“…However, the values found even at the maximum Ψ m : 3000 kPa, θ: ± 0.20 cm 3 cm -3 , PR: 1.7 MPa are related to less than 2.5 MPa values for PR (Figure2), which according to several authors is the PR value in which root growth is limited for most crops (Bengouch & Mullins, 1990;Keller et al, 2014;Silva et al, 2015;Peixoto et al, 2019). This is an indicative of the management used to cultivated coffee crop was adequate to soil structure quality maintaining some environmental sustainability.…”

“…For tensions above 1500 kPa the WP4-T psychrometer was used (Carducci et al, 2013). After the equilibrium of the samples at the predetermined Ψ m , was performed the penetration resistance, using a penetrograph model MA 93, with constant speed (10 cm min -1 ), straight circular cone (45°) and radius of 1.92 mm (Silva et al, 2015;Peixoto et al, 2019). After this procedure all the samples were weighed and then oven-dried at 105-110°C for 48h to determine the water content corresponding to Ψ m (Genuchten, 1980), totaling 36 samples.…”

Our goal was to analyze the impact of a multipractice soil conservationist system on coffee production in tropical soils (LATOSSOLO VERMELHO-AMARELO caulinítico/kaolinitic Haplustox and LATOSSOLO VERMELHO-gibbsítico/gibbsitic Acrustox) in Minas Gerais, Brazil. In the experimental area, the soil management involved a set of multiple conservationist practices during cultivation for more than 3.5 yrs. Soil samples were collected at 0-5, 10-15, and 20-25 cm depths at two positions: planting rows and between rows. The soil physical and mechanical properties were determined, with a focus mainly on the preconsolidation stress model (preconsolidation stress versus matric tension). For the purpose of analysis, a split-split plot experimental design was implemented. A linear mixed regression model (LMR) was fitted, and Wald’s test was performed (P < 0.05). An improvement of soil physical quality for both Oxisols was observed at the planting row position. The effects of multipractice soil management after 3.5 yrs of cultivation in association with increased gibbsite content could promote new soil structure organization, as revealed by LMR, resulting in more resilient soils (between rows) and increasing the resistance to external pressures on gibbsitic Acrustox. Overall, the findings herein are in concordance with global trends towards conservationist practices that may alleviate soil compaction in agricultural systems to maintain environmental sustainability.

“…The planting system adopted in the farms is SPD, possibly inserted in the area volume cited by Peixoto et al (2019), whose understanding is anchored in the molds proposed by Phillips et al (1980), presenting the gains gauged by Salton, Hernani and Fontes (1998). Cotton planting in the research region is done in the conventional system (Clawson et al, 2008) to the detriment of the adensed system as discussed in Rosolem et al (2012) and Kazama et al (2016).…”

“…The application of cotton occurs in two main segments: the textile that absorbs the lint, which in economic terms is the main primary cotton product (Amaral et al, 2018), which can represent up to 40% of the fruit, and the nontextile that uses the seed in the production of oil and derivatives, feed production (Li & Robinson, 2011 The cotton chain is characterized by, among other things, the intensive use of technology (Conab, 2018) and the high capacity to add value (Abrapa, 2017). Technologies such as the No-till System (SPD) have been adopted since the 1970s in Brazil, where more than 32 million hectares of land are under this system (Peixoto et al, 2019). SPD is characterized by non-involvement, permanent soil cover and crop rotation, increasing the sustainability of ecosystems (Salton, Hernani & Fontes, 1998).…”

The study aims to study the operations of the cotton chain at Agro-industrial Cooperative Holambra II, especially the operations of planting, harvesting, processing and storage and destination of byproducts. Of a basic nature, with a qualitative focus and exploratory descriptive objectives, the Case Study approach was used, supported by bibliographic research. Semi-structured interviews, documentary research and structured observation were the tools used in data collection. The Cooperative implemented changes in its organizational and compliance structure, seeking to increase its efficiency in decision-making, in addition to expanding its competitive advantages with better market positioning. The 2020/21 crop showed a sharp reduction in planted area, in view of the uncertainties caused by the Covid-19 pandemic, in addition to competition from other products, with a consequent drop in production, and productivity above the average of the last five harvests. The Cooperative's strategy for anticipating the harvest period provides conditions for making the product available on the market in advance, with the possibility of obtaining higher prices. In the 2019/20 harvest, the production of plume at the Cooperative was equivalent to more than 70% of the state production. The study contributes to the expansion of the study of agricultural cooperatives in the field of management, focusing on the production of cotton, which produces the most important of textile fibers.Probably, the COVID-19 pandemic will cause a significant contraction in world trade in 2020. Preliminary indicators already point to sharp falls in the first and part of the second half of 2020. For the first time since the 2008-2009 crisis, the volume of world trade in goods has plummeted in the first half of 2020, under pressure from rising trade tensions, especially between the United States and China, and weakening economic growth, particularly due to COVID-19.Andressa Vieira da Cruz et al.

“…Soil physical quality properties such as bulk density, porosity, water retention capacity, and penetration resistance, indirectly affect crop development and yield (Hargreaves et al, 2019). In the no-tillage system, restrictions related to compaction may be greater (Peixoto et al, 2019), since soil mobilization is restricted to the sowing line.…”

Cultivated soils, when submitted to agricultural practices, tend to compact due to the pressure exerted by agricultural machines and implements, a process that compromises soil quality and system sustainability. Specific properties of each soil, such as particle size and organic matter content, interfere with the process and degree of compaction and, consequently, plant growth. This study aimed to analyze the effect of different degrees of compaction (DC) on soil physical properties and black oat (Avena strigosa Schreb) growth. For this purpose, four soils were collected: Latossolo Vermelho distrófico retrático (Ferralsol LV CN), Cambissolo Húmico alumínico típico (Cambisol CH LG), Nitossolo Bruno distrófico típico (Nitisol NB PA), and Nitossolo Bruno distrófico húmico (Nitisol NB SJ). They were submitted to five degrees of compaction (bulk densities corresponding to 80, 85, 90, 95, and 100 % DC), defined by their relation to the maximum density obtained by the Normal Proctor Test. For each DC, porosity, soil water retention curve, penetration resistance, hydraulic conductivity, and aeration capacity were determined. In a greenhouse, the oats were cultivated in the four soils with five different degrees of compaction. The experiment was carried out in a completely randomized design, factorial scheme, and five replications. Crop measurements included the growth rate, shoot dry matter, and forage quality analysis. Soil compaction changed the physical properties of soils. In all tested soils, macroporosity and total porosity decreased, more intensely at LV CN. It had macroporosity below the critical level (0.10 m 3 m-3) from DC 85. Hydraulic conductivity also decreased in all soils, which is evidence of significant environmental degradation from DC 90 onwards. Microporosity increased in the four soils due to compaction effect, and it is one of the reasons why permanent wilting point has increased. It resulted in a problem at NB SJ , mainly because it reduced the available water volume at DC 90, 95, and 100. Penetration resistance has also increased from DC 80 to 100 at all soils, exceeding the limit of 2 MPa in DC 80 for NB SJ , DC 85 for NB PA and LV CN , and DC 95 for CH LG , representing a risk to root development. Regarding black oat crop, there was a reduction in shoot dry matter only in Cambisol and in the higher DC, fiber content keeps within a satisfactory amount, without affecting forage quality in all soils and DC, thus showing that black oat is tolerant to compaction.
