## 3 Results and Discussion
The highest uptake of cadmium, copper, nickel, chromium, nickel and lead was found between the 1 st and 3 rd doses of granulate II used: 46.1%, 53.8%, 55.5%, 73.7%, 84.1% and 114.3%, respectively. A seeds took up significantly more heavy metals from objects fertilised with granulates compared to the control (Table 8). As a rule, granulates II and IV, with a higher share of industrial sludge (respectively 40% and 50%), caused a significantly higher uptake of heavy metals by the grain of the test plant than granulates I (30% industrial sludge) and III (20% industrial sludge), with a higher share of ash. The differentiation of the effect of granulated fertilizers II and IV on the uptake of chromium and zinc by spring triticale grain were significant. Similarly, granulates I and III significantly differed in the uptake of cadmium, copper, chromium, nickel, lead, and zinc by the grain of the analysed plants. \begin{table}

Table 7: Uptake of Cd, Cu, Cr, Ni, Pb and Zn in rape seeds (in mg kg\({}^{-1}\) DM) to pot under the effect of sludge-ash granulates. The increase in granulates doses significantly increased the uptake of cadmium, copper, chromium, nickel, lead and zinc by spring triticale grain (Table 8). The second dose of granulate III did not cause significant changes in the intake of heavy metals. The third dose of granulate II did not cause a significant increase in the uptake of copper, cadmium and lead by triticale grain and of copper granulate IV in comparison to the second dose applied. The highest uptake of zinc, copper, lead, chromium, cadmium, nickel, and by triticale grain was obtained between the 1 st and 3 rd doses of granulate II (40% industrial sludge) applied, with values of 45.4%, 49.8%, 50.0%, 57.1%, 58.6% and 76.6%, respectively. The application of granulate I (30% industrial sludge) between the 1 st and 2 nd doses resulted in higher cadmium intake by 34.0%, copper intake by 16.6%, chromium intake by 44.4%, nickel intake by 34.9%, lead intake by 32.5%, and zinc intake by 27.6%.
