Soil microaggregates as habitat for microorganisms
Biesgen, Danh (2022-07-27)Aggregation of soil particles is one of the most characteristic features of terrestrial soils and crucial for their functionality. Despite the high relevance of soil aggregates, only little is known about their genesis and ... -
Soil organic carbon pools and their spatial patterns: rapid assessment using mid-infrared spectroscopy
Bornemann, Ludger Clemens (2011-02-09)Soil organic carbon (SOC) plays an important role in global C cycling. Until today, the spatial patterns of individual SOC fractions are, however, largely undiscovered as traditional methods for their determination are too ... -
Soil water availability in agriculturally used wetlands of East Africa
Böhme, Beate (2015-07-07)Wetlands contribute increasingly to the food needs and income generation of the rural population in East Africa. The transformation of wetlands into farmland has gained momentum due to a growing food demand, upland shortages ... -
Solubility and Stability of Natural Food Colorants in Microemulsions
Abd El-Galeel, Mohamed Awad Saad (2002)Several microemulsion systems were prepared by using different natural oils such as peppermint oil alone or mixed with a common edible oils (soybean, peanut or rapeseed oil), different surfactants such as lecithin, monoolein ... -
Sorption, Transformation and Transport of Sulfadiazine in a loess and a sandy Soil
Sittig, Stephan (2014-12-10)Veterinary antibiotics are unintentionally introduced into the environment and therefore found in ground and surface water, soil and sediments, air, plants etc. They enter these compartments mainly via application of manure ... -
Soviet tractors vs. oxen: agroecology, agricultural policies and political discourse in Cuba
Figueroa Alfonso, Galia (2022-12-07)After the collapse of the socialist bloc in the late 1980s and early 1990s, the Cuban government was forced to forsake its plans to develop a modern agricultural sector, highly dependent on the intensive use of imported ... -
Spatial competition of learning agents in agricultural procurement markets
Khalili, Hamed (2019-07-15)Spatially dispersed farmers supply raw milk as the primary input to a small number of large dairy-processing firms. The spatial competition of processing firms has short- to long-term repercussions on farm and processor ... -
Spatial Targeting of Payments for Environmental Services in Costa Rica: A Site Selection Tool for Increasing Conservation Benefits
Wünscher, Tobias (2009-06-30)Payments for environmental services (PES) have become an increasingly popular market-based instrument to translate external, non-market environmental services into financial incentives for landowners to preserve the ... -
Spatial variation of biomass energy supply and demand in rural Nepal
Adhikari, Narayan Prasad (2017-02-24)In Nepal, the share of biomass in total energy consumption is about 88 % and of biomass for cooking and heating about 90 % in 76 % of the households. Fuelwood, crop residues and dung are the three main biomass types. The ... -
Spatially explicit modeling of sorghum (Sorghum bicolor (L.) Moench) production on complex terrain of a semi-arid region in Ghana using APSIM
Kpongor, Dilys Sefakor (2007)An increasing human population and decreasing fallow periods have resulted in a rapid decline in soil productivity in the semi-arid region of Ghana, which is characterized by low-input subsistence agriculture. Soils are ... -
Spatio-temporal Correlations of Terrestrial Laser Scanning: Raumzeitliche Korrelationen beim terrestrischen Laserscanning
Kauker, Stephanie; Holst, Christoph; Schwieger, Volker; Kuhlmann, Heiner; Schön, Steffen (2016)This contribution investigates correlations in terrestrial laser scanning on the scientific level. It summarizes recent approaches to model correlations, to develop measurement scenarios for the determination of correlations ... -
Spatio-temporal dynamics of bush-fire nutrient losses and atmospheric depositional gains across the northern savanna region of Ghana
Kugbe, Joseph Xorse (2012-10-12)This study estimates the nutrient balance between annual fire-induced nutrient transfers and bulk (wet plus dry) atmospheric nutrient deposition. In the subsistence-based and fertilizer-limited agriculture of northern Ghana ... -
Spatio-temporal landscape transformations in Southern Chile and its implications on ecosystem services supply and beneficiaries
Locher Krause, Karla Estela (2020-03-10)Human-induced global change has driven drastic modifications of ecosystems that could lead to unexpected and unprecedented transformations in the present and future decades. Current systems modifications increased the need ... -
Spatio-Temporal Registration Techniques for Agricultural Robots
Chebrolu, Nived (2021-06-16)A critical challenge that we face today is to meet the rising demand for food, feed, fiber, and fuel from an ever-growing world population. We must meet this demand within the limited arable land available to us and do so ... -
