“…Increased organic carbon and nutrients in the soil due to animal droppings in grazing areas has been reported in other studies (Kurz et al, 2005;Lessa et al, 2014), as well as decreased ground cover by overgrazing (Mekuria & Aynekulu, 2013;Palacio et al, 2014). This contributes to increasing the magnitude of the processes in H D .…”

“…This, in turn, increases the potential of loss through runoff. Ebeledike et al (2010), Sath et al (2012) and Lessa et al (2014) reported that the amount of nutrients released by animal faeces and urine depends on the type of animal and its diet.…”

“…Environmental degradation of dry areas directly affects the social development of the surrounding region due to reduced water availability as well as food and energy production, leading to more severe social vulnerability and socioeconomic conflicts (Döll et al, 2015). Research studies have shown that livestock, one of the most important economic activities in the rural Caatinga , effectively contributes to cycling of soil nutrients (Van Beek et al, 2009;Ebeledike et al, 2010;Sath et al, 2012;Lessa et al, 2014).…”

Fallow Reduces Soil Losses and Increases Carbon Stock in Caatinga

This study aimed at evaluating whether 10 years of fallow was sufficient to restore a degraded hillslope in the semi-arid Caatinga biome, Brazil. For this purpose, runoff, erosion, loss of nutrients and organic carbon were measured on two comparable hillslopes: one was left fallow and the other degraded caused by overgrazing. Fallow management reduced runoff (36%), soil loss (65%) and organic carbon loss (81%) in comparison with the degraded hillslope. However, the fallow did not significantly reduce nutrient loss. Animal grazing has been shown to influence the nutrient cycle in the soil. The loss of organic carbon shows significant correlation with the loss of other nutrients, and may be used to estimate nutrient loss. Results show that a decade of fallow did not promote significant changes in the loss of nutrients, but was enough to reduce runoff, erosion and loss of organic carbon.

“…Nitrogenfertilizer efficiency is directly related to N 2 O emission, which is termed denitrification process [16,46,47]. In Brazilian Cerrado, the NH 3 -N and N 2 O through denitrification were observed to be the most important process of N-losses from cattle excreta for 7 months of rainy season in extensive pasture [48]. As reported by [7], the emission of N 2 O in grazed pastures is partially associated with C and N deposited from the animal excreta on soil (urine and dungs) under anaerobic conditions, as the case of soil compaction caused by animal trampling.…”

New Perspectives in Forage Crops

There is a concern about the growing population and limitation in natural resources which are taking the population to direct its agricultural systems into a more productive and efficient activity, looking to avoid a negative impact on the surrounding environment. The industry energy expended to produce nitrogen (N)-fertilizer is considered an indirect consumption of energy in agriculture, which is higher with an increasing forage yield. Nitrogen is the key nutrient associated with high-yielding production in forage grass and grain crops. The aim of this chapter is to introduce the best management practices (BMPs) for N-fertilizer application in forage grasses to improve N-use efficiency, since the most economical way to feed livestock is forage plants where its potential biomass production is not well explored. The BMPs basically follow three management practices: (1) soil nutrient availability and forage requirement, (2) fertilizer application, and (3) decrease in nutrient losses from soil. In order to take a decision on applying N-fertilizer to accomplish forage grasses production with social, economic, and environmental benefits, the N-fertilizer use in forage grasses is going to follow the "Right rate, Right source, Right place, and Right time (4R) nutrient stewardship." The application of the 4R's nutrients stewardship is directly associated with economic, social, and environmental impact. The capacity of the 4R's implementation worldwide turns into a best guide to improve the striving of better N-use efficiency in forage grass. The 4R's are interrelated; thus, the recommendation of N-fertilizer rates cannot be prescribed without the combination of the 4R's where a whole system to be followed should be considered to decide about N-fertilizer in pasture. Consequently, any decision in one of the 4R's is going to affect the expected N-fertilizer results and dry matter production.
