“…According to Hontoria et al. (2018), the positive effect of NT on SOM variables increased with time. The beneficial effect of Ca‐amendment was stronger in the early years, and this combination may provide more stable crop yields.…”

“…As reported for lime, phosphogypsum application also stimulates microbial activity (Nahas, Delfino, & Assis, 1997) and, consequently, SOM decomposition. Nevertheless, in a long‐term approach, the negative impacts could be compensated for by lime and/or phosphogypsum applications due to soil fertility improvements and, consequently, greater C input by aboveground and belowground crop biomass (Briedis et al., 2012a; Hati et al., 2008; Hontoria et al., 2018; Inagaki, et al., 2017; Ridley et al., 1990) and soil microbial activity, indirectly driving the formation of aggregates (Bortoluzzi et al., 2010; Castro et al., 2011) and soil structure (Paradelo et al., 2015). No‐till management combined with liming increases SOC (Vazquez et al., 2019).…”

“…Lime application on the surface under NT is a prerequisite to enhance soil chemical fertility (da Costa & Crusciol, 2016;Inagaki, de Moraes Sá, Caires, & Gonçalves, 2017;Tiritan et al, 2016) and crop yield (Briedis, de Moraes Sá, Caires et al, 2012a). Combining liming with NT could increase the biomass inputs from crop residues and consequently SOC (Hontoria et al, 2018;Inagaki, de Moraes Sá, Caires, & Gonçalves, 2017); several beneficial impacts on soil physical attributes have been reported (Briedis et al, 2012a;Grant et al, 1992;Inagaki et al, 2017;Rowley et al, 2018). However, the dispersion and flocculation of colloids by liming changes the chemical soil solution and, in the short-term, could reduce the aggregation of soil particles (Castro & Logan, 1991;Chan & Heenan, 1999;Prado, 2003).…”

Lime and phosphogypsum applications are well‐established practices in weathered soils, and their surface application under no‐till (NT) can affect soil physical attributes and C and N fractions. This study determined the long‐term (10‐yr) effects of lime and phosphogypsum applications to the soil surface on soil C and N fractions of a tropical NT field. The experimental design was a randomized block with four treatments and four replications. The following treatments were applied in October 2002, November 2004, and October 2010, respectively: limestone (2,000 kg ha−1), phosphogypsum (2,100 kg ha−1), and limestone (2,000 kg ha−1) plus phosphogypsum (2,100 kg ha−1). In general, after 10 yr of liming, both alone and when associated with phosphogypsum, the cumulative crop straw inputs were increased at least 20% across the years, and the C fractions increased remarkably at different soil depths. Both treatments improved the SOC stocks by 24% (12.5–15.6 Mg ha−1) at 0.1–0.2‐m soil depths and by 10% (30.6–33.8 Mg ha−1) at 0–0.2‐m soil depths, and in general the soil aggregation at 0–0.4‐m soil depths. However, the particulate C and N fractions were reduced at 0–0.05‐m soil depth, suggesting a slight response to the transitory trend of soil organic C (SOC) depletion. Liming, both alone and when associated with phosphogypsum, overcame the transitory C pool depletion and improved soil aggregation, soil C fractions, and SOC stocks and could be considered an important factor that drives the sustainability of cropping systems under NT.

“…Many studies that are considered as long-term trials usually do not exceed 10 years [6,28,[37][38][39][40][41][42][43][44][45]. There are a few studies conducted over periods between 11 and 20 years [21,27,[46][47][48][49], and very few studies exceed 20 years [50][51][52].…”

Long-term field trials are essential for monitoring the effects of sustainable land management strategies for adaptation and mitigation to climate change. The influence of more than thirty years of different management is analyzed on extensive crops under three tillage systems, conventional tillage (CT), minimum tillage (MT), and no-tillage (NT), and with two crop rotations, monoculture winter-wheat (Triticum aestivum L.) and wheat-vetch (Triticum aestivum L.-Vicia sativa L.), widely present in the center of Spain. The soil under NT experienced the largest change in organic carbon (SOC) sequestration, macroaggregate stability, and bulk density. In the MT and NT treatments, SOC content was still increasing after 32 years, being 26.5 and 32.2 Mg ha−1, respectively, compared to 20.8 Mg ha−1 in CT. The SOC stratification (ratio of SOC at the topsoil/SOC at the layer underneath), an indicator of soil conservation, increased with decreasing tillage intensity (2.32, 1.36, and 1.01 for NT, MT, and CT respectively). Tillage intensity affected the majority of soil parameters, except the water stable aggregates, infiltration, and porosity. The NT treatment increased available water, but only in monocropping. More water was retained at the permanent wilting point in NT treatments, which can be a disadvantage in dry periods of these edaphoclimatic conditions.

“…In addition, the mulching effect of crop residues in soil surface can reduce the water evaporation especially under drought conditions (Vita et al, 2007). Both improved infiltration and reduced evaporation, increase water availability for crops, which is one of the main drivers of higher crop production with NT under Mediterranean or semiarid conditions (Bescansa et al 2006;Cantero-Martínez et al 2007;Vita 2016;Brunel-Saldias et al 2018;Hontoria et al 2018). Under Mediterranean climate, where the rainfall is scarce and unevently distributed, and the period with higher sunlight radiation is delayed respect to the rainfall season, NT provides higher available soil water in rainfed agriculture increasing the crop yields (Cantero-Martínez et al 2007).…”
