An alternative technology for removal of nutrients released from mariculture is here suggested. Harvest of cyanobacteria Nodularia spumigena during summer blooms may compensate for release of N and P from mariculture or other sources. Not only content of N in the cyanobacteria but also prevention of N fixation will contribute to nutrient removal from the sea. The harvested product may be used f...

Under the changing climatic conditions, one of most pressing issues in wheat production is improvement yield quality, lack which has a negative impact on animal and human health. More than 25% world’s population are affected by micronutrient deficiencies food products, problem known as hidden hunger. Thus, effective management crucial for improving both quantity quality increasing plant’s abili...

Through the intensive use of fertilizers green revolution has been successful in increasing agricultural production but the spot of ground where the corn and plants grew has changed beyond recognition. In the race of producing more food at any cost, soils in countries like India has badly deteriorated. Industrialization, urbanization and infrastructural developments have reduced agricultural la...

Supplementing the nutrient requirement of crops through organic manures plays a key role in sustaining soil fertility, and crop productivity and reducing use of fossil fuels. Field experiments were conducted for 2 years at two different locations (i.e. Lucknow and Pantnagar) in Uttar Pradesh, India. The objectives of the study were to assess the herb and essential oil yields of Japanese mint (M...

The solanaceous group of vegetables (tomato, eggplant, chili and bell peppers) generally take up large amounts of nutrients. The amount of nutrients they take up depends on the quantity of fruit and dry matter they produce, which in turn is influenced by a number of genetic and environmental variables. For tomato to produce 1 mt of fresh fruit, plants need to absorb, on average, 2.5 to 3 kg N, ...

Based on various characteristics of zeolite, its utilization in the manufacture of fertilizers with slow-release properties is possible. The objectives of this study are to characterize and utilized nitrogen, phosphorus and potassium (NPK) slow release fertilizer by using natural zeolite in Indonesia. In this research, zeolite was utilized as a mixture of Slow Release Fertilizer (SRF). Effect o...

On-farm experiments (24) were conducted in two seasons to assess the influence of sulfur impurity triple-super phosphate (TSP) on wheat. The laid-out completely randomized block design triplicate. Nutrients investigated include: Nitrogen (N), (S) and phosphorus (P). TSP is tested contain about 2 6% as impurity. However, wheat did not show response from TSP. Though, it was statistically signific...

Rural household biogas (RHB) systems are at a crossroads in China, yet there has been a lack of holistic evaluation of their energy and climate (greenhouse gas mitigation) efficiency under typical operating conditions. We combined data from monitoring projects and questionnaire surveys across hundreds of households from two typical Chinese villages within a consequential life cycle assessment (...
