“…Thus, for several reasons, it is increasingly important to reduce dependence on chemical fertilizers to restore soil fertility. On this topic, domestic and agro-industrial activities generate waste of high fertilizing value, which can contribute to reduce the dependence on inorganic fertilizers [12,13].…”

Strategies for waste valorisation from domestic and agro-industrial activities must be pursued, and its use as a soil amendment is an interesting possibility. In this four-year study, the effect of applying municipal solid waste (MSW), farmyard manure (FYM), bottom wood ash supplemented with nitrogen (Ash + N), the inorganic fertilization common in the region (50 kg ha−1 N, P2O5 and K2O) (Control) and this inorganic fertilization supplemented with 70 kg N ha−1 (High N) was assessed in a rainfed olive grove planted in a shallow soil with low organic matter and managed with conventional tillage. The High N treatment significantly increased olive yield in comparison to the other treatments (165% more than MSW), and soil available N proved to be the main driver for tree productivity. MSW and FYM increased soil organic matter, as well as the levels of phosphorus and cation exchange capacity, leaving good indications for future production cycles, although during the four years of the study these treatments provided little N to the trees. The High N treatment significantly reduced soil organic matter (63% less than MSW). The result was attributed in part to the soil management system that did not allow the development of herbaceous vegetation, but also to an effect known as “added N interaction”, in which the excess of inorganic N in the soil might have contributed to accelerate the mineralization of native soil organic matter, an aspect that compromises the sustainability of this fertilization strategy. Although MSW and wood ash are sometimes associated with risks of environmental contamination with heavy metals, in this study the levels of heavy metals in soils and in plant tissues were not of concern.

Salinity and sodicity problems are ubiquitous in dryland and irrigated systems, and research into possible amendments to remediate soils in these systems is needed. This study was conducted to investigate the effects of organic and inorganic amendments on spring wheat (Triticum aestivum UG99) yield and salts redistribution within the profile of a repacked saline-sodic silt loam soil (EC e = 12.9 dS m −1 , exchangeable sodium percent (ESP) = 17.6% for control). The experimental design for greenhouse study was completely random with two factors (amendment and leaching fraction, LF). The amendments included biochar (2%) [B], biochar + manure (2%) [BM], zeolite modified with CaCl 2 (2%) [ZC], super absorbent (1%) [SA], and a control (no amendment) considering two levels of LF (15 and 30%). All amendments, except ZC, decreased soil bulk density and electrical conductivity, and increased soil pH and water content at field capacity after 2 pore volumes leaching. There was positive effect (p < .001) of B, BM and SA on wheat ground cover and grain yield; ZC amendment had no effect on wheat growth or yield. The LF levels did not affect wheat growth or yield. The amendments (B, BM and SA) decreased Na + and Mg 2+ concentration in straw, while K + concentration increased; resulting in reductions in the Na + /K + ratio. In general, the study showed that B, BM and SA are suitable amendments for increasing yield by improving soil conditions and reducing salts and Na + accumulation in plants.

“…Today's urban societies, however, generate a lot of waste with recycling potential, including organic waste. Unfortunately, in industrialized countries, a significant proportion of municipal solid waste (MSW) is sent for incineration or is landfilled (Murtaza et al, 2019;Rockwood et al, 2012). However, growing concerns about air quality and greenhouse gas emissions are increasing the interest in using agricultural soils as a means of MSW disposal (Weil & Brady, 2017).…”

“…Properly composted MSW can have a fertilizer value equivalent to farmyard manure. It can contribute to the introduction of organic carbon (C) into the soil and the recycling of other nutrients, promoting soil fertility and enhancing crop productivity (Grau et al, 2017;Leogrande et al, 2016;Murtaza et al, 2019). However, materials from undifferentiated collections of waste can present quality problems, the greatest of which is the risk of containing heavy metals (Deepesh et al, 2016;Liu et al, 2019).…”

Municipal solid waste compost (MSWC) is a source of organic C and other nutrients, which, when free from potential contaminants, can be used as a soil amendment. This study was carried out over three years in a vineyard with soil pH close to neutral under an experimental design consisting of two treatments (with and without MSWC). Application of MSWC is currently authorized under national legislation to be used in vineyards, orchards and forests at a maximum rate of 10 t ha −1 year −1 . In this study, for experimental purposes, a double rate (20 t ha −1 year −1 ) was used. The accumulated grape yield increased in the amended plot by 28% and the dry biomass of weeds between rows by 119%. The MSWC significantly increased some relevant soil properties such as organic C, pH, cation exchange capacity (CEC) and extractable P, K and B. The concentration of K increased significantly in several tissues, and the concentration of P decreased.However, the concentration of K, P and other essential nutrients in the leaves remained within their sufficiency ranges. Tissue levels of heavy metals (Cr, Cd, Pb and Ni) did not increase with the MSWC application, and the values in the pulp remained below the limits established for foodstuffs. The results from this study indicate that the continuous application of the MSWC does not seem to be sustainable, because of the risk of causing nutritional disorders. Products with similar composition should therefore be used only on more acidic soils and should never exceed the legally established rates.
