ABSTRACT- To study the effect of tree roots on increasing water infiltration in soil and also to determine and assess the coefficients of different infiltration models, some infiltration tests were performed in three tree plantation areas in Badjgah, Fars province with different soil textures (clay loam for pear plantation, sandy loam for grape plantation, loamy sand for pine trees). In each pl...

cially in homogeneous, even-aged plantation scenarios. Airborne imagery has mainly been used for detection of individual trees using local maxima filtering, as point spread function and signal-to-noise ratio are smaller than with satellite-borne imagery. This led to the development of a novel approach to local maxima filtering for tree detection in plantation forests in KwaZulu-Natal, South Afr...

The quantitative performance of wheat crop under 1-5 year old poplar plantations in irrigated agro-ecosystem was studied to ascertain the biological yield of tree and crop. Results revealed that growth and yield of wheat decreased significantly with the increase in poplar age. The per cent reduction in net grain yield was 17% under one year old poplar plantation, which increased to 52.15% under...

In desertified regions, shrub-dominated patches are important microhabitats for ground arthropod assemblages. As shrub age increases, soil, vegetation and microbiological properties can change remarkably and spontaneously across seasons. However, relatively few studies have analyzed how ground arthropods respond to the microhabitats created by shrubs of different plantation ages across seasons....

BACKGROUND In a semi-arid ecosystem, water is one of the most important factors that affect vegetation dynamics, such as shrub plantation. A water use strategy, including the main water source that a plant species utilizes and water use efficiency (WUE), plays an important role in plant survival and growth. The water use strategy of a shrub is one of the key factors in the evaluation of stabili...

objective: ecosystems with mixed species compared to the ones with pure compositions provide a broader range of options in the fields of biodiversity, conservation, protection and restoration. nearly all forest plantations are established as monocultures, but research has shown that there are potential advantages to be gained by using carefully designed species mixtures in place of monocultures...

carbon sequestration in soil, leaf and litter of three tree species, viz. eucalyptuscamaldulensis, prosopisjuliflora and ziziphus spina-christi, plantation was investigated in the dehloran city, iran. results showed that the amount of sequestered c in leaf, litter and soil was significantly different among these species. the highest amount of sequestrated c was in leaf and the lowest amount in ...

gauge instrument or prism was introduced, which significantly expedited the process. There was no national forest resource information in China during 1963–1972. The first NFI was performed during 1973–1976, in which a stratified systematic sampling technique was used to locate NFI sample plots. Each province, autonomous region, or municipal city designed one or more sampling populations accord...

understanding the relationship between soil and plant is essential for reclamation of degraded lands. in order to investigate the relationship between atriplex halimus density with carbon sequestration the rangeland of incheborun was studied. soil samples were collected randomly by auger in the depth of 0-30 cm of the soil profile in three different plant densities (400 stand per hectare) with ...

the aim of this study was to develop an optimal sustainable forest plantation based on goal programming and analytic hierarchy process (ahp) methods. this study was carried out in guilan province, north of iran. first of all, the ecological capability of the study area for plantation establishment/maintenance was evaluated based on multi-factor method and specific ecological makhdoum model by m...
