This document is about interpreting electrical conductivity (EC) measurements in soils and container media to manage soluble salts from fertilizers, irrigation water, and storm events. It explains how excessive salts affect plant growth, provides guidelines for testing and interpreting EC values, and offers practical recommendations for leaching salts and preventing salt accumulation in landscapes, crops, and containerized plants. First printed April 1993.

This publication aims to highlight the inefficiencies of using a single-rate, EC-based, NFT nutrient dosing practice for lettuce production throughout the growing season. The information contained in this document is relevant to a diverse audience, including students, researchers, Extension agents who have some level of understanding about controlled environment agriculture (CEA) and water and fertilizer management techniques, and hydroponic growers. Written by Kelsey Vought, Haimanote Bayabil, and Ana Martin-Ryals, and published by the UF/IFAS Department of Agricultural and Biological Engineering, February 2025.

Developed technologies for the desalination of seawater and brackish groundwater supplies have been demonstrated to be technically feasible, economically viable, and reliable; meanwhile, emerging technologies are still in the pilot or small-scale stages. The total installed capacity of desalination plants in the United States has expanded from around 302 million gallons per day (MGD) in 2009 to about 479 MGD in 2022. Florida leads the nation in desalination capacity, having more than 130 desalination plants. Environmental issues related to desalination are a significant factor in designing and implementing desalination technologies. Their projects require an environmental impact assessment (EIA) study to determine how the project can affect the air, land, and marine environments by considering the impact on source water, impact from concentration, issues with desalinated water products, and impact from gas emissions. The EIA also proposes measures to mitigate environmental impacts.
