“…In our study, however, Cd concentration in potato tubers was not correlated with soil DTPA-extractable Cd (R 2 00.003, P 0.05) (Fig. 3) or Mehlich 3-extractable Cd (R 2 00.14, P 0.05) (data not shown), in agreement with results from field experiments conducted in Australia (McLaughlin et al 1997). Mehlich 3-extractable Cd was significantly (P B0.005) correlated with DTPA-extractable Cd in soils (Fig.…”

“…While many studies on Cd accumulation in potato tubers and the effects of P fertilization on Cd uptake by potato have been conducted in Australia (McLaughlin et al 1997;Dunbar et al 2003), the United States of America (Mulla et al 1980;Wolnik et al 1983;Gartrell et al 1986), and Bolivia (Oporto et al 2007), there are no reports on potato Cd concentration in Canada.…”

Cadmium (Cd) is a heavy metal present in soils that can accumulate at relatively high levels in potato (Solanum tuberosum L.) with no negative effect on growth. Our objectives were to investigate Cd concentration in potato tubers produced in Quebec and to relate some soil characteristics, especially pH, P, and Cd, to tuber Cd concentration. Potato tubers (n = 75) and soil samples (n = 64) were collected from 1999 to 2006 at five experimental sites. Tuber Cd concentration ranged from 0.04 to 0.20 mg kg–1 dry matter (DM), with a median value of 0.11 mg kg–1 DM, and never exceeded the proposed tolerance for potato of 0.05 mg kg–1 fresh weight or about 0.25 mg kg–1 DM. Tuber Cd concentration was weakly, although not significantly, related to soil available P content (r2 = 0.53, P = 0.064), indicating a possible influence of soil P on Cd uptake by potato. Tuber Cd concentration was not directly related to soil pH, or to DTPA- or Mehlich 3-extractable Cd in soils. The log-transformed tuber Cd concentration was significantly (r2adj = 0.87, P < 0.01) related to both soil pH and VCd13, a generated variable that accounts for interactions between soil Cd and clay content, soil organic matter, and soil concentrations of Fe, Al, Mn, P, K, S, Ca, Cu, Zn, and B. Single factors such as soil Cd, soil P, or pH could not solely explain Cd accumulation in tubers; interactions between selected soil properties and soil Cd should be considered.Key words: Cadmium, phosphorus, Solanum tuberosum L., accumulation

“…The results also suggest that if PR and PAPR are as agronomically effective as fully acidulated P sources, the former may contribute less to Cd uptake by crops than WSP sources. McLaughlin et al (1997) reported that increased chloride (Cl) content in irrigated waters imposes a high risk of producing crops with high Cd concentrations. It is believed that Cl ions form relatively strong complexes with Cd 2?…”

This review discusses and summarizes the latest reports regarding the agronomic utilization and potential environmental effects of different types of phosphate (P) fertilizers that vary in solubility. The agronomic effectiveness of P fertilizer can be influenced by the following factors: (1) water and citrate solubility; (2) chemical composition of solid watersoluble P (WSP) fertilizers; (3) fluid and solid forms of WSP fertilizers; and (4) chemical reactions of P fertilizers in soils. Non-conventional P fertilizers are compared with WSP fertilizers in terms of P use efficiency in crop production. Non-conventional P fertilizers include directly applied phosphate rock (PR), partially acidulated PR (PAPR), and compacted mixtures of PR and WSP. The potential impacts of the use of P fertilizers from both conventional (fully acidulated) and non-conventional sources are discussed in terms of (1) contamination of soils and plants with toxic heavy metals, such as cadmium (Cd), and (2) the contribution of P runoff to eutrophication. Best practices of integrated nutrient management should be implemented when applying P fertilizers to different cropping systems. The ideal management system will use appropriate sources, application rates, timing, and placement in consideration of soil properties. The goal of P fertilizer use should be to optimize crop production without causing environmental problems.

Nutritional requirements of potatoes

Plant nutrition is the practice of providing to the plant the right nutrient, in the right amount, in the right place, at the right time. This paper gives an overview of the roles that each of the 16 essential nutrients have in plant nutrition, their relative mobility as related to deficiency symptom expression, and what is generally known about nutrient responses to field applications on potatoes (Solanum tuberosum L.) in the USA and Canada. Maintaining high crop yields with minimum nutrient losses to the environment is and will continue to be a significant challenge to the potato producer. Additional nutritional research efforts in geneticallymodified plants, precision agriculture, food quality and safety, fertilizer impurities, and other management concerns should significantly help the producer in this effort.
