“…Ihnat and Fernandes (1996) found an increase in total Mn of 47 to 59% for straw/poultry manure compost mixtures over 78Á86 d of composting. In our study, Cd showed significant increases in compost compared with fresh manure at all four feedlots (Fig.…”

Interest in composting as a means of handling the large volumes of manure generated by southern Alberta beef cattle feedlots has increased in recent years. We measured concentrations of 19 elements (C, N, P, Na, Ca, Mg, K, S, Al, Fe, Mn, Zn, Cu, Cr, Ni, P b , Co, Mo and Cd) in fresh manure, interim-composted manure and finished compost, at four commercial feedlots. Thirteen elements showed increased concentrations (by 26–73%) with composting, while four (C, Cr, Ni and Mo) showed concentration declines. Of the remaining two, the trend in N concentration was feedlot dependent, while Pb was largely unaffected. Total mass loss during composting averaged 54%, which represents a substantial decrease in haulage requirements. Overall average C losses were 61% and N losses 33%. On an equivalent wet weight basis ("as-is"), composting allowed haulage of 56% more N, 84% more P, 91% more Zn, and 76% more Cu than fresh manure, which is advantageous in terms of moving nutrients and trace elements from high to low-loading areas. Our study quantifies nutrient and trace element behaviour during composting, provides comparative data with fresh manure, and helps tailor end-use decisions (e.g., haulage distance, application rate) on the compost product.

“…Continued disposal of large amounts of raw manure may result in soil and water contamination via leaching of toxic elements, nutrient imbalances and phytotoxicity in crops (Milan and Fernandes, 1996). Composting has become a preferred method for a variety of processing organic byproducts for application as soil conditioners and amendments (Butler et al, 2001).…”

Effect of composting on the extractability of plant nutrients in organic wastes is essential for their recycling in sustainable soil fertility management. Therefore, an experiment was carried out to determine the concentrations of total C, total N, extractable P, K, Na and B in five types of fresh and composted manures (namely buffalo, camel, cow, goat and poultry). Laboratory results showed that the extractability of elements varied considerably with the type of composted manure. Total C varied in the order cow > goat > buffalo > poultry > camel while total N was in the order buffalo > poultry > cow > camel > goat. Total C, total N, extractable K and Na decreased with composting, whereas extractable P and B increased. Goat manure had higher pH and EC values than cow and poultry manures whether in fresh or composted samples. A marked increase in the EC value was observed in composted manures, whereas pH was reduced with composting.

“…Total contents of 10 elements (Ca, Cu, Fe, K, Mg, Mn, Na, Rb, Sr, Zn) were determined in acid digestions of cauliflower tissue by flame atomic absorption spectrometry (Ihnat 1982(Ihnat , 1987(Ihnat , 1988Ihnat and Fernandes 1996;Ihnat et al 2000). The digestion involved an initial treatment of 1.000 9 0.002 g oven-dried, ground (B1 mm) plant material with 10 mL of concentrated, 70% HNO 3 (Trace Metal Grade from Fisher Scientific, Nepean, ON, or double distilled from George Frederick Smith Chemical Co., Columbus, OH) in a 100 mL volumetric flask on a hot plate, followed by 10 mL HNO 3 '5 mL of 70% HClO 4 (double distilled from George Frederick Smith Chemical Co., Columbus, OH).…”

Kowalenko, C. G. and Ihnat, M. 2010. Effects of soil limestone and foliar manganese and zinc applications on field cauliflower growth and element contents. Can. J. Soil Sci. 90: 177Á188. A trial was conducted in a field where a previous study suggested that a deficiency of manganese (Mn) or zinc (Zn) was created by the application of limestone, with the objective to confirm whether lime-induced deficiency is a potential problem in coastal British Columbia acidic soils. The trial involved the application and incorporation of limestone at two rates (9 and 19 Mg ha(1 ) in addition to a control with no limestone, and five foliar applications of Mn and Zn. The foliar applications included a control, Mn at two rates (2.3 and 4.5 kg ha ) and a combination of Mn and Zn, both at 2.3 kg ha 1 . The trial was conducted at the same location over seven growing seasons (1979Á1985), with the cauliflower grown in five of those years. The plot was fallowed in 1981 and 1983. The limestone treatments were applied in the spring of 1979, and again in the summer of 1981, while the foliar applications were applied to the plant each cropped season. Limestone increased plant dry matter yield in three years, decreased it in one, and had no effect in the other. The micronutrient applications did not affect dry matter yield in any of the years. Chemical analyses on the plants showed that limestone increased Ca and decreased Mn and Zn concentrations. The foliar applications increased plant Mn and Zn concentrations. Limestone, but not the micronutrient, applications influenced other element concentrations, with decreased concentrations of potassium, magnesium, sodium, strontium and rubidium. Iron and copper concentrations were not influenced by limestone applications. The decreased concentrations of nutrients could not account for the yield reduction by limestone applications in the one year, since concentrations of the nutrients measured in that year were not significantly different to concentrations in years when yields were increased. Further, basal applications of nutrients (nitrogen, phosphorus, potassium, magnesium and boron) had been applied to ensure that non-treatment nutrients were not deficient. Although monthly weather conditions were similar for one year of increased yield and one year of decreased yield, the influence of weather on the variable response by the crop could not be discounted as there could have been adverse weather conditions at critical stages of plant growth. Strontium and rubidium tended to respond to limestone similar to calcium and potassium, showing that their measurements have potential to further evaluate nutrient dynamics since they have characteristics similar to calcium and potassium, respectively. This field trial showed that limestone applications had many and variable effects on the availability of numerous nutrients and associated elements on cauliflower in addition to Mn and Zn. This showed the high degree of complexity of limestone applications on acidic soils.
