Conteúdo: 	Soil sampling is the first and fundamental step in an evaluation of soil fertility, interpretation and fertilizer
recommendation for banana crops. However, nutrient availability can vary in the soil due to fertilizer group
and application method. The aim of this study was to analyze nutrient distribution based on different
application techniques and different fertilizer groups and based on the results, determine the optimal area
for soil sampling in Santa Catarina?s banana crops. The experiment was conducted in Luis Alves, Corupá
and Massaranduba. Three fertilizer groups were tested (organic, organomineral and synthetic fertilizers) in
the following application techniques: broadcast application; single spot application, half-moon application.
The following main parameters were evaluated: fruit yield; nutrients available in the soil, nutrients available
in the leaves. Among the macronutrients, potassium (most demanded) and phosphorous (least demanded)
were analyzed with emphasis in order to determine the optimal area for soil sampling. All treatments
presented similar, fruit yield, nutrient concentration on leaves and soil. However, phosphorous and
potassium concentration significantly decreased with increasing distance from application site. The optimal
distance from the sucker plant front for soil sampling was determined based on each fertilizer group and
application method as the following: 100 cm to 110 cm for organic fertilizer applied in a single spot; 80 cm
to 100 cm for organomineral fertilizer applied in a single spot; 80 cm to 130 cm for synthetic fertilizer
applied in half-moon or single spot. Accurate area for soil sampling can favor more economical and
sustainable nutritional management of banana crops in Santa Catarina.
