In the present paper, new environmental-friendly fertilizer components were produced in biosorption process by the enrichment of the biomass with zinc, essential in plant cultivation. The obtained new preparations can be used as controlled release micronutrient fertilizers because microelements are bound to the functional groups present in the cell wall structures of the biomass. It is assumed ...

BACKGROUND Few studies have considered source-specific micronutrient intake in relation to mortality under the consideration that dietary and supplemental intake could exhibit different effects. OBJECTIVE To evaluate the association between intake of vitamin C, E, folate, beta-carotene from diet and supplements, and overall mortality. Furthermore, to examine effect modification by smoking, al...

Micronutrient malnutrition remains a problem of public health concern in most developing countries, partly due to monotonous, cereal-based diets that lack diversity. The study objective was to assess whether dietary diversity score (DDS) based on a simple count of food groups consumed and DDS using a 10-g minimum intake for each food group (DDS 10g) are good indicators of adequate micronutrient...

OBJECTIVE We investigated the relationship of micronutrient deficiencies with the frailty syndrome in older women living in the community. METHODS Frailty status and serum micronutrients were assessed in a cross-sectional study of 754 women, 70-80 years old, from the Women's Health and Aging Studies I and II. RESULTS Among nonfrail, prefrail, and frail women, respectively, geometric mean se...

BACKGROUND To explore the relation between micronutrient status and health, it is important to understand which markers of micronutrient status can be relied on and under what circumstances. OBJECTIVE The objective of this article was to develop a common systematic review methodology for use in the assessment of micronutrient status for selenium, iodine, copper, zinc, riboflavin, vitamin B-12...

Subclinical micronutrient deficiency in older adults is associated with chronic age-related diseases and adverse functional outcomes. In Germany, the older population is at risk of insufficient micronutrient intake, but representative studies on micronutrient status in old and very old adults are scarce. This study's objectives were to estimate the prevalence of subclinical vitamin D, folate, v...

BACKGROUND Wasting and micronutrient malnutrition have not been well characterized in adults with pulmonary tuberculosis. We hypothesized that micronutrient malnutrition is associated with wasting and higher plasma human immunodeficiency virus (HIV) load in adults with pulmonary tuberculosis. METHODS In a cross-sectional study involving 579 HIV-positive and 222 HIV-negative adults with pulmon...

OBJECTIVE Low micronutrient intakes in adolescents are frequently reported. We assessed micronutrient intakes in adolescents to determine whether supplement use optimises intakes. METHODS Dietary intake was assessed using a food frequency questionnaire in 17 year old participating in the Western Australian Pregnancy Cohort (Raine) Study (n=991). We calculated median daily micronutrient intake...

Increased fertilizer input in agricultural systems during the last few decades has resulted in large yield increases, but also in environmental problems. We used data from published papers and a soil testing and fertilization project in Shaanxi province during the years 2005 to 2009 to analyze chemical fertilizer inputs and yields of wheat (Triticum aestivum L.) and maize (Zea mays L.) on the f...

Farmers in developing countries sometimes receive incorrect and misleading information regarding the fertilizer inputs into food production, especially during crises or times of unusually high demand. In the early 2000’s farmers of Thailand were sold fake fertilizer or advised to apply excessive amounts of fertilizers by fertilizer dealers. The problem was so pervasive that a protocol was devel...
