In 2011-2013, research was conducted on the fertilizer value of ash from municipal waste combustion used as an alternative source of phosphorus. A field experiment was set up on light soil. The design included 5 fertilization variants of maize, which was cultivated for grain and fertilized with mineral fertilizers and ash (P1, P2, P3): NK, NPK, NK+P1 (P1−21.80 kg P ha-1), NK+P2 (P2−43.60 kg P ha-1),...
Basil, cultivated as a medicinal and seasoning plant, has strict requirements as to climate, as well as soil fecundity and humidity. The herb harvested during flowering period, contains, besides valuable essential oil, plant dye, vitamins and mineral components. The undertaken studies were aimed at analyzing the contents of macro and microelements in the herbs of two basil cultivars (‘Kasia’ and ‘Wala’),...
The field study was carried out between 2000 and 2003. The plants of Sparaxis tricolor were sprayed twice prior to flowering with a fertilizer called titanium (0.8% Ti) in three concentrations: 0.02, 0.04 and 0.08%. Application of titanium in the concentration of 0.04% increases the total yield of corms by 20% on average and the commercial yield by 7%. Spraying the plants with titanium in the concentration...
