“…Coffee cultivation in the Upper São Francisco region (MG -Brazil) is exposed to the weather, in some cases requiring irrigation or the implementation of special techniques that increase the retention and the water storage in the soil (Martins et al, 2007). The practice of gypsum in the coffee culture in this region was adopted in order to allow the plants to increment their root system and explore a greater volume of soil and to increase the absorption of water and nutrients, thereby maintaining greater vegetative vigor during most of the year, even in times of drought (Carducci et al, 2014a;Ramos et al, 2013;Serafim et al, 2013;Silva et al, 2015;Silva et al, 2019a).

“…The use of gypsum as a soil conditioner in depth is a practice employed disparately regarding its conditions of use and management. Several studies have been carried out on the use of high doses of gypsum in the coffee crop, with effects that range from the increase of the Ca +2 concentration in the soil solution (Ramos et al, 2013), to the highest uniform distribution of the root system (Carducci et al, 2014a;Carducci et al, 2014b;Carducci et al, 2015;Serafim et al, 2013), to the reduction of susceptibility to soil disintegration (Silva et al, 2013, Silva et al, 2014, to the reduction of crop water deficit (Silva et al, 2015), to the soil moisture percentage and coffee yield (Silva et al, 2019a). However, there are no reports on the effect of applying high doses of gypsum on the biological and biochemical parameters of the soil in coffee cultivation.…”

The objective of this study was to determine the influence of increasing doses of agricultural gypsum on the quality of the soil biochemical parameters in coffee cultivation (Coffea arabica L.) over two climatic seasons in the Brazilian Cerrado. Soil samples were collected in two seasons (dry and rainy season), at 0.00-0.10 m depth of an Oxisol, submitted to doses 0 (GSA); 3.5 (G3.5); 7.0 (G7.0) and 14 (G14) t ha-1 of agricultural gypsum in the coffee planting line. The biochemical parameters evaluated were: total organic carbon (TOC); microbial biomass carbon (MBC); soil basal respiration (SBR); absolute enzymatic activities [Urease, acid phosphatase, hydrolysis of fluorescein diacetate (FDA)], and enzymatic activity per unit of MBC. The significant effect (p ≤ 0.05) of gypsum doses was observed for MBC and SBR, which were higher in the treatment with G7.0 application. TOC, the enzymatic activities of Phosphatase and the FDA showed no differences between treatments. On the other hand, the specific enzymatic activities by MBC were used to describe the differences between the doses of gypsum applied, generally with greater activity in treatments G7.0 and G14. The accumulated coffee productivity was higher in G14 treatment. The results presented confirmed that the biochemical parameters of the soil are key in the evaluation of changes in soil use, and that the increase in gypsum favors activity and microbial biomass.

“…More recently, Urochloa has been intercropped with perennial crops, such as coffee (Franco Junior et al, 2019;Silva et al, 2019) and citrus (Auler et al, 2008;Martinelli et al, 2017). Cultivated as stripes between rows, Urochloa protects the soil, reduces erosion, increases infiltration, suppresses weeds and cycles nutrients (Auler et al, 2008;Ragassi et al, 2013;Favarin et al, 2018).…”

“…Moreover, while residues on soil surface may not immobilize N, root residues can decrease N absorption of the next crop . Root turnover is a function of climatic conditions, root diameter and composition (Gill and Jackson, 2000) and can be slower than the shoot residues (da Silva et al, 2019). According to Urquiaga et al (1998), more root biomass increased N immobilization and grasses had more nondecomposable C in the roots, reducing decomposition process and immobilizing N. Urochloa root biomass decay was enhanced with N fertilization and moderate grazing (da Silva et al, 2019), but after 512 days of incubation 30% of the root biomass was remaining.…”

Increasing biodiversity is an important issue in more secure and sustainable agriculture. Diversified systems are more resilient to climate change, environmental stresses and enhance soil health, nutrient cycling and nutrient use efficiency. In tropical agroecosystems, cover crops and intercrops are an alternative toward a more diverse and sustainable production. Urochloa spp. (syn. Brachiaria spp.) are perennial grasses, known for their high biomass production. They are commonly used as cover and companion crops in conservation agriculture in the tropics and the residues left in the field after cutting protect the soil and provide nutrient to the next crop cycle or intercropped culture. Urochloa species roots are vigorous, abundant and deep, as opposed to the more shallow and scarce roots of common crops. These traits contribute to carbon sequestration, soil organic matter stabilization and nutrient cycling. Urochloa roots also improve soil physical characteristics and influence soil nutrient dynamics, reducing nutrient losses and enhancing cycling, what is key to achieve greater nutrient use efficiency in agriculture. For instance, Urochloa root exudates can reduce nitrogen losses by denitrification and leaching through a process called biological nitrification inhibition; root exudates can mobilize recalcitrant phosphorus from soils and make it available for plant uptake; the deep roots of these grasses have the potential to recover nutrients that are virtually lost away from the root zone of other crops. This review compiles scientific progress regarding the introduction of Urochloa in agroecosystems, mainly on the aspects related to the contribution to more secure and sustainable agriculture.

“…Water determines the success of coffee farming, since it influences the phenology of the plant and, consequently, its productivity, product quality and commercial viability (SILVA et al, 2019). The root system of the coffee varies depending on species, genotype, plant age, season, crop density, biotic stresses, texture, and soil structure (PARTELLI et al, 2014;RONCHI et al, 2015) Although the root system of coffee has its development characteristics linked primarily to the plant genetics, other factors can also modify its spatial distribution; e.g., amount of water present in the soil (BARRETO et al, 2006) and nutrient availability to plants (VICENTE et al, 2017).…”

The aim of this study was to evaluate the effect of irrigation levels on the root system of drip-irrigated coffee plants in western Bahia State (BA), Brazil. The experiment was carried out on Café do Rio Branco farm, located in Barreiras - BA, using adult plants (approximately 3.5 years old) of coffee variety Catuaí Vermelho IAC 144. The experiment was set up as a randomized block design with three treatments corresponding to the irrigation depths of 75, 100 and 150% as determined using Irriplus software. After the fourth harvest, the coffee root system was assessed to determine root length density (RLD) and root weight density (RWD) in different sampled layers. A greater concentration of roots (RLD and RWD) was observed in the surface layer (0-20 cm) and under the lateral line (at 30 and 70 cm from the orthotropic branch). The irrigation depth of 75% provided the highest concentration of roots (RLD and RWD) in the 0-10 cm layer. Keywords: Drip irrigation, Coffea arabica L, root system.

O objetivo deste trabalho foi avaliar os efeitos de diferentes lâminas de irrigação sobre o sistema radicular do cafeeiro irrigado por gotejamento na região Oeste da Bahia. Realizou-se o trabalho na fazenda Café do Rio Branco, localizada em Barreiras - BA em cafeeiros adultos, aproximadamente 3,5 anos de idade, da variedade Catuaí Vermelho IAC 144. O experimento ocorreu no delineamento em blocos casualizados, composto de 3 tratamentos, correspondentes à 75, 100 e 150% da lâmina de irrigação determinada pelo software Irriplus. Após a quarta safra, procedeu-se às avaliações do sistema radicular do cafeeiro, onde foi determinada a densidade de comprimento radicular - DCR e a densidade radicular – DR em diferentes camadas amostradas. Observou-se maior concentração de raízes, DCR e DR, na camada superficial (0-20 cm) e sob a linha lateral (30 e 70 cm de distância do ramo ortotrópico). A lâmina de irrigação correspondente a 75% proporcionou maior concentração de raízes (DCR e DR) na camada de 0 a 10 cm. Palavras - chaves: Irrigação localizada, Coffea arábica L, sistema radicular
