“…Therefore, in relation to the above, it is necessary to take actions to reduce the concentration of nitrate in groundwater and surface waters in arable lands as well as to monitor the N cycle in the soil and aquifer in order to assess the impact of fertilization on the quality of the soil–water environment, and consequently on human health [ 12 , 13 , 14 ].…”

The soil and human health issues are closely linked. Properly managed nitrogen (N) does not endanger human health and increases crop production, nevertheless when overused and uncontrolled, can contribute to side effects. This research was intended to highlight that there is a need for carrying out monitoring studies in agricultural areas in order to expand the available knowledge on the content of N forms in agricultural lands and proper management in farming practice. The impact of two types of fertilization, concerning spatially variable (VRA) and uniform (UNI) N dose, on the distribution of N forms in soils was analyzed. The analysis was performed on the basis of soil monitoring data from agricultural fields located in three different experimental sites in Poland. The analyses performed at selected sites were supported by statistical evaluation and recognition of spatial diversification of N forms in soil. It was revealed that the movement of unused N forms to deeper parts of the soil, and therefore to the groundwater system, is more limited due to VRA fertilization. Finally, it was also concluded that the management in agricultural practice should be based on the prediction of spatial variability of soil properties that allow to ensure proper application of N fertilizers, resulting in the reduction of possible N losses.

“…In this study, sewage did not stagnate in the infiltration bed and there was no odour coming from the infiltration bed. Also in highly-permeable soil beds with a supportive layer made of dolomite (Kalenik and Cieśluk, 2009), chalcedonite (Kalenik and Wancerz, 2013), clinoptilolite (Kalenik, 2014a;Kalenik and Chalecki, 2019), and hydro-anthracite (Kalenik, 2019) the effectiveness of TSS retention was high and equalled 98.2% and 99.1% for dolomite, 94% for chalcedonite, 81.9% and 85.4% (2014a) and 72.5% and 75.8% (2019) for clinoptilolite, 77.1% and 80.2% for hydro-anthracite.…”

“…Thus, the use of the supportive small coal layer significantly increased the total nitrogen removal effectiveness from sewage. Also in highly-permeable soil beds with a supportive layer made of dolomite (Kalenik and Cieśluk, 2009), chalcedonite (Kalenik and Wancerz, 2013), clinoptilolite (Kalenik, 2014a;Kalenik and Chalecki, 2019), hydro-anthracite (Kalenik, 2019) the effectiveness of total nitrogen removal from sewage increased significantly and equalled 35% and 44% for dolomite, 66.8% for chalcedonite, 29.5% and 37.3% (2014a) and 26% and 55.3% (2019) for clinoptilolite, 28.4% and 57.8% for hydro-anthracite. The effectiveness of ammonium nitrogen removal in the bed with the small coal layer with a thickness of 0.10 m equalled 87.8%, and the nitrate nitrogen content in treated sewage increased 10-fold on average.…”

“…In the bed with the medium sand layer alone the effectiveness of ammonium nitrogen removal was also high and equalled for 99% (Kalenik and Wancerz, 2013) on average. Also in highly-permeable soil beds with a supportive layer made of dolomite (Kalenik and Cieśluk, 2009), chalcedonite (Kalenik and Wancerz, 2013), clinoptilolite (Kalenik, 2014a;Kalenik and Chalecki, 2019) and hydro-anthracite (Kalenik, 2019) the effectiveness of ammonium nitrogen removal was high and equalled 98.2% and 99.1% for dolomite, 94% for chalcedonite, 81.9% and 85.4% (2014a) and 72.5% and 75.8% (2019) for clinoptilolite, 77.1% and 80.2% for hydro-anthracite. Also, Wąsik and Chmielowski's (2017) research confirm high effectiveness of ammonium nitrogen removal in highly-permeable beds, and it equalled 66.74%.…”

“…In order to improve the effectiveness of sewage purification in a highly-permeable soil bed, a research was conducted on application of following supportive layers: dolomite (Kalenik and Cieśluk, 2009), chalcedonite (Kalenik and Wancerz, 2013), clinoptilolite (Kalenik, 2014a;Kalenik and Chalecki, 2019), kermesite and gaize (Dacewicz, 2018), hydro-anthracite (Kalenik, 2019). On the other hand, there is no research regarding the use of small coal for treating sewage in soil beds in scientific and technical literature.…”

Aim of the studyThe aim of the study was to laboratory determine whether introducing a supportive small coal layer with a granulation of 0.02-5 mm will improve the effectiveness of removal of nitrogen and phosphorus compounds from domestic sewage. The study concerned a layer that improves effectiveness of domestic sewage treatment in a household sewage treatment plant under an infiltration drainage system. Material and methodsSewage treatment model study was conducted in a medium sand bed with a supportive small coal layer with a thickness of 0.10 and 0.2 m. Total suspended solids (TSS) were determined with a gravimetric method, BOD 5 with an electrochemical method, COD with a titration method with potassium dichromate, ammonium nitrogen, nitrite nitrogen, nitrate nitrogen, total nitrogen and total phosphorus were determined using colorimetric methods, and the reaction with an electrometric method. Results and conclusionsIt was observed that in terms of basic quality parameters (TSS, BOD 5 , COD, total nitrogen, total phosphorus) the effectiveness of sewage treatment was compliant with Polish guidelines for sewage disposal into ground and groundwaters. It was determined that a soil bed consisting of medium sand with a supportive layer of small coal with a thickness of 0.20 m is more effective in sewage treatment in comparison to a supportive layer with a thickness of 0.10 m. Application of the supportive layer of small coal with a thickness of 0.2 m in the medium sand soil bed improved the removal effectiveness of TSS by an average 19.8%, of BOD 5 by 1.1%, of COD by 4.7%, of total nitrogen by 24.7%, of ammonium nitrogen by 7.1% and of total phosphorus by 30.6% in comparison to the supportive layer with a thickness of 0.10 m. The study confirmed that small coal with granulation of 0.02-5 mm can be used to support removal of nitrogen and phosphorus compounds from sewage with an infiltration drainage system.

The objective of this experimental study was to examine whether an assisting layer of lightweight expanded clay aggregate (LECA) of the granulation 1-4 mm, introduced into a subsoil, is able to improve an efficiency of removal of total nitrogen and total phosphorus from domestic wastewater. In the investigations, an assisting 0.10 and 0.20 m thick LECA layer was applied. It has been observed that the effectiveness of removal of total suspended solids (TSS), total nitrogen and total phosphorus from wastewater as well as the level of biochemical oxygen demand (BOD 5 ) and chemical oxygen demand (COD) is in accordance with the Polish standards on wastewater disposal into grounds and surface water. The performed experiments showed that the effectiveness of raw wastewater purification for the medium sand soil bed with the 0.20 m thick assisting LECA layer is higher than for the 0.10 m thick assisting layer. In the medium sand soil bed with the 0.20 m thick assisting LECA layer, the removal efficiency regarding total nitrogen increased by 20.6%, total phosphorus by 5.2%, ammonium nitrogen by 8.8% and TSS by 5.3%, and reduction efficiency regarding BOD 5 increased by 1.7% and COD by 2.3% with relation to the 0.10 m thick assisting LECA layer (all percentages -in average). The results of the experiment showed that the LECA with the granulation 1-4 mm can be used to assist in removal of total nitrogen and total phosphorus from wastewater with application of infiltration drainage.
