Conteúdo: | Seasonal variation of nutrients in mango (Mangifera indica) trees in three soils of the dry pacific region of Costa Rica. I. Macronutrients.The nutritional status and the seasonal variation of N,P,Ca,Mg,K and Swas evaluated in mango trees of three different soils in the Dry pacific region of Costa Rica:Ustic Humitropept (Atenas), Typic Dystropept (Orotina), and Typic Ustropept (Liberia). The purpose of the research was to determine the nutritional condition of the orchards in relation to the soil concentrations in each region, and thoroughout the year. Three different tissue which was the second one in the branch from the outside and the Old Tissue which was the one in the third growth flushfrom the outside), and two varieties: Tommy Atkins and Irwin, N,P,Kand Mg behaved as movile elements within the tree, while Ca and S were inmovile within the tree, Higher concentrations of N,P,K, and Mg and lower concentrations of Ca were found in cv. Irwin when compared with cv, Tommy Atkins. N,P,Mg and S deficiencies were found in the three orchards. These low foliar concentrations of P,Mg and S corresponded to low ones in the soils. There were lower N,P,K,Mg and S concentrations during the periods of flowering, fruiting and fruit growth, while the Ca concentrations were associated to the rain pattern. Based on the results obtained in this study, sampling of the Intermediante Tissue in the time after harvest is recommended to obtain a homogeneous sample.
