Abstract

The spatial variability of nutrients, principally for carbon, nitrogen and phosphorus, and of some physicalchemical properties of the soil will be studied in the case of a forest-pasture succession in Rondônia. We will use different experimental sampling patterns standards varying fromone hundred square meters to dozens of square kilometers for the collection of data. The data will be analyzed by geostatic and statistical treatment in order to obtain a methodology to improve the estimates of stocks of nutrients in the soil and also ideal sampling patterns. (AU)
