                         {\`a} regi{\~a}o do vale do Para{\'{\i}}ba do Sul. Neste 
                         trabalho avaliaram-se atributos f{\'{\i}}sicos de um Latossolo

                         experimental de pinh{\~a}o manso consorciado com leguminosas 
                         herb{\'a}ceas perenes (Arachis pintoi e Calopogonio muconoides) 
                         em compara{\c{c}}{\~a}o {\`a} braqui{\'a}ria (Brachiaria 
                         brizantha), largamente cultivada na regi{\~a}o. Foram realizadas 
                         a caracteriza{\c{c}}{\~a}o e a an{\'a}lise de textura do solo, 
                         e determinaram-se os {\'{\i}}ndices de satura{\c{c}}{\~a}o e 
                         reten{\c{c}}{\~a}o de {\'a}gua, a resist{\^e}ncia do solo

                         ra{\'{\i}}zes na B. brizantha variou de alta a moderada, a 
                         partir de 30 cm de profundidade, e a adi{\c{c}}{\~a}o das 
                         leguminosas herb{\'a}ceas perenes (LHP) como culturas de 
                         cobertura em cons{\'o}rcio com o pinh{\~a}o manso reduziu essa 
                         resist{\^e}ncia e elevou a VIB m{\'e}dia do solo, de 4 mm h-1 
                         (B. brizantha), para 33 mm h-1. Conclui-se que a 
                         associa{\c{c}}{\~a}o de leguminosas herb{\'a}ceas com o 
                         pinh{\~a}o manso contribuiu para o melhoramento das 
                         caracter{\'{\i}}sticas f{\'{\i}}sicas e h{\'{\i}}dricas do 
                         solo. The cultivation of physic nut (Jatropha curcas L.) is a 
                         sustainable option for biodiesel production due to its adaptation 
                         to different agro-ecological conditions and its high content of 
                         non-edible oil grains. The possibility of its cultivation in 
                         degraded low fertility soils makes the physic nut attractive to 
                         the Para{\'{\i}}ba do Sul Valley region. This study evaluated 
                         physical attributes and water processes of an Oxisol which had 
                         been previously used for livestock and later converted to 
                         experimental farming. The soil was intercropped with perennial 
                         herbaceous legumes (Arachis pintoi and Calopogonio muconoides) in 
                         place of the original cover of Brachiaria brizantha, largely 
                         cultivated in the region. We determined the soil texture, the 
                         levels of saturation and water retention, soil resistance to root 
                         penetration and the basic infiltration rate of water into the soil 
                         (VIB). The soil resistance to root penetration in B. brizantha 
                         ranged from high to moderate at 30 cm depth, while the addition of 
                         perennial herbaceous legumes as cover crops intercropped with 
                         Jatropha reduced this resistance and increased the average soil 
                         VIB from 4 mm h-1 (B. brizantha) to 33 mm h-1. We conclude that 
                         the association of herbaceous legumes with Jatropha contributed to 
                         the improvement of the soils physical properties.",
