“…The SER is an important factor that influences stand density [43,44]. The results of this study show that there is a significant correlation between soil evaporation and stand density (R = 0.710 **) ( Figure 2, Table 4) and the SER is one of the main variables affected by the SMC [45]. This study suggests that the SER is 0.1 g•D −1 in R. pseudoacacia forestland on the western Loess Plateau (Figure 2, Table 3) and represents an important factor influencing vegetation degeneration and soil desiccation; this finding is consistent with the findings of Shangguan [46].…”

Improving low-efficiency artificial forests represents a popular forest hydrological issue, and exploring the optimal stand density (OSD) of low-efficiency artificial forests is an effective method for improving the soil conditions of forestland to prevent the deterioration of ecological function. Water and nutrients were the main limiting factors for vegetation growth. However, relatively few studies addressed the optimization of stand density based on these two factors at the same time. In this study, a total of 176 standard plots (20 × 20 m2) with six stand densities (~500, ~1000, ~1500, ~2000, ~2500 and ~3000 plants·hm−2) were established to investigate the water resources (soil moisture content (SMC), soil evaporation rate (SER), and vegetation transpiration rate (VTR)) and soil nutrient resources (total nitrogen (TN), total phosphorus (TP), total potassium (TK), calcium (CaCO3), organic matter content (OMC)) in low-efficiency Robinia pseudoacacia forestland on the Loess Plateau in western Shanxi, China from June to September each year from 2017 to 2018. The relationships between stand density and water and nutrient resources were analysed with the response surface method (RSM). The RSM results indicated that the OSD averaged 1594 plants·hm−2 and ranged from 940 to 2386 plants·hm−2. The percentage of standard plots with an unreasonable stand density was 35.29%, and 65% of these plots had a value that was higher than the maximum in the range while 35% had a value that was lower than the minimum. These results indicate that the current stand density should be manipulated to fall within the identified OSD range to ensure the normal functions of soil and water conservation in R. pseudoacacia forests. The results of this study serve as a guide for optimizing the stand density of low-efficiency R. pseudoacacia forests in China.

“…Due to the increase of water content in soil, the specific heat capacity of soil increased. When soil is heated, evaporation occurs and water content decreases slowly [29,30]. Hydrophilic groups in vinyl acetate polymer form a close bond with soil particles through hydrogen bonds and cation exchange.…”

Soil stabilizer can enhance the soil properties, which can improve ecological environmental problems such as soil erosion and slope instability. This study investigates the water-related and mechanical properties of soil stabilization using a polymer soil stabilizer solution synthesized from vinyl acetate polymer. The water properties test, mechanical properties test, durability test and seed growth test were carried out in the laboratory. Also, the effect of vinyl acetate polymer was verified by field tests. The results revealed that vinyl acetate polymer can enhance the water-retaining property, anti-erosion resistance, strength property and durability of soil, all of which increase with the increase of polymer concentration. At the same time, the polymer also has a certain promoting effect on vegetation growth. In addition, field tests proved that vinyl acetate polymer has good effects on soil engineering. These results could be applied as a reference for vinyl acetate polymer-improved soil engineering.

“…The cause for the increased evaporation could be linked to the particle size of the depleted marc, less than 100 microns. An et al [43] found that soil surface characteristics and atmospheric conditions influenced the evaporation rate and overall moisture content of soils. The soil grain sizes in the study influenced the evaporation process [43].…”

Grape (Vitis vinifera L.) marc has long been utilized as a compost feedstock. However, this process takes an extended period of time due to the phytotoxic chemical composition of the marc. Removal of these compounds presents an opportunity to utilize the grape marc as a growing medium. Following a water-based extraction procedure to remove polyphenolic compounds of interest, analysis of the depleted marc showed a decrease in the content of these compounds, and in nutrient and trace element levels. Carrot (Daucus carota L.) and corn (Zea mays L.) seedling emergence in the depleted marc and blends with compost were not adversely affected, demonstrating its effectiveness for growing plants at all ratios. A 50:50 blend of compost and depleted grape marc resulted in plant growth equivalent to the compost alone. This combined with the observed water holding capacity suggests that depleted grape marc, when blended with compost, can be a suitable alternative to peat or coconut coir for seedlings.
