Abstract:In intensive, open horticultural crop production systems, quantities of water and soluble fertilizers are convected by gravitational and evaporative flow through the plant root zone, with only a small fraction being captured by the plant root system. Principles and concepts developed in creating a protected diffusion zone (PDZ) within the closed, insulated pallet system (CIPS) have been extrapolated to create a protected zone for fertilizer diffusion in a surface-irrigated plant container or open field… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
