“…Soil strength tends to increase with decreasing soil organic matter concentrations because soil organic matter serves as an organic aggregate binding and bonding material (Munkholm et al, 2002). The relatively lower moisture content and available water holding capacity of the RAKE-IF treatment is consistent with its lower soil organic matter content because organic matter fosters soil moisture retention (Plaza et al, 2004;Powers et al, 2005). There were no differences in soil organic matter among treatments in the SILVO, SWITCH, LA-FORvsPAST, and AR-FORvsPAST studies (Blazier et al, 2008a;Liechty et al, 2009), in which litter was not removed.…”

“…Inorganic fertilizers do not replenish organic matter essential as microbial substrates and may exacerbate soil microbial biomass and activity declines caused by organic matter removal (Blazier et al, 2005). In contrast, fertilization with poultry litter can increase soil microbial biomass and activity (Canali et al, 2004;Plaza et al, 2004). Soil organic matter also in part determines soil water availability and temperature (Attiwill & Adams, 1993), and poultry litter has been shown to increase soil water content and available water holding capacity and reduce soil temperature (Agbede et al, 2010;Warren & Fonteno, 1993).…”

“…Balota et al (2012) observed increases in the soil organic C and MBC with the application of SWW on a clayey soil under conventional tillage (CT) or no tillage (NT). Increases in MBC with the application of pig slurry up to 150 m 3 ha -1 year -1 in a Typic Haploxeralf were also observed by Plaza et al (2004). The application of SWW to a clayey-sandy soil increased the number of aerobic heterotrophic bacteria by 1.3 (Suresh et al, 2009).…”

We evaluated the effects of biannual surface applications of swine wastewater (SWW) for 11 years, on chemical and microbiological attributes of a clay-textured soil under no-tillage (NT) or conventional tillage (CT) in Palotina, Paraná, Brazil. The treatments consisted of SWW doses (split into autumn-winter/spring-summer seasons) totaling 30, 60, 90 or 120 m 3 ha -1 year -1 , and a control without application, under CT or NT soil managements (SM). The experimental design was in randomized blocks with a split-plot arrangement and four replications, with SM in the plots and the doses of SWW in the subplots. After 11 years of applications of SWW, soil samples were taken at 0-10, 10-20, 20-40, and 40-60 cm of depth by the end of the winter cover crop, 44 days after the second biannual application. The treatments had only minor effects on the assessed chemical and microbiological soil properties. Available P and NO 3 --N increased with the doses of SWW at the two upper soil layers, whereas NT decreased NO 3 --N at 10-20 cm and increased P at 0-10 cm. Zn 2+ also increased with the doses of SWW, irrespectively the SM. NT increased the microbial biomass C (MBC) at 0-10 cm and 10-20 cm of soil depth, and the microbial quotient (qMic) at 0-10 cm. SM and SWW did not change the densities of heterotrophic bacteria, fungi, nitrite-oxidizers or ammonifiers at any soil depth. SM had single effects on organic C, MBC and qMic, whereas SWW had single effect only on Zn 2+ . Only available P and NO 3 --N were affected by both SM and SWW. The principal component analysis for chemical and microbiological attributes showed distinct groupings between CT and NT, and SWW rates at 0-10 cm and 10-20 cm of soil depths, the most influenced soil layers.

The aim of bacteriological examinations was to evaluate soil and manure taken from dairy farms at different times and sampling sites. The study was conducted from September to October. Soil samples were collected directly at the wall of the barn (GI) and at distances of 15 m (GII) and 45 m (GIII) from the livestock facilities. Manure was collected inside the building, at the entrance (KI) and at 1/4 (KII) and ½ (KIII) of its length. Air temperature, relative humidity and the moisture content of the samples were recorded at the sampling sites. The soil and manure samples were subjected to quantitative and qualitative bacteriological examinations conducted in accordance with Polish Standards. Statistical analysis of the results was performed by a one-way analysis of variance and Duncan’s multiple comparison test. The highest number of bacteria in the soil was found at the wall of the barn. Most mesophilic bacteria, actinomycetes, coliforms and E. coli were found in late April and early May, most psychrophilic microorganisms in June, and most proteolytic bacteria at the end of December and in early January. The microbiological contamination of the soil was low (coli titer ≤0.01), amounting to 0.001, and it was detected only at the wall of the barn. The qualitative study of soil revealed only E. coli bacteria. The highest number of microbes in manure was found in samples from the middle of the barn (KIII) taken at the end of April and at the beginning May. Out of the bacteria examined in this study, E. coli and Enterobacter spp. were found in manure samples throughout the study period. While analyzing the impact of selected parameters, such as microclimate and humidity, on manure samples tested for bacteria, a correlation was observed between the presence of all microbes and sample moisture. The bacterial contamination of soil and manure was the biggest during the spring period, which was probably due to climatic and microclimatic conditions. However, the contamination was negligible owing to the absence of pathogenic bacteria and a high soil index. This proved that proper zoohygienic conditions were maintained on the farm.
