Conteúdo: 	Soil penetration resistance penetration is property important to characterize the state of soil compaction in
cultivated systems. Thus, this work aimed to evaluate the impacts of management and moisture on soil
penetration resistance in an agroforestry system with oil palm. The research was carried out at an experimental
site, located in the county of Tomé-Açu, eastern Amazon, Brazil. The system is called the Biodiverse
Agroforestry System (AFS-BIO), with oil palm as the species with the greatest economic value. We collect
soil samples weeded circle oil palm (ACP); Harvest path (CAR); leaf pile (PIL) and diversified strip (DIV) in
depths 0-5; 5-10; 10-20; 20-30 and 30-50 cm of soil for determine gravimetric moisture. The penetration
resistance is determined by means of an impact penetrometer with a cone angle of 30°. Soil resistance in
periods of lower moisture is higher than in periods of high soil moisture. There is an increase in resistance with
the depth of the soil, which may possibly be influenced by the increase in bulk density. In the period of lower
moisture the soil resistance reached critical values, mainly in the harvest path, due to the passage of machines
in this management zone. Soil moisture and management are the main factors that directly influence soil
penetration resistance.
