Dynamics of Phosphorus Availability and Uptake in Hydroponics and Soils
(2024-12-09)The availability of phosphorus (P) in terrestrial ecosystems is primarily determined by plant genotypes and soil physiochemical characteristics that influence the chemical forms of P in soil and its biotransformation by ... -
Soil Multi-Meta-Omics: Unraveling microbial regulation at three post-genomic levels
(2024-04-19)Soil functions are key in all ecosystems globally. Specifically soils play a pivotal role in ecosystem biogeochemical cycles, sequestering but also mineralizing carbon (C), and in this context releasing nutrients from ... -
Functions of root mucilage for plant and soil: Quantifying its exudation, characterizing its composition, and assessing its influence on plant water and nitrogen uptake and rhizosphere microorganisms
(2022-12-06)Plants modify the chemical, biological, and physical properties of the soil around their roots by releasing a set of substances called rhizodeposits. Mucilage, a viscoelastic high-molecular-weight substance exuded by ... -
Biogeochemical mechanisms of P and C cycling in rice-paddy systems driven by enzymatic reactions and the Fe(III)-Fe(II) redox wheel
(2022-11-16)Rice (Oryza sativa L.) is one of the predominant food sources and is mainly cultivated on flooded paddy soils. However, finite and dwindling phosphate rock, the main source of phosphorus (P) fertilizer, becomes increasingly ... -
Studies on improving phosphorus use efficiency of potato: effects on plant growth, physiology, and quality of tubers
(2021-11-18)Plants develop different strategies in response to low and high P supply. Potato has a low P use efficiency (PUE) compared to other crops, which is caused by its limited root system. Therefore, it is necessary to gain more ... -
Biotic and abiotic controls on microbial activity, functionality and processes in soil hotspots
(2021-08-23)When a carbon (C) source is added to a soil volume and causes microorganisms to thrive, a microbial hotspot is formed — a microsite with much higher process rates than the surrounding bulk soil. The formation, size, and ... -
Mycorrhization and Warming Modulate Soil Organic Matter Stability
(2021-06-24)Soil organic matter (SOM) is the primary source of plant-available nutrients, as well as a substantial carbon (C) reservoir in terrestrial ecosystems. Maintenance of SOM levels is therefore critical for ecosystem sustainability. ... -
Mitigating N2O emission from arable soils
(2021-04-23)Nitrous oxide (N2O) is an important greenhouse gas which contributes to climate change and ozone depletion. Mineral N fertilizers are one of the most important sources of N2O emission in agricultural systems. Enhanced-efficiency ... -
Impact of carbon and nitrogen application in paddy-soil ecosystem: 13,14C labeling, zymography, pH mapping and PLFA
(2020-05-29)Rice (Oryza sativa L.), a major cereal crop, is cultivated on more than 140 million hectares worldwide. Consequently, rice growing paddy fields are major consumers of nitrogen (N) fertilizer and the biggest users of ... -
Potential Impact of Increasing Ammonia Concentrations upon Microbial Population Dynamics in Anaerobic Meso- and Thermophilic driven Fermenters
(2020-02-06)Anaerobic digestion is the process of decomposition of organic matter by a microbial consortium in an oxygen-free environment. The produced biogas from this process is composed of methane, carbon dioxide, nitrogen, oxygen, ... -
Carbon Turnover in Subsoil Hotspots: Are Biopores more than Voids?
(2019-03-21)The soil below the ploughed horizon of cropland, i.e. the subsoil, could be a large sink for carbon (C) and a valuable source of mineral-bound nutrients. C dynamics in subsoils need to be thoroughly understood to enable ... -
Rhizosphere engineering Improving plant tolerance to drought by modifying the physical and biological properties of the rhizosphere
(2018-10-23)Among various biotic and abiotic stresses, drought is one of the most limiting factors compromising plant growth and crop productivity. Mobility and availability of nutrients are controlling factors for plant growth and ... -
Assessment of genetic and nutritional diversity, and salinity tolerance of Kenyan guava (Psidium guajava L.): an underutilized naturalized fruit species
(2018-08-07)Common guava (Psidium guajava L.) fruit has a significant nutritional and medicinal potential besides its economic importance, yet is still underutilized in terms of production and consumption. The current global guava ... -
Unfavorable environmental conditions: Consequences for microbial metabolism and C stabilization in soil
(2017-11-21)Soil microorganisms are primary drivers of biogeochemical cycles, making them an important link between pedosphere and atmosphere. Soil microbes control the carbon (C) transfer from terrestrial ecosystem to the atmosphere ...
