“…The continuous cycle of reduced and oxidized soil conditions and organic amendments have a bearing on the transformation of micronutrients in soil (Han and Banin, 2000;Hoang et. al., 2009;Rupa et al, 2001;Saha and Mandal, 2000).…”

Long term effects of lantana (Lantana camera L.) residue and fertilizer application were studied on copper (Cu) fractions in a Typic Hapludalf under rice-wheat cropping at Palampur, India (32º6'N , 76º3'E). A partitioning of soil Cu revealed residual Cu and organically bound Cu as the most dominant fractions followed by Cu occluded by free oxides, specifically exchangeable Cu and soil solution and exchangeable Cu. Continuous incorporation of lantana after 12 years resulted in redistribution of Cu from non-available forms to readily and potentially available forms in soil. All the Cu fractions were positively interrelated amongst themselves and with grain yield and Cu uptake in rice and wheat crops. Specifically exchangeable Cu followed by organically bound Cu were the most important Cu fraction contributing towards grain yield and Cu uptake in rice and wheat crops.

“…(1996) found that reducing conditions favoured Cu solubilization, but noted that the effect was smaller than that of pH. In contrast, Gambrell & Patrick (1989) imposed controlled conditions of Eh and pH and report that water‐extractable Cu decreased with decreasing Eh, in agreement with the observation of Saha & Mandal (2000) that prolonged flooding (75 days) decreased extractable Cu.…”

“…Although the change of these variables as a function of incubation time and conditions is not the main objective of this work, it should be noted that they are largely in good agreement with other reported trends. For example, flooding rapidly induced strongly reducing conditions, with a consequent increase in pH (Atta et al ., 1996; Saha & Mandal, 2000) and water‐soluble Mn (Charlatchka & Cambier, 2000; Mansfeldt, 2004). Apart from three outlying points, water‐soluble manganese was a sensitive probe of the redox potential, as illustrated by the need for a different scale for the flooded and aerated soils.…”

Variations in soil conditions can influence the speciation and hence availability of copper. We have followed the evolution of water-extractability of both native and added copper in a clay-loam topsoil over 5 months. The effects of addition of organic amendments, either leaf compost or lucerne straw, were studied. Soils were incubated under controlled conditions either moist and well-aerated, or flooded. Other chemical properties were monitored (pH, redox potential, water-extractable organic carbon, iron and manganese). Freshly added Cu was initially more soluble than native Cu, but the contrast decreased with time. Solubility was greater in flooded soils than in aerated samples. Solubility also increased with increasing pH, contrary to often-reported trends. Although the extractability of added Cu increased with increasing dissolved organic carbon, as expected from the formation of complexes in solution, that of native soil Cu did not. Large, short-lived flushes of Cu were associated with flushes of dissolved organic matter, particularly from decomposition of lucerne straw, but these relations were not always statistically significant when the entire data set was considered. The total amount of dissolved organic carbon is not a sufficiently sensitive probe to assess the extent to which Cu is solubilized by the formation of complexes in soil solution. The changing composition of soil and soil solution during incubation led to 10-fold differences in the proportion of Cu that was water-extractable. Single measurements of extractability can therefore never give an accurate estimation of mobility and availability of copper in soil.Evolution du cuivre de sol extractible a`l'eau en fonction des apports en matie`re organique et de l'ae´ration Re´sumeD es variations des proprie´te´s des sols peuvent influer sur la spe´ciation et donc la disponibilite´du cuivre dans le sol.

“…The greater availability of Cu observed in the soil solution in the present study can be an interplay of the above factors and confirms the observations made by the above workers. The increased availability of copper in the soil solution at lower concentration of added copper can also be supported by the views that at the beginning of incubation under submergence, more than 85% of the applied Cu was transformed into water-soluble plus exchangeable form (Saha and Mandal 2000). Cu adsorption by kaolinite increased with increasing initial concentration of copper as well as increasing levels of added copper (Choudhary and Khanif 2000).…”

Nutrient sorption studies were carried out as a part of a mega project on "Yield maximization in cassava (Manihot esculenta Crantz) through systematic approach in fertilizer use" to find out the sorption characteristics of major, secondary, and micronutrients [i.e., phosphorus (P), potassium (K), sulfur (S), copper (Cu), zinc (Zn), manganese (Mn), and boron (B)] in a typic kandiustult of Kerala, India. The sorption curve fitted by using this study along with the results of preliminary soil analysis and critical level of these nutrients were used to optimize the nutritional status of this soil. Sorption study revealed that P, K, S, and B were limiting and others were sufficient for this soil. The quantities of the limiting nutrients required to optimize the soil nutritional status were estimated from the sorption curve as P, K, S, and B at 136 mg mL 21 , 0.338 meq 100 mL 21 , 20 mg mL 21 , and 6.025 mg mL 21 , respectively.
