What You Should Know About Corten Steel Containers
The Wet-Dry Cycle A requirement for the formation of the protective patina is regular wetting and curing of the surface. The weathering process is dependent on the aggressiveness of the environment into which the steel is placed, and wet and salt-laden air environments may prevent the formation of the protective layer, making adequate …
Fundamentals of Container Media Management: Part I
container-grown plants requires an understanding of the unique environment found in containers and how it is affected by the physical and chemical properties of the growing media. Compared with roots of plants growing in the field, those growing in containers are exposed to a more stressful environment. The following examples help to

Fundamentals of Container Media Management: Part I
The use of mineral (field) soil as a component of container media is not recommended for reasons that include heavy weight; non-uniform particle size distribution and small pore size; poor drainage; variable chemical properties; non sterile, potential carrier of insects; weeds and diseases.
The CORSMAL benchmark for the prediction of the properties of containers
The contactless estimation of the weight of a container and the amount of its content manipulated by a person are key pre-requisites for safe human-to-robot handovers. However, opaqueness and transparencies of the container and the content, and variability of materials, shapes, and sizes, make this estimation difficult. In this paper, we present a …

Factors Affecting Quality of Composts for Utilization in Container Media
Abstract A variety of publications from the United States (9, 10, 16, 22, 28), Norway (27), Belgium (4, 5, 6), Finland (18), and Japan (30) have discussed composting of tree barks for use in container media. Although differences in properties of bark from tree species are considerable, established methods for production of high quality composts are …
