Agricultural wastes from plant and animal operations are often land applied to recycle and manage residues. Compositional variability among these wastes is vast. Some waste components can potentially represent a threat to the environment and humans d

Abstract Off‐site transport of excess soil P from repeated P fertilizer applications constitutes waste of a vital resource and poses an environmental risk. Excess P can be mined by growing crops without P addition until it is exhausted to the point

Interest in the use of biochar in agriculture has increased exponentially during the past decade. Biochar, when applied to soils is reported to enhance soil carbon sequestration and provide other soil productivity benefits such as reduction of bulk d

We hypothesized that, because of the ability of trees to sequester carbon (C) in the deep soil profile and remove excess nutrients from soils, the silvopastoral agroforestry system could enhance the environmental quality of the agricultural lands. To

The risk of phosphorus loss from agricultural soils can have serious implications for water quality. This problem has been noted particularly in sandy soils in several parts of the world including Europe (e.g., the Netherlands, Italy, and UK) and the

Reliable techniques must be developed to predict phosphorus (P) storage and release from soils of uplands, ditches, streams, and wetlands in order to better understand the natural, anthropogenic, and legacy sources of P and their impact on water qual

This 7-page fact sheet uses a new procedure to evaluate the soil from active and abandoned dairies in the Lake Okeechobee watershed to determine their potential to negatively impact water quality through phosphorus release. Written by V.D. Nair, M. C

One of the factors that determines whether a source of phosphorus will have a negative impact on water quality is solubility. This 3-page fact sheet discusses the significantly different solubility of commonly found phosphorus sources in Florida. Wri

Under what conditions can plants be used to remove phosphorus from common Florida soils? This 5-page fact sheet shows how calculations for the phosphorus saturation ratio and soil phosphorus storage capacity at various soil depths can be used to dete
