“…In unfertilized soil containing little available nutrients a poor crop cover forms and, therefore abundant precipitation increases infiltration more than in fertilized soil. Positive impact of vigorous vegetation cover on the reduction of rainfall percolation was noted by various scientists (Bellot et al, 1999;Muñoz-Carpena, 2008;Petersen, Stringham, 2008). During autumn and winter periods, as decomposition of plant residues incorporated into soil proceeds, precipitation infiltration in fertilized soil remained lower (6.7-11.0% and 19.2-23.4%, respectively) compared to unfertilized soil, but in spring the differences almost disappeared.…”

The aim of the work was to evaluate the effect of different forms (granular or liquid) of nitrogen fertilizers on nitrate concentration and nitrogen leaching from a sandy loam Haplic Luvisol (LVh), to identify precipitation infiltration differences in fertilized and unfertilized soils. It was revealed that fertilization with nitrogen (on average 120 kg ha -1 N), compared to the unfertilized soil, increased the average annual nitrate concentration in leachate by 37.5-54.3% (P < 0.05). Slightly higher nitrate concentration was revealed after application of liquid fertilizer UAN 32. Compared to unfertilized soil, the impact of fertilizers on the increase of nitrate concentration in leachate was significant during summer (by 6.2-40.4 mg L -1 NO 3 ; P < 0.05) and autumn (by 32.2-52.3 mg L -1 NO 3 , or 49.8-80.8%; P < 0.05). Nitrogen leaching from nitrogen-fertilized soil increased by on average 6.3-9.5 kg ha -1 N per year, as compared with the unfertilized soil. Compared with ammonium nitrate and liquid complex fertilizer Lyderis 9-9-9, significantly more nitrogen (by 2.7-3.2 kg ha -1 N; P < 0.05) was leached from the soil applied with liquid fertilizer UAN 32. An average of 6.0-8.9% of applied nitrogen fertilizer content was leached per year. Thicker and more vigorous crops formed in fertilized soil, this reduced the average rainfall infiltration by 13.7-16.2% per year and by 31.6-38.8% during summer period, compared with unfertilized soil. This reduced the overall nitrogen leaching losses resulting from application of fertilizers.

“…From this information we can gather that soil treatment improves the growth during afforestation [7,22,30] and such growth is important to protect against erosion and to reduce runoff lamination [26,27] as there is an increase in the vegetable cover thanks to the planting of the pines [3,23], without the original species having been eliminated.…”

“…The main limiting factor in the Mediterranean climate is the lack of water, especially during the summer months [3,10,19,29]. This is the reason why the introduction of seedlings linked to the site preparation focused on concentrating runoff water on the seedling bed can not only improve the afforestation and avoid its failure [2,9] but also increase the afforestation growth [12,30].…”

-A forested area at the Sierra de Gador, Almería, Spain, was afforested with Aleppo pine (Pinus halepensis Mill.) 13 years ago using a technique never before used in Europe for forested areas: banks with micro-basins. This technique is compared in our study to the banks without micro-basins, both in sunny and shady slopes. It is also analysed whether this site preparation modifies the specific composition of the pre-existing vegetation. The average height of the pines planted on shady plots with micro-basins is 3.06 m whereas in shady plots without micro-basins the average height is 2.37 m, in sunny slope average height are 2.52 m compared to 1.61 m with and without micro-basins. These differences are significant, as are the ones in diameter: 11.1 cm compared to 8.5 cm in the first case and 11.0 compared to 7.0 cm in the second. Micro-basins supply possibly enough water to the banks so that the annual increase of the growth rings does not depend on the rainfall, not even during a particularly dry year. In plots without micro-basins there is a close relationship between the annual trunk growth and the spring rainfall. Using a multivariate analysis it is shown that neither land removal or a change in the hydric accumulations affect the composition of the preexisting vegetation.micro-basins / site preparation / semiarid / Pinus halepensis / soil compensation Résumé -Effets de la préparation du terrain sur des micro-bassins dans des reboisements de Pinus halepensis Miller en conditions de climat semi-aride. Un reboisement avec du pin d'Alep a été réalisé en 1988 dans une région forestière de la chaîne de montagnes espagnole de Gâdor, Almeria. Cette opération a utilisé pour la première fois en Europe la technique de « la banquette de micro-bassins ». On peut comparer l'effet de cette technique avec celle des banquettes sans micro-bassins à l'adret ou à l'ubac de vallées sur la croissance des pins et sur la composition spécifique de la végétation. La hauteur moyenne des pins des parcelles à l'ubac était de 3,06 m avec microbassins et de 2,37 m sans micro-bassins. Dans les parcelles à l'adret, la hauteur moyenne était respectivement de 2,52 et de 1,61 m. Les différences sont également significatives pour les diamètres à l'ubac, soit 11,1 cm contre 8,5 cm respectivement avec et sans microbassins, et à l'adret 11,0 contre 7,0 cm. Les micro-bassins fournissent l'eau nécessaire à la banquette pour que la croissance annuelle des arbres ne soit pas dépendante des précipitations, même lors d'une année sèche. En revanche, il existe une corrélation entre l'accroissement annuel du tronc et les précipitations du printemps dans les parcelles sans micro-bassins. Les analyses multifactorielles ont montré que ni le terrassement ni le changement des flux hydriques ne modifient la composition spécifique de la végétation. micro-bassins / préparation du terrain / semi-aride / Pinus halepensis / compensation du sol

“…Discharge to the Bulang River increases slightly with increasing net recharge, while deep groundwater circulation discharging to the Hailiutu River remains constant. The benefit of increasing net recharge is largely in increasing groundwater storage, especially in scenarios (1) and (4). Increase of discharge to the Bulang River and increase of groundwater levels occur in the growing period from mid April to mid September (Figure 12).…”

“…Along with the water shortage limitation for agricultural productivity, the desertification has been controlled by planting shrubs as ecosystem rehabilitation measures in recent decades in the semi-arid parts of northwest China [3]. However, the water balance in semi-arid catchments can be significantly influenced by vegetation type [4], irrigation schedules [5], and groundwater irrigation [5]. Brown et al [6] determined that the changes in water yield at various time scales were a result of permanent changes in the vegetation cover by means of mean annual water balance model.…”

Abstract:Groundwater is the most important resource for local society and the ecosystem in the semi-arid Hailiutu River catchment. The catchment water balance was analyzed by considering vegetation types with the Normalized Difference Vegetation Index (NDVI), determining evapotranspiration rates by combining sap flow measurements and NDVI values, recorded precipitation, measured river discharge and groundwater levels from November 2010 to October 2011. A simple water balance computation, a steady state groundwater flow model, and a transient groundwater flow model were used to assess water balance changes under different land use scenarios. It was shown that 91% of the precipitation is consumed by the crops, bushes and trees; only 9% of the annual precipitation becomes net groundwater recharge which maintains a stable stream discharge in observed year. Four land use scenarios were formulated for assessing the impacts of land use changes on the catchment water balance, the river discharge, and groundwater storage in the Bulang catchment. The scenarios are: (1) the quasi natural state of the vegetation covered by desert grasses; (2) the current land use/vegetation types; (3) the change of crop OPEN ACCESSWater 2015, 7 5960 types to dry resistant crops; and (4) the ideal land use covered by dry resistant crops and desert grasses, These four scenarios were simulated and compared with measured data from 2011, which was a dry year. Furthermore, the scenarios (2) and (4) were evaluated under normal and wet conditions for years in 2009 and 2014, respectively. The simulation results show that replacing current vegetation and crop types with dry resistant types can significantly increase net groundwater recharge which leads to the increase of groundwater storage and river discharges. The depleted groundwater storage during the dry year could be restored during the normal and wet years so that groundwater provides a reliable resource to sustain river discharge and the dependent vegetations in the area.
