“…Hence, cattle dung contributes to localised, high intensity inputs of nutrients including P [33,34]. The overall P contribution and speciation from cattle faeces varies depending on a number of factors including water regime [35] and weather/seasonal conditions [36]. To minimise possible effects on the results obtained in this study, areas with excreted wastes were carefully avoided during soil sampling, and large number of soil cores (200+) were bulked to minimise contribution from animal excretions.…”

Abstract:The influence of soil type and management practices on P distribution in soils from Australian dairy and beef rearing pastoral systems has been investigated by chemical measurements and phosphorus-31 ( 31 P) nuclear magnetic resonance (NMR) spectroscopy. The amount and forms of P within the soil profile varied with soil type, with the acidic red Ferrosols containing relatively high orthophosphate concentrations, averaging 72.2% compared with 66.8% for Dermosols, under similar management conditions. Soil from Sodosol sites which received less fertiliser P addition had the lowest orthophosphate concentration with only 57.6%. In contrast, relatively high proportions of organic P were found in soil samples from unfertilised Sodosol sites. On average, soil from Sodosol sites contained 37.5% organic P (combined monoester P and diester P), while those from Dermosol and Ferrosol sites contained 31.7% and 25.8%, respectively. Of these, the highest monoester phosphate proportions of 44.6% (site M3) and 46.4% (site M4) were found in Sodosol sites with no recent P inputs, but the highest proportion of diester phosphate (5.7%) was found in an unclassified grey sandy loam Dermosol. The higher organic P concentrations in soil from Sodosol sites may be associated with more regular moisture input from both rainfall and boarder-check (flood) irrigation. The highest level of pyrophosphate (8.5%) was also found in a grey/yellow Sodosol. Overall, the results indicate that P speciation in the Australian soils is strongly influenced by soil type, fertiliser P application rate and timing, and moisture variations.

“…Significant physical and chemical changes occur within short periods of time (Dickinson & Craig, 1990). These changes result from the activity of the various organisms that colonize animal dung, including bacteria, protozoa, fungi, nematodes, arachnids, insects and earthworms, as well as local weather conditions.…”

abstract. Piles of fresh cow and horse dung were placed in a pasture in Dziarny in north-east Poland. The differences between the beetle communities colonizing both types of dung at various stages of succession were analyzed. Beetles were sampled 2, 5, 10, 15, 20 and 25 days after placing the piles of dung in the pasture. A total of 5 343 individuals belonging to 125 species and 10 families were collected in 24 samples. None of the species of beetles collected colonized exclusively one type of dung. Several taxa showed a clear preference for cow or horse dung. Beetle succession proceeded faster in horse dung and there were significant differences in the dominant species recorded in the two types of dung. The reasons for the reported patterns are discussed.

“…A fresh pat contains high nutrient contents, such as 1040 kg N ha À1 , 400 kg K ha À1 , 280 kg P ha À1 and 100 kg S ha À1 (Haynes and Williams, 1993). A cattle dung pat is completely decomposed in a time span from a few weeks to several years, depending on water content, climatic conditions, season and activity of the soil fauna (Marsh and Campling, 1970;Dickinson and Craig, 1990). Dung deposition has an important effect on the chemical status of the Cattle activity greatly influences plant species composition and biomass production of grassland ecosystems.…”

International audienceCattle activity greatly influences plant species composition and biomass production of grassland ecosystems. Dung deposition by cattle together with grazing and trampling can be considered as one of the important factors driving vegetation dynamics in pastures. The objective of this study was to investigate at 10-cm and 1-month resolution the plant community dynamics induced by dung deposition in two plant communities (a mesotrophic and an oligotrophic grassland) in a pasture of the Swiss Jura Mountains. Vegetation was sampled four or three times during the vegetation period in contiguous 10 cm x 10 cm quadrats from the centre of the dung pat to a distance of 60 cm. A lower grazing intensity near the dung pat was recorded for all observation periods. In the mesotrophic grassland the canopy was higher near the dung pat already one week after dung deposition. Vegetation around dung pats was submitted to two opposite fertilizing and grazing gradients, which induced changes in vegetation texture and structure at fine scale and short term. We observed a positive rank correlation between species turnover and distance to the dung for both communities, suggesting a seasonal stabilizing effect of dung on the plant composition of their direct surroundings (0–10 cm) likely due to cattle avoidance. Since dung pats are dropped every year in different locations, they create in the pasture a shifting mosaic of nutrient availability and grazing intensity inducing at seasonal scale microsuccessions in plant communities
