We studied the interacting roles of nutrient availability and herbivory in determining the macroalgal community in a rocky littoral environment. We conducted a factorial field experiment where we manipulated nutrient levels and herbivory at two sublittoral depths and measured macroalgal colonization and the following young assemblage during the growing season. At the community level, grazing re...

Soybean is a good source of protein and calories therefore important for food security. yields in small scale farmers field stand at less than 1.0 t ha-1 against potential 3 to 3.6 ha-1. This has been attributed low soil fertility. Although lot work carried out on nitrogen (N) phosphorus (P) nutrition, but research findings indicate that are still low, raising suspicion other nutrients could al...

introduction half of the world's population suffers from micronutrients malnutrition. use of bio-fertilizers in sustainable agricultural systems is important in production and enables plants to absorb more water from soil and improves plant nutrient uptake and photosynthesis. benefits of vermicompost application in agriculture is due to its content of organic matter, plant nutrients and plant g...

Neonate ruminants possess little cell-wall and starch degrading enzyme activity. Importantly, early establishment of fibrolytic, amylolytic, and proteolytic capacities is influential for the early expansion of the reticulorumen epithelia. Such an early development in reticulorumen fermentation will enable a timely hepatic adaptation to volatile fatty acids assimilation. The early nutrient relea...

17 Nitrogen pollution affects many peatlands with consequences for their biodiversity and ecosystem 18 function. Microorganisms control nutrient cycling and constitute most of the biodiversity of peatlands 19 but their response to nitrogen is poorly characterised and likely to depend on the form of deposition. 20 Using a unique field experiment we show that ammonia exposure at realistic point s...
