| dc.description.abstract | Increasing use of animal manures in Saskatchewan requires information on the effect of manure addition on soil K availability. To address this issue, we examined the effects of repeated application of liquid and solid manure at low and high rates on extractable potassium in soils from four different long-term field trials in Saskatchewan and on K uptake by plants growing on the soils. After four to seven years of manure application, extractable potassium in the soils was significantly increased, with Kelowna extractable K (0-15 cm) increasing from 500 - 600 kg K ha-1 to over 1,000 kg K ha-1 at medium to high rates of annual addition (6,000 - 10,000 gpa swine manure and 15 -30 T ha-1 cattle manure). The K concentration and uptake by the cereal crops was also increased. | en_US |
