Production and quality of Urochloa decumbens (stapf) r.d. webster forage co-related to the physical and chemical properties of the soil

Abstract: RESUMOSubmetido em 27/12/2014 Frequently degraded pastureland characterized by low soil fertility and compacted surface is the basic environment of Brazilian livestock. The physical and chemical characterization of soil and its co-relationship with forage production are determining factors for performance of animals raised on pasture. The objective was to analyze the forage production of Urochloa decumbens grass correlated, linearly and spatially, with physical and chemical attributes of a savannah soil in S… Show more

“…This increase may be related to the intense organic matter (OM) degradation and nitrogen recycling in the shaded soil, which is influenced by the higher nitrogen availability and its absorption by plants (Xavier et al, 2014). Dalchiavon, Montanari, and Andreotti (2017) reported positive correlation between forage CP content and soil OM and moisture contents when evaluating Urochloa decumbens DM yield regarding the physicochemical attributes of the soil, emphasizing the relevance of agricultural practices aiming to raise soil OM content, since the benefits for increasing the CP content in the forage become evident.…”

“…The NDF concentration higher than 60% is negatively related with animal voluntary intake (Van Soest, 1994). Generally, in tropical forages the NDF content is higher than 60% (Dalchiavon et al, 2017;Lagunes, Pell, Blake, Lagunes, & Rodríguez, 2018). As such, the results found in this study can be considered satisfactory.…”

“…Quando uma variável estatística qualquer possuir distribuição de frequência do tipo normal, a medida de tendência central mais adequada para representá-la deve ser a média; em contrapartida, será representada pela mediana, ou pela média geométrica, caso seja do tipo lognormal (DALCHIAVON et al 2017). Na estação chuvosa, para o atributo UG, a média foi de 0,21; a mediana para CBM, C-CO 2 e qCO 2 foram, respectivamente, 375,5; 1,5 e 4,0.…”

“…When any statistical variable has a normal frequency distribution, the most suitable measure of central tendency to represent it is the mean. Conversely, if it has a lognormal distribution, it can be represented by the median or mean (Dalchiavon, Montanari & Andreotti, 2017). Shanmugam and Chattamvelli (2016) highlighted the relevance of skewness and kurtosis in such study, stating that skewness quantifies the distribution bias regarding the mean, while kurtosis measures the peak (or flatness) of a distribution.…”
