Effect of Long-term Fertilizer Application on the Concentration and Solubility of Major and Trace Elements in a Cultivated Andisol

Abstract

The concentrations and solubility of major and trace elements in soils collected from a field for long‐term experiments maintained for more than 60 years and the neighboring area were investigated in order to reveal the influence of soil management on their behavior in soils. No obvious differences in the element concentrations in soils were observed except for P and U, whose concentrations were elevated in the surface soils of the experimented field because of the long‐term application of phosphate fertilizers. Soil acidification associated with the successive applications of potentially acid fertilizers had changed the solubility of many elements as follows: the solubility of Li, Be, Al, Mn, Co, Zn, Y, Cd, Ba and rare earth elements increased, while the solubility of P, As, Se, Nb, Sb, Mo and V increased by liming. In the uncultivated soils, the concentrations of Fe, Zr, Nb, Hf and Th in the water extracts were relatively high, and a certain amount of these elements in the water extracts may occur in colloidal forms.

Long-Term Effects of Organic Amendments on Soil Fertility

“…By contrast, low pH in the soil, caused by more than 60 years of rice straw compost applications, may have enhanced the concentration of metals in the water-soluble fraction (Takeda et al, 2005).…”

Selective Dissolution Analysis of Major and Trace Elements in an Allophanic Andisol Acidified by Long‐Term Fertilizer Application

“…Thus, the main objective of the present study was to examine the detailed effect of acidification on the allophanic Andisol using the selective dissolution analysis. When the WS fraction increases, the WS elements may translocate downward in a humid climate although TCE in the Ap horizon soil was only slightly affected by the present degree of acidification (Takeda et al 2005). However, the allophanic Andisol in this area was derived from several tephra deposits of different ages from the Towada caldera (Shoji, Nanzyo, and Dahlgren 1993).…”

“…A long-term experimental field, established in 1940 at the Fujisaka Branch, Aomori Agricultural Experiment Station in Towada, Aomori Prefecture, Japan (latitude: 409 35u N, longetude: 1419 15u E), was used to examine the effect of fertilizer application on the chemical composition of an allophanic Andisol. We previously found that the solubility of lithium (Li), beryllium (Be), Al, manganese (Mn), cobalt (Co), zinc (Zn), yttrium (Y), cadmium (Cd), barium (Ba), and rare-earth elements in soil increased, whereas the solubility of phosphorus (P), arsenic (As), selenium (Se), niobium (Nb), antimony (Sb), molybdenum (Mo), and vanadium (V) decreased with acidification (Takeda et al 2005). However, the total concentration of the studied elements were only slightly affected by the long-term fertilizer application except for P and uranium (U) (Takeda et al 2005).…”

The U concentration in the surface layer increased because of phosphate fertilizer application to this field (Takeda et al 2006).…”

Effects of 42-year long-term fertilizer management on soil phosphorus availability, fractionation, adsorption–desorption isotherm and plant uptake in flooded tropical rice

“…Several long-term fertilizer experiments have been conducted to quantify changes in major and trace elements in soils [2]. Phosphorus (P) deficiency is a universal constraint to crop production and constitutes the second most important soil fertility problem throughout the world [3].…”
