The composition of modified milk for babies is based on the model of breast milk. Milk replacement formulas are produced on the basis of cow’s milk so it is necessary to modify all the nutrients in order to make them resemble most closely the model. Determination of babies’ nutritional requirements is based on the knowledge of women’s breast milk, which is regarded the best possible food in the first period of infant life. The concentration of mineral elements in breast milk is low and the total content of ash amounts to 0.2 g⋅dl-1. The content of sodium, potassium and chlorine is three times as low as in cow’s milk. The source of individual elements for babies is their food, though some elements are provided in drinking water and supplements. Typically, mineral elements are absorbed more effectively in the periods of intensive growth. It should be remembered that the mineral elements found in breast milk are characterised by much higher bioavailability than those present in modified milk. The major requirement for modified milk to be registered and authorised for sale in Poland is the conformity of its mineral composition with international recommendations. The objective of the present work was to establish the content of mineral components in powdered milk used in the nutrition of infants in the first months of their lives. All the examined preparations were labelled as “a special nutrition product”. They were purchased in different groceries in Lublin in October 2007, all before their use-by date. The shares of Mg, Zn, Cu, Ca, Mn, Na, Fe and K were marked in the samples. It was demonstrated that all the examined milk samples contained much more Ca and Cu in comparison to recommended norms, whereas they were deficient in Mg and Mn.

On the basis of a 4-year study, the effect of maize fertilization method on the content of mineral components and the utilization of phosphorus from fertilizer were evaluated. Two methods of fertilization were used: by broadcasting and by fertilization in rows. The effect on the content of mineral components was studied by increasing the fertilization doses from 17.4 kg P ha⁻¹ to 56.7 kg P ha⁻¹ and by the application of superphosphate and ammonium phosphate. It was found that fertilization in rows combined with seed sowing increases the content of phosphorus and nitrogen and raises the percentage of phosphorus utilization from fertilizer in comparison with the fertilization by broadcasting in the initial stage of development. Ammonium phosphate exerted a better influence on the uptake of phosphorus and nitrogen by plants and on the percentage of phosphorus uptake in comparison with superphosphate.

Food is the main source of mineral elements but some are also provided with drinking water and supplements. Juices, for example, are an important source of mineral elements. In infants’ diet minerals are provided mainly by fruit and vegetable purée juices. Infants and young children should be given juices labelled as “special purpose food”. Pasteurised juices are recommended for infants, as they are free of bacteria and toxins, a condition that cannot be completely fulfilled while making juices at home. The aim of the present work was to determine the content of some minerals in fruit and vegetable juices for infants and children under three years of age. The research material consisted of juices, all before their use-by date, purchased in grocer shops in Lublin in January 2006. In total 20 juices were examined, 8 of which were labelled as ‘special purpose food’, 2 were recommended by the National Food and Nutrition Institute and ten juices were labelled as ‘food for young children’. Juices make an important source of minerals in the diet of infants and young children. The most valuable ones are the fruit and vegetable purée juices, as they provide significant amounts of dry mass which includes fibre, minerals and vitamins. Differences in the content of particular mineral elements in juices result primarily from their composition. Although juices for infants and young children should not contain any additives, products without certificates must be treated with caution as it cannot be excluded that some may contain prohibited compounds, e.g. calcium ascorbate or calcium chloride.

Studies were carried out in the Department of Pomology on the area of the Agricultural and Pomological Experimental Farm in Przybroda belonging to the Agricultural University in Poznań. In the years 2005–2006, apple-tree rootstocks M9 were planted into rhizoboxes with soil taken from different orchard localities. It was found that the previous method of soil use had an essential effect on the growth and the chemical composition of the planted rootstocks. Cultivation of rootstocks in rhizoboxes showed that the growing for many years of the same species deteriorates the growth. On the other hand, a change in the grown species decreases the risk of soil fatigue.

Owing to its high protein and low fat content, turkey meat is regarded as dietetic. It also has a beneficial composition in terms of amino acid and mineral content. The study involved an analysis of selected elements: zinc, magnesium, calcium, sodium, potassium and phosphorus in breast muscles of male turkeys BIG 6 fed on fodder with various content of oatmeal (0%; 5% and 10%). The content of selected elements was determined in previously mineralised samples: zinc, magnesium and calcium – by AAS, using a UNICAM 939AAA Solar flame atomic absorption spectrometer; sodium and potassium – by flame photometry with a Carl Zeiss Jena FLAPHO 4 flame photometer, and phosphorus – by colorimetric measurement with the hydroquinone reagent at a wavelength of 610 nm. The results were processed with a single- factor analysis of variance with the Statistica 8pl computer program, and the significance of differences was determined with Duncan’s test. Oatmeal application in the analysed doses in turkey feeding has been shown to reduce the content of the elements under study in turkey meat. The differences for the analysed elements have not been shown to be statistically significant (P = 0.05), except for sodium, whose content – unlike that of other elements – grew with the oatmeal content in the fodder

Sweet pepper belongs to vegetables with high biological value, characteristic taste and health-promoting features, which depend on the content of many elements with antioxidant capacity. Pepper fruits are an important source of mineral components for people. The aim of this study was to determine the effect of different foliar feeding regimes with the use of calcium on the content of macro- and microelements in sweet pepper fruits. The experiment with the sweet pepper cultivar Caryca F1 was carried out under field conditions in 2010-2011. Various calcium preparations: Ca(NO3)2 , Insol Ca, Librel Ca, were applied in plant nutrition. The evaluated preparations were sprayed 3 and 5 times, in the concentration of 1%, until complete wetness of the plants. Control fields were sprayed with water. No significant influence of the examined factors on the dry matter content (%) was recorded in the fruits of cv. Caryca F1 sweet pepper cultivated in a field. However, the influence of the applied calcium preparations on the content of N-total, P, Ca, Fe, Zn, Cu in pepper fruits was shown to vary. After an application of Ca(NO3)2, higher concentrations of K, Zn, Cu were demonstrated; an application of Insol Ca stimulated a higher content of K and Cu; more K, Fe, Zn and Cu occurred in the fruit after feeding with Librel Ca, and the content of P was lower after an application of Insol Ca and Librel Ca, all versus the control. The different number of treatments did not have any significant effect on the chemical content of pepper fruits, except for Fe and Mn, where 5 treatments increased the content of these elements in pepper fruits. The positive influence of the applied calcium preparations and of the number of treatments on the accumulation of Ca in pepper fruits were proven. For example, 5 treatments were demonstrated to have increased the calcium content in fruits by an average 25.3%, and 3 treatments raised the above trait by 15.3% above the control.
