Theme 04: Soil Fertility and Plant Nutrition
Description
The effects of dairy cow manure on soil fertility were investigated at the site of the long-term phosphorus rate by stocking rate farmlet experiment at the Dairy Research Institute, Ellinbank, in Victoria. Manure increased extractable soil P (Olsen) in the 0 - 5 cm layer after 60 days to 61 mg/kg compared with values of 32 mg/kg in the control soils. Extractable soil K (Colwell) almost doubled under manure pads to 5 cm depth from 642 mg/kg in control soils to 1226 mg/kg in manure treated soils. The effects of grazing management on nutrient redistribution and pasture growth within strip-grazed paddocks was also investigated. While soil Olsen P was not different, Colwell K (p < 0.001) and pasture height (p < 0.01) were significantly greater at the front or gate-end of the paddocks compared with the back.
