Rośliny, szczególnie warzywa, mają naturalną zdolność do gromadzenia azotanów. W artykule przedstawiono warunki środowiska (gleba, klimat, nasłonecznienie) oraz zabiegi agrotechniczne mogące silnie modyfikować zawartość azotanów w warzywach. Szkodliwość metali ciężkich polega na ich możliwości kumulowania się w organizmach żywych i ich chronicznej toksyczności. Przedstawiono główne źródła skażenia roślin metalami ciężkimi (gleba, opady, ścieki, nawozy). Akumulacja metali ciężkich zachodzi w największym stopniu w liściach, a w najmniejszym w owocach. Ograniczeniu gromadzenia się metali ciężkich w roślinach sprzyja zatem: uprawa w rejonach czystych ekologicznie, uregulowanie odczynu gleby, optymalne nawożenie i prawidłowe zabiegi agrotechniczne.

The results of three-year investigations on cv. Galaxy F1 of cabbage grown commercially in the south Poland, an important agricultural region, are presented. In 2005-2007, a field experiment was carried out on silty clay soil containing 0.91-1.02% organic carbon and of the soil acidity pHH2O 7.18-8.21. Effects of the N form (ammonium sulfate and UAN: a solution of ammonium nitrate + urea) and the method of application (placement and broadcast techniques and complementary foliar fertilization with urea and Supervit K) on the P, K, Mg, Ca and S concentrations in edible parts of cabbage were surveyed. Nitrogen fertilizer was applied at the rate of 120 kg N ha–1. In the placement treatment, fertilizer was applied on each plant while transplanting seedlings in rows 10 cm deep and spaced 10 cm from one another. Foliar nutrition with 2% urea was carried out 3 times and once 1% Supervit K was applied. The content of nutrients in cabbage leaves changed over the years. On average, the highest K and Mg content was in 2006 and the lowest P, K, Mg and Ca content appeared in 2007, with the harvest of 2005 being intermediate. The sulfur leaf content was the highest in 2007 and the lowest in 2006. The concentrations of P, K, and Mg in edible parts of cabbage were less than sufficient. The source of N affected P concentrations in cabbage leaves in 2005-2006. Slightly higher P amounts were detected in cabbage fed UAN than ammonium sulfate. None of the examined factors influenced K and Mg concentration in cabbage. In 2005-2006, slightly lower concentrations of Ca in cabbage fed UAN than ammonium sulfate were noticed. In every year, higher S concentrations in plants fed ammonium sulfate were detected. In 2005-2006, cabbage fertilized with the broadcast technique had slightly higher amount of S than the one given the placement treatment. Foliar fertilization did not affected the content of the examined nutrients in cabbage in any year of the trials.

Iodine is not an essential nutrient for plants. Side-effects of its application on mineral nutrition of plants have not yet been thoroughly documented. The aim of the study was to evaluate the influence of soil application of iodine and sucrose on mineral composition of spinach plants. In 2009–2010, a pot experiment with spinach Spinacia oleracea L. ‘Olbrzym zimowy’ cv. cultivation on mineral soil was carried out in the plastic tunnel. The research included diverse combinations with pre-sowing iodine fertilization (in the form of KI) and soil application of sucrose: 1) –control (without iodine fertilization and sucrose application), 2) –1 mg I dm⁻³ of soil, 3) –2 mg I dm⁻³ of soil, 4) –1 mg I + 1 g sucrose dm⁻³ of soil and 5) –2 mg I + 1 g sucrose dm⁻³ of soil. In spinach samples as well as soil after cultivation the content of: P, K, Mg, Ca, S, Na, B, Cu, Fe, Mn, Mo, Zn, Al, Ba, Cd, Ce, Co, Cr and La was determined using ICP-OES technique, while Cl – using nephelometric method. Iodine synergistically improved the uptake of Mg, Na and Ce as well as Fe (for Fe only in the case of higher iodine doses) while antagonistically affected Cr uptake by spinach plants. After application of iodine in a dose of 2 mg I dm⁻³ soil, higher accumulation of Na, Fe, Zn and Al was observed along with reduced concentration of P, S, Cu and Ba in spinach plants when compared to the control. Simultaneous application of iodine and sucrose (in comparison to the control or plants fertilized only with iodine) contributed to a significant increase in the accumulation of K, S and Mo as well decreased content of Mg, Fe, Ba, Co and La in spinach plants.

The aim of the research was to determine the influence of foliar nutrition with Pentakeep V as well as differentiated nitrogen fertilisation on the content of macro- (Ca, K, Mg, Na, P and S) and micronutrients (B, Cu, Fe, Mn and Zn) in spinach leaves. Pentakepp V is a fertilizer containing 5-aminolevulinic acid (5-ALA), which is the direct precursor of chlorophyll in plants. In 2006-2007, a pot experiment with spinach Spinacia oleracea L. cv. Spinaker F1 was carried out. The plants were cultivated in 60 × 40 × 20 cm containers placed in an open field under a shade-providing fabric. Containers were filled with loamy clay soil (35% of sand, 28% silt, 37% clay) with the organic matter content of 2.44% in 2006 and 2.52% in 2007. The experiment design included 2 sub-blocks: with and without foliar nutrition. The plants were sprayed twice with Pentakeep V fertilizer in a dose of 0.02% w/v (16 ml 100 dm–3 – 3000 dm3 per 1 ha). In each sub-block, soil fertilization with nitrogen was applied: 1 – control (without N fertilization), 2 – 25 mg N dm–3 of the soil (50% of N dose), 3 – 50 mg N dm–3 of the soil (100% of N dose). Nitrogen fertilization was applied in the form of ammonium nitrate prior to seed sowing. Among all of the determined nutrients, a significant interaction between foliar nutrition and soil application of nitrogen was observed in the case of Ca and Fe content in spinach leaves. Foliar application of Pentakeep V decreased the content of Ca in plants without N fertilization as well as increased the amount of this element in plants fertilized with full dose of nitrogen (100% of N dose). These observations were further verified by the changes of Ca content in soil after plant cultivation. Increased uptake of Ca from soil was observed for plants treated with Pentakeep V and fertilized with the full dose of nitrogen. A higher content of this element in soil was noted after cultivation of plants receiving only Pentakeep V (without N fertilization). Specific interaction of Pentakeep V on the increased content of Fe in spinach fertilized with 50% dose of N was observed. In comparison with the control, N fertilization in both doses (regardless of the foliar nutrition) led to the decrease of the plant content of Ca, Na and Fe as well as resulted in the increased concentration of K in spinach leaves. Plants fertilized with half-dose of N were characterized by lower content of Mn but plants treated with 100 % of nitrogen had higher concentration of this element in comparison to the control. Foliar application of Pentakeep V (considered independently of N fertilization) did not significantly influence the content of these nutrients in spinach leaves. Weather conditions throughout both years of cultivation had no effect on the interaction between foliar nutrition with Pentakeep V and N fertilization on the content of analyzed nutrients.

Various forms of nitrogen fertilizer were applied in the cultivation of red cabbage (in the years 2003–2005), ‘Langendijker’ c.v.: control (unfertilized with nitrogen), Ca(NO3)2 , (NH4)2SO4 , NH4NO3 , CO(NH2)2 applied as solid fertilizers. This experiment aimed at determining the influence of various nitrogen forms on the content of Al, B, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Sr, Ti, Zn, V in cabbage heads and the changes in the content of the available form of these elements for plants in soil after cabbage cultivation. The heads of plants fertilized with calcium nitrate and urea were characterized by the highest content of Al, Mn, Sr, Zn, Cd and Mo. Urea caused a significant increase in the content of Cu, Li and V, while ammonium nitrate resulted in an elevated level of Fe and Co accumulation in cabbage heads. Fertilization with (NH4)2SO4 led to a substantial decrease in the content of Al, Mo and V, and fertilization with NH4NO3 caused a decline in Sr concentrations in cabbage in comparison with other objects of the experiment. Each nitrogen fertilizer resulted in the decreased concentrations of Ti in cabbage heads. Applied nitrogen fertilizers significantly influenced the contents of readily soluble forms of B, Fe and Pb in soil after cabbage cultivation.

Tabbacco wastes, coffee production wastes, cocoa shells and their mixtures exerted the positive influence on total and marketable yields of carrot's roots in comparison with manure. Organic materials (investigated factors) did not have clear influence on the nutrient value (dry matter, total sugar, carotenoides) of carrot. Roots of carrot which were fertilized by Polifoska (mineral fertilizer) and coffee production wastes bail contened the least nitrates of all. Visibly had occured differences in quanlity and qantity among years. Tabacco wastes, coffee production wastes, cocoa shells and their mixtures can be use in fertilizing of carrot.
