The effectiveness of wood ash in regulation soil pH for field crops and comparison with other liming materials Project leader Agrita Švarta Duration 2022 - 2025 Research focus 3.Studies of the basic resources of the bioeconomy – land, soil, water – to ensure sustainable use and reduce pollution Source of funding Knowledge transfer Description of project The aim of research To demonstrate the effect of wood ash on soil pH, its positive effect on crop yields compared to other liming materials. The tasks of project: Determination of productivity of crop depending on the type of liming materialDetermination of soil agrochemical properties depending on the type of liming materialEconomical evaluation of the using of the liming materials Results 1. Control variant without liming and six variants: Granulated lime 1.13 t ha-1, wood ash – 15 t ha-1, wood ash 30 t ha-1, dolomite flour 7.5 t ha-1, limestone flour 7.5 t ha-1, garden lime 5.9 t ha-1, were tested. The use of wood ash significantly increased winter wheat yield compared to control variant, but the amount of the applied dose did not significantly affect grain yield. In all tested variants, the grains meet the requirements for bread wheat. 2. In both experimental sites, the yield increase of winter wheat in the all limed variant was significant compared to the control variant. In the variants where soil liming was performed, the number of grains per ear was higher than in the control variant. A year after liming, the acidity of the soil in the limed variants decreased compared to the control variant.
