Soil salinity and nutrients pattern along a distance gradient in coastal region
Soil salinity is considered as one of the major challenges in coastal agriculture in Bangladesh yet geographical extent of soil salinity and nutrients status have received little or no attention. This study investigated the patterns of soil salinity, total nitrogen, phosphorous, potassium and sulfur between agricultural and fallow land along a 90 km distance from the coastline in Noakhali, Bang...
متن کاملFood security: increasing yield and improving resource use efficiency.
Food production and security will be a major issue for supplying an increasing world population. The problem will almost certainly be exacerbated by climate change. There is a projected need to double food production by 2050. In recent times, the trend has been for incremental modest yield increases for most crops. There is an urgent need to develop integrated and sustainable approaches that wi...
متن کاملNutrient removal efficiency by floating macrophytes; Lemna minor and Azolla pinnata in a constructed wetland
The use of constructed wetlands for purifying pre-treated wastewater is a cost effective technology that has been found to be more appropriate for many developing countries. The technology is also environmentally friendly with the wetlands being habitats for many water birds and other aquatic organisms. This study assessed nutrient removal efficiency of two floating macrophytes (Lemna minor...
متن کاملnteraction of nutrient resource and crop diversity on resource use efficiency in different cropping systems
introduction conventional operations in fields, soil and water management are not efficient and loss of and damage to the environment are considerable (lal, 2000). crop diversity and understanding the complex interactions between environmental and socioeconomic factors are approaches to make better use of limited resources (tengberg et al., 1998). the most diverse ecosystems have a higher produ...
