Última Deposition and decomposition of litter in periods of grazing and rest of a tropical pasture under rotational grazing 65 Ramalho,Israel Oliveira; Rezende,Claudia de Paula; Pereira,José Marques; Macedo,Robert de Oliveira; Santos,Camila Almeida dos; Monteiro,Rafael Cassador; Alves,Bruno José Rodrigues; Carvalho,Isabel das Neves Oiticica de; Urquiaga,Segundo; Boddey,Robert Michael. ABSTRACT: The objectives of this study were to determine the rates of plant litter deposition and decomposition in Marandu pastures (Urochloa brizantha cv. Marandu) under a) three forms of nitrogen (N) supply, b) at different stages of rotational grazing and c) to compare the single-exponential decay constant (‘k’) derived from litterbags with values derived from estimates of deposited and existing litter (DEL technique). The three N supply treatments were: without or with N fertilization (zero or 150 kg N ha-1 yr-1) or with the legume Desmodium ovalifolium. There were no significant differences (p<0.05) between existing litter and rates of litter deposition and decomposition between the three N supply treatments. The litter decomposition rate was...

ABSTRACT Evaluating the decomposition dynamics of vegetative residues from cover crops can provide a better understanding of nutrient release, which is fundamental when choosing a species that is adapted to local conditions. The objective of this study was to evaluate the decomposition rates and nutrient release dynamics of the shoot phytomass of different cover crops that have potential for agricultural use in the Recôncavo Baiano, Brazil. Crop residues of the following species were analyzed: sunn hemp (Crotalaria juncea L.) - CROT; velvet bean (Mucuna aterrima L.) - MUC; lab lab (Dolichos lab lab L.) - LAB; jack bean (Canavalia ensiformis [L.] DC.) - JB; white lupin (Lupinus albus L.) - WLUP; and Guinea grass (Urochloa maxima (Jacq.) R. Webster) - GRAS.... Tipo: Info:eu-repo/semantics/article Palavras-chave: Decomposition constant; Lignin/N; Half-life.
