“…Measurement of total soil nitrogen shows a large N loss during February to March 2005 of around 150 kg N ha −1 which is associated with higher rainfall during this summer period. This reduction is not associated with nitrate lixiviation or nitrogen uptake by the maize (Payet et al, 2009), and strongly suggests denitrification processes induced by microbial activity, which prefers very humid soil conditions, higher temperatures and soil rich in organic matter.…”

-In Réunion Island, expanding human populations, urbanization and agriculture during the last 50 years have all contributed to a steady increase in the level of nitrates in drinking water. Various nitrate point sources are responsible for the nitrate contamination around the island including chemical fertilizers, animal effluent applied to pasture and crops, and urban waste such as sewage and domestic waste water. In terms of agricultural fertilizers, pig effluent is the most widely used, but the cumulative effects of slurry applications on soil water and groundwater are unknown. Our objectives were (1) to characterize and follow in situ the fate of nitrogen through the subsurface after application of pig effluent onto a cultivated soil using stable nitrate isotopes, δ 15 N and δ 18 O, and (2) to compare the isotopic signatures of Réunion Island's principal aquifers with results from the experimental site to infer potential contamination sources. The study was conducted on an experimental field site planted with maize in the western part of Réunion Island during the rainy season. A control site with no fertilizer application to the maize was compared with the investigation site which had pig effluent applied once a year. The site which had pig effluent applied over one year had an average maximum surface soil water 15 N-NO − 3 value of +9.0% at 0.45 m depth. This signature was significantly more enriched in 15 N than the corresponding subsurface soil water 15 N-NO − 3 value of +3.8% at 10 m depth. The control site average maximum surface soil water 15 N-NO − 3 value of +3.6% at 0.45 m is similar to the subsurface pig effluent application plot. This indicates that nitrates derived from pig effluent have not reached 10 m depth in the subsurface, even though over the last 18 months this site was subjected to two effluent applications, each around 200 kg N ha −1 , and more than 1900 mm of rain, more than half of which drains directly into the root zone. This slow migration shows that mobilization of nitrates through cultivated soil can take many tens of years before infiltrating and contaminating the saturated zone situated at several tens, and in places, hundreds of meters depth. On an island-wide scale, an isotopic assessment of nitrates from the experimental site's soil water and other drinking water wells highlights a nitrogenous contamination derived primarily from urban and/or agriculture via effluent application.nitrates / nitrogen and oxygen isotopes / pig effluent / groundwater contamination / tropical island

“…A possible explanation may be related to ammonium adsorption to surface charges on the soil colloids, both in clays and organic matter, thus turning from the liquid to the solid phase. In addition, there is also a fast transformation of NH + 4 -N into nitrate (NO − 3 -N), regarding the nitrification process in an oxidizing environment (Payet et al, 2009;Zhang et al, 2011), which is conditioned by high drainage and aeration of Latossolo Vermelho Distroférrico (Typic Hapludox). According to Aita et al (2007), the entire amount of NH + 4 -N in the pig slurry (PS) can be nitrified within ten days after application.…”

“…Most of the N content in PS is in the form of ammonium (NH + 4 ) (Schirmann et al, 2013) and as applications are made on the soil surface, part is lost in the form of ammonia and another part is rapidly transformed into nitrate (NO − 3 ). Nitrate is mobile in the soil (Payet et al, 2009;Tuli et al, 2009), which favors N leaching. However, despite the low mobility of P in the soil, successive applications of mineral and mostly organic fertilizers increase the concentrations of organic and inorganic P in the solution, which favors its movement along the soil profile (Heathwaite, 2000;Fernandes et al, 2015).…”

Nutrient content in soil solution may vary in response to the applied amount of pig slurry (PS). Thus, the aim of this research was to evaluate the nutrient content in soil solution and its relationship to nutritional status and yield of corn under 12 years of annual fertilization with increasing doses of PS, soluble mineral fertilizer (MF) and PS combined with MF. The experiment was conducted under field conditions in a Latossolo Vermelho Distroférrico (Typic Hapludox). The treatments consisted of pig slurry at annual rates of 50 and 100 m 3 ha -1 (PS50 and PS100), soluble mineral fertilizer (MF), and pig slurry at a rate of 25 m 3 ha -1 complemented with mineral fertilizer (PS25 + MF), distributed in a randomized block design. Soil solution was sampled at two depths, 0.40 and 0.80 m, on six dates after the fertilizer applications. The nitrate (NO − 3 -N) and K levels in the soil solution were measured 40, 108 and 135 days after the last application of fertilizer (DAAF), being subsequently correlated with corn yield.

Successive swine effluent applications can substantially increase the transfer of phosphorus (P) forms in runoff. The aim of this study was to evaluate P accumulation in the soil and transfer of P forms in surface runoff from a Hapludalf soil under no-tillage subjected to successive swine effluent applications. This research was carried out in the Agricultural Engineering Department of the Federal University of Santa Maria, Brazil, from 2004 to 2007, on a Typic Hapludalf soil. Swine effluent rates of 0, 20, 40, and 80 m3 ha(-1) were broadcast over the soil surface prior to sowing of different species in a crop rotation. Soil samples were collected in stratified layers, and the levels of available P were determined. Samples of water runoff from the soil surface were collected throughout the period, and the available, soluble, particulate, and total P were measured. Successive swine effluent applications led to increases in P availability, especially in the soil surface, and P migration through the soil profile. Transfer of P forms was closely associated with runoff, which is directly related to rainfall volume. Swine effluent applications also reduced surface runoff. These results show that in areas with successive swine effluent applications, practices that promote higher water infiltration into the soil are required, e.g., crop rotation and no-tillage system.
