The chemical composition of chop samples at the end of every tumbling experiment was determined. The total moisture content was determined by the drying method as recommended by the Association of Official Analytical Chemists (AOAC, 2000 ). Fat content was determined by using an ether solvent extraction system. Crude protein content was determined by the Kjeldahl method with an automatic nitrogen analyzer (Kjeltec 2300 Analyzer Unit, Foss Tecator A B, Höganas, Sweden).

The protein content was calculated from the total nitrogen determined by Kjeldhal method, based on Roda and Lambri [25 (link)] and using 6.25 as the conversion factor according to AOAC method 970.22 [26 ]. Nitrogen content was determined using the digestion block and steam distillation (Tecator 2020 Digestor, Foss, Hillerød, Denmark) with colorimetric endpoint detection (Kjeltec 2300 Analyzer Unit, Foss, Denmark). Samples were evaluated in duplicate and expressed as a mass percentage.

The dichromate oxidation method was used to measure the SOC and the Kjeldahl method (Kjeltec 2300 Analyzer Unit; Foss, Hogana, Sweden) was used to analyze the TN (Bremner, 1996 ; Nelson & Sommers, 1982 ). Soil pH was measured using a pH meter after shaking for 30 min with a soil: water suspension of 1: 2.5 w/v. Each measurement was performed in triplicate.

The leaves of the poplar plantlets were washed with demineralized water to remove surface impurities, and dried at 65 °C for 48 h. The total concentration of individual mineral components in the leaves was measured (K, Na, Mg, Ca, P, N, Cl). Chemical analyses were performed in a certified laboratory. The total concentrations of K, Na, Mg, and Ca were determined by atomic absorption spectrophotometry (Varian AA280FS). In order to verify the analyses, certified material was used (M3) (Steinnes et al., 1997) . The concentration of phosphorus was determined colorimetrically (HACH LANGE DR 3800 colorimeter). In order to verify the analyses, certified material was used (ISE sample 912). Nitrogen analysis was performed using the Kjeldahl method, with the Kjeltec 2300 Analyzer Unit (FOSS TECATOR), according to the AN 300 application. Verification of the analyses was made using certified material (ISE sample 912). Chloride analysis was performed using ion chromatography (DIONEX ICS 1100, with an AS9-HC column). In order to verify the analyses, certified material was used (IPE sample 993).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
