Resumo: In arabica coffee crops grown at high altitudes with lower temperatures, soil fertility can be improved by condensed spacing. However, at low lands with warmer temperatures in which conilon coffee is grown, the effect of close spacing on the soil characteristics may change. Aiming to determine the effect of coffee-trees close planting grown with or without NPK fertilization on the soil fertility characteristics, soil samples were collected (0-20 and 20-40 cm depth) within four different conilon crop spacings (2,222; 3,333; 4,000; and 5,000 plants/ha). It was determined pH, H+Al, effective CEC (t), pH 7.0 CEC (T), base saturation (v), aluminum saturation (m) values and organic matter (OM), P, K, Ca2+, Mg2+ and Al3+ contents. The analytical results were compared by Student t test and regression analysis. Conilon coffee-trees with close planting only changed soil fertility characteristics when coffee plants received annual NPK fertilization. Close planting substantially increased P and K contents and the T value in the upper soil layer and P and K contents and T, t and H+Al values in the lower soil layer.

O café conilon é cultivado em regiões baixas e quentes, o que pode modificar os efeitos do adensamento sobre a fertilidade do solo. Visando determinar a influência do adensamento de plantio do café conilon, com ou sem adubação, nas características da fertilidade do solo, foram coletadas amostras de solo (0-20 e 20-40 cm de profundidade) em quatro densidades de plantio (2.222; 3.333; 4.000 e 5.000 plantas/ha). Foram determinados os valores de pH, H+Al, CTC efetiva (t), CTC pH 7,0 (T), saturação por bases (V) e saturação por alumínio (m) e os teores de matéria orgânica (MO), P, K, Ca2+, Mg2+ e Al3+. Os resultados analíticos foram comparados pelo teste t de Student e por análise de regressão. O adensamento de plantio do café conilon só modificou as características da fertilidade do solo quando as plantas foram adubadas anualmente com NPK. O adensamento de plantio aumentou substancialmente os teores de P e K e o valor de T, na camada superficial, e os teores de P e K e os valores de T, t e H+Al, na camada subsuperficial do solo.UEL2011-08-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1679-0359.2011v32n3p94910.5433/1679-0359.2011v32n3p949Semina: Ciências Agrárias; Vol. 32 No. 3 (2011); 949-958Semina: Ciências Agrárias; v. 32 n. 3 (2011); 949-9581679-03591676-546Xreponame:Semina.
