In order to achieve the goals of sustainable agricultural and rural development, education is an issue that should be in base considered researched according importance its related challenges must realistically analyzed, Since water one effective factors sector plays a vital role production products. There are several for low productivity country, which can non-optimal unplanned use water. It c...
Shifting cultivation (jhum cultivation), a common practice of converting forest land into agricultural by slash and burn is threatening the ecosystem. This study assesses effect shifting cycles on soil quality in North-eastern Himalayan region using minimum properties. To achieve this goal, index (SQI) approach multivariate techniques were used for surface (0-30 cm) subsurface (30-70 layers soi...
Nitrogen fertilization ensures the proper growth of trees. The aim study was to evaluate impact differentiated nitrogen on selected parameters. It assumed that such analysis is an indirect picture needs cherries grown in herbicide fallow. content minerals two layers soil, leaves, and its influence tree growth, chlorophyll leaves were assessed. experiments carried out three different cherry orch...
Introduction Land-use planning has three subcategories: allocation, politics and economics. In general, allocation is the interaction between land proportion (supply) and the area required (demand), in current condition of the region. On the other hand, politics is the spatial planning. The economic aspect of land use is dedicated to the fact that in the system of supply and demand in order ...
Broadcast plantings of nonhost cultivars (alfalfa, barley, bean, onion, potato, and wheat) in soil in redwood boxes (4.2 x 30 x 14 cm) infested with Heterodera schachtii reduced the initial nematode populations (P = 0.05). The reduction was greater with sugarbeets, a host, than with all other cropping treatments except onion, bean, and fallow (P = 0.05). After 80 days, when the root growth of a...
Several methods have been proposed for recommendation of phosphorus fertilizers. Each of them only examines the concentration of phosphorus in the soil or plant, while none of them investigates the correlation between phosphorus concentrations in the soil and plant. In this study, a method called "integrated plant and soil system" (IPSS) is proposed to describe phosphorus fertilizer. In this sy...
Protected areas are a relevant conservation tool at our disposal, especially for developing management strategies of natural habitats. However, explicit tests large spatial scales about its effectivity protecting different components biodiversity still rare. This study explored the matching between distribution three avian diversity (taxonomic, functional, and phylogenetic metrics) network Natu...
Knowing the trees nutritional status is necessary for achieving balanced fertilization in orchards. One approach for determining the nutritional status of orchards is the compositional nutrient diagnosis method. In the present research this method was performed to evaluate the nutritional status of three important areas of lime cultivation in Hormozgan province, south of Iran, during 2014 and 2...
The impacts of agro-pastoral activities on soil properties, plus nutritive value and residual standing biomass herbaceous plants in areas different land uses western Serengeti, were evaluated. Vegetation sampled along 4,000 m transects laid across fallow land, grazed only by livestock, mixed grazing (livestock wildlife) wildlife only. A total number 123 plant species encountered during sampling...
Land use change resulting from anthropogenic pressure on land has led to degraded soil quality, especially in the hilly tropical regions where ecosystems are generally fragile and susceptible degradation cultivation. Hence, sustainable uses management practices crucial for agricultural production ecological balance, particularly these regions. The present study investigates impact of various hi...
