmosphere, and land-use change are all included in numerical models of the carbon (C) and nitrogen (N) cycles. This study was conducted to determine the SOC and TN stocks, the C: N ratio and their relationships with the soil properties of olive orchards in Aliaga, Bayindir, Bergama, Dikili, Foca, Karaburun, Kemalpasa, Menderes, Menemen, Odemis, Seferihisar, Selcuk, Tire, Torbali and Urla provinces of Izmir in Turkey. For this purpose, 129 soil samples were taken from 0-30 cm depth. The texture, pH, EC, lime, OM, SOC and TN content and stocks, Bulk density (Db) was determined. Db and C: N ratio varied between 0.84-1.31 g cm-3, 5.17-80.50, and SOC density and stocks changed between 4.00-53.00 mg cm-3, 1.25-1.59 kg m-2, N density and stocks between 0.09-2.66 mg cm-3, 0.03-0.80 kg m-2, respectively. The highest BD was obtained from Tire, the highest SOC stocks from Karaburun, the highest TN from Seferihisar and Karaburun. The very small bulk density which is negatively associated with OM and clay is an important feature. The SOC contents were higher in relatively heavy rainfall regions. SOC and soil texture have a strong relationship. As a result, texture, precipitation, temperature, soil depths, and regeneration of soil affect the SOC and TN stocks. The results may be effective in terms of sustainable soil quality and ecosystem functions for olive cultivation.
