“…Water-holding capacity and water absorption rate of litter are related to litter characteristics and reserves. Dunlop et al state that the decomposition degree of litter in larch and mixed forest stands was higher than that in other forests [35]. The thickness and decomposition degree of litter are the main factors that determine the water absorption capacity of litter [36,37].…”

Water conservation is an important function of forest ecosystems, but it is still unclear which forest types function best in this regard. We investigated the water conservation function indicators including the water-holding rate of branches and leaves (BL wr ), water-holding capacity of litter (L wc ), water absorption rate of litter (L wr ), soil infiltration rate (I r ), soil and water content (SWC), soil water storage (SWS), and soil organic matter (SOM) accumulation of five forest types (Larix gmelinii forests, Pinus koraiensis forests, Robinia pseudoacacia forests, Pinus tabulaeformis forests, and mixed forests) and evaluated them using the gray correlation method (GCM). The results indicate that the BLwr of five stands in the study area varied from 18.3% to 33.5%. The SWC and SWS of the R. pseudoacacia stand were 13.76% and 178.9 mm, respectively, which was significantly higher than that of the other stands (p < 0.05). The SOM was similar for the R. pseudoacacia (0.23%), mixed forest (0.22%), and L. gmelinii (0.22%) sites. The BL wr , L wc , L wr , SWC, and SWS values of broad-leaved tree species were higher than those of the mixed species, followed by those for coniferous tree species. Soil infiltration rate followed the order L. gmelinii > P. koraiensis > mixed forest > P. tabulaeformis > R. pseudoacacia. Based on our results, the R. pseudoacacia stand had the highest water conservation ability, while the lowest performance was found for the P. tabuliformis site. This suggests that, in order to enhance the water conservation function of forests in northeastern China, the focus should be on the establishment of R. pseudoacacia forests.Sustainability 2019, 11, 4075 2 of 13 scale of small watersheds, albeit with complex calculations [16,17]. The Gray correlation method is widely used as a relatively simple and reliable analysis method [18]. The results of this method are accurate and can be used to analyze the development trend of a system. In addition, there is no requirement in terms of sample number, and a typical distribution law is not needed because the amount of calculations is relatively low [19][20][21].The mountainous area of Eastern Liaoning is a typical seasonal dry area in China. Precipitation is unevenly distributed (about 70% of precipitation occurs in June-September), with serious water shortage [22]. Against the background of a warming climate, these water shortages will be aggravated, restricting the water conservation function of vegetation in this area [22]. Only by adapting to this arid environment, plants can maintain their ecological benefits and functions. Larix gmelinii, Pinus koraiensis, Robinia pseudoacacia, Pinus tabulaeformis, and mixed forests are widely distributed in the eastern Liaoning Mountains [22]. After long-term natural selection and co-evolution, they have shown a strong ecological adaptability. However, we do not know which forest type has the highest water conservation capacity, making it necessary to compare these forests, incorporating global climate change data....

“…Results showed that fresh dairy manure gave the highest net increase in resin-P and labile-P fractions in terms of percentage of total P added, poultry litter compost was most efficient at increasing inorganic P, and fresh dairy manure, poultry litter, vegetable residue, and sheep manure composts increased labile P fractions the most. Tsegaye et al (2003) studied the effects of fresh and composted poultry litter and urea fertilizer on soil properties. There was potential for groundwater contamination with all treatments; urea and fresh poultry litter had comparable risks and composted litter had a reduced risk.…”

The following review provides a summary of research activities related to the characterization, treatment, and management of agricultural wastes. The review has been divided into four major sections: (i) Waste Characterization, Analytical Methods and Measurement, (ii) Agricultural Waste Treatment, (iii) Reuse and Recycling of Agricultural Wastes, and (iv) Pollution Prevention and Minimization of the Environmental Impact of Agricultural Wastes. WASTE CHARACTERIZATION, ANALYTICAL METHODS AND MEASUREMENT Physical:Olive press cake (OPC) was composted with water and olive mill wastewater (OMW) over several temperatures (17ºC to 63ºC) and the metabolic activity and the respiration profile was monitored. Mari et al. (2003) proposed that composting OPC with OMW would have a two-fold benefit: compost of the solid waste would occur, and decomposition and detoxification of the wastewater would occur. More microbial activity was observed when OPC was composted with OMW than with water, and it was observed a temperature of 48.5ºC provided a better representation of the respiration profile on average. Biological: Inglis and Kalischuk (2003) studied the potential for direct identification of Campylobacter spp. in bovine feces using PCR, without the need 1480 for an enrichment step. Common measurement techniques require counting of colonies by technicians which introduces human error, while the PCR method can be influenced by PCR inhibitors found in feces, causing false-negative results. When inhibitors were removed before analysis, it was believed that the PCR method is more robust and allows for the detection of generally more species of Campylobacter. An intensive agricultural region in southern Alberta was studied over 2 years by Johnson et al. (2003) for the presence of Escherichia coli (E. coli) O157:H7 and Salmonella spp. in the watershed. E. coli O157:H7 was detected in 0.9% of surface water samples and Salmonella spp.was detected in 6.2% of the surface water samples. A statistical model did notshow an association between predicted manure output and pathogen occurrence, highlighting the need to include geographical and weather parameters into an analysis.A method for characterizing changes in a microbial community during the composting process was presented by Schloss et al. (2003). Automated ribosomal intergenic spacer amplification (ARISA) analysis was performed before and during composting, and it was found that the microbial community during composting did not represent the microbial community in the wastewater. The ARISA analysis provided a relationship between the variability in traditional compost variables (temperature, pH, effluent gas) and the composition of the microbial community. 1481 studies on the enterococcal flora from 6 faeces-containing samples. A phenotypic testing technique known as PhenePlate was used to discern enterococcal population diversity. This method provides a tool for determining the origins of faecal contamination. Gas/Volatile Emissions: Methane emissions were measured in a model storage...
