We evaluated the effect of saw dust ash (SDA) and poultry droppings (PD) on soil physico-chemical properties, soil carbon and nitrogen stock and their effects on the growth and yield of okra (Abelmoshus esculentus) on a typic haplusult in Owerri, Imo Stat... see more

Quantification the effect of agricultural cropping systems on soil carbon and nitrogen is important to farmers and policymakers because of its importance to climate change mitigation and improving soil quality and productivity. This is very important in t... see more

The emissions of greenhouse gases (GHGs) in an oil palm plantation associated with land use change have been evaluated on a site-specific basis. Nitrous oxide (N2O) emissions from the application of nitrogen fertilizers during the growth stages of the pal... see more

Sustainable forest management should avoid disturbance and volatilization of the soil carbon (C) and nitrogen (N) stocks both under present and projected future climate. Earlier studies have shown that thinning of European beech forests induces a strong i... see more

As in any agroecosystem, also in aquaponics the nitrogen (N) balance represents an important tool to evaluate sustainability, and to identify factors that can improve N use efficiency (NUE) and reduce N losses. In this respect, fish stocking density has b... see more

Previous studies have focused on carbon (C) and nitrogen (N) stocks of soils because of increases in atmospheric carbon dioxide (CO2) and terrestrial ecosystems with wide N storages. The goal of this study is to determine C amounts and stocks that are imp... see more

Permasalahan yang dihadapi pembudidaya ikan dengan sistem intensif adalah meningkatnya limbah yang terakumulasi pada air dan sedimen. Limbah budidaya ikan pada umumnya berupa padatan dan nutrien terlarut pada air terutama nitrogen dan fosfor. Tujuan penel... see more

This experiment was carried out to determine the optimum C/N ratio for heterotrophic bacteria (biofloc) growth in order to control nitrogenous waste accumulation in the catfish (Clarias gariepinus) culture. Twenty fish with an initial individual... see more

Soil total nitrogen (N) stock in rangelands, shrublands, and forests support key ecological functions such as the capacity of the land to sustain plant and animal productivity and ecosystem services. The objective of this study was to model soil total N s... see more
