“…Moreover, researchers have demonstrated that nutrient loss is also attributed to surface water runoff (Ferreira et al, 2018;Wang et al, 2019). For instance, greater vegetation cover and litter contents in red soil region in Southern China were shown to reduce the concentration of nitrogen and phosphorus in surface water, and hence surface runoff (Chu et al, 2019;Liu et al, 2017;Wu et al, 2012).…”

“…(Salleh et al, 1995), researchers have begun to highlight the environmental impacts of Eucalyptus plantation. These include water consumption (Hubbard et al, 2010), soil erosion (Sun et al, 2018), nutrient loss (Wang et al, 2019), pest and disease (Wingfield et al, 2008), biodiversity (Goded et al, 2019), soil quality (Blanco-Moure et al, 2016) and hydrology (Ferraz et al, 2019). Currently, there is still a lack of research on the issue possibly due to insufficient fund to conduct studies or even lack of interest.…”

Development of forest plantation is mainly intended to provide income opportunity and to ensure the improvement of the socioeconomics of society. Sabah Softwood Berhad (SSB) is one of the private companies that pioneered the development and commercialization of fast growing timber species and forest plantation. The Eucalyptus plantation in SSB was initiated in response to the emergence of fungal disease that implicated the environment. Nevertheless, the impacts of plantation to the environment regarding water use, soil erosion, nutrient loss, pest and disease, biodiversity, soil quality and hydrology are reviewed. The disputes among various scientists over the physiological and plantation aspects of Eucalyptus, especially their implication towards the environment are also discussed. This paper aims to present information on the impacts posed by the Eucalyptus plantation that will guide the planters and policy makers in facilitating a management plan to mitigate the impacts of this species to the environment.

“…The intensities of these changes depend, among other things, on the type of soil to which the conversion is applied. Plant cover is another factor that greatly influences soil erosion, reducing the intensity of runoff and soil losses when plant cover increases (Chowaniak, Klima, & Niemiec, 2016;Klima & Wiśniowska-Kielian, 2006;Wang, Wu, Yin, & Xie, 2019). Nevertheless, the process related to organic carbon losses in the context of erosion and soil tillage is an issue that continues to preoccupy researchers.…”

Soil organic matter plays a key role in determining soil physical and chemical properties, porosity, availability of nutrients and cation exchange capacity (Bellanger et al., 2004; Lal, 1999). The basic sources of organic carbon include decomposing dead plant and animal matter in the soil, root exudate from plants and, importantly, fertilizers, including manure (Mahmoodabadi & Heydarpour, 2014). Losses are in turn associated with the mineralization of organic carbon and its transformation into carbon dioxide gas (CO 2). According to Van Oost et al. (2007), 26% of organic carbon transported during erosion-related processes escapes from the soil into the atmosphere. Another very important element related to the extraction of carbon and the degradation of soil is the process of water erosion. The transport of organic carbon with eroded materials poses a serious problem, particularly for arable land, which becomes more susceptible to runoff and soil losses after being subjected to intensive cultivation. In addition, the loss of organic carbon in dissolved or particulate forms may have severe consequences not only on the soils from which it is exported but also on the water

“…An effective way to control nitrogen leaching in irrigated farming is to optimize irrigation management because controlling the irrigation amount and frequency will effectively limit the amount of water moving out of the active rooting area, thus reducing nitrogen leaching loss 16,17 . However, in the black soil area, almost all farmland is rain-fed farming 18 , and optimized irrigation is not an option for controlling nitrogen leaching in the region.…”

“…The use of agricultural machinery and the no-tillage mode can lead to an increase in the degree of soil compaction; hence, some farmers are ploughing the land before sowing to soften the topsoil. After ploughing, the soil roughness, porosity and water storage capacity increase 18 , which can significantly inhibit surface runoff, and the sediment yield after ploughing decreases by more than 40% compared with no tillage 19 . The soil is loose, and the bulk density decreases after ploughing; however, whether it aggravates the vertical transport of nitrogen and increases the risk of groundwater pollution remain unclear.…”

Considering the large amount and high frequency application of concentrated fertilizer nitrogen in the Black Soil Region of Northeast China, the current laboratory/field simulation study aimed to explore the pollution risk of added nitrogen in black soil to groundwater and identify effective measures to prevent and control soil nitrogen leaching with an undisturbed soil column. The results showed that the saturated nitrogen adsorption capacities increased by 1.7%, 7.7% and 18.5% in ploughing, impervious agent (starch grafted polyacrylic acid) addition, and corn straw returning treatments, respectively, relative to the control (no-till). When the collection volume of the leaching solution reached the experimental maximum (4,000 mL), the total amount of nitrogen leaching from the control soil column (i.e., the no-tillage treatment) accounted for more than 50% of the added nitrogen, indicating a great risk of nitrogen pollution in groundwater. Compared with the no-tillage treatment, the amount of nitrogen leaching from the ploughing treatment increased insignificantly, and the amount of nitrogen leaching in the following spring in the corn straw returning treatment increased by 11.2%. The amount of nitrogen leaching decreased by 12.5% in the soil sampled in autumn of the second year. The total amount of nitrogen leaching in the soil with impervious agents decreased by 40.1%. Therefore, the permeability-reducing agent could significantly reduce underground water pollution risk posed by nitrogen leaching.
