“…However, tillage has become a controversial practice over the last few decades. For example, better plant growth/performance and improved soil physicochemical properties were achieved with DT (Patil and Sheelavantar, 2006; Somerville et al, 2018) or CT (Yagioka et al, 2015) or MT (Muhammad et al, 2018; Wolff et al, 2018). Beside tillage operations, fertilization is considered as one of major agronomic practices in the farming system of the studied areas.…”

“…Returning organic residue to the soil and N fertilization can increase SOC (Khan et al, 2018) and TN both in tilled and non‐tilled systems (Somerville et al, 2018). The small farmers keep their cattle at home and/or farm and thus the available farmyard manure (FYM) from these cattle would be a useful source of readily available nutrients at the farm level (Khan et al, 2017; Muhammad et al, 2018).…”

Increasing soil organic matter (SOM) contents improve the resilience of productive soil for future sustainability particularly in poor soil (<1% SOM). This study sought to elucidate how tillage and N fertilizer sources affect soil bulk density, soil organic carbon (SOC) and soil total N (TN) in 0‐ to 20‐cm soil depth. Treatments included minimum till (MT), conventional till (CT), deep till (DT), and twelve N treatments (60 and 120 kg urea N ha−1, 10 and 20 Mg farmyard manure [FYM] ha−1, 10 Mg soybean residue [SR] ha−1 and their combinations along with a control). The experiment was designed in randomized complete block design with split plot arrangement. Soil bulk density increased for DT toward the end of the experiment than CT or MT. The sequestration rates of SOC of MT was 22% higher than DT. The FYM retuned more SOC than SR, however SR returned more TN than FYM. Application of FYM as well as SR sequestered more C than urea or control. Conclusively, SOC returned was increased with 10 Mg FYM ha−1 along with 30 kg urea N ha−1 but TN with 10 Mg SR ha−1 in CT plots. This practice can therefore increase soil quality and productivity, and thus is considered a sustainable approach for soils deficient in organic matter. Core Ideas Minimum tillage improved C stock than shallow or deep tillage. The addition of urea increased SOC contents in SR plots than FYM. C Stocks in FYM and SR fertilized plots was about 3‐ to 4‐fold greater than control. Soybean residue build N stock principally in less plowed plots.

“…Additionally, the incorporation of 540 Mg/ha of compost 50 cm deep in the soil profile in four soils with different parent materials reduced the bulk densities by 19-21% compared with the control [118]. Somerville et al [119] studied the effect of sludge compost application (50% v/v) on three different soil types (two different loamy coarse sands and a coarse sandy loam). The bulk density decreased in all three soils at a rate of 15-26% and 14-25% after 3 and 15 months of application.…”

Recycling of Organic Wastes through Composting: Process Performance and Compost Application in Agriculture

et al. 2020

Composting has become a preferable option to treat organic wastes to obtain a final stable sanitized product that can be used as an organic amendment. From home composting to big municipal waste treatment plants, composting is one of the few technologies that can be practically implemented at any scale. This review explores some of the essential issues in the field of composting/compost research: on one hand, the main parameters related to composting performance are compiled, with especial emphasis on the maturity and stability of compost; on the other hand, the main rules of applying compost on crops and other applications are explored in detail, including all the effects that compost can have on agricultural land. Especial attention is paid to aspects such as the improvement of the fertility of soils once compost is applied, the suppressor effect of compost and some negative experiences of massive compost application.

“…The less intense air flow causes reductive conditions that may promote the formation of toxic forms of substances and alters nutrients availability [113]. Compacted urban soils are often remediated with the addition of compost, biochar, or tillage practices [101,114,115]. However, it is preferable to prevent compaction through appropriate design of the Technosols, for example using crushed concrete in soil mixture.…”

Constructed Technosols: A Strategy toward a Circular Economy

et al. 2021

Soil is a non-renewable natural resource. However, the current rates of soil usage and degradation have led to a loss of soil for agriculture, habitats, biodiversity, and to ecosystems problems. Urban and former industrial areas suffer particularly of these problems, and compensation measures to restore environmental quality include the renaturation of dismissed areas, de-sealing of surfaces, or the building of green infrastructures. In this framework, the development of methodologies for the creation of soils designed to mimic natural soil and suitable for vegetation growth, known as constructed soils or technosols, are here reviewed. The possible design choices and the starting materials have been described, using a circular economy approach, i.e., preferring non-contaminated wastes to non-renewable resources. Technosols appear to be a good solution to the problems of land degradation and urban green if using recycled wastes or by-products, as they can be an alternative to the remediation of contaminated sites and to importing fertile agricultural soil. Nevertheless, waste use requires analysis to ensure the salubrity of the starting materials. Moreover, materials produced on site or nearby minimize the cost and the environmental impact of transport, thus the involvement of local stakeholders in the urban land management must be encouraged.
