Influence of surface‐applied poultry manure on topsoil and subsoil acidity and salinity: A leaching column study

It has been suggested that surface applications of animal manure can ameliorate both top and subsoil acidity. For that reason, the effects of surface incorporation (0–5 cm) of a high rate of poultry manure to an acid soil on pH and exchangeable and soluble Al in the top‐ and subsoil were investigated in a leaching column study. During the experimental period of 108 d, columns received a total of 875 mm with leaching events occurring after 9, 37, 58, and 86 d. Incorporation of poultry manure into the surface 5 cm resulted in a large rise in pH measured in both 1M KCl and in soil solution. This liming effect was attributed primarily to the substantial CaCO₃ content of poultry manure. In the 15–45 cm layer, pH_KCl was not significantly different between poultry manure and control treatments but surprisingly, soil‐solution pH was substantially less in the poultry‐manure treatments. Exchangeable Al was significantly less in poultry manure than in control in all soil layers although the effect was most marked in the 0–5 cm layer. However, although concentrations and activities of monomeric Al (Al_mono), and the proportion of total Al present as Al_mono, in soil solution were lower under poultry manure than in control in the 0–5 cm layer, the reverse was, in fact, the case in lower soil horizons. This was attributed to a soluble‐salt effect, originating from the large cation content of poultry manure, displacing exchangeable Al³⁺ and H⁺ back into soil solution. Indeed, electrical conductivity and concentrations of Ca²⁺, Mg²⁺_, K⁺, and Na⁺ in soil solution were substantially higher in the poultry‐manure than in the control treatments at all soil depths. Poultry‐manure applications also resulted in substantial increases in the concentrations of Ca²⁺_, Mg²⁺_, K⁺, Na⁺, Al_mono, NH , and NO in leachates, particularly at the fourth leaching. It was concluded that although surface application of poultry manure can raise soil pH in the topsoil, increases in soluble‐salt concentrations in soil solution can greatly modify this effect in the subsoil.  相似文献

The purpose of this experiment was to estimate the influence of nonspecific immunostimulation of pregnant sows on the immunological value of colostrum. The studies were done in the fall-winter season on 20 pregnant sows (Polish Landrace) divided into four groups, five animals each. The sows were clinically healthy and unvaccinated. Group I received isoprinosine, group II (TFX), group III (HMB), and group IV served a control. The immunostimulants were applicated 4-6 weeks before the expected date of delivery. The following parameters were determined in colostrum taken from sows after completed delivery: specific gravidity; total proteins, lysozyme activity, IgG level. It was found that the nonspecific immunostimulation of pregnant sows increased in colostrum the level of IgG, total protein content and lysozyme activity.  相似文献

Evaluation of the specificity of Pasteurella multocida somatic antigen-typing antisera prepared in chickens, using ribosome-lipopolysaccharide complexes as inocula   总被引：2，自引：0，他引：2

Purified lipopolysaccharides (LPS) from 16 serotypes of Pasteurella multocida were complexed with Aspergillus fumigatus ribosomes. The complexes were used as inocula to prepare antisera, in chickens, for somatic antigen typing by the gel diffusion precipitin test (GDPT). Antisera made against 15 of 16 LPS reacted with their respective specific heat-stable antigens in the GDPT and homologous LPS in the passive hemagglutination test. Antisera could not be made against serotype 15 LPS. Correlation was not observed between intensity of the precipitin reaction in the GDPT and titer to homologous LPS in the passive hemagglutination test. Most antisera cross-reacted with other heat-stable antigens of other serotypes in the GDPT. Many of these cross-reactions were eliminated by dilution. Cross-reactions that occurred in the GDPT with antisera made against LPS of serotypes 2, 5, 7, and 8 could not be eliminated by dilution.  相似文献
