In-situ comparison of phosphorus losses between organic and inorganic fertilizersPhosphorus (P) is one of the limiting factors of eutrophication. P added to soil from fertilizer application could pose a threat to water quality. According to agricultural habits, swine manure (SM), oil cake (OC), biogas slurry (BS), commercial organic fertilizer (OF) and compound fertilizer (CF) were selected to compare their P losses on a slope-land under natural rainfall. The results showed ...

Sugarcane response to mill mud, fertilizer, and soybean nutrient sources on a sandy soil
Improving soil organic matter and soil fertility are important factors in the sustainability of sugarcane (Saccharum spp.) production. A 3-yr field trial was established in 2004 on a sandy Alfisol in Florida to compare the effect of organic and inorganic nutrient sources on sugarcane production. The three nutrient sources were (i) mill mud (filter cake, cachaza), (ii) local standard fertilizer, ...

Estimating Phosphorus loss in runoff from manure and fertilizer for a Phosphorus loss quantification tool
Nonpoint-source pollution of fresh waters by P is a concern because it contributes to accelerated eutrophication. Given the state of the science concerning agricultural P transport, a simple tool to quantify annual, field-scale P loss is a realistic goal. We developed new methods to predict annual dissolved P loss in runoff from surface-applied manures and fertilizers and validated the methods ...
