“…Regions 2, 3 and 4 represent 48%, 4.9% and 0.4% of the total area of the banana plantation, respectively, indicating that decompaction by subsoiling at varying depth and in specific regions will represent a lower energy expenditure, fuel consumption and carbon emission to the atmosphere, as well as greater operational capacity when this practice is compared to the conventional method. This pattern has been observed by Machado et al (2015) and Cortez et al (2020), who verified a reduction in expenses with the use of localized subsoiling at varying depth.…”

“…Decompaction by subsoiling is indicated at three different depths: 0 to 0.40 m, 0 to 0.30 m and 0 to 0.20 m, characterized by regions 2, 3 and 4, respectively. This type of localized management is extremely important, since it is possible to mobilize only compacted layers, maintaining their structure and organic matter protected within aggregates and avoiding excessive disaggregation (Tiecher, 2016;Cortez et al, 2020).…”

“…Soil penetration resistance (SPR) is one of the main indicators of soil physical quality (Tiecher, 2016;Cortez et al, 2020). Studies evaluating the spatial variability of SPR and its effects on attributes of soils cultivated with cereals, grasses and legumes are easily found in the literature, but there are few studies conducted in orchards, especially in banana plantations.…”

The present study aimed to investigate the spatial variability of soil penetration resistance (SPR) in cultivation areas of ‘BRS Princesa’ banana, to evaluate its effects on the chemical and physical attributes of the soil and to indicate localized management. The experiment was carried out in an area of cultivation ‘BRS Princesa’ banana, in which 60 georeferenced points were recorded. SPR was measured from the cone index to 0.40 m depth using an impact penetrometer. Disturbed samples were collected at depths of 0-0.05, 0.05-0.10, 0.10-0.20 and 0.20-0.40 m and the soil attributes pH, Ca, Mg, Al, Na, K, P, H + Al, SB, T Value, V%, total sand, total clay, silt, TOC, POC, MAOC and gravimetric moisture were determined. The data were subjected to descriptive statistics, Pearson’s linear correlation and geostatistical analysis. SPR values in subsurface suggest greater compaction in subsurface and the significant correlations with soil attributes indicate losses for banana plants, so localized management should be carried out. It was found that 46.7% of the total area of the banana plantation does not need to be decompacted, and localized subsoiling at a varying depth is indicated in the other regions.

“…Soil tillage with chiseling only in the row presents itself as an alternative to conventional management with chiseling in total area, resulting in economic and environmental gains, with no impact on plant growth. Cortez et al (2020) observed that the localized subsoiling operation led to saving of 43.5% in fuel consumption and increasing of 59.4% in operating capacity, factors that reduce the cost of production and mitigate CO 2 emission to the atmosphere. When evaluating CO 2 emission due to tillage systems in the same area of the Oxisol of the present study, Souza et al (2017) identified increase of 315.4 kg CO 2 •ha -1 in the emission at the site with chiseling in total area, when compared to localized chiseling.…”

“…More than 75% of the sugarcane root system is close to the planting row, being distributed up to 0.40 m deep and up to 0.30 m from the center of the planting row (Otto et al 2009;Clemente et al 2017). Thus, localized agricultural managements in the sugarcane planting row tend to be viable for the crop, reducing the cost of chiseling in soil tillage, fuel consumption, and CO2 emissions to the atmosphere, besides not interfering with yield (Tenelli et al 2019;Cortez et al 2020).…”

Is localized soil tillage in the planting row a sustainable alternative for sugarcane cultivation?

The aim of this study was to evaluate the physical quality of the soils by evaluating the variation of soil penetration resistance, resulting from tillage with chiseling in the planting row and in total area, and the possible interferences of the managements in sugarcane yield.The study was carried out in southeastern Brazil, in areas under Oxisol and Ultisol, which are the two soils with the greatest representativeness of sugarcane cultivation in the country. The treatments consisted of soil tillage in total area and localized tillage in the sugarcane planting row, with 10 replicates. Undisturbed soil samples were collected in the 0-0.10, 0.10-0.20, and 0.20-0.40-m soil layers in sugarcane rows and interrows in both soil types for penetration resistance determination in laboratory. Samplings were carried out at three times, the first after soil tillage, the second after sugarcane planting, and the third six months after planting. Compared to the system with tillage in total area, localized tillage promoted higher values of soil penetration resistance in sugarcane interrows. However, this was not enough to reduce the crop yield. In the planting row, there are no differences between tillage types for soil penetration resistance. Localized soil tillage in sugarcane crop is a conservation and sustainable alternative that can replace soil tillage in total area, not interfering in the PR determined in the crop row and not altering the stem yield, regardless of the soil type.
