“…We observed that the pesticidefree management along with adequate fertilizer use have provided sufficient root development for the species grown at our site. This is supported by the satisfactory yields in the different systems as shown by Kruchelski et al (2021). Moreover, Dominschek et al (2021) indicated that the management applied in the experimental area is an economically viable and efficient nonchemical strategy to manage weeds and produce grains.…”

“…The soil was chisel ploughed down to 0.40 m depth and subsequently harrowed (<0.20 m). After that, the experimental area received between 8 and 10 ton ha −1 sewage sludge treated by the N-VIRO ® process for acidity correction as described by Kruchelski et al (2021). Then, the area was cultivated with black oat (Avena strigosa) as a cover crop, which was fertilized with 100 kg ha −1 of P 2 O 5 .…”

“…The CLF, CF, and LF systems are in an alley-cropping spatial design with the seedlings planted at single rows, following the contour lines, at 14 m × 2 m spacing, obtaining 357 trees ha −1 and occupying about 14.3% of the area of the integrated systems. Details about forest component can be found in Kruchelski et al (2021). In LF, the animal component followed the stocking rate adjustments described in system L, while the CF treatment had in the first 3 years black oats cultivated in winter, and sunflower (Helianthus annuus) varieties Aguará 4 and Aguará and maize hybrids 2B655HX, 30F53VYHR-early and P2866H-super early in summer.…”

Single farming systems (SFS) such as monocultures may negatively affect soil structural quality. This study tested the hypothesis that integrated farming systems (IFS), i.e., the combination of cropping and forestry and/or livestock farming, improves soil structural quality, root development and soil organic carbon. An experimental area was set up in 2012 at the Canguiri experimental farm belonging to the Federal University of Paraná, Southern Brazil. The soils are predominantly Ferralsols. The experimental treatments representing different farming systems, organized in a random block design with three replicates, were: Forestry (F), Conventional Crop Production (C), Livestock (L), and integrated Crop-Forestry (CF), Crop-Livestock (CL), Livestock-Forestry (LF), and Crop-Livestock-Forestry (CLF). In situ measurements and sampling were carried out in the 0–0.3 m layer during summer 2019/20, and included soil penetration resistance (PR), soil structural quality based on visual evaluation of soil structure (SqVESS scores), root length (RL), root volume (RV) and soil organic carbon content (SOC). Soil structural quality, penetration resistance, root length and volume, and SOC varied between farming systems, but no significant differences were found between single (C, L, F) and integrated farming systems (CF, CL, LF, CLF). The single system Forestry (F) and the integrated systems including forestry (LF, CF, CLF) tended to have higher SqVESS scores, i.e. poorer soil structural quality, and higher PR, which we associate with the generally drier soil conditions that are due to higher soil water uptake and higher interception and reduce the frequency of wetting-drying cycles. Roots were concentrated in the shallow soil layer (0–0.1 m depth), and this was especially pronounced in the Crop (C) single farming system. Based on the measured values, our results suggest an acceptable soil structural quality in all farming systems. Our data revealed strong, significant relationships between soil structural quality, penetration resistance, root growth and SOC, demonstrating that improvements in soil structure results in lower soil penetration resistance, higher root volumes and higher SOC, and vice versa. Soil PR was positively correlated with SqVESS (R2 = 0.84), indicating that better soil structural quality resulted in lower soil mechanical resistance. This, in turn, increased root length and volume, which increases carbon input to soil and therefore increases SOC in the long run.

The objective of this work was to compare the height-diameter relationship, described by nonlinear biological models, in Eucalyptus benthamii in monoculture forestry and in three different integrated crop-livestock systems (ICLS): crop-forestry, livestock-forestry, and crop-livestock-forestry. The trees were evaluated during seven years after planting. Five nonlinear biological models were fitted to evaluate the height-diameter relationship, and Gompertz’s model was selected to describe the data, although all models described satisfactorily the height-diameter relationship of the trees in the ICLS. The analysis of the data showed that there is no similarity between monoculture forestry and the ICLS as to the height-diameter relationship. In addition, the height-diameter relationship in E. benthamii changes between the different ICLS. Particularly, two systems with cattle provide the same values of maximum growth rate, asymptote, and inflection point of diameter at breast height. Furthermore, with the integration of cattle into the tree component, the produced trees show lower asymptotic heights, with larger diameters when the average tree heights of the ICLS are equal.
