A field experiment, which included 3 treatments and 4 replicate blocks, was established on an acidic, organic matter-rich mineral soil. The treatments were two different doses of ash (10 and 20 t ha\u22121) and an unfertilized control. Application of the ash (by spreading on the ground) produced mean increases of 16% in diameter and 11% in height growth of trees during the first 3 years, considering both doses together; the response was also significant for the subsequent period, particularly with the higher dose of ash (increases of 11% in diameter and 15% in height growth). The ash had a marked effect, although clearly short lived, on pH (H2O) levels (an increase of 0.6 units) and on exchangeable soil K, Ca and Mg. The nutritional status of the plantation was improved, mainly in terms of K, Ca and Mg, and the results of a vector analysis indicated that these elements, particularly K, were limiting forest production.

A four\u00a0year experiment was performed in a Neotropical savanna from the Brazilian plateau (cerrado), in which litter levels were modified, and the resulting changes in biophysical and chemical soil properties were studied. Changes in organic matter decomposition, soil respiration and stem growth of the six most common tree species were also monitored. Compared to litter removal plots, double litter plots had lower maximum soil temperature and higher soil water content, and litter decomposition rates in one of three species studied, consistent with higher soil respiration rates observed in this treatment. With the exception of Ca, there were no significant differences in nutrients between the removal, natural and double litter plots, even though most nutrients tended to increase in the double litter plots by the end of the experimental period, while in the control plots nutrient levels remained relatively constant. Of the six tree species used for growth analysis, only one, Sclerolobium paniculatum, a fast growing species with shallow roots, had a significant increase in stem growth due to litter addition. Preliminary results over four\u00a0years indicate that litter removal and addition resulted in some significant changes and tendencies that indicate that litter is effectively altering ecosystem processes. The information obtained also suggest that nutrient cycling in plots with natural litter levels (control plots) was in a closed loop; most nutrients released by litter decomposition and mineralization were absorbed and reutilized immediately by the plants, thus minimizing nutrient leakage outside the system.", "keywords": ["0106 biological sciences", "TREE GROWTH", "https://purl.org/becyt/ford/1.6", "NUTRIENT CYCLING", "SOIL FERTILITY", "0401 agriculture", " forestry", " and fisheries", "04 agricultural and veterinary sciences", "15.

Application of the ash produced an increase in soil pH, and in the availability of P, Ca, Mg and K. The effects on soil pH and available Ca and Mg persisted for five growing seasons. The prolonged response in this study may be attributable to the effect of ash incorporation, which may have enhanced the solubility of wood ash compounds, despite the partly combusted material present in the ash. The ash improved the nutritional status, mainly in terms of Ca and Mg, and the vector analysis indicated that these elements were limiting forest production. The soluble NPK fertilizer did not produce any improvement in growth relative to the control. The concentrations of heavy metals in both soil and plant tissue were always low and did not increase significantly after application of the wood-bark ash.

The field experiments consisted of two Scots pine and four Norway spruce experiments. The treatments, on three replicate 8\u00a0m\u00a0\u2217\u00a08\u00a0m plots in all field experiments, were whole-tree harvesting, i.e. harvesting all the above-ground biomass with no logging residue left on the site (R0), stem-only harvesting, leaving logging residues on the site (R1), and stem-only harvesting with double the amount of logging residues left on the site (R2). In the R1 treatment the amount of logging residue in the spruce stands was 39\u201354\u00a0Mg\u00a0ha\u22121 dry mass and in the pine stands, 11\u201318\u00a0Mg\u00a0ha\u22121 dry mass.

In pine experiments, logging residues had no effect on tree or stand characteristics. In one pine experiment the amounts of exchangeable base cations increased, and there were also changes in the quality of organic matter: the C/N ratio decreased, and NH4\u2013N, microbial biomass N and C mineralization increased due to residues.

Logging residues did not affect NO3\u2013N concentrations or rates of net nitrification, which in most soils were both negligible. Seedling height and height growth correlated strongly and positively with net N mineralization and its ratio to microbial biomass N. All in all, logging residues improved tree and stand characteristics generally in spruce stands, but the effects on soil properties and processes, if any, occurred mostly in one pine stand.

The dataset includes high-resolution bioclimatic variables obtained from the CHELSA database (M_CHELSA_bio_01 to M_CHELSA_bio_19), which provide essential climate indicators such as annual mean temperature, temperature seasonality, and precipitation throughout various time periods. The climate variables are scaled (temperatures multiplied by 10). Furthermore, variables like Sample_CSV and Series serve as identifiers/ records. The database is ready for ecological modeling, and incorporates biophysical, topographic, soil, and climatic data \u00a0relevant to tree growth study.", "keywords": ["Generalized additive models (GAMs)", "Caucasus region", "Dendrochronology", "Castanea sativa", "Climate change", "Tree growth dynamics"], "contacts": [{"organization": "Metreveli, Vasil, Kreft, Holger, Javakhishvili, Zurab, Mdivani, Sandro, Chikorashvili, Giorgi, Akobia, Ilia, Gavashelishvili, Alexander,", "roles": ["creator"]}]}, "links": [{"href": "https://doi.org/10.5281/zenodo.15374527"}, {"rel": "self", "type": "application/geo+json", "title": "10.5281/zenodo.15374527", "name": "item", "description": "10.5281/zenodo.15374527", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.5281/zenodo.15374527"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2025-05-09T00:00:00Z"}}], "links": [{"rel": "self", "type": "application/geo+json", "title": "This document as GeoJSON", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=tree+growth&f=json", "hreflang": "en-US"}, {"rel": "alternate", "type": "text/html", "title": "This document as HTML", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=tree+growth&f=html", "hreflang": "en-US"}, {"rel": "collection", "type": "application/json", "title": "Collection URL", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main", "hreflang": "en-US"}, {"type": "application/geo+json", "rel": "first", "title": "items (first)", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=tree+growth&", "hreflang": "en-US"}, {"rel": "last", "type": "application/geo+json", "title": "items (last)", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=tree+growth&offset=9", "hreflang": "en-US"}], "numberMatched": 9, "numberReturned": 9, "distributedFeatures": [], "timeStamp": "2026-05-25T23:18:10.753493Z"}
