“…The effect of liming is visible mainly in the humus layer and in the upper mineral layer A, which is consistent with many other studies (Kreutzer 1995;Meiwes et al 2002;Lundström et al 2003;Schaaf, Hüttl 2006). In the deeper mineral soil (down to 30 cm) only the increase of pH and exchangeable magnesium was found significant.…”

ABSTRACT:The article focuses on changes in soil chemistry observed on plots limed in 2000 in the western Ore Mts. (Krušné hory) on the basis of chemical analyses done before liming and repeated in 2002, 2005 and 2010. In the deeper mineral soil (down to 30 cm), only the increase in pH and exchangeable magnesium was significant. The increase in exchangeable calcium in upper soil layers was significant in 2002 and 2005 only; ten years after liming the effect was negligible, although the number of Ca deficient samples was lower than in 2000. The exchangeable Mg content increased above the deficiency limit in all samples of upper soil, and an increase was also found in the deeper mineral soil. These changes were reflected in increasing base saturation and lower base cations/aluminium ratio in the organic and organomineral soil layer. Despite these positive shifts, calcium and magnesium deficiency and very low base saturation (< 10%) still prevail in the deeper mineral soil (2-30 cm) and are common even in the upper mineral soil. The increased total nitrogen level observed two and five years after liming indicated enhanced decomposition of the humus layer. On the other hand, N content in the upper organic (FH) horizon as well as in deeper mineral soil did not change significantly.

Forest fertilization: Trends in knowledge and practice compared to agriculture

Plantation forestry continues to intensify and grow in area, with a concomitant increase in fertilizer demand. Virtually no fertilizer is used on non-plantation forest systems. The scale of fertilizer use per ha per year in a small proportion of plantation systems is now similar to some agricultural production systems, but the total area of plantation forestry remains only a few percent of that used for agriculture. Hence, in a global context, forestry is a minor user of fertilizers. In relation to the knowledge base for fertilizer management, forestry and agriculture have similar practical questions that drive research, i.e. nutritional diagnosis and the development of fertilizer prescriptions that optimize production, environmental and economic goals. Much of this research is soil-climate-species-management specific. During the past few decades, solution culture methods were developed that maintain stable internal nutrient concentrations, which were essential for improving our understanding of nutrient-growth relationships. The development of plant production models that include the mechanistic simulation of nutrient supply and uptake are at an early stage of development. Plantation forestry and agriculture lack a mechanistic basis for evaluating base cation availability that accounts for Al-pH-root interactions. Further developments in this field could assist in rationalizing the use of lime. There is a lack of resources available in plantation forestry, and probably also in agriculture in some countries, to develop and refine calibrations of traditional types of soil and foliar analyses. Further testing of soil solution approaches is warranted. Further research on resource use efficiency, wood quality, rhizosphere relations, and mixed-species systems in relation to fertilization is also warranted.

“…Aber et al (1995Aber et al ( , 1998) explained declining mineralization rates as a longer-term response to N additions, although DIN supply might initially stimulate N mineralization (McNulty et al 1990). Meiwes et al (2002) attributed the reduced microbial humus mineralization rate to increased soil acidity, increased availability of toxic heavy metals and increased N content of the organic matter, or a combination of these factors. All of these mechanisms may have contributed to the large LFH-layer build-up at this site and to the disproportionate increase in its N concentration.…”

Nitrogen biogeochemistry of a mature Scots pine forest subjected to high nitrogen loads

Nitrogen (N) biogeochemistry of a mature Scots pine (Pinus sylvestris L.) stand subjected to an average total atmospheric N deposition of 48 kg ha -1 year -1 was studied during the period 1992-2007. The annual amount of dissolved inorganic nitrogen (DIN) in throughfall (TF) averaged 34 kg ha -1 year -1 over the 16-year monitoring period. The throughfall fluxes contained also considerable amounts of dissolved organic nitrogen (DON) (5-8.5 kg N ha -1 year -1 ), which should be incorporated in the estimate of N flux using throughfall collectors. Throughfall DIN fluxes declined at a rate of -0.9 kg N ha -1 year -1 , mainly due to the decreasing TF fluxes of ammonium (NH 4 ), which accounted for 70% to TF DIN. The decrease in TF DIN was accompanied by a decrease in DIN leaching in the seepage water (-1.6 kg N ha -1 year -1 ), which occurred exclusively as nitrate (NO 3 -). Nitrate losses in the leachate of the forest floor (LFH) equalled the TF NO 3 -delivered to the LFH-layer. On the contrary, about half of the TF NH 4? was retained within the LFH-layer. Approximately 60% of the TF DIN fluxes were leached indicating that N inputs were far in excess of the N requirements of the forest. For DON, losses were only substantial from the LFH-layer, but no DON was leached in the seepage water. Despite the high N losses through nitrate leaching and NO x emission, the forest was still accumulating N, especially in the aggrading LFH-layer. The forest stand, on the contrary, was found to be a poor N sink.
