Efficacy and selectivity of pre-em herbicide on dependence of soil types and precipitation in sunflower crop

Agraarteadus, 2021
During the growing seasons in 2018 and 2019, two field trials were conducted to estimate how precipitation affects the efficacy of PRE-em herbicides in sunflower crop grown on different soil types.

A modification of the mixed form of Richards equation and its application in vertically inhomogeneous soils [PDF]

, 2011
Recently, new soil data maps were developed, which include vertical soil properties like soil type. Implementing those into a multilayer Soil-Vegetation-Atmosphere-Transfer (SVAT) scheme, discontinuities in the water content occur at the interface ...

Effect of soil storage at 4 °C on the calorespirometric measurements of soil microbial metabolism

AIMS Microbiology, 2017
Soil samples must usually be stored for a time between collection and measurements of microbial metabolic properties. However, little is known about the influence of storage conditions on microbial metabolism when studied by calorespirometry ...

Developing a reliable strategy to infer the effective soil hydraulic properties from field evaporation experiments for agro-hydrological models [PDF]

, 2009
The Richards equation has been widely used for simulating soil water movement. However, the take-up of agro-hydrological models using the basic theory of soil water flow for optimizing irrigation, fertilizer and pesticide practices is still low.

A Ready-to-Use Single- and Duplex-TaqMan-qPCR Assay to Detect and Quantify the Biocontrol Agents Trichoderma asperellum and Trichoderma gamsii

Frontiers in Microbiology, 2018
Trichoderma asperellum strain icc012 and Trichoderma gamsii strain icc080, the microbial active ingredients of RemedierTM (ISAGRO, Novara, Italy), are biocontrol agents (BCAs) employable for crop protection against a wide range of fungal pathogens ...

Characterization of fungal carbonyl sulfide hydrolase belonging to clade D β‐carbonic anhydrase

FEBS Letters, Volume 599, Issue 8, Page 1146-1158, April 2025.
Here, we performed a functional analysis of the fungal enzymes belonging to clade D of the β‐class carbonic anhydrase family (β‐D‐CA). The β‐D‐CAs in the basidiomycete Gloeophyllum trabeum and the ascomycete Trichoderma harzianum showed very low activity in the hydration of CO2 but exhibited high activity in the hydrolysis of carbonyl sulfide (COS ...

Winter soil respiration in a humid temperate forest: The roles of moisture, temperature, and snowpack [PDF]

, 2016
Winter soil respiration at midlatitudes can comprise a substantial portion of annual ecosystem carbon loss. However, winter soil carbon dynamics in these areas, which are often characterized by shallow snow cover, are poorly understood due to infrequent ...

Robotic Irrigation Water Management: Estimating Soil Moisture Content by Feel and Appearance [PDF]

arXiv, 2022
In this paper we propose a robotic system for Irrigation Water Management (IWM) in a structured robotic greenhouse environment. A commercially available robotic manipulator is equipped with an RGB-D camera and a soil moisture sensor. The two are used to automate the procedure known as "feel and appearance method", which is a way of monitoring soil ...

Interaction between bacterial phytochromes Agp1 and Agp2 of Agrobacterium fabrum by fluorescence resonance energy transfer and docking studies

FEBS Letters, Volume 599, Issue 6, Page 848-865, March 2025.
The interaction between Agrobacterium fabrum phytochromes Agp1 and Agp2 was studied using FRET. Full‐length and truncated proteins with varied label positions provided spatial insights, narrowing down from many docking models to three. These models explain Agp2's reduction in Agp1 autophosphorylation, with Arg83 of Agp2 specifically evolved to interact

Tolerable versus actual soil erosion rates in Europe [PDF]

, 2009
Erosion is a major threat to soil resources in Europe, and may impair their ability to deliver a range of ecosystem goods and services. This is reflected by the European Commission's Thematic Strategy for Soil Protection, which recommends an indicator ...
