Influence of Improved Pastures and Grazing Animals on Nutrient Cycling within New Zealand Soils
The improvement of New Zealands pastures over the last ISO years has increased the nutrient status of the soil as a result of the application of fertiliser, an increased soil organic matter content and increased biological activity. The grazing animal has also influenced the nutrient status of the soil by increasing the rate at which nutrients cycle between the soil, plants and animals. However...

15 صفحه اولCadmium Accumulation by Forage Species Used in New Zealand Livestock Grazing Systems
Little data exists on cadmium (Cd) accumulation in many plant species now commonly used as animal forages in New Zealand livestock grazing systems. A glasshouse trial was undertaken on 12 forage species to address this knowledge gap. Mean tissue Cd concentration decreased in the order chicory > plantain > turnip > lucerne > sheep’s burnet > strawberry clover > kale > perennial ryegrass > haresf...
متن کاملInvestigating Causes of Population Decline in New Zealand Plants and Animals: Introduction to Symposium
The four steps we must take to identify why a species is declining and what can be done about it begin with a natural history study to select correct hypotheses about the likely causal agent (Caughley, 1994). For most readers, this will seem so immediately obvious as not to need page space, but the implication that there are incorrect hypotheses we might erect has been a painfully learned lesso...
متن کاملDiversity of Plants and Animals in Mountain Ecosystems in Tajikistan
Tajikistan is a hotspot of plant and animal species diversity and endemism andis important for the conservation of biodiversity on a global scale. The country is located ata biological crossroads. Species from Central and Northern Europe, Central Asia, theMiddle East, and North Africa mingle here with endemics found nowhere else. Therichness of Tajikistan‘s biodiversity shows up at the genetic,...
