Modeling Nutrient Supply to Ruminants: Frost-damaged Wheat vs. Normal Wheat
Frost Damaged Wheat Modeling Nutrient Supply Ruminants
2016/5/4
The objectives of this study were to use the NRC-2001 model and DVE/OEB system to model potential nutrient supply to ruminants and to compare frost damaged (also called “frozen”) wheat with normal whe...
Verifying the Limited Nutrient Supply Control Based on the Nutrient Uptake Pattern of Muskmelons Grown in Substrate Culture Using a Double Trough Bed
EC-based control interveinal chlorosis quantitative nutrient control soilless culture
2010/11/24
To verify the possibility of growing muskmelons by limited nutrient supply control (LNSC) based on the changing pattern of nutrient uptake, muskmelons were grown in double trough substrate bed from Ap...

EC-based control method nutrient uptake characteristics substrate culture
2010/11/24
Limited nutrient supply control of tomato grown in substrate culture using a double trough bed was investigated. Two experiments were conducted to determine the effect of a reduced amount of nutrient ...
Nutrient supply for organic oilseed crops, and quality of potential organic protein feed for ruminants and poultry
Oilseed crops concentrates oilseed cake pea rape turnip rape camelina
2010/1/19
The aim of organic farming husbandry is to be entirely based on an organically

Agronomic efficiency internal nutrient use efficiency maximum accumulation maximum dilution
2009/3/4
So far, application of fertilizer to mitigate problems of nutrient-limited yields in farmers’ fields in the Highlands of Ethiopia has been based on conventional blanket fertilizer recommendation...
Temperature and nutrient supply interact to control nitrogen fixation in oligotrophic streams: An experimental examination
Temperature and nutrient supply control nitrogen fixation oligotrophic streams
2014/5/5
We performed two experiments to examine how temperature and nutrients interact to control dinitrogen (N2) fixation, chlorophyll a (Chl a) biomass, and community composition of periphyton in subalpine ...
The importance of submarine groundwater discharge to the near shore nutrient supply in the Gulf of Aqaba (Israel)
submarine groundwater discharge near shore nutrient supply the Gulf of Aqaba
2014/5/4
We used two short-lived radium isotopes (223Ra, 224Ra) and a mass balance approach applied to the radium activities to determine the nutrient contribution of saline submarine groundwater discharge to ...
Physical pathways of nutrient supply in a small, ultraoligotrophic arctic lake during summer stratification
Physical pathways nutrient supply
2014/5/4
During the ice-free period in the Arctic, the thermal structure and mixing dynamics of small lakes change with the passing of air masses. In Toolik Lake, Alaska, stable warm air masses during the ice-...
