“…Similar conditions of DOC behavior, which show increases in contents when soil pH decreases, have also been reported in English soils (Cookson et al, 2007). In contrast, Filep et al (2003) found increases in DOC content when applying calcium carbonate in an Arenosol in Kisvarda, Hungary, in an experiment with pots.…”

Soil organic matter (OM) content is a quality indicator, but is an inadequate indicator in the short-term because these changes take place slowly, so dissolved organic components have emerged as an alternative. In volcanic soil subjected to different crop rotations with distinct land use intensity, dissolved organic C and N (DOC and DON) were determined as well as their relationship with total C and N contents in the soil, considering the effects of crop rotation, fertilization level, and soil depth. In humid samples of Humic Haploxerands collected at four depths up to 40 cm, DOC and DON contents were determined by extraction with K2SO4 and filtered. Results indicated interaction between the studied factors, DOC fluctuated between 67.8 and 151.7 mg kg -1 with the highest value with intensive management in rotations that included corn (Zea mays L.) associated with a higher fertilization. DON fluctuated between 4.62 and 37.4 mg kg -1 with the highest value in non-intensive rotations that included prairie. With respect to total C, DOC reached 0.40% with intensive management and the lowest value in non-intensive management. DON showed values between 0.13 and 0.68% with respect to total N with intensive and non-intensive management, respectively. Tillage management affected DOC and DON contents depending on the fertilization level and the depth at which it was determined, and were also affected by the crop included in the rotation, thus making these parameters good indicators to evaluate the effects of agronomic management in the short-term.

“…All extractants indicate that increasing surface lime rate increased quadratically extractable Mn concentration at 0-5 cm layer (Figure 3). Surface liming probably caused an increase on microbial activity and on dissolved organic matter (Filep et al, 2003) at the soil surface. Increased microbial activity can also result in a decrease in the oxidation-reduction potential of the soil, increasing Mn availability (Stevenson, 1986); consequently, manganese (II) forms only relatively weak bounds with organic ligands (Marschner, 1995).…”

Micronutrient availability can be affected by the increase of the soil pH due to surface liming. A field trial was carried out on a loamy, kaolinitic, thermic Typic Hapludox at Ponta Grossa, Paraná State, Brazil. The main objective was to evaluate the effects of surface liming and re-liming on the availability of micronutrients [copper (Cu), iron (Fe), manganese (Mn), and zinc (Zn)] for wheat (Triticum aestivum L.) cropped under a no-till system. A randomized complete block design was used in a split-plot arrangement. The main plots received surface lime applications (2, 4, and 6 Mg ha -1 ) in July 1993. In the subplots, surface lime (3 Mg ha -1 ) was applied again in June 2000. In 2003, before the wheat sowing, soil samples were taken at 0-5, 5-10, and 10-20 cm layers. Soil cationic micronutrients concentrations using different extractants (DTPA-TEA, Mehlich-1, HCl, and Mehlich-3) and solution/soil ratios were determined. Application of lime increased soil pH at 0-5, 5-10, and 10-20 cm. The increase in soil pH by liming did not affect soil organic carbon content. The Mehlich-3 solution had a greater capacity in extracting soil micronutrients. Increasing solution/soil ratio of the DTPA-TEA, Mehlich-1, and HCl solutions generally increased the extraction of Cu, Fe, Mn, and Zn. Liming and re-liming caused a decrease in Mn concentration in the wheat leaves. Leaf concentrations of Cu, Fe and Zn were not affected by liming treatments. The solutions of DTPA-TEA, Mehlich-1, HCl, and Mehlich-3 were ineffective to predict the soil cationic micronutrients availability for a wheat crop after surface application of lime.

“…The production and leaching of DOC is affected by biological factors (McDowell and Likens, 1988;Boissier and Fontvieille, 1995;Christ and David, 1996;Brookes et al, 1999) and by chemical factors, such as pH (or liming) (Andersson and Nilsson, 2001;Filep et al, 2003). However, when compared to anthropogenic disturbances in forest soils (e.g., clear-cutting, land clearing, fire), much less attention has been focused on the effects of natural disturbances on soil properties.…”

To understand changes in soil nutrients in Pinus massoniana forests affected by pine wilt disease (PWD), we examined the seasonal variation in dissolved organic carbon (DOC), dissolved organic nitrogen (DON) and soil nutrients in Hefei, East China. The results showed a considerable decline in the population density and basal area in both highly disturbed (HD) and moderately disturbed (MD) forest stands and an increase in dead pine trees, causing pronounced changes in the stand structure and soil nutrient status. The concentrations of DOC and NO 3 --N were significantly (p < 0.05) higher in every season in the disturbed forests compared to the undisturbed (UD) forest stand. However, during spring and summer, the variation in the DON and NH 4 + -N values was significantly (p < 0.05) lower in the HD forest stand than in the UD stand; total N concentrations were higher in the disturbed forests in every season. During spring and autumn, the variation in total P values was significantly (p < 0.05) lower in the MD forest stand than in the UD stand, whereas the total P values were significantly (p < 0.05) lower in every season in the HD stand than in the UD stand. In this study, disturbance resulted in a considerable increase in DOC, N and NO 3 --N when compared to the UD stand and a pronounced increase in soil nitrate in the HD stand, which may lead to soil acidification, thereby increasing the possibility of soil nutrient leaching.
