The actual Mg budget is negative even with no biomass use. For the beech stand, sustainibility can be achieved at a higher level of biomass utilization because of a better nutrient availability due to deeper rooting. As a consequence of negative nutrient budgets ...

Global Climate Change
In addition to its affects on wheat's growing season and rate of photosynthesis, elevated temperature can affect soil moisture, bacterial disease and fungal growth, insect infestation, and nutrient availability. All of these factors affect wheat yield. Elevated temperatures may dry out the soil, and thus decrease the amount of water available to the wheat. If the wheat does not ...

Restoring Ecosystem Health in Ponderosa Pine Forests of the Southwest (page 1 of 2)
As a result of these changes in forest composition and structure, there has been a significant decrease in 1) soil moisture and nutrient availability, 2) growth and diversity of both herbaceous and woody vegetation, and 3) stream and spring water flows due to less soil absorption of precipitation. There has also been a marked increase in mortality of old-growth ...

Sea Sediments
For example, by studying the chemical composition of plankton shells, we can reveal information about past seawater temperatures, salinity (saltiness), and nutrient availability. Indeed, such techniques have been used to reconstruct ocean temperatures over the last 100 million years, and have confirmed continental drift theories of climate change that a ...

FAO/AGL - Soil Biodiversity Portal
The activities of this wide range of soil biota contribute to many critical ecosystem services, including: soil formation; organic matter decomposition, and thereby nutrient availability and carbon sequestration (and conversely greenhouse gas emissions); nitrogen fixation and plant nutrient uptake; suppression or induction of plant diseases and pests; and bio ...
