this study aimed to determine the effect of land use changes from rangeland to horti-agricultural lands on the most important qualitative characteristics of soil such as total soil carbon and particulate organic matter, in salavatabad region, sanandaj. in the present study, one rangeland, two cultivated pea lands, two cultivated wheat lands and two gardens were selected in growth season in the ...
Land degradation by soil erosion and landslides has been recognised as a constraint for sustainable land-use in Eastern Bhutan for a few decades. However, the extreme diversity in agro-ecological zones, the relative inaccessibility of the region, the lack of reliable data and the limited research capacity made it very difficult to develop a relevant land management strategy. To address this iss...
Land consolidation changes the land use types and then the biomass. The measure and calculation of biomass fore-and-aft land consolidation worked out by the sample plot method in terms of arbor, shrub, herbage plants and crop. The result shows that the biomass is increased 580 t after land consolidation, meaning the impression of land consolidation is remarkable in general. The results of monom...
Abstract A decrease in interest rate traditional view of monetary policy transmission is linked to a lower cost borrowing which eventually results into greater spending investment and bigger GDP. However, also income which, turn, affects the aggregate demand total So far, no concerted effort has been made investigate this positive inter-relation between GDP existing literature. Here first place...
non-point pollution are an important factor in determining water quality and eutrophication of fresh water. the principle causes of this issue is high concentrations of nutrients in the water especially nitrogen and phosphorus. change of land use particularly affected on water nitrate load. therefore, understanding the correlations between land use and nitrate pollutant is a priority in order t...
Nutrient loading into rivers is generally increased by human-induced land-use changes and can lead to increased surface water pollution. Understanding the extent to which land-use patterns influence nutrient loading is critical to the development of best-management practices aimed at water-quality improvement. In this study, we investigated total nitrogen (total N) concentration as a function o...
1. INTRODUCTION Historically, Argentina has been among the world leaders in the production and/or export of agricultural products. The main reason for this is that it is a country relatively sparsely populated but richly endowed with natural resources for production agriculture. According to data from the Food and Agriculture Organization (FAO) (FAOSTAT database), in 2006 Argentina accounted fo...
Two geographers specializing in Russian agriculture and rural development present an exploratory essay on the phenomenon of agricultural land abandonment in the countryside of European Russia. A particular focus is on investigating the relative importance of physical conditions (fertility) and proximity to regional population centers in explaining the prevalence of land abandonment. A map depic...
