Soil Phosphorus Transformations Following Forest Clearing for Pasture in the Brazilian Amazon

open access: yesSoil Science Society of America Journal, Volume 64, Issue 5, Page 1792-1804, September 2000., 2000
Phosphorus limits grass production in pastures planted on most cleared moist tropical forest, but little is known about soil P dynamics in these ecosystems. We describe changes to total P and different soil P fractions that occurred after the conversion of forest to pasture in the Brazilian Amazon State of Rond o ˆ nia.

Yield and Stability of Three Tropical Forage Grasses Cultivated as Pure or Mixed Stands

open access: yesGrass and Forage Science, Volume 80, Issue 2, April-June 2025.
ABSTRACT Multispecific pastures are considered more sustainable to animal production than monocultures. However, studies on mixtures of tropical grasses are underexplored. We aimed to assess whether a mixture of three contrasting growth strategies of perennial tropical forage grasses could outperform their respective monocultures in terms of forage ...

Nitrogen acquisition and retention pathways in sustainable perennial bioenergy grass cropping systems

open access: yesGCB Bioenergy, Volume 16, Issue 6, June 2024.
Perennial tall grasses sustain high biomass yield with minimal synthetic nitrogen (N) fertilizer, potentially by leveraging biological N fixation and nitrification inhibition. Enhancing these traits through research and breeding can further reduce their reliance on N fertilizer and thereby support more resilient and environmentally sustainable ...

Morphogenetic and structural characteristics of guinea grass pastures submitted to three frequencies and two defoliation severities. [PDF]

open access: yes, 2011
It was evaluated the morphogenic and structural characteristics of guinea grass under rotational at three grazing intervals and two defoliation intensities. Grazing intervals corresponded to the time needed by the forage canopy to reach 90, 95 or 100% of

Isolation of diploid and tetraploid Sexual plants in guineagrass (Panicum maximum Jacq.)

open access: yesJapanese Journal of Breeding, 1979
Sexually leproduclng plants (sexual plants) of guineagrass were screened by progeny tests for progressing cross breeding in this apomictic species. Two hundreds and thirty four plants of 86 guineagrass accessions were self-pollinated by bagging and/or open-pollinated.

Sources and rates of nitrogen fertilizer used in Mombasa guineagrass in the Brazilian Cerrado region [PDF]

open access: yesAfrican Journal of Agricultural Research, 2015
Brazilian Cerrado is constituted largely by extensive grazing. In this region, livestock production indices are low, because the producers do not perform a soil amendment. The aim of this work was to study a pasture with high production potential using sources and rates of nitrogen (N).
