The effect of repeated manure applications on chemical and physical properties of upper horizons in clay soils were verified. Samples were take on the 0 – 120 cm of Osborne, Red River and Marquette clays in 12 locations in the Red River Valley region of Manitoba. Samples were done on soils that had received 5 to 30 manure applications they were compared to similar soils that did not received manure. Changes in the chemical properties were observed in the soils that received manure. The soils that received manure showed a potential for salts accumulation in the surface horizons of clay soils (0-15cm) as average electrical conductivity and chloride concentration were higher. Also for the same soil depth, the pH was lower and the average organic matter was higher for the soil that received manure. For all depth studied, the average nitrate- nitrogen and phosphate- phosphorus and potassium concentration measured were higher where manure was applied. No real evidence of sodification could be observed. The differences measured for higher sodium and exchangeable sodium percentage levels in the 0 – 15 cm depth on the soils that received manure were not statistically significant.<\/p>\n
The effect of manure application on clay soils in Manitoba showed changes in the soil properties. The soils’ salinity was not changed significantly for the manure application levels of this experiment. For soils that have high salinity levels, feed rations given to hog should be tested to make sure that the sodium and chloride levels do not exceed the recommended levels. As the manure application levels exceeded the nitrogen requirements of plants on several of the fields nitrate leaching could be observed at 120 cm. Appropriate application rate would reduce nitrate leaching and also lower the salinity potential (lower electrical conductivity and chloride levels in the upper soils’ layers).<\/p>\n","protected":false},"excerpt":{"rendered":"
