“…Despite the alkaline nature of residue sand and its low initial organic C content, the increase in Zn extractability with increasing rate of compost addition was similar to that reported by several researchers (Hue et al 1988;Cabral et al 1998;Brofas et al 2000). Addition of commercial compost increased DTPA Zn more than piggery and biosolid mix which is not surprising considering the greater amounts of Zn added through commercial composts (7.0-28.9 kg Zn ha −1 ).…”

Purpose Re-vegetation is the preferred long-term practice for managing Alcoa's bauxite-processing residue storage areas. Residue sand is the primary growth medium for rehabilitation; however, it is largely nutrient deficient. Although addition of organic and inorganic amendments can provide short-term supply of plant-available nutrients, but quickly exhausted, thus long-term deficiencies are often observed. The rapid transformation of added zinc into nonavailable pools is predicted as the main factor limiting vegetation performance. Materials and methods Two laboratory investigations were carried out to assess the effect of organic (composts) and inorganic (various types of red mud) amendments on Zn availability in residue sand. Three compost mixtures (piggery, biosolid and commercial compost), three rates of application (0, 10 and 50 t ha −1 ) were taken as organic amendments and incubated with residue sand for 30 days to examine the effects of compost on Zn availability. Seven column treatments were set up as: control residue sand, homogeneous mixtures of residue sand with 3% (w/w) and 8% (w/w) seawater-washed, carbonated or unaltered red mud with residue sand. Leaching with distilled water was carried out every 3 days by adding 1/6th pore volume and analysed for Zn availability and its distribution in various chemical pools. Results and discussion Fractionation studies found that Zn availability decreased with incubation time and red mud amendments. Residue pH and organic C were the major factors controlling Zn availability and its distribution. Column studies showed limited Zn mobility in residue sand even after three pore volumes of drainage. Increased DTPA extractable Zn in surface layers of residue sand with and without red mud amendments after leaching was found and attributed to decrease in residue water-soluble alkalinity. Addition of commercial compost (50 t ha −1 ) increased DTPA Zn, decreased the alkalinity and increased C content in residue sand. The red mud amendments had contrasting effects on Zn that were related to pH of the materials. Addition of seawater-washed red mud increased DTPA Zn in residue sand whereas unaltered red mud decreased DTPA Zn. Conclusions Plant available Zn extracted with 50 t ha −1 of commercial composts addition was well above deficient range, suggesting that they could be an effective Zn source for vegetation establishment. Zinc occurred predominantly in organically bound form in compostamended sand and as carbonate-bound form in leached red mud-amended columns, but the longer term effects of these Zn forms on the release of Zn for plant growth remain unclear.

A number of feed additives, such as As, Co, Cu, Fe, Mn, Zn, and Se are added to enhance pig growth and performance, but most of these micronutrients pass directly through the animal, which leads to elevated levels in the manure. An accumulation of P and trace elements, especially Zn and Cu, typically occurs with repeated swine manure application on soil. The potential environmental hazard associated with the loading of these elements in amended soils could actually be a positive fact in calcareous soils that usually show a high deficiency in available micronutrients. In this experiment, we analyzed the effect of the application of the solid phase of pig slurry to agricultural calcareous soils on the input and availability of Fe, Mn, Cu, and Zn. The experimental design was based on a field experiment using, as fertilizers two manures derived from the solid phase of pig slurry (composted, [C] and noncomposted [NC]). Two application rates were established to supply to the soils 300 and 450 kg N ha 21 , respectively, using a nonamended soil as a control. Soil samples were taken at 0, 14, 33, 53, 73, and 103 days. Available Fe, Cu, Mn, and Zn were extracted with DTPA (0.005 M DTPA, 0.01 N CaCl 2 , and 0.1 N TEA at pH 7) and determined by using atomic absorption spectrophotometry. A significant effect of manure application on available Fe, Cu, Mn, and Zn was observed. Zn and, to a lesser degree, Fe DTPA contents in amended soils were increased by composted and noncomposted pig manure, and Mn was increased by the noncomposted material.

“…The contents of Cu and Zn from the applied slurry or slurry fractions were compared with the amount removed by the harvested crops. As regards the removal of Cu and Zn with harvested wheat and maize, the following rationale was used: irrespective of the manure application rate, c. 0•01-0•12 kg Cu/ha can be removed in the grain of wheat plants and 0•02-0•10 kg Cu/ha with the wheat straw (Cabral et al 1998). Harvesting of maize grain and straw may remove 0•03-0•06 kg Cu/ha, based on the Cu concentrations in the whole maize plant grown on soil amended with pig manure (Berenguer et al 2008).…”

“…The amount of Zn removed from wheat grain and straw is 0•05-0•16 and 0•10-0•37 kg Zn/ha, respectively, for pig manure application rates between 5 and 25 t/ha (Cabral et al 1998). Based on a Zn content of between 13•4 and 17•5 mg Zn/kg in maize biomass (Berenguer et al 2008), 0•30-0•47 kg Zn/ha can be removed from the whole maize plant at pig manure application rates of 29-51 t/ha.…”

Pig slurry characteristics, nutrient balance and biogas production as affected by separation and acidification

et al. 2014

Animal slurry is separated in order to avoid excessive nitrogen, phosphorus and potassium (NPK) fertilization of crops in the field. To enhance fertilizer efficiency further, slurry and its separation products may be acidified, for instance in animal houses. The current study quantified the effects of these treatments, both individually and in combination, on fertilizer efficiency, energy production and heavy metal accumulation as a result of manure management. Acidification increased the availability of N to plants in the manure applied, and provided a better match between plant-available NPK in the manure and separation fraction applied to fields and crop need. Total biogas production was not affected by separation, whereas acidification reduced biogas production because the process was inhibited by a low pH and a high sulphur concentration. The amount of copper applied per hectare in the liquid manure to the wheat field was lower than the amount taken up and more zink and copper was applied in the solid fraction to maize field than taken up. The transportation and field application of solids and liquids did not increase management costs when compared to the transportation of slurry alone, but the investment and running costs of separators and manure acidification increased overall management costs.
