“…Heavy rainfall can occur between autumn and early spring (Sörensen, 2007; Kuzucuoğlu et al ., 2019). Dwarf scrubland and herb‐rich steppes characterize the present‐day vegetation on the plateaus, the foothills show an open steppe vegetation with scattered oak and fruit trees, and the plains are intensively used for arable farming made possible by the water of the Atatürk Dam (Rosen, 1997; Özcan et al ., 2018; Kuzucuoğlu, 2019; Kuzucuoğlu et al ., 2019).…”

“…Leptosols, Calcisols, and Cambisols have developed in the carbonate‐rich parent material of the plateaus and slopes. The plains are characterized by Vertisols (Özcan et al ., 2018; Akça et al ., 2018a, 2018b). Recently published results regarding present‐day landform characteristics (Knitter et al ., 2019) and Holocene relief‐forming processes (Nykamp et al ., 2020a) show that the hillslopes of the headwater catchments are characterized by periodic sheet flow and soil creep processes, forming colluvial deposits at the slope toes of the valleys.…”

This study presents a meta‐analysis of radiocarbon ages for the environs of Göbekli Tepe – one of the oldest monumental structures worldwide – using cumulative probability functions to diachronically assess phases of geomorphodynamic activity as controlled by natural or anthropogenic drivers. We employ sediment cascades as a heuristic framework to study the complex responses of the geomorphological system to various triggers at local to supra‐regional scales. Possible triggers include climatic variability as documented by supra‐regional hydroclimatic proxy data, regional demographic trends, and local to regional socioeconomic developments such as the emergence of sedentism or the introduction and dispersal of livestock herding. Our results show that phases of intensified geomorphodynamic activity occurred between ca. 7.4–7.0 and 5.8–3.3 ka BP. These phases roughly coincide with phases of population growth in southern Turkey and climatic variations in Turkey and the Levant. The phase between ca. 5.8–3.3 ka BP also corresponds to the time when organized agriculture and the seeder plough were introduced. Also, the identified phases are in agreement with the general trend of varying geomorphodynamic activity in the Eastern Mediterranean as driven by human impact and climatic change. However, neither the Younger Dryas–Holocene transition nor the development of herding during the Pre‐Pottery Neolithic left a clear signature. We demonstrate how the different depositional environments in the studied landscape compartments vary with respect to their spatiotemporal coverage and discuss challenges when trying to understand processes that once shaped landscapes of past societies. © 2020 The Authors.

“…Therefore, impeded drainage is not a limiting factor for rice crops but is found to be a limiting factor for corn and soybean crops. Soil with a high clay content has the potential to become compacted and to have slow drainage and permeability if not treated properly, especially for corn and soybean crops that require good aeration [15][16] Poor drainage and slow permeability can increase surface flow, especially in the rainy season, and this has the potential to cause increased erosion. other types).…”

This study aims to determine the potential and limitations of land in Ngawi District, East Java, Indonesia, for cultivating rice, corn, and soybeans. The research consists of a four-stage field study conducted in Ngawi Regency: (1) organization of land units; (2) determination of observation points through stratified proportional sampling for each land unit; (3) field surveys; and (4) laboratory analysis. The land evaluation was conducted in accordance with the FAO Guidelines for Land Evaluation for Rainfed Agriculture. The results of the research indicate that 46,417.7 ha (88.1%) of the land area is highly suitable (S1) for rice and 49,286.6 ha (72.1%) is marginally suitable (S3) for corn due to poor drainage. Approximately 62,499 ha (91.4% of the total land area) are marginally suitable (S3) for soybean cultivation. There were suggested five models of land management: (1) intensive rice farming; (2) a relay cropping system for rice-corn or rice-soybeans; (3) multiple cropping systems for corn, soybeans, or rice; (4) a mono-cultural system for rice, corn, or soybeans; and (5) an agroforestry system for Albizia chinensis, corn, and soybeans. Farmers’ awareness of organic management is crucial for enhancing land productivity and maintaining soil fertility in Ngawi Regency.

“…Therefore, managing turfgrass in vertisol has a particular chance for rooting development of seashore paspalum. Vertisol has a clay texture with high negative colloid, thus having a high cation exchange capacity (Özcan et al 2018;Dudek et al 2019). The soil has a moderate total N of 0.21%, a high CEC of 25.1 Me/100g, and a high clay content dominated by type 2:1 clay minerals (Hailu et al 2015).…”

Abstract. Rahayu, Ariyanto DP, Usrotin AH, Hatami FR, Mo YG. 2023. Assessment of turf quality in Paspalum vaginatum Sw. accessions of Sumatra, Java, and Bali (Indonesia) with clay and amended sand growing media. Biodiversitas 24: 1650-1658. Seashore paspalum (Paspalum vaginatum Sw.) is a selected turfgrass species in the FIFA football world cup Qatar 2022. The choice considers its turf quality, growth habit, quick recovery from damage, tolerance in warm conditions, and low water consumption. Since the breeding program of seashore paspalum worldwide still needs to be improved and is yet to start in Indonesia, we suppose that in the future, seashore paspalum will become a favorite turfgrass industry. Previous studies showed that Indonesia has many accessions to the germplasm of seashore paspalum. This study aimed to find superior mother lines of Indonesian germplasm accession by select of visual and functional quality using clay soil of vertisol and vertisol-amended sand as growing media for quality evaluation. This study was a wild-type collection followed by a plot experiment using Randomized Complete Block Design. In this experiment, the control was using a commercialized cultivar. Seashore paspalum accessions were collected from Java, Bali, and Sumatra Indonesian islands. Observation of variables were visual qualities, i.e., tiller density, color, leaf texture, uniformity, and functional quality, i.e., surface covering, recoverability, clippings dry weight, root length, root dry weight. The National Turfgrass Evaluation Program (NTEP) rated those qualities by scoring. The quality index of turfgrass used a rating score formulated from a visual and functional quality score. The data were analyzed using DMRT and T-test. Results showed that growing paspalum in clay-amended sand media showed a better recovery rate than the accessions grown in vertisol media. Mowing the grass can reduce plant height and leaf texture, and increases the clipping dry weight. Sand amendment to vertisol soil can improve the seashore paspalum visual qualities, i.e., leaf texture, tiller density, color score, and functional quality, such as root length. Seashore paspalum accessions vary in quality, i.e., visual and functional. Native accessions have a better recovery rate, higher tiller density, and uniformity than the control but a higher clipping yield. Bogor accession had faster soil surface coverage, Siak accession had a high recovery rate. Rumbei accession was the highest clipping dry weight, fast land cover, and high root dry weight. The accessions of Siak and Rumbei have higher quality index than the control after mowing. Siak accession performed better in vertisol, whereas Rumbei accession performed better in vertisol-amended sand. The performance of Rumbai and Siak accessions showed that seashore paspalum from Sumatra has better characteristics than Java and Bali and is promising for further cultivar development.
