“…Mechanical chiselling has been used to mitigate compacted layers of soils under the NT system (Nunes et al, 2015). This practice usually benefits root development, increases soil porosity, mainly macroporosity, and decreases soil bulk density (Calonego & Rosolem, 2010;Nunes et al, 2014).…”

“…Thus, the use of grass species with vigorous roots, such as the polyculture of cover crops in this study, can improve the physical quality of compacted soils and benefit subsequent crops (Calonego & Rosolem, 2010). Furthermore, roots are a source of exudates and SOM, which stimulate aggregate formation and stabilization along the soil profile (Martins, Corá, Jorge, & Marcelo, 2009; Wendling, Jucksch, Mendonça, & Neves, 2005), especially in soils without mechanical disturbance (Ferreira et al, 2018; Nicoloso et al, 2018).…”

“…Mechanical (Calonego & Rosolem, 2010;Nunes et al, 2014;Nunes, Denardim, Pauletto, Faganello, & Pinto, 2015), chemical (Dalla Nora & Amado, 2013;Dalla Nora, Amado, Nicoloso, Mazuco, & Piccin, 2017;Hansel et al, 2017) and biological (Calonego et al, 2017;Colombi, Kirchgessner, Walter, & Keller, 2017;Cubilla, Reinert, Aita, & Reichert, 2002) interventions can alleviate soil compaction. Generally, mechanical interventions are more efficient for alleviating soil compaction in the short term (Calonego et al, 2017;Nicoloso et al, 2008), but in the medium and long term the effectiveness of mechanical interventions has been controversial (Calonego et al, 2017;Daigh et al, 2018;Nunes et al, 2014).…”

“…The root system of cover crops, single or intercropped, can alleviate compacted soil layers (Foloni, Lima, & Bull, 2006; Reichert et al, 2007; Williams & Weil, 2004). Cultivation of cover crops can improve soil surface protection against erosion and increase carbon allocation at surface and subsurface soil depths (Ferreira et al, 2018; Nicoloso, Rice, Amado, Costa, & Akley, 2018). Combination of phosphogypsum and lime has also been proposed as a strategy to alleviate subsoil acidity without the need for soil mechanical disturbance (Rosolem & Marcello, 1998; Shainberg et al, 1989; Sumner, 1995; Uusitalo et al, 2012; Walia & Dick, 2019) in North America and in Brazil (Caires, Alleoni, Cambri, & Barth, 2005; Caires, Barth, & Garbuio, 2006; Caires, Garbuio, Churka, Barth, & Corrêa, 2008; Dalla et al, 2014; Dalla Nora et al, 2017).…”

Soil compaction is one of the most relevant crop yield-limiting factors in no-till (NT) farming systems in southern Brazil. This study aimed to identify strategies to mitigate soil compaction and increase crop productivity at low, medium and high yield environments within a field. Treatments evaluated were: control (without intervention), PG (phosphogypsum), MC (mechanical chiselling), PCC (polyculture of cover crops), MC + PG, PCC + PG, MC + PCC and MC + PCC + PG. Soil physical and chemical attributes (soil macroporosity, bulk density, penetration resistance) and soybean yield (Glycine max L.) and black oat (Avena strigosa Schreb) biomass production were evaluated. In the low and medium yield environments, MC + PCC + PG promoted the highest soybean yields: 5,455 kg ha −1 and 5,534 kg ha −1 , respectively. In the high yield environment, PCC + PG promoted the highest soybean yield (5,579 kg ha −1), whereas MC decreased yields relative to the control. Black oat biomass production responded to the treatments similarly to soybean yields. Overall, integrating two or three decompaction strategies improved soil physical attributes in a greater proportion relative to single strategies and to the control, enhancing both soybean and black oat performances. Selection of the right decompaction strategies for each yield environment might help increase productivity under NT and optimize the use of time, labour, fuel and other resources. Highlights • Soil compaction limits crop yields under no-tillage farming in southern Brazil. • Low, medium and high yield environments were delineated with precision agriculture tools. • Single or integrated mechanical, chemical and biological soil decompaction strategies were tested. • Soil decompaction strategies to increase soybean yields are specific to yield environments.

“…Economically, NT is attractive because individual tillage events are eliminated, thus reducing machinery fuel, energy, and maintenance costs (Lal et al, 2007). No-till can also affect crop productivity (Daigh et al, 2018) and improve several soil properties, such as soil organic carbon (Nicoloso et al, 2018), soil aggregation (Fabrizzi et al, 2009), bulk density (Blanco-Canqui et al, 2009), and soil microbial community (Smith et al, 2016), thus improving soil health. Organic waste and organic fertilizer, such as cattle manure, may replenish and maintain soil nutrient equilibrium, thus increasing nutrient status and perhaps crop yield.…”

The objective of this study was to investigate the effect of different tillage systems and nitrogen (N) fertilizers on corn yield. Higher corn yields (207 bu/a and 203 bu/a) were found under no-tillage + high (150 lb N/a) manure application, and tillage + super high manure (750 lb N/a), respectively. The trend observed for the different nitrogen fertilizers between tillage systems was the same. However, a greater corn yield was observed under no-till in comparison to tilled conditions for both high fertilizer and high manure. No-till improves soil water infiltration, aggregation, nutrient cycling, and may increase crop yield. On other hand, soil erosion, runoff, and a depreciated plant stand may have been the reasons for lower yields under tillage for some of the treatments. Overall, the addition of organic fertilizer associated with no-till was a better practice for increasing corn yield compared to the use of mineral fertilizer associated with or without tillage.
