Well-authenticated information on pineapple plant response to niitrogen constitutes a valuable criterion in commercial fertilizer practices because the amounts and time of their application are determined by the physical appearance of the plants, designated as plant status, as well as by chemical analyses of their tissues. Besides nutrition, physical factors such as light, temperature, and mois...

The incidence of obesity has been increasing exponentially for the last 30 years, and it is posing a major health issue in the US and worldwide. The 2015 reports by the World Health Organization (WHO) and the Center for Disease Control (CDC) in the US indicate that approximately 1.9 billion people worldwide are overweight and more than 600 million are frankly obese, irrespective of genders, rac...

The rapid growth of the economy in China has caused dramatic growth in the industrial and agricultural development in the Yellow River (YR) watershed. The hydrology of the YR has changed dramatically due to the climate changes and water management practices, which have resulted in a great variation in the fluxes of riverine nutrients carried by the YR. To study these changes dissolved nutrients...

Recent scientific data indicate that nanotechnology has the potential to positively impact the agrifood sector, minimizing adverse problems of agricultural practices on environment and human health, improving food security and productivity (as required by the predicted rise in global population), while promoting social and economic equity. In this context, we select and report on recent trends ...

We all are surrounded by and exposed to many chemicals in our personal environment. These chemicals are either naturally occurring or man-made. Such exposures may have profound impact on our health, such as cigarette smoking, excessive alcohol consumption, and abuse of illicit and legal drugs, or they may be necessary for our survival, such as nutrients, disinfectants, fertilizers and fuels. Ho...

The increasing need for food production in subtropical regions likely translates to a need for additional plant nutrients. As a consequence, knowledge of world fertilizer nutrient reserves is of particular relevance to sustainable agriculture in the subtropics. The stewardship responsibilities of agriculture include the wise use of the raw materials from which commercial fertilizers are produce...

In cotton (Gossypium hirsutum L.) production, the amount of fertilizer input along with plant demand for nutrients can be substantial throughout the growing season. Although conventional fertilization has been instrumental in improving cotton yields, there are drawbacks that accompany their use such as nutrient groundwater leaching and surface runoff, substantial amounts of fossil fuel consumpt...
