The investigations on the study of nutrition elements takeaway with apple trees removal wood on clonal rootstocks depending on the trees location schemes were carried out within 2005-2007 in the orchards of 1994 and 1996 planting years in the conditions of the Republic of Belarus. Quality composition of infectious diseases of fruit crops on fresh cuttings and fractured branches was studied within 2009-2010. It has been determined that 4.6-5.9 kg of azote, 0.7-1.1 kg of phosphor and 2.0-3.1 kg of potassium are removed depending on plantation construction and age during the pruning with one ton of branches cut, i.e. annually from one hectare of fruit plantation 12-27 kg of azote, 3-11 kg of phosphor and 6-14 kg of potassium are removed. It is for the first time when the quality composition is studied of infectious diseases of fruit crops on freshly cut, old and fractured (chipped wood) branches which have been composted for 1 or 2 years. It was determined that for mulching of near wellbore zone of young orchards it is better to use fractured branches (chipped wood) composted for not less than 1 year. Due to high content of organic and mineral substances in wood waste, their application as fertilization is the additional source of these substances renewal and improvement of soil nutrition regime.
