Conteúdo: |
O tratamento de sementes traz inúmeros benefícios para o sistema produtivo da soja, algodão e do milho, possibilitando boa emergência quando a semeadura coincide em períodos adversos, evitando, na maioria das vezes, a necessidade do replantio; garante a proteção das sementes e plântulas na fase inicial da cultura em função do controle exercido aos fungos presentes nas sementes e no solo, além de possibilitar a aplicação localizada do fungicida, com utilização de menor quantidade do produto e menor risco de intoxicação do homem e meio ambiente, sendo uma técnica de baixo custo e acessível a todos os produtores. |

The Brazil nut is considered one of the noblest trees of the Amazon biome and contains social, ecologic and economic importance to this region. The study of the spatial variance of the edaphic properties in native nut trees can direct future researches about more efficient samplings. The Geostatistics is the methodology utilized for this type of study, once that it considers the structural and random characteristics of a variable spatially distributed. This work sought to get a higher knowledge about the distribution of the nutrients in the soil, verifying the relationship with the occurrence of this species, to thereby provide subsidies to future forest management and maintenance/enlargement of the productivity in these areas. The soil samples were collected from 30 × 30 m on the line, in all of the lines in part of the study, totaling 60 samples. All of the points were georeferenced. The preparation of the samples for the sample preparation for the chemical analysis and the methods and calculations to determine the physicochemical variables studied were described by Nogueira and Souza (2005). The statistical and geostatistical analysis were conducted using the R computational environment, version 3.2.2. Most of the studied variables presented defined level. For the physical variables, there was predominance of the adjustment to the model of the gaussian variogram, follower by the spherical model. In the case of the chemical variables, there were two occurrences for each adjustment model (spherical, exponential and gaussian). The variables that best presented spatial relation with the occurrence of Brazil nut trees were the silt, clay, macroporosity, pH, phosphorus, zinc and copper.
