Concerns about the sustainability of inorganic fertilizers necessitate the characterization of alternative P source materials for agronomic P-efficiencies and P losses via leaching. Firstly, this study examined nutrient compositions including P speciation of seven soil amendments: sewage sludge (SS), anaerobic digestate (AD), green compost (GC), food waste compost (FWC), chicken manure (CM), bi...

The large-scale commercial cultivation of transgenic crops has undergone a steady increase since their introduction 10 years ago. Most of these crops bear introduced traits that are of agronomic importance, such as herbicide or insect resistance. These traits are likely to impact upon the use of pesticides on these crops, as well as the pesticide market as a whole. Organizations like USDA-ERS a...

Plants in the field are exposed to varying light and moisture. Agronomic improvement requires knowledge of whole-plant phenotypes expressed in response to simultaneous variation in these essential resources. Most phenotypes, however, have been described from experiments where resources are varied singularly. To test the importance of varying shoot and root resources for phenotyping studies, sis...

In Brassica napus breeding, traits related to commercial success are of highest importance for plant breeders. However, such traits can only be assessed in an advanced developmental stage. Molecular markers genetically linked to such traits have the potential to accelerate the breeding process of B. napus by marker-assisted selection. Therefore, the objectives of this study were to identify (i)...

The role agronomy plays in the management of phytotechnologies is a significant example of the answers that the agrosciences can offer to the issues of society in the field of Green Remediation. This paper reports a study designed to test how the principles of classical plant growth analysis can be used in the field of phytoremediation. In the framework of a phytoremediation field trial set up ...

Uncovering the genetic basis of agronomic traits in wheat landraces is important for ensuring global food security via the development of improved varieties. Here, 723 wheat landraces from 10 Chinese agro-ecological zones were evaluated for 23 agronomic traits in six environments. All accessions could be clustered into five subgroups based on phenotypic data via discriminant function analysis, ...

irrigation management transfer to farmers is one of the important and necessary issues for irrigation planners globally. irrigation management transfer or participatory irrigation management by water users’ associations (wua) is a widespread strategy in the world and a good way to remove the country's irrigation and drainage systems problems. the main objective of this research was respons...

A spatial analysis of Agriotes sordidus (Illiger) (Coleoptera Elateridae) was carried out on data collected by means of pheromone traps in a farm of 500 hectares in northern Italy. The main objective of the paper was to analyse the spatial distribution of this economic pest, in order to optimise the monitoring; another aim was to understanding the spatial patterns of this insect in relation to ...

Clear Lake is on Iowa's list of impaired water bodies because of high P concentration. This study assessed soil-test phosphorus (STP), management practices, and P loads from its agricultural watershed. Management practice histories and STP for eight basins were surveyed in 1999. Soil samples (15-cm depth) were analyzed for STP with agronomic [Bray P1 (BP), Olsen (OP), Mehlich 3 (M3P) and enviro...
