Abstract Bahiagrass ( Paspalum notatum Flüggé) is a rhizomatous, perennial, warm‐season forage widely grown in the southeastern United States "UF Riata" bahiagrass more upright growing with greater herbage production when days are shorter compared most other cultivars. Lesser daylength sensitivity extends grazing season, but combination growth may negatively affect persistence under grazing, es...

The objectives of the current study were to determine the amounts of aboveand below-ground plant biomass production, P uptake by forage, and P concentration of cool-season grass forage as influenced by management and season. Five forage management treatments were evaluated over 3 years in smooth bromegrass (Bromus inermis Leyss) pastures. Management practices were: ungrazed (U), hay harvest/fal...

This chapter deals with the challenge to reduce nitrogen (N) excretion and the amount of N able to leach under pasture. N inputs need to be adjusted while limiting adverse effects on animal nutrition and milk production per cow and per hectare. The chapter starts with discussing the origin and variation of N flow in dairy cows. N intake is divided into N exported in milk and N excreted in faece...

Wild legumes constitute an important component of widespread pastures in the Mediterranean basin. This region is experiencing remarkable effects from climate change, and continuous monitoring of species and population dynamics is important in order to plan and enact valuable conservation programmes. Tripodion tetraphyllum (L.) Fourr. [=Anthyllis tetraphylla L.] (2n=16), belongs to the tribe Lot...

Grasslands in tropical environments are characterized by greater diversity than is found in temperate areas. In South Africa, greater diversity is found with the seasonally limited production which occurs on dystrophic soils under humid conditions in the sourveld, as opposed to the year round production that occurs on eutrophic soils under warm and drier conditions in the sweetveld. Most of the...

Large amounts of uranium waste rocks and tailings resulting from the exploitation and treatment of uranium ore at the Northern Guangdong mine (South China) have been accumulated in dams (tailing ponds). To reduce the dispersion of natural radionuclides into the environment, some dams were revegetated with arbor, bush and sward. Besides these plants, Miscanthus floridulu is the dominant plant gr...
