Background: Although Americans receive almost a quarter of their daily energy from snacks, snacking remains a poorly defined and understood eating occasion. However, there is little dietary guidance about choosing snacks. Families, clinicians, and researchers need a comprehensive approach to assessing their nutritional value. Objective: To quantify and compare the nutrient density of commonly c...

Suboptimal N or P availability and cool temperatures all decrease apparent hydraulic conductance (L) of cotton (Gossypium hirsutum L.) roots. The interaction between nutrient status and root temperature was tested in seedlings grown in nutrient solutions. The depression of L (calculated as the ratio of transpiration rate to absolute value of leaf water potential [Psi(w)]) by nutrient stress dep...

The parties involved in trading feed grains and other feed materials are normally aware of the relationships of the difference of their external appearance with their nutrient composition and usefulness. Several reports are available on nutrient composition of DDGS and its nutritional evaluation in different animal species. Some manufacturers and the University of Minnesota have published data ...

______________________________________________________________________________ Abstract: Information on soil and leaf nutrient concentrations for black walnut are of value only when they are properly sampled, accurately analyzed, and the results correctly interpreted. Guidelines for interpreting soil and leaf analyses and leaf symptoms are presented along with recommendations for correcting nut...

Distillers dried grains with solubles (DDGS) is produced from the fuel ethanol industry and is available for inclusion in diets fed to swine. During recent years, several research projects have been completed to investigate the feeding value of DDGS. Crude nutrient concentrations, energy and nutrient digestibility values, and effects of including DDGS in diets fed to different categories of swi...

Ecosystem services are defined as those functions of ecosystems that support (directly or indirectly) human welfare. They occur at multiple scales, from climate regulation and carbon sequestration at the global scale, to flood protection, soil formation and nutrient cycling at local and regional scales (Kremen 2005; Table 1). The MIMES project aims to integrate participatory model building, dat...

The mathematical methods for optimising the effects of heat processing food products are reviewed in relation to microbial destruction, nutrient destruction, cooking value and loss of quality. Some data are presented for the kinetics of the various thermal effects. The results obtained by various workers are presented with particular reference to nutrient retention.

hydroponics technique accompanied by adjustment of nutrient solution seems to optimize crop production and help in establishing sustainable agriculture. in recent years, the greenhouse production of cucumber has been increased in iran, however there are just a few proper nutrient solutions employed in growing the crop. in line with this, an experiment was conducted to find the effect of various...

Dryland salinity is a major problem affecting food production from agricultural land in Australia and throughout the world. Although there is much interest in using saline groundwater to grow marine fish on salt-affected farmland, the disposal of nutrient enriched, saline aquaculture effluent is a major environmental problem. We investigated the potential of the salt-tolerant NyPa Forage plant ...

Recycling is generally thought of as an attempt to close a material loop with an additional input of energy. That is, by nature’s own model, discarded mixed materials are restored to their original pure condition for re-use. Economically minded people recycle when the value of the reclaimed materials exceeds the cost to capture and restore them. Ecologically minded people recycle to conserve re...
