“…Substantial NO 3 –N leaching losses were measured in the late spring season, in concert with water percolation and fertilization timing. Our findings are similar to other Prairie studies that reported greater late spring subsurface N losses (Kokulan Macrae, Lobb, et al., 2019; Nikiéma et al., 2013; Singh et al., 2019). The largest late spring NO 3 –N leaching losses were observed in spring 2013 from all treatments.…”

“…Nutrient leaching has been a concern for parts of the Prairie regions that are dominated by coarse‐textured soils and situated over regional unconfined aquifers like the Assiniboine Delta Aquifer. Therefore, several studies have explored the impact of soil and management on subsurface nutrient leaching, including manure management (Kokulan et al., 2022; Nikiéma et al., 2013), fertilization (Karimi & Akinremi, 2018; Kokulan, Manimel Wadu, et al., 2021), animal grazing (Singh et al., 2019), cropping systems (Kokulan et al., 2022), and subsurface drainage (Kokulan, Macrae, Lobb, et al., 2019; Satchithanantham et al., 2014) in the Canadian Prairies. However, implementing conservation practices without considering seasonal climate could reduce their efficacy (Bergström et al., 2015).…”

Identifying seasons sensitive to nutrient losses could help farmers and policymakers to formulate effective nutrient loss reduction strategies. This long-term study monitored water percolation as well as nitrate (NO 3 -N) and total phosphorus (TP) leaching from liquid swine manure and chemical fertilizer applied to intact core lysimeters in a sandy loam soil in Manitoba, Canada. Water percolation, NO 3 -N, and TP leaching were monitored from 2005 to 2016. Chemical fertilizer showed greater average annual mean water percolation (p = .01), annual flow-weighted mean concentration (FWMC) of NO 3 -N (22 mg L -1 ; p < .001), and annual NO 3 -N leaching (36 kg N ha -1 ; p = .002) compared with the manure treatment (FWMC NO 3 -N, 15 mg L -1 ; NO 3 -N leaching load, 22 kg N ha -1 ). Average annual mean TP loss did not differ between treatments (p = .86). Spring (April-June) was the most sensitive season, when >75% of annual percolation, >80% of annual NO 3 -N, and >68% of annual TP leaching losses occurred from both manure and chemical fertilizer. Annual NO 3 -N and TP leaching increased exponentially with cumulative winter and spring precipitation (control, r 2 = .69; manure, r 2 = .79; chemical fertilizer, r 2 = .63) and decreased with winter and spring air temperatures. The largest spring NO 3 -N and TP leaching losses were observed in 2013, which followed the dry year of 2012, indicating the potential for nutrient flushing. The findings emphasize the need for environmentally sound N and P management strategies in cold North American regions underlain by coarse-textured soils, particularly during the spring season.

This study aimed to analyze the level of damage to the groundwater environment in terms of groundwater quality in the coastal area of Parangtritis and its surroundings. This research study unit is based on the landform unit and activities of the community. The research location is located in Parangtritis Village, Yogyakarta Special Region (DIY) Province. This study used a descriptive quantitative analysis as its method of analysis. This study used primary data obtained by testing groundwater samples in the laboratory. The groundwater sampling technique is carried out using the purposive sampling area. Groundwater sampling was carried out on eleven land units. The determination of the level of environmental damage to groundwater is carried out using the Pollution Index (IP) method referring to the Regulation of the Minister of Environment Number 115 of 2003. The results showed that the environmental damage to groundwater shows the quality status of lightly polluted water with pollutant index values ranging from 1.244-4.176 with variable pollutants chemical oxygen demand (COD), dissolved oxygen (DO), ammonia, nitrate, phosphate, and total coliform as well as with sources of pollutants from settlements, livestock, and agricultural activities.

“…For N, it should be considered that its main form of application is through nitrogen fertilization, which may generate spots with high N values (Li et al, 2018). This characteristic can lead to a reduction in productivity and the lixiviation of nitrate into underground waters, especially in soils with sandy texture (Singh et al, 2019).…”

The conversion of the native Cerrado into agricultural systems promotes a reduction in the input of organic residues on the soil, which can compromise the contents of soil organic carbon. The spatial distribution of carbon and nitrogen stocks in the soil is normally influenced by environmental and anthropogenic factors. This research aimed to map and evaluate the spatial variability of carbon and nitrogen stocks in the soil, in different integrated systems and pasture areas in the edaphoclimatic conditions of the Cerrado biome, in the state of Maranhão. The work was set up in a Red-Yellow Latosol with different management methods: crop-livestock integration with no-till farming, crop-livestock integration with patch scarification and harrowing, crop-livestock-forest integration, and pasture. The samples were removed at a depth of 0.0-0.20 m, in a grid with a regular interval of 50 m, totaling 193 points. The data were subjected to descriptive statistics, geostatistics, and kriging interpolation. The mean and median values are similar for the carbon and nitrogen stocks, in their respective management systems, indicating symmetric data distribution, confirmed by the asymmetry and kurtosis values close to zero. The spatial distribution of the carbon stocks is more homogeneous in the crop-livestock integration with no-till farming, whereas the crop-livestock integration with patch scarification and harrowing presents greater homogeneity in nitrogen distribution.
