“…The availability of plant nutrients such as N, P or K is essential for plant growth (Haygarth et al, 2013;White and Greenwood, 2013). One of the advantages of wastewater irrigation is the supplying of nutrients that may be sufficient to replace, or at least to reduce, the use of synthetic fertilizers in agriculture (Adrover et al, 2012;Fatta-Kassinos et al, 2011;Toze, 2006).…”

The reuse of treated wastewater, in particular for irrigation, is an increasingly common practice, encouraged by governments and official entities worldwide. Irrigation with wastewater may have implications at two different levels: alter the physicochemical and microbiological properties of the soil and/or introduce and contribute to the accumulation of chemical and biological contaminants in soil. The first may affect soil productivity and fertility; the second may pose serious risks to the human and environmental health. The sustainable wastewater reuse in agriculture should prevent both types of effects, requiring a holistic and integrated risk assessment. In this article we critically review possible effects of irrigation with treated wastewater, with special emphasis on soil microbiota. The maintenance of a rich and diversified autochthonous soil microbiota and the use of treated wastewater with minimal levels of potential soil contaminants are proposed as sine qua non conditions to achieve a sustainable wastewater reuse for irrigation.

“…Many agronomic strategies can be adopted to increase the efficiency with which inorganic and organic fertilisers are used to provide the essential mineral elements required by crops . In principle, these optimise the chemistry, quantity, placement, and timing of fertiliser applications (Fageria et al 2011;Simpson et al 2011;Mueller et al 2012;Noack et al 2012;White et al 2012;White and Greenwood 2013). The chemical form and quantity of a mineral element required for crop production in a particular location depends critically on soil characteristics.…”

“…It operates over short distances, and is especially important for the macronutrients P and K that often limit crop production (Hinsinger et al 2011). The mass flow of a mineral element to the root surface is determined by its concentration in the soil solution and the transpiration-driven movement of water to the root surface (White and Greenwood 2013). It is important for the acquisition of essential mineral elements with large concentrations in the soil solution, such as N, K, S, Ca, Mg and Cl in agricultural soils, and for mineral elements that are required in relatively small quantities by plants, such as Fe, Mn, Zn, Cu, Ni, B and Mo (White et al 2013a).…”

“…Diffusion of mineral elements is determined by the concentration gradients between the root surface and the soil solution (White and Greenwood 2013), which are often dictated by interactions with soil mineral surfaces. It operates over short distances, and is especially important for the macronutrients P and K that often limit crop production (Hinsinger et al 2011).…”

The use of foliar fertilisers is not novel, and has been common practice in agriculture and horticulture for many decades (Fageria et al 2009;Kannan 2010;Fernández et al 2013).…”

Background Crops require adequate nutrition for the production of food, fibre and fuel, but soil conditions often limit the ability of crops to acquire mineral nutrients. To address this, mineral nutrients can be applied as inorganic or organic fertilisers to the soil or as liquid fertilisers to foliage. However, production and use of fertilisers can have negative environmental impacts. The articles in this Special Issue illustrate a number of ways to improve nutrient acquisition from the soil and their delivery through foliar application. Scope Articles highlighted here include those that discuss ways by which to assess a crop's requirement for additional mineral elements, ways by which minerals can be supplied more effectively to crops both through roots and shoots, and ways by which the crop itself can be enhanced to acquire more mineral elements. Conclusions It is apparent from the information contained in this Special Issue that to improve the ability of crops to acquire mineral elements, a number of strategies are available. However, the success of any one intervention is dependent on how these strategies interact with the environment in which they are deployed and the suitability of the management system for the specific intervention.
