“…In addition, D-O and D-L diversification systems showed a better SOC-S balance with respect to the monocrop system; however, the absence of crop residues in considerable quantities and annual tillage for sowing were driving factors for the reduced accumulation of soil C in the different aggregate size classes. Similar findings were observed in Oliveira et al [93] and Martinez Mena et al [94], where SOC-S was not affected in the short-term. Moreover, the shortterm period of this field study (i.e., 4 years) to assess the diversification effect combined with severe environmental conditions, especially in the dry season months (temperatures above 40 • C, no rainfall events, extreme evapotranspiration rates), SOM-poor soils, low structural stability and parent material consisting of the sedimentary substrate (mainly, limestones and marls), which are easily erodible, hindered the diversification development and contributed to decelerate the SOC dynamics and C sequestration processes.…”

Soil particle aggregation and their associated carbon (C) and nitrogen (N) content can provide valuable diagnostic indicators of changes in soil properties in response to the implementation of different agricultural management practices. In this sense, there is limited knowledge regarding the impact of intercropping on soil organic carbon (SOC) and total nitrogen (TN) pools in aggregates. This study aimed to evaluate the short-term effect (4 years) of three crop diversifications in rainfed olive orchards on soil aggregation, SOC and TN concentration and SOC stocks (SOC-S) under semi-arid Mediterranean conditions. Olive orchards were diversified with Crocus sativus (D-S), Vicia sativa and Avena sativa in rotation (D-O) and Lavandula x intermedia (D-L) and compared with monocropping system (CT). Soil samples were collected at two depths (0–10 and 10–30 cm) and analysed for soil aggregate mass, SOC and TN content in aggregate-size fractions obtained by the wet-sieving method. Changes caused by crop diversifications on SOC-S were also determined. Overall, after 4 years, a reduction in aggregation values was observed. However, D-S increased the macroaggregates (>250 μm) percentage, Mean Weigh Diameter values, and Geometric Mean Value in the 0–10 cm. Across treatments, aggregate-associated C in 0–10 cm was higher in the D-S treatment, while in the 10–30 cm soil layer, the greatest values were found in CT. Regarding the SOC-S, after 4 years, significant losses were recorded under CT management in 0–10 cm (−1.21 Mg ha−1) and 10–30 cm (−0.84 Mg ha−1), while D-O and D-L showed similar values to those obtained at the beginning of the study. The highest increases in SOC-S were found in D-S, with an increase of 5.88% in the 0–10 cm and 14.47% in the 10–30 cm. Our results showed the high potential of the diversified cropping system to increase soil stability and SOC sequestration.

“…However, it was expected that the highest nutrient concentration in the durum wheat residue would be associated with lower biomass production, which in this case was after the canola crop, because of lower nutrient dilution (Marschner 2012). The highest K, Ca, and Mg concentrations in the durum wheat residue after the bean crop can be associated with the benefits of legume crops and using their residues on the microbial biomass activity and soil nutrient cycles (Watson et al 2017;Plaza-Bonilla et al 2018;Oliveira et al 2019).…”

“…Given that the highest durum wheat grain yield occurred after bean and that lower N and P concentrations resulted from the dilution effect, one would have expected a lower extraction of these nutrients in the durum wheat grain after bean. However, the highest nutrient extractions in both the grain and the residue were after bean; this can be explained by the higher grain yield after bean, and the benefits reported for legumes when used as the preceding crop and their residues are incorporated (Watson et al 2017;Plaza-Bonilla et al 2018;Oliveira et al 2019). For nutrient extraction in durum wheat residue, the highest values obtained after bean are explained by the higher concentration of some nutrients as a beneficial effect of using legumes and their residues in crop rotations (Watson et al 2017;Plaza-Bonilla et al 2018;Oliveira et al 2019), which is also associated with the highest residue production after bean.…”

The directly proportional trend between grain K extraction and the bean residue incorporation level was previously explained for the K concentration in durum wheat grain after bean with different residue levels associated with effects of increased availability of this nutrient as a direct input of the residue and beneficial effect on soil biomass (Watson et al 2017;Plaza-Bonilla et al 2018).…”

This study aims to evaluate the medium-term effect of two biannual rotations and four residue rate incorporation on durum wheat production and its nutritional composition and nutrient extraction. The effects of two biannual rotations of canola (Brassica napus L.) durum wheat (Triticum turgidum L.) and bean (Phaseolus vulgaris L.)-durum wheat and four incorporation rates (0%, 50%, 100%, and 200%) of residues of each preceding crop were evaluated after four seasons on durum wheat production and on its nutritional composition and nutrient extraction, in a volcanic soil in south-central Chile. Results indicated that the highest grain yield and residue production of durum wheat was obtained after bean (7.40 and 7.92 Mg ha −1 , respectively). In the grain were obtained lower N and P concentrations after bean, and higher K, Ca, and Mg concentrations in the residue. The extraction of most durum wheat grain and residue nutrients was higher after bean. Nutrient distribution in the durum wheat plant concentrated in the grain was 79.9 to 80.

“…By selecting Conservation Agriculture and using management practices such as no-till system and put plant residues on the soil surface, soil fertility and production stability can be increased in such systems [10][11][12] [13]. The main hypothesis is that faba bean-maize rotation with residue conservation on the surface and N fertilizer application increases yield and improves soil fertility compared with maize monocrop.…”

Achieving food security and environmental sustainability is a huge global challenge. Thus, the use of conservation Agriculture systems seems necessary. We investigated the effects of nitrogen fertilizer and various densities of faba bean ( vicia faba L.) on forage corn (Zea mays L.) production in the no-till system with faba bean residues preservation on the soil surface. The effect of faba bean densities on yield and its yield components, as well as soil chemical and physical properties, was studied Simultaneously. The results showed that various densities of faba bean and nitrogen fertilizer increased dry biomass production of forage corn by improving N content in plants, which was achieved by the density of 40 plants per m2 of faba bean + application of 200 kg N ha−1 of maize. Moreover, N content, crude protein, and fresh biomass production in forage corn were significantly increased by faba bean density and nitrogen fertilizer. Faba bean density also affected on yield and yield component of faba bean, and the highest nitrogen released value of faba bean root residues was obtained from the density of 40 plants per m2 and application of 200 kg N ha−1. Therefore, the density of 40 plants per m2 of faba bean in a rotation system with mays and application of 200 kg N ha−1 be recommended as a fertilizer control method where it reduces the application of N fertilizer and increases the sustainability of production in agricultural systems.
