“…The results of the preliminary study (data not shown) indicated that the mounding application could increase the distribution of the total roots up to 14 times. It was in line with a previous study that stated application of mounding on saplings of Norway spruce (Picea abies) and Scots Pine (Pinus sylvestris) produced a deeper root system (Celma et al, 2019).…”

Spodosols have been widely used for oil palm plantations, specifically in Kalimantan, Indonesia. However, they are sub-optimal for agriculture due to a lack of water and nutrient-holding capacity and a spodic layer that limits plant root development. Therefore, proper agriculture practices are needed for oil palm to enhance its potential yield. This study aims to determine the effect of the mounding technique on the physiological performance and yield of oil palms in spodosol. The study location was well-managed, with eight blocks of oil palm plantations planted in 2008 on spodosols (Typic Haplohumod) in Central Kalimantan. The mounding technique was applied to four blocks of oil palm planted in 2015, while the remaining four were left without mounding. The parameters observed were soil moisture, transpiration, number of bunches, bunch weight, and yield. The results showed that the average moisture in the mounded soil was 4% greater than the control. Additionally, the average daily transpiration of oil palm with the mounding was up to 2.30 mm day-1 or three times higher than the control. The implication was that the average yield of oil palm increased from approximately 1.84 to 3.71 tons ha-1 year-1 compared to no-mounding treatments. Furthermore, the average yield was 19-66% higher than the block without the mounding application.

“…The newly made pit (Figure 1C) that formed to create the mounding in the interrow can accommodate excess water in the rainy season and maintain soil moisture during the dry season. It was following the previous study by Celma et al (2019). As a result, the pits increased the soil water content (Bohluli et al, 2012).…”

“…Our fundamental questions were: (1) do different site preparation methods and microtopography alter species cover and richness; (2) do site preparation methods and microtopography interact to affect the abundance of forest and grassland habitat species; (3) do patterns of vegetation development differ depending on the soil type. We hypothesise that vegetation composition within the same soil type will be affected by the type of site preparation method because the trench created during disc trenching and the pit created during spot mounding are of different depths, thus having different effects on soil moisture and microtopograpic microclimate (Celma et al, 2019). We also hypothesise that microclimate in pit and trench will have a positive impact on some typical old forest species that could not be found on unprepared soil.…”

“…In Latvia, the most widespread site preparation method is disc trenching, in which the humus layer is removed and pushed to one side, creating a berm which provides a suitable microenvironment for planted tree growth (Lundmark-Thelin & Johansson, 1997;Luoranen & Rikala, 2013). Other applied methods include spot mounding, which is done by excavating soil and turning it over next to the newly made pit, thereby creating a place where mineral soil is exposed and the tree seedling can be planted (Celma et al, 2019). Spot mounding is more appropriate in areas with heavy precipitation and high water table, because newly made pits collect excess water and prevent tree seedlings from being drowned in high water table conditions, as well as provide water reserves for the drier periods (Gemmel et al, 1996;Heiskanen et al, n.d.;Nieminen et al, 2012).…”

Tree logging significantly impacts environmental conditions, increases soil and air temperature, and changes the microclimate and soil hydrology. This contributes to the changes in bryophyte and vascular plant cover and species composition. Site preparation positively affects the growth of planted trees in young stands but also creates forest understorey disturbance. During site preparation in young stands by spot mounding and disc trenching methods, new microtopographies e.g. soil uplifts and hollows—are made in young stands. Site preparation generally increases vascular plant diversity, but there is a lack of information about the vegetation differences between microtopography depending on different site preparation methods and soil types. The aim of this study was to investigate how the microtopography created during site preparation by spot mounding or disc trenching affects bryophyte and vascular plant communities in hemiboreal young stands two to three years after tree logging. Spot mounding altered vegetation composition more than disc trenching. Bryophyte species cover decreased in prepared soil, but Ellenberg’s Moisture value increased; therefore, site preparation before planting contributes to the conservation of typical forest bryophyte species in young stands. Hollows lead to better typical forest habitat species preservation, but soil uplifts diversify environmental conditions by providing new patches for the development of grassland habitat species that are not typical in this ecosystem, but temporally provide new ecosystem services.

“…Soil temperature and water availability are among the main factors determining the distribution pattern and growth of the roots, and it is one of the most important conditions for plant growth and survival (Grossnickle, 2005). Also soil preparation method has impact on root system development and orientation (Celma et al, 2019). For example, in a harsh environment, as in the north of Scandinavia, soil temperature is one of the main abiotic factors determining the growth of trees (Nilsson et al, 2010) These factors can be affected differently by chosen soil preparation method.…”

The success of the forest regeneration with planting is determined by many factors and one of them is soil preparation. Chosen soil preparation method impacts different environmental aspects and one of them is soil temperature and that is one of main abiotic factors determining the growth of roots. Development of the root system is a key prerequisite for growth of newly planted trees. The aim of this research was to assess the impact of the soil preparation method on the surface (5 and 20 cm) temperature of the soil. T he study was done in 8 young stand sites with different soil preparation methods, soil preparation design (orientation relative to cardinal points) and different forest types in central and northwestern part of Latvia. Soil temperature measurements were taken at 5 cm and 20 cm depths in both sides of furrows and in spot mounds at every study site with hand held thermometer, in few young stands unprepared soil temperature was also measured. Mean values and standard error were calculated and the statistical significance was deter mined by: the Shapiro-Wilk normality test, the Kruskal-Wallis Test and pairwise Wilcoxon test with a 95% confidence level. Our results show that soil preparation positively impact soil temperature compared to unprepared soil and soil temperature in spot mounds was significantly higher than in furrows during clear and hot (27-32°C) day at both depth and in overcast weather with moderate air temperature (20-23°C) in depth of 20 cm.
