“…Taking into account that coffee plantations require nutrient input into the soil in order to replenish the volume exported in the beans, soil fertility needs to be managed to maintain the aimed productivity levels annually. According to Guarçoni (2017), the improvement and maintenance of soil fertility can be achieved through fertilizers.…”

In Caparaó region, Brazil, in areas above 1000 m high, a second flowering (called late or from March) is common to take place, causing changes in the crop management for those intending to produce specialty coffees. The objective of this study was to evaluate physical and sensory aspects of arabica coffee from the Caparaó region, produced in traditional and late plantations in the same fields, using two fertilization regimes, one recommended by specific literature and another with the addition of extra fertilizers (33%), respecting the proportions amid them. The employed factorial analysis allowed identifying the interaction between the two levels of nutrition and the two harvests, for the analyzed attributes. The extra addition of fertilizers provided a reduction in the mean score of the fragrance/aroma and overall sensory attributes in the traditional harvest; and in the late harvest, it alone was responsible for raising the scores of the following sensory attributes: flavor, aftertaste, acidity, balance and total. The added extra amount of fertilizer, unassisted, altered the coffee physical aspects, reducing their defects/imperfections. Influência da florada e adubação adicional em aspectos físicos e sensoriais de café arábicaRESUMO: Na região do Caparaó, em áreas acima de 1.000 m de altitude, é comum ocorrer um segundo surto de florada (chamada de tardia, ou de março) que gera modificações no manejo de colheita para aqueles que pretendem produzir cafés especiais. O objetivo deste trabalho foi avaliar aspectos físicos e sensoriais de café arábica da região do Caparaó, produzido em lavouras com colheitas tradicional e tardia nos mesmos talhões, usando dois regimes de adubação, sendo um o recomendado pela literatura específica e outro, com a adição de 33% de fertilizantes extras, respeitando-se as proporções entre eles. O fatorial utilizado permitiu identificar a interação entre os dois níveis de nutrição e as duas colheitas para os atributos analisados. A adição extra de fertilizantes proporcionou redução na nota média dos atributos sensoriais fragrância/aroma e geral, na colheita tradicional, e a colheita tardia, isoladamente, foi responsável pela elevação das notas dos seguintes atributos sensoriais: sabor, finalização, acidez, balanço e total. A quantidade extra de fertilizantes adicionada, de forma isolada, alterou os aspectos físicos dos cafés, reduzindo-lhes os defeitos/imperfeições.

“…Arabica coffee is a high nutrient-demanding crop, and it has very limited bean yield if grown in acidic soils with low nutrient availability (Acuña-Zornosa & Sadeghian-Khalajabadi, 2020;Corrêa et al, 2007;Matiello et al, 2016;Mendonça et al, 2007;van Raij et al, 1996). In Brazil, either most coffee crops are grown on naturally acidic soils or on soils with problems of acidity and low fertility caused by crop nutrient removal, frequent use of ammonium-based fertilizers, or both factors (Guarçoni, 2017;Matiello, et al, 2016; van Raij et al, 1996). In this context, the application of limestone is essential to raise the soil pH, neutralize toxic Al 3+ , decrease the high availability of Mn 2+ , supply Ca and Mg, and increase the soil microbial activity (Chaves et al, 1984;Corrêa et al, 2007;Guarçoni, 2017;López-Báez et al, 2018;Matiello et al, 2016;van Raij et al, 1996).…”

“…Given that there is a strong relationship between base saturation (BS) and the pH in tropical soils (Guarçoni, 2017;van Raij et al, 1968), the most widespread acid soil amendment recommendations for Arabica coffee in Brazil are based on calculating the limestone rate required to raise the BS to a desired value. According to , limestone should be applied to raise the BS to 50% and the Mg 2+ concentration to a minimum of 0.5 cmol c dm −3 , considering the 0-to 0.2-m soil layer, with limestone application mostly in the plant canopy projection (fertilization band).…”

Limestone increased coffee yield and profitability more than phosphogypsum or their combination

et al. 2021

Soil acidity and low concentrations of exchangeable Ca and Mg are among the main factors that limit the Arabica coffee (Coffea arabica L.) yield in Brazil. Constant fertilizations, especially with ammonium‐based N, contribute to acidification in the soil region where they are applied. Coffee producers wonder if limestone and phosphogypsum, isolated or combined, can increase coffee yields. A field experiment was conducted from 2015 to 2020 in southeastern Brazil to evaluate the effect of sole application of limestone and phosphogypsum, or their combined application to young coffee trees (2‐yr old), on plant nutrition, yield, and profitability of Arabica coffee crop. Treatments included three limestone rates (0, 2,100, and 4,200 kg ha−1), two phosphogypsum rates (0 and 2,300 kg ha−1), and their combinations, which were band applied under coffee plant canopy. Limestone, in association with phophogypsum or when sole‐applied, increased the pH and the concentration of Ca and Mg in the soil, whereas the application of phosphogypsum increased Ca and SO4–S concentration. Coffee yields were increased by the sole application of limestone and phosphogypsum (to a lesser extent), but not when they were combined. The most successful treatment was the sole application of limestone, with increases of up to 44% (613 kg ha−1 yr−1 on average) in yield and 43% in economic returns.
