Soil in apple rootstock stool-beds contained more organic matter, phosphorus, potassium, magnesium and total nitrogen than that in the nearby bare land (control field). These differences were evident mainly in the superficial soil layers and were significant only in some cases. Similarly, more of the examined elements (except for magnesium) were found in the soil between the rows of plants within the stool-beds than in the rows of rootstocks. The increase in total copper level in the soil used in stool-beds was observed over some consecutive years as a result of the use of rootstock defoliation compounds containing copper. Yet this Cu increase was not significant and it occurred in the soil layer 0-25 cm, deep. Significantly more copper was found in the soil taken from between the plant rows in stool-bed than from the stools beds.
