Boron translocation in coffee trees
Plant and Soil, 2006Boron deficiency in coffee trees (Coffea arabica) is widespread, however, responses to B fertilizer have been erratic, depending on the year, method, and time of application. A better understanding of B uptake, distribution, and remobilization within the plant is important in developing a rational fertilization program. Field and greenhouse experiments

, 2008 Accumulation of Macronutrients for the Conilon Coffee Tree
Journal of Plant Nutrition, 2007ABSTRACT Besides its importance in Brazil, little information exists about the mineral nutrition of the Conilon coffee-tree. As a mean of characterizing its macronutrients accumulation an experiment was performed using the clone no. 2 of the clonal composite EMCAPA 8111.

Legume Trees in the Coffee Agroecosystem of Puerto Rico
2008Soils representative of the coffee region (Humatas and Los Guineos Series) were placed in 20-L plastic pots and seeds of Mimosoideae and Papilionoideae planted. Plants were evaluated for growth at three months and harvested at six months. Nodule number, nodule weight, and acetylene-reduction activity (ARA) were measured.
