Influence of liming and fertilization on lowbush blueberry in harvested peat field condition

摘要: Abstract The objectives of the study were to determine: (a) if addition lime reduces peat soil acidity a suitable level for lowbush blueberry ( Vaccinium angustifolium Ait.) plant growth and yield formation; (b) fertilizer rates used create favourable conditions on soil; (c) nutrients uptake will be sufficient in changed conditions. experiment was set up early spring 2000 harvested field Tartu region, South Estonia (58° 22′N, 26° 43′E). type experimental area is Fibric – Dystric Histosol . In complex limestone powder used. use mineral increased plants significantly. Liming reduced but decreased vegetative weed numbers. given strongest bushes developed with pH KCl 2.5–2.7. General recommendations are fertilize blueberries fields every year small amount secure stabile annual productivity plants. plantations one should careful limestone.
