“…The results show non-significant differences versus treatments for the zinc presence at a p-value of 0.123. Similarly, the average levels of zinc in the treatments indicated that the biosolid treatments minimized the presence of zinc in soil leachates, which is also pointed out by many studies due to the high amount of organic matter contained in biosolids [51]. Although zinc is an insoluble metal in water, its reaction with other components can create compounds, which possess solubility and can threaten groundwater when leached by water [52].…”

“…The reasons behind their absence can be easily recognized: the pelletized formula and the catching of heavy metals work synergistically to optimize the level of pollutants. Similarly, the literature also revealed that sandy soil's texture acts as another screen that filtrates the heavy metals via firmly binding them with the soil particles [51]. It worth mentioning that the levels of mercury, lead, tin and cadmium were scarcely below the detected levels in the leachates, as indicated from the chemical analysis of soil leachates and interpretation of the results.…”

This study was conducted to evaluate the effect of three different rates of municipal biosolids produced in Qatar on plant characteristics and soil texture and its potential impacts on groundwater. Petunia atkinsiana, was used in this study. The experiment took place in a greenhouse in pots with soil mixed with 0, 3, 5, and 7 kg/m2 biosolids. Pelletized class A biosolids from the Doha North Sewage Treatment Plant were used. Results revealed significant differences in all measured parameters, which were affected by biosolid treatments compared to the control treatment. Electrical conductivity, pH, macro and micronutrients and heavy metals were significantly affected by biosolid treatments. The comparison of the discovered levels against the international acceptable ceilings of pollutants indicated the advantages of utilizing class A biosolids, as they were well below the international acceptable levels and showed the best test rates, indicating that the product is a sustainable and efficient organic fertilizer for ornamental plants. Furthermore, the results highlight no potential significant impacts on groundwater due to trace presence of heavy metals, owing to the nature of deep groundwater in Qatar and the usage of modern irrigation devices that fulfil the exact needs of plants in a harsh climate and high evaporation rate.

“…In many irrigated orchard crops, OMA sources have been shown to increase soil C storage (Bittenbender et al, 1998; Canali et al, 2004; Neilsen et al, 2014; Sanchez et al, 2003). Many different OMA sources are also capable of increasing soil extractable P (Neilsen et al, 2014; Preusch & Tworkoski, 2003) and K (Baldi et al, 2010; Bittenbender et al, 1998; Gülser et al, 2015) as well as improving cation exchange capacity (Cayuela et al, 2004; Arvanitoyannis & Kassaveti, 2007; Amiri & Fallahi, 2009; Miller et al, 2013; Villa et al, 2021) without increasing the risk of soil pollution from heavy metals (Baldi et al, 2021). Despite these studies, understanding P and K availability in relation to OMA use is necessary given the potential effects by phosphatase activity (Neilsen et al, 2014), soluble factors of these nutrients (Brandt et al, 2004; Hammermeister et al, 2006) and surface application (Baitilwake et al, 2012; Corbeels et al, 2003; Jin et al, 2008).…”

Advancing conservation agriculture depends on understanding nutrient dynamics of organic matter amendments (OMA) on no‐till soil. This field incubation study compared surface‐applied composted dairy manure (CM), green waste compost (GWC) and an unamended control from March to September in 2015 and 2016 using a RCBD in a California almond (Prunus dulcis) orchard. Measurements included OMA nutrient release rates, changes in soil organic carbon (SOC), total N (TN) and inorganic N, P and K availability using in‐season soil sampling and collection of ion exchange resin (IER) membranes from 0 to 10 cm depth, and cumulative N and P availability using soil IER cores from 0 to 50 cm depth. We hypothesized OMA sources with a lower initial C:N increase soil N availability, greater soluble phosphorus (P) and potassium (K) concentrations increase P and K availability, and all OMA sources increase SOC with the greatest N recovery in the TN pool. No differences were observed in C, N and P release rates, while the K release rate was the greatest. In‐season N availability showed no effect but P and K availability differed as evidenced by greater IER adsorption and soil extractable P and K. Both OMA sources significantly increased in SOC and TN. Net N mineralization from OMA sources ranged from 0.7% to 8.0% of applied N and total N recovery in TN and inorganic N pools increased based on the initial C:N. These results advance our understanding of nutrient dynamics while conserving the soil due to the no‐till practice of surface‐applied OMA.

“…The long‐term experiments (LTEs) on integrated nutrient management (INM) provide opportunities to monitor the changes in soil physicochemical and biological properties over time in relation to various management practices, climatic conditions and sustainability of the cropping system benefitting many people in the society (Das et al, 2023; Maharjan et al, 2021). The integration of organic manures prepared from the available on‐farm crop residues and animal wastes in the cultivation practices is increasing worldwide due to its better fertilization effect and positive influence on the soil physical, chemical and biological properties (Baldi et al, 2021). The organic matter works as the energy substrate for the soil microbes, which encourages the biodegradation and bio‐mineralization processes eventually contributing the essential nutrients, including Fe to the plants (Fernández‐Calviño et al, 2018).…”

Wheat contributes to about one‐fifth of the total calories and protein consumption by humans but is found lower in total iron (Fe) concentration than the targeted nutritional requirement, leading to increasing cases of anaemia and malnutrition in humans, especially in the developing countries. Therefore, it is the need of the hour to understand the dynamics of Fe in soil and its supply in relation to wheat productivity and grain quality. The objectives of this study were to examine the impact of long‐term (54 years) annual and biannual application of different doses of farmyard manure (FYM) (0, 5, 10 and 15 Mg ha−1) and nitrogen (0, 60 and 120 kg ha−1) under integrated nutrient management on the dynamics of Fe in soil along with its relationship with total Fe uptake in wheat. Additionally, the release pattern of native soil Fe and risk of Fe toxicity were evaluated. The highest grain yield of wheat (6.08 Mg ha−1) was observed under biannual application of FYM and nitrogen at 10 Mg ha−1 and 120 kg ha−1, respectively, which was approximately 155% higher than the control plot (F0N0). Under the dual season application of 15 Mg ha−1 FYM and 120 kg ha−1 nitrogen, the total Fe content (48.48 mg kg−1) and its uptake (270.52 g ha−1) in wheat grains were found at maximum. The soil incubation study revealed that the rate of release of Fe increased up to 30 days of incubation followed by constant rates indicating the establishment of dynamic equilibrium among the different Fe fractions. Thus, the present study was conducted for the first time to improve the understanding of changes in Fe concentration and rate of release in soil, which directly influence the Fe uptake in wheat grain under the long‐term integrated nutrient management practices.
