Original Abstract

Controlled-release fertilizers based on superabsorbents containing lignohumate and conventional mineral fertilizer (NPK) were prepared. Their water absorption was supported by the presence of lignohumate (LH) and suppressed by the presence of NPK. The release of mineral nutrients was prolonged up to four weeks in the case of increased content of NPK. The addition of LH had negligible influence on the release of P and N. The release of LH was partially suppressed by the higher content of NPK. The release of nutrients from all used samples was connected with the strong increase in conductivity and weak increase in pH values. The application of superabsorbents supported growth of corn. The length of roots was probably more influenced by better water management, while the growth of above-ground plant was more affected by release of nutrients.
