“…The stimulating effects of SS were attributed to increasing microbial activity and improving activity of the effective enzymes in nutrient transformation to available forms for plant, which could lead to increased nutrient absorption and plant growth (Pascual et al 2007). Similarly, Mohamed et al (2018) suggested that improved shoot yield of Moroccan sunflower may be attributed to potential source of N and P for plant in SS. According to the results, the positive correlations were obtained between the basil shoot and root nutrients concentrations and its growth characteristics.…”

“…The sewage sludge (SS), as one of the organic wastes produced by the wastewater treatment process, has been extensively spread on agricultural lands as a fertilizer (Dindar et al 2017). Land application of SS may have many beneficial effects on soil characteristics, for example, improving soil organic matter, reducing bulk density and increasing soil porosity (aeration), drainage, soil structure stability, soil water holding, and buffering capacity (Chu et al 2017), and enriching nitrogen, phosphorus, and micronutrients in soil, all of which present advantages for crop production (Mohamed et al 2018). In addition, due to presence of various hazardous components in SS such as heavy metals, organic compounds including pharmaceutical products, pathogens, and potential contamination risks for ecosystem components such as plant, soil, water, and fauna and consequently human health should be monitored intensively (Rathod et al 2009;Chu et al 2017).…”

Irradiation of sewage sludge (SS) with gamma-ray is regarded as a promising alternative and rapid method for risk mitigation of this waste in ecosystems. The effects of 13 treatments (15, 30, and 60 g kg −1 of non-irradiated SS and irradiated with doses of 5, 10, and 20 kGy gamma-ray and soil without SS and irradiation as the control treatment) was investigated on the growth, herbage yield, leaf chlorophyll index, and concentrations of macronutrients in basil (Ocimum basilicum L.) root and shoot in a completely randomized design with three replications under greenhouse conditions. The results showed that application of gamma-irradiated and non-irradiated SS positively affected the concentrations of nitrogen, phosphorus, potassium, sodium, calcium, and magnesium in basil shoot and root. The highest and lowest dry weights of root and shoot, plant height, leaf area, and leaf chlorophyll index were observed in 30 g kg −1 SS irradiated with 20 kGy absorbed dose and 60 g kg −1 non-irradiated SS, respectively. In ≤ 30 g kg −1 SS, the gamma irradiation absorbed dose did not significantly change the growth parameters, thus the use of ≤ 5 kGy absorbed dose may be suggested to stimulate positive effects on basil growth. Also, in 60 g kg −1 SS, the restrictive effects were mitigated by increasing the absorbed dose, but the use of ≥ 5 kGy absorbed dose may not cost-effective. Therefore, in order to improve nutrition and growth of basil plant, application of ≤ 30 g sewage sludge irradiated with 5 kGy absorbed dose of gammaray per kilogram soil can be suggested under similar conditions.

“…Furthermore, it was found that all the treatments irrigated with treated domestic effluent were statistically equal to the S1A1 system, and both were different from the conventional system with no fertiliser (S1A0) for the production indicators NPP, NGP and PROD. Agreeing with the results, Mohamed et al [37] considered that the application of treated domestic effluent altered the nutritional properties of the soil due to both the nutrient-richness of the organic residue itself and the nutrients readily available to be absorbed by the plants or made available through mineralisation. Galbiatti et al [36], growing common bean (Phaseolus vulgaris (L.)) under organic and mineral fertiliser, observed that treatments which received biofertiliser and the treatment with only one complete dose of mineral fertiliser were statistically equal and superior to the treatments with an interaction.…”

“…Bezerra et al [43], cultivating sunflower irrigated with treated domestic effluent and with different doses of nitrogen, found a significant increase in the productivity of plants that were irrigated with the treated domestic effluent. Mohamed et al [37] found that the production of sunflower grains was as satisfactory as in treatments with NPK mineral fertiliser.…”

Production Indicators in Cowpea as a Function of the Water–Fertiliser Nexus

The bean is an important crop in feeding the global population. In the northeast of Brazil, it is of particular importance, since it is a staple food, which also generates employment and income. The low productivity of the northeast in recent years due to the water crisis combined with the cost of energy has compromised technical and economic viability. This study aimed to evaluate production parameters of cowpea (Vigna unguiculata (L.) Walp.) under different alternative production systems in the northeast of Brazil. The study was carried out in the experimental area of the sewage treatment plant (STP) in the district of Tianguá, Ceará. The experiment comprised six production systems (treatments) divided into split plots distributed in a completely randomised design with fifteen replications. The systems irrigated with wastewater and amended with different of fertilisers were no fertiliser (S2A0), mineral fertiliser (S2A1) and organic fertiliser (S2A2), as well as systems irrigated with drinking (S1A0, S1A1 and S1A2). It was found that under the systems irrigated with wastewater, the average productivity was 1468.8 kg ha−1, whereas under the systems irrigated with drinking water, it was 984.1 kg ha−1. The production systems that used wastewater (S2A0, S2A1 and S2A2) resulted in greater productivity compared to the production models irrigated with drinking water with organic fertiliser (S1A2) and with no fertiliser (S1A0). All the production models irrigated with wastewater yielded similar results to the conventional system with mineral fertiliser, showing that treated wastewater contains sufficient nutrients to potentially replace mineral fertilisers in cowpea production in the northeast of Brazil. The use of treated domestic effluent increases the productivity of irrigated crops.

“…Sustainability requires organic waste to be managed as a valuable resource, rather than as a strain for the environment [2]. The most promising and appropriate way to properly manage and reuse wastes of industrial or agricultural origin is soil fertilization.…”

The effect of application of digestate and agro-food industry sludges on Dystric Cambisol porosity

et al. 2020

The spatial arrangement and pore size distribution play an important role in accumulation and protection of exogenous organic matter (EOM) in the soil, but how different organic materials contribute to modify pore structure is poorly understood. We aimed at exploring possible changes in the complexity of the soil phase during fertilization with different doses of digestate and sludges sourced from the agro-food industry. For this purpose, the shortterm effects-one year, of soil fertilization, were investigated in several sampling periods and within two depths (0-25 cm and 25-40 cm). Changes in the specific surface area (SSA), total pore volume (V MIP), total pore area (S MIP), average pore radius (R MIP) and pore size distribution (PSD) were monitored using N 2 adsorption/desorption (NAD) and mercury porosimetry (MIP) methods. Our results showed that the intensity of observed changes depended on the type and dose of organic material, soil depth and sampling date. Accumulation of EOM increased with soil depth, masking a large proportion of SSA. Deeper soil layer was more susceptible to changes in the pore size distributions due to the formation of new elongated pores. We concluded that this specific structural porosity was related to the decomposition of organic matter during the formation of soil aggregates.
