Abstract: South American natural grasslands are composed of several species with different growth strategies, with variations in specific leaf area (SLA), leaf dry matter content (LDMC), specific root length (SRL) and specific root area (SRA). The objective of this study was characterizing in grasses cultivated with different levels of phosphorus (P) in the soil if species with higher leaf and root area production per unit of dry matter have higher tissue P concentration, P use efficiency and higher dry matter yield.

“…After the collection procedure was over, samples were air-dried, homogenized, sieved in 2-mm mesh and featured based on their fertility (Table 1). Marques et al (2020). Vegetative propagation of the investigated species was carried out every two months, for one year, in order to expand the plant bank and increase homogeneity between seedlings deriving from each species.…”

“…Urochloa) species, which might diminish genetic resistance to pests and diseases (USDA, 2020). On the other hand, the genus Paspalum is native to the Americas and is considered an alternative for diversification in Brazilian cultivated pastures (Manzur et al, 2020;Marques et al, 2020).…”

“…Native grasses may have different adaptive mechanisms for P uptake and use in environments limited by this nutrient (Aerts and Chapin, 1999), resulting in different P content in aboveground biomass. Furthermore, plant growth characteristics that result in differences in leaf anatomy can alter the efficiency of light interception (Marques et al, 2020a) and so, within the same metabolic efficiency group, the dilution of N and P may be different (Lemaire et al, 2019). Thus, the study of the dilution of N and P in dry matter over productive periods in different native species can improve fertilization guidelines for natural grasslands in Southern South America.…”
