An investigation was conducted to analyse the distribution of available plant nutrients and examine relationships between soil properties nutrient status in profiles Eastern India. Three were exposed under three different topographic positions. In all pedons, reaction (pH) increasing EC very nominal because there is no accumulation dissolved salts pedons. The N decreasing with depth phosphorus ...

2 Postdoctoral Researcher, University of California, Irvine, Calif. Abstract: The frequent fires in southern California have a pronounced influence on many aspects of chaparral shrub communities, particularly nutrient relationships. Nutrient accumulation, and productivity were studied for the post fire species Lotus scoparius. This stand of Lotus scoparius was approaching maximum biomass yet th...

When crop plants are subjected to soil waterlogging, or an anaerobic condition, their root and shoot systems respond differently. A variety of morphological and anatomical alterations develop in the root system. Reduction of the root respiration rate has been reported in both flooding-tolerant and intolerant species. Besides alcoholic fermentation, several diverse fermentative bypasses take pla...

The sugar, starch, and fructan content (collectively referred to as nonstructural carbohydrates [NSC]) of pasture plants is dependent on the environmental conditions under which they have grown. Pasture that is stressed by cold, drought, or lack of nutrients can be 2 to 3 times higher in NSC than pasture that grows quickly in warm weather and is adequately watered and fertilized. Horses at risk...

Zoogloea ramigera 115 synthesized large amounts of matrix polymer from fructose, galactose, glucose, lactose, mannose, soluble starch, and sucrose when these carbohydrates were used as supplements to a chemically defined medium. All of them supported polymer synthesis to the extent that cultures thickened to a gel. Concentration of carbohydrate nutrients in the range 0.5 to 2.0% was not a criti...

Consumers must regulate the elemental composition of body tissue at ratios that differ from those of their food. This problem of elemental homeostasis is especially acute for herbivores for which elemental composition of food does not equal that of the consumer and changes widely throughout the lifespan. We extend work of Sterner [1] and Frost & Elser [2] using a dynamic model of homeostatic co...
