“…A review on variations of antioxidants also in relation to the kind of cultivation [36] does not report any article on the specific issue of polyphenols variation. Total average phenolic content was slightly higher in organic agriculture in a 3-year study (1 and 7% for the two investigated cultivars) [70]. In a 2-year study, on two cultivars, no differences were pointed out [71] and on four cultivars for 3 years no differences were found apart from the behavior of one cultivar along 2 years (one case higher under organic cultivation and in the second higher under conventional cultivation) [72].…”

relevance of scientific studies on this subject. Taking into account the reviews published since 2008, a general overlook on the research topics can emphasize the main current fields in which the research is presently developed. The different subjects which may be inferred are: problems in the analytical assays of polyphenols [1][2][3][4][5], polyphenols composition of fruits and vegetables [6][7][8][9][10], the fate of polyphenols in postharvest technology [11, 12], chemistry and biochemistry [13][14][15][16], polyphenols and food [17][18][19][20][21], polyphenols and health [22][23][24][25][26][27][28]. From this short survey which takes into account only partly the last years, the great number and variety of researches on these plants metabolites can be pointed out. There is a lack of reviews on the relations between polyphenols content, fertilization and agriculture practice, with the exception of a recent review on the possibility of differentiating organic practice by means of secondary plant metabolites in carrots [29], and the review of Stefanelli et al. [18] focused on horticulture quality under minimal nitrogen and water supply.The aim of this review is concerned with the relationships between polyphenols content, fertilization and agricultural practice correlated to soil management. Effect of nitrogen and/or potassium fertilizationAs summed up by Nguyen and Niemeyer [30], the carbon/nitrogen balance (CNB) pathways can be taken into account when studying the effect of nitrogen fertilization on phenolic content. Phenylalanine is the rate-limiting precursor for phenylpropanoid synthesis (e.g., lignin, flavonoids and condensed tannins), and at the same time, it is an essential amino acid for protein synthesis. Plant growth is heavily dependent on protein synthesis for the manufacture of photosynthetic, biosynthetic and regulatory enzymes, as well as for structural protein, and phenolic synthesis Abstract The review deals with polyphenol content of vegetables and fruits under different experimental conditions. The effect of fertilizers, mainly nitrogen containing fertilizers, on qualitative and especially quantitative content of the polyphenols mixture, was reviewed. Soil nitrogen affects both anthocyanins and flavonoids content, and generally, a higher polyphenolic content is observed when less nitrogen fertilizer is added to the soil. Also the effect of different agricultural management (conventional, organic, biodynamic, integrate) is reviewed with respect to polyphenols. In this case, a major effect has pointed out in the case of vegetables, while agricultural practice affects in a minimal way fruits polyphenols content. The effect of different management is, however, hardly pointed out, since many environmental factors are involved and affect polyphenols biosynthetic pathway.

“…REMBIAŁKOWSKA (2007) realizando estudo na qualidade de produtos orgânicos verificou que esse tipo de produção induz menores teores de nitrato e resíduos de pesticida e maior teor de vitamina C, aminoácidos essenciais e açúcar total. Outros autores também relataram aumento de vitamina C em espécies hortícolas orgânicas, como em couve chinesa, alface e repolho (ISMAIL & FUN, 2003) e tomates (CHASSY et al, 2006), em comparação as convencionais. Segundo CARVALHO & MULLER (1996), a planta de jambu é rica em elementos nutritivos como ferro, e ainda possui as vitaminas B1, B2, niacina, vitamina C, vitamina A e cálcio.…”

“…Benbrook and Greene (2008) point to the higher levels of good fats and antioxidants in organic food products. Others (Chassy et al, 2006;Asami et al, 2003;Heaton 2001;Weibel et al, 2000) have also found a higher antioxidant content in organic crops. In a long-term study, Mitchel et al (2007) found that health-promoting flavonoids in organic products are twice more than in conventional tomatoes.…”

While much has been published on the advantages of organic agriculture, less has addressed its potentials and challenges to fight undernourishment in developing countries. This article aims at reviewing the main potentials and challenges of this approach when dealing with "undernourishment" as a multi-faceted concept in developing countries. Accordingly, two main issues of the concept which are "food security" and "food safety" are discussed in the context of both developed and developing countries to understand their different food policies' priorities. Next, the main potentials, challenges and tradeoffs of the organic approach are scrutinized to understand whether the approach is capable to provide a secure or safe food production system and therefore to understand whether it can meet the food policies' priorities in developing countries. With respect to food security, the article concludes that conventional and biotechnological approaches still appear to produce higher yields though considering many advantages of organic agriculture, it could, in long run, be more conducive than now to meet food security. Hence, we still need both conventional and 1 Corresponding author. Email: hossein.azadi@ugent.be, Tel. +32 (0)9 264 46 95.

Accordingly, the article emphasizes on providing farmers in developing countries with the possibility of implementing different approaches. Therefore, policy makers should be aware of a realistic and gradual transition from the other approaches to the organic that should be projected only in "long run", and after conducting a series of risk assessment studies on the bases of both 'crop-case" and "region-case".
