Abstract

Alders, as an N-fixing species, are widely used as a phytomelioration species at post-industrial sites. The paper presents the effects of litter decomposition of different alder species—black alder, gray alder, and green alder—on changes to the soil solution chemistry of Technosols developed from two types of substrates: lignite combustion waste and sandy substrates from a former sand quarry. Under controlled conditions, the 13-week experiment investigated pH, electrical conductivity (EC), and the chemical parameters—dissolved organic carbon (DOC), dissolved nitrogen (DON), and macroelements S, Ca, Mg, K, and Na content—of filtrates in composites consisting of substrate and litter from alder species was investigated. Alder litter accelerated nutrient leaching processes from soil substrates and had the greatest impact on sandy substrates because fast leaching was possible at low absorption capacity characteristics. Higher leaching rates in sandy substrates were also observed, especially in the cases of DOC, DON, K, and P, in comparison to combustion waste substrates. In the first phase of the experiment in sandy soil substrates, the dominant process is the leaching of DOC from dead organic matter, while in the case of combustion waste, calcium leaching prevails in the first phase. Among the investigated species, black alder had the greatest impact on the chemistry of substrates and solutions, and the dynamic of these processes has a different path at various substrates.

al木垃圾对褐煤燃烧废物和天然沙质基质开发的Technosols化学的影响:实验室实验

抽象的

ders木作为固氮菌种,在工业化后的地点广泛用作植物除菌菌种。本文介绍了不同种类的der木(黑der木,灰色al木和绿色al木)的凋落物分解对由两种类型的底物开发的Technosols土壤溶液化学变化的影响:褐煤燃烧废物和以前采砂场的沙质底物。在受控条件下,这项为期13周的实验研究了pH值,电导率(EC)和化学参数-溶解有机碳(DOC),溶解氮(DON)和宏观元素S,Ca,Mg,K和Na的含量-研究了由al木物种构成的底物和垫料组成的复合材料中的滤液的组成。der木凋落物加速了土壤基质中养分的淋溶过程,对沙质基质的影响最大,因为在低吸收能力特征下可以进行快速淋洗。与燃烧废物基质相比,在沙质基质中也观察到较高的浸出率,特别是在DOC,DON,K和P的情况下。在沙质土壤基质的实验的第一阶段,主要过程是从死有机物中浸出DOC,而在燃烧废物的情况下,钙浸出在第一阶段占主导地位。在所研究的物种中,黑al木对底物和溶液的化学影响最大,并且这些过程的动力学在各种底物上具有不同的路径。与燃烧废物基质相比,在沙质基质中也观察到较高的浸出率,特别是在DOC,DON,K和P的情况下。在沙质土壤基质的实验的第一阶段,主要过程是从死有机物中浸出DOC,而在燃烧废物的情况下,钙浸出在第一阶段占主导地位。在所研究的物种中,黑al木对底物和溶液的化学影响最大,并且这些过程的动力学在各种底物上具有不同的路径。与燃烧废物基质相比,在沙质基质中也观察到较高的浸出率,特别是在DOC,DON,K和P的情况下。在沙质土壤基质的实验的第一阶段,主要过程是从死有机物中浸出DOC,而在燃烧废物的情况下,钙浸出在第一阶段占主导地位。在所研究的物种中,黑al木对底物和溶液的化学影响最大,并且这些过程的动力学在各种底物上具有不同的路径。而在燃烧废料的情况下,第一阶段主要是钙浸出。在所研究的物种中,黑al木对底物和溶液的化学影响最大,并且这些过程的动力学在各种底物上具有不同的路径。而在燃烧废料的情况下,第一阶段主要是钙浸出。在所研究的物种中,黑al木对底物和溶液的化学影响最大,并且这些过程的动力学在各种底物上具有不同的路径。
