Environmental issues are at the forefront of agricultural concerns throughout the United States and the world ( Malakoff, 1998 ; Nosengo, 2003 ). Nitrate N (NO 3 -N) and phosphorus (P) are two of the pollutants that have caught the public

With the increase of industrial and domestic sewage and agricultural fertilizers emissions, nitrogen (N), phosphorus (P), and other nutrients discharged into the lake are constantly increasing, making more and more lakes eutrophic ( Lian et al

Abstract

The purpose of this paper is to present a theoretical account of the phosphorus nutrition of plants in soils, including some of the evidence and thinking related to it. Because these remarks are directed to the “nutrient-solution fraternity,” a comparison of nutrient solutions and soils in respect of certain aspects of phosphorus nutrition may be an appropriate introduction.
