THE INFLUENCE OF THE APPLICATION OF BARLEY, WHEAT AND RAPE STRAW ASH INTO SANDY SOIL ON THE CHANGES OF SOIL REACTION AND THE CONTENT OF AVAILABLE PHOSPHORUS, POTASSIUM AND MAGNESIUM
Journal Title: Acta Scientiarum Polonorum – Agricultura - Year 2017, Vol 16, Issue 3
Abstract
Background. Combustion of agricultural crop biomass results in generation of furnace waste that may be used in agriculture. The aim of this study was to determine changes in pH and the content of available phosphorus, potassium and magnesium in soil under the influence of varied doses of ash from barley, wheat and rape straw. Material and methods. In 2010-2011 a two-factorial pot experiment was carried out at the Research Station at Mochełek, established in a completely randomized design with four replications. The first factor was the type of ash from the burnt straw of: barley, wheat, rape. The other factor was the dose of applied ash: 0.08; 0.17; 0.25; 0.34; 0.67; 1.34; 2.68 g∙kg-1 of soil. Results. Applying ash from the straw of cereals and rape into soil caused a systematic increase in pH value in line with the applied dose of ash. As compared with the control treatment (pH – 6.6) the application of dry ash obtained from cereal and rape straw in a dose of 2.68 g∙kg-1 increased the pH value of soil to a level of 7.7-7.8. The use of straw ash in a dose of 2.68 g∙kg-1 of soil significantly increased the content of available phosphorus, potassium and magnesium by 63%, 483% and 93.3%, respectively. Conclusion. Ash from burnt barley, wheat and rape straw can act as a soil fertilizer. Its application causes deacidification of soil and an increase in the quantity of phosphorus, potassium and magnesium in forms available for plants.
