“…Over the following two years, the biogas residue fractions tested had no statistical differences with the chemical and combinatorial treatments, something that could be ascribed to the residual N effect, observed also in other studies evaluating the nitrogen fertilizer replacement value of biogas residues (Cavalli et al, 2016) and manure (Schröder, 2005). This outcome suggests that the low degradation rate of organic N contained in BRs has the potential to gradually supply the soil with nutrients required for plant growth, particularly plants with a constant nitrogen demand, such as perennial forage grasses (De Boer, 2017). It should be noted that in our experiment, fertilization was done by hand and the fertilizers were applied to the soil surface rather than incorporated into the soil to reduce nitrogen losses through ammonia volatilization.…”

To provide sufficient quantities of food and feed, farming systems have to overcome limiting factors such as the nutrient depletion of arable soils. Nitrogen being the main mineral element required for plant growth, has led to the extensive use of chemical fertilizers causing nitrogen pollution of the ecosystems. This field study investigates the use of biogas residues (BRs) as biofertilizers and their contribution to the mitigation of nitrate leaching in agricultural soils, while also demonstrating the polluting nature of chemical fertilizers. Nine different fertilization treatments classified in three schemes and two nitrogen doses were tested for three consecutive years on a grassland in the Walloon Region of Belgium. Residual soil mineral nitrogen, percentage contribution of treatments in residual nitrate and agronomic performance were assessed for each fertilization treatment. The results obtained showed significant differences on treatment and scheme level regarding nitrate accumulation in the soil, with chemical fertilizers posing the highest nitrate leaching risk. BRs did not cause nitrate accumulation in the soil, and were N rate and rainfall independent, while the chemical treatments indicated a cumulative tendency under high N rate and low precipitation. Forage yield did not demonstrate statistical differences on treatment and scheme level but varied with changing precipitation, while the maximum application rate suggested a

“…The NO 3 fertilizers appeared to be more sensitive to the leaching, especially in sandy soils [27] and also to the denitri cation [28] as compared to urea or ammonium fertilizers. Also, NO 3 leaching is substantially higher in free-drained soils [29] , such as sandy soil with macropores used in the present study.…”

Nitrate (NO3) leaching from soils results in lower soil fertility, reduced crop productivity and groundwater pollution. The present study determined NO3 leaching from bentonite [0, 2 and 4% (m/m)] treated sandy soil, under three N sources (calcium nitrate [Ca(NO3)2], ammonium chloride [NH4Cl], urea [CO(NH2)2] @ 300 kg N ha-1) with a leaching fraction of 0.3-0.4. Bentonite markedly reduced NO3 release in leachate, while 4% bentonite retained higher NO3 in soil. The NO3 leaching varied with N sources as Ca(NO3)2>NH4Cl>(CO(NH2)2. This study indicated that soil amendment with bentonite could efficiently mitigate NO3 leaching from soil and hence prevent N fertilizer losses and groundwater pollution.

“…In the present study, the SD nitrogen application was between 350 and 500 kg N ha −1 , which was the highest among the studied treatments. Thus, we speculate that not all the N was in a mobile or crop-available form; thus, the SD nitrogen might have contributed to the soil organic matter on the one hand [20] and represents a constant source of available nutrients for the following crops [51] on the other.…”

Agro-Environmental Sustainability of Anaerobic Digestate Fractions in Intensive Cropping Systems: Insights Regarding the Nitrogen Use Efficiency and Crop Performance

Digestate is an anaerobic digestion by-product rich in inorganic-nitrogen (N) that can be used as an organic fertilizer. Digestate agronomic efficiency and its impact on the environment have not yet been studied in detail, therefore this study tries to fill this gap. The agro-environmental sustainability of digestate fractions was evaluated in a holistic way by comparing the best management practices available in the Veneto Region agroecosystem. A farm experiment involving mineral fertilizer and both liquid and solid digestate fractions was established involving silage winter wheat and silage maize as main crops. Agro-environmental sustainability was investigated coupling crop performance analysis (e.g., yield, N uptake and N use efficiency (NUE)) with a novel proposed agro-environmental sustainability index (AESI) (i.e., product of the dry yield and NUE). The results showed that the liquid digestate fraction gave agronomic performances comparable to mineral fertilizers and a satisfying AESI while solid digestate showed lower performances. In conclusion, liquid digestate fractions might be an effective substitute for mineral fertilizers in the Veneto region agroecosystem reaching encouraging levels of agro-environmental sustainability. On the contrary, longer-term experiments are requested to evaluate solid digestate fraction sustainability.
