Also, the utilization of
MAP as fertilizer would help to reduce the application of
rock phosphate in the agricultural sector. Thus, MAP could
help to create an eco-friendly environment by reducing the
need for rock phosphate. According to our previous study
(Rahman et al., 2011) and Bashan and Bashan (2004), MAP
may have a low leaching rate and slowly release nutrients
during the plant-growing season. In this study, the
efficiency of MAP recovered from swine wastewater as a
sustainable fertilizer was tested by investigating the
influence of MAP on the growth, biomass yield, nutrient
content, chemical composition and energy content of maize
fodder and further by calculating N2O emission under the
maize growth.
