Wood processing by-products such as bark of different wood species and hydrolysis lignin were applied as soil mulch. The lignin-based soil conditioner (LSC) representing a lignin-based polyelectrolyte complex with the different composition (a lignin/polymer mass ratio) was obtained under laboratory conditions and was intended to protect sandy soil from erosion by simultaneous application of a soil conditioner as an adhesive, mulch and plant seeds by hydroseeding. The study revealed the pronounced dependence of the properties of the treated wood-originated mulch on the wood species as well as on the composition, the applied concentration and the application rate of LSC. A comparison of the obtained results showed that the treated hydrolysis lignin was characterised by higher compressive strength, higher water resistance and lower moisture losses from sandy soil for a given LSC composition and application rate than the bark-based mulch. The conditioner concentrations don't have negative impact on the germination of seeds plants of the coastal dune zone.

木材加工副产品，例如不同木材种类的树皮和水解木质素，被用作土壤覆盖物。在实验室条件下获得了具有不同组成（木质素/聚合物质量比）的木质素基聚电解质复合物的木质素基土壤改良剂（LSC），旨在通过同时使用土壤改良剂来保护沙质土壤免受侵蚀。粘合剂，通过水力播种覆盖和种植种子。该研究表明，处理过的源自木材的覆盖物的性质对木材种类以及成分，LSC的施用浓度和施用率具有明显的依赖性。所得结果的比较表明，处理后的水解木质素具有较高的抗压强度，在给定的LSC成分和施用率下，比树皮基覆盖物具有更高的耐水性和较低的沙质土壤水分损失。调理剂浓度对沿海沙丘区种子植物的发芽没有负面影响。
