In the years 1999-2001 the role of organic matter, ammonium phosphate, and Captan in alleviating the problem of
replant disease was investigated at the nursery of the Garlica Murowana Experimental Station. After the initial tests which
showed positive effects of drying and steaming soil on the height of ‘Antonówka Zwykła’ seedlings, a field
experiment was established. The results showed that peat, humus, and dried cow dung positively affected the diameter
of trees in the nursery. The organic fertilization also induced an increase in the number of shoots and their
total length. No positive effect of ammonium phosphate was determined neither the application of Captan improved
the growth of trees in the nursery.
