Spatial variation of grassland canopy affects soil wetting patterns and preferential flow

Hydrological Processes, Volume 36, Issue 12, December 2022., 2022
Spatially heterogeneous canopy and pre‐event soil moisture conditions changed soil‐wetting patterns. Taller grass, together with drier soil, weakens soil moisture response, probably because of uneven water input and dryness induced preferential flow. Abstract Canopies shape net precipitation patterns, which are spatially heterogeneous and control soil ...

Single and multiple pin(s)-to-liquid discharges: connecting self-organization patterns and ROS production in liquids for plasma agronomy application [PDF]

arXiv, 2018
Pin-to-liquid discharges are investigated for the activation of liquids dedicated to agriculture applications. They are characterized through their electrical and optical properties, with a particular attention paid to their filaments and self-organized patterns occurring at the liquid interface.

GIS Applications in Agronomy

, 2016
Agronomy is a branch of agriculture that deals with soil and crop. Soil varies in space and is responsible for variation in the growth and yield of crops on the field. This variation in the yields of crops planted and monitored on the same parcel of land

National characterization of pesticide runoff and erosion potential to put USEPA standard ecological scenarios in context for pyrethroids

Integrated Environmental Assessment and Management, Volume 19, Issue 1, Page 175-190, January 2023., 2023
Abstract Decision‐making for pesticide registration by the US Environmental Protection Agency (USEPA) relies upon crop‐specific scenarios in a tiered framework. These standard modeling scenarios are stated to represent “…sites expected to produce runoff greater than would be expected at 90% of the sites for a given crop/use.” This study developed a ...

Jatropha Curcas Development as Intervention Potential to Tackling Land, Energy and Food Challenges of Rural Communities in Dryland Sub-Saharan Africa

Proceedings, 2020
Global population growth is placing increasing pressures on land for food and feed production as well as energy security. In particular in sub-Saharan Africa (SSA), these issues require urgent attention.

Toward a harmonized methodology to analyze field side effects of two pesticide products on earthworms at the EU level

Integrated Environmental Assessment and Management, Volume 19, Issue 1, Page 254-271, January 2023., 2023
Abstract Before plant protection product (PPP) marketing authorization, a risk assessment for nontarget soil organisms (e.g., earthworms) is required as part of Regulation (EC) No. 1107/2009. Following a stepwise approach, higher tier earthworm field studies are needed if they cannot demonstrate low long‐term risk based on laboratory studies.

Genetic diversity and community composition of arbuscular mycorrhizal fungi associated with root and rhizosphere soil of the pioneer plant Pueraria phaseoloides

iMeta, Volume 1, Issue 4, December 2022., 2022
The pioneering plant Pueraria phaseoloides had a strong modulation effect on arbuscular mycorrhizal fungi (AMF) communities. Irrespective of geographical location, community composition of AMF in rhizosphere soil differed from that of the root. Co‐occurrence network analysis revealed two AMF keystone species in rhizosphere soil (Acaulospora) and roots (

Modeling data with zero inflation and overdispersion using GAMLSSs [PDF]

arXiv, 2018
Count data with high frequencies of zeros are found in many areas, specially in biology. Statistical models to analyze such data started to be developed in the 80s and are still a topic of active research. Such models usually assume a response distribution that belongs to the exponential family of distributions and the analysis is performed under the ...

Analysis of a longitudinal multilevel experiment using GAMLSSs [PDF]

arXiv, 2018
The standard procedures for analysing hierarquical or grouped data are by (non)linear mixed models or generalized mixed models. However, the generalized additive models for location, scale and shape (GAMLSSs) also allow different types of random effects to be included in the model formulation. Even though already popular in many areas of research, this
