| Abstract:
Experiment was conducted on different types of soils. Samples from particular genetic horizons of soil were taken at four different locations where the highbush blueberry were growing and some chemical analyses were made. It was discovered that the best growth of blueberries occured on podzolic and mucky soil developed from sand. Growth did not occur or was very weak on neutral-alkaline soil of sandy black earth and mucky low peat. This investigation showed that soil reaction is highly important factor. In Poland an 'intensive investigation concerning the properties of the highbush blueberry introduction has been conducting. The investigation of this plant has indicated that there are many' profitable features. To introduce the blueberry to production someone needs a knowledge of soil requirements and the conditions which influence its growth. Investigations carried out by Kramer and Schrader /1945/ indicate that the highbush blueberry because of its small requirements can grow very well at a low pH. In areas where the amount of basic cations in sorption complexes is low, The authors have the opinion that slow or poor growth of the highbush blueberry is caused by deficit of anions than cations. Ballinger and others /1958/ works showed, that if saturation sorption complex is higher than 10%, growth will be very weak, but with higher saturation with calcium, development of this plant is completely retarded. Darrow /1944/ and Darrow and Moore /1957/ observations indicate that the highbush blueberry in its state grows only on acid soils / pH= 4.3 – 4.8 /, and for this reason productive plants can be grown on soils with similar acidity. This indicates that this plant can grow on crumbly soils, sandy-peat or mucky developed from well moisted sandy areas. Eck /1966/ considers that the highbush blueberry can be cultivated with success on sandy soils with high amounts of humus, that is well aerated and enough moisture content, plus of cause high acidity. | |
