“…Two soil moisture sensors were installed at each depth of 5, 10, and 15 cm. However, soil moisture at 30 cm depth was monitored by one soil moisture sensor because soil moisture in subsoil was less sensitive to changing environmental conditions than topsoil ( Rong et al, 2017 ). Rainfall (mm) was measured by tipping rain gauge bucket (TE525MM-PT; Campbell Scientific).…”

Background Southeast Asia has experienced widespread deforestation and change in land use. Consequently, many reforestation projects have been initiated in this region. However, it is imperative to carefully choose the tree species for planting, especially in light of the increasing climate variability and the potential alteration of plantation on the watershed water balance. Thus, the information regarding water-use characteristics of various tree species and sizes is critical in the tree species selection for reforestation. Methods We estimated tree water use (T) of dominant species including Syzygium antisepticum and Adinandra integerrima, hereafter Sa and Ai, respectively, in a secondary tropical forest in Khao Yai National Park, Thailand, using sap flow data, and compared T between species and size classes. Additionally, we evaluated the responses of T of both species in each size class to environmental factors including soil moisture and vapor pressure deficit (VPD). Results Results showed consistently higher T in Sa compared to Ai across ranges of VPD and soil moisture. Under low soil moisture, T of Sa responded to VPD, following a saturating exponential pattern while Ai maintained T across different VPD levels, irrespective of tree size. No responses of T to VPD were observed in either species when soil water was moderate. When soil moisture was high, T of both species significantly increased and saturated at high VPD, albeit the responses were less sensitive in large trees. Our results imply that Ai may be suitable for reforestation in water-limited areas where droughts frequently occur to minimize reforestation impact on water availability to downstream ecosystems. In contrast, Sa should be planted in regions with abundant and reliable water resources. However, a mixed species plantation should be generally considered to increase forest resilience to increasing climate variation.

The paper presents the problem of the growing water deficit and the possibility of sustainable development of water resources in rural areas of Central and Eastern Europe (using the example of Poland). It is estimated that the amount of resources in this region is reduced by about 70% compared to the average for Europe. In drought periods it comes to limitation of economic activity, including agriculture. Particular attention was paid to the necessity to extend landscape, underground, and snow retention, as an alternative to dams, which are currently the most popular in lower-order catchments. It has been shown that the construction of small agricultural reservoirs is not always preceded by adequate consultations and pre-design studies, which may result in financial losses and legal problems. Simultaneous use of many alternative forms of retention should be more effective than the implementation of reservoirs. In addition, increasing the hydraulic roughness of the catchments slows down the outflow of products of erosion and contributes to the protection of surface retention structures (maintaining natural and economic usefulness of reservoirs).

“…Moisture availability is an important soil property for plant growth and maintaining the sustainability of agricultural ecosystems . It is affected by clay and organic matter contents rather than other soil property (Ding et al, 2014 andRong et al, 2017). According to Riquier et al (1970) moisture availability in soil is determined by available water that seems in the current study to be above PWP and below FC, and hence moisture content rating is 100.Concerning mineralogy, Wahab & Stanley (1991) and Abdou & Shehata (2009) indicated that the area is covered by deposits of weatherable rock-derived minerals of igneous, metamorphic, and sedimentary rocks.…”

THE GROWING demand for food with a simultaneously increased population raised the pressure on land and soil resources. Hence, monitoring their productivity enable refining management practices in order to improve the performance. The current work aimed at evaluating spatial and temporal variations in the productive capacity of 2157.65 km 2 (215765 ha) located along the Nile River (Damietta branch), Egypt. The soils belong to three productivity classes; grade I (excellent), grade II (good) and grade III (average), representing 4.6, 79.3 and 16.1%, respectively of the total area. Changes in the land productivity were observed during the last five decades. The positive changes are predominant in the majority of the studied soils (76%), while the negative changes are in few localities (24%). Excessive salt content, improper drainage conditions and texture/structure are the most effective limiting factors. Improving land productivity grade requires improving drainage conditions, leaching excessive salt, and addition of organic amendments.
