Florida citrus growers are well aware that nitrogen (N) is the single most important nutrient applied as a fertilizer to assure maximum yield and fruit quality. Most growers are probably also aware of the substantial N fertilizer price increases that have occurred during the past year (Table 1). Ammonium nitrate, the workhorse N fertilizer used by citrus growers for decades, has had the greatest leap in cost. Typical questions on the minds of growers these days are: why has this happened, will it continue, and will economics force a change in the type of N fertilizer we use?  This document is SL-238, one of a series of the Department of Soil and Water Sciences, UF/IFAS Extension.

Wetlands cover almost 30% of the state of Florida and account for just over 10% of the remaining wetland area in the lower 48 United States. Over the past 200 years Florida has lost an estimated 10 million acres of wetland, about half of the total area thought to exist in the 1780's. Some of these remaining wetlands are well known, like the Florida Everglades, while others may be small and unassuming. All play a vital role in flood protection, water quality and wildlife habitat. The Florida Wetlands Extension web site is designed to provide you with a better understanding of wetlands and wetland-related issues in Florida where these ecosystems are such a prominent feature. This document outlines some of the subjects covered in the site. his document is Fact Sheet SL217, one of a series of the Soil and Water Science Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

Abstract. Abstract: Over the past two decades, substantial reductions in the deposition of acidifying substances (primarily sulphur) have occurred in most parts of Europe and, following recent agreements, this trend is likely to continue. The question arises as to how have sensitive ecosystems reacted, and will react in the future, to these reduced inputs of acidity? In this paper, the SMART dynamic acidification model predicts the possible recovery of 36 acid-sensitive Finnish headwater lakes, for which both catchment soil and water quality measurements were available. The model was calibrated to measurements by adjusting poorly known parameters; it was then used to simulate soil and water chemistry until 2030 under the ‘current legislation scenario’ resulting from implementing current European emission reduction agreements. Whereas most of the catchment soils show very little change in base saturation, the positive trends in lake ANC and the negative trends in lake sulphate concentrations, observed over the past decade, continue into the future, albeit at a slower pace. The model predicts that, during 2010–30, all lakes will have reached a positive ANC, a pre-requisite for the recovery of fish populations.
