Soil physical properties of a Chernozemic clay loam after 24 years of beef cattle manure application

Abstract

Miller, J. J., Sweetland, N. J. and Chang, C. 2002. Soil physical properties of a Chernozemic clay loam after 24 years of beef cattle manure application. Can. J. Soil Sci. 82: 287-296. Limited information exists on the influence of long-term application of beef cattle manure on soil physical properties in the Canadian prairies. A site on a clay loam soil (Dark Brown Chernozem) at Lethbridge was used to determine the effect of increased rates of manure application on selected soil physical properties in 1997 and 1998. The manure (from an unpaved feedlot) was applied annually in the fall for 24 yr at one, two and three times the 1973 recommended rates under dryland (0, 30, 60, 90 Mg ha -1 wet basis) and irrigation (0, 60, 120, 180 Mg ha -1 ). There was a significant (P < 0.05) decrease in the sand content of soil (0-10, 10-20 cm) with increased rates of manure application; and an increase in clay content for the 60 and 120 Mg ha -1 rates compared to the control under irrigation. There was a significant and negative linear relationship between increased rates of manure application and bulk density (0-5, 10-15 cm) for most seasons, and season affected bulk density values for a given manure rate. Penetration resistance (0-14 cm) was unaffected by increased rates of manure application under dryland. Under irrigation, it was significantly reduced at only the 3.5 cm and 10.5 cm depths in 1997, and at only the 3.5 cm depth in 1998. Air permeability was generally unaffected by increased rates of manure application, except for the 0-5 cm depth under irrigation, where it was significantly lowered at the highest application rate. Soil temperatures (0, 10, 20 cm) were lower under increased rates of marnure application at the 10 and 20 cm depths in the spring and summer under dryland, and they were higher at these two depths in the winter. Under irrigation, soil temperatures were lower with increased rates of manure application at the 20-cm depth in the spring, and they were higher at the 20-cm depth in the fall, and at the 0-and 20-cm depths in the winter. Overall, soil physical properties generally had a neutral or positive response to 24 yr of annual manure application at high rates, and should not cause any detrimental effects to the soil's physical condition.

Produção de raízes de mandioca e propriedades química e física do solo em função de adubação com esterco de galinha

“…Com relação às propriedades físicas do solo, a utilização de adubos orgânicos pode incrementar o teor de carbono orgânico (Nyamangara et al 2001, Eghball 2002, Miller et al 2002; melhorar a sua estrutura e reduzir a sua plasticidade e coesão (Pires et al 2008); promover a agregação das partículas (Barbosa et al 2004); reduzir a sua densidade e temperatura e ampliar a porosidade (Bhogal et al 2009, Agbede 2010, promovendo maior capacidade de retenção de água no solo (Nyamangara et al 2001, Pires et al 2008. A ação da matéria orgânica na fí-sica do solo está relacionada à melhor estruturação, com redução na compactação (Zhang et al 1997), aumento na aeração (Oelsen et al 1997) e redução no fendilhamento de solos argilosos (Tejada et al 2008).…”

Influence of tillage and liquid swine manure on productivity of a soybean-barley rotation and some properties of a fine sandy loam in Prince Edward Island

“…These benefits, from manure addition in particular, are often attributed to the enhancement of soil organic matter content (Aoyama et al 1999;Assefa et al 2004;Blair et al 2006). The extent and degree of change in soil properties are dependent on rate of manure application and the number of years of application (Miller et al 2002;Hao et al 2003). However, the type and form of manure (e.g., solid beef manure compared with LSM) can result in differential effects on soil properties (N' Dayegamiye and Côté 1989;Chantigny et al 2001).…”

Soil microbial biomass, functional diversity and crop yields following application of cattle manure, hog manure and inorganic fertilizers

“…Application of manure to farm land increases soil organic matter, which increases nutrient availability (Stevenson et al 1998;Hao and Chang 2002;Mooleki et al 2002) and improves soil physical properties like structure, aeration, drainage and water-holding capacity (Miller et al 2002;Whalen and Chang 2002;Reynolds et al 2003). Mineralization of biodegradable C contained in applied manure also alters soil ecology.…”
