Sentences with phrase «increase plant growth rates»

This conclusion was based on precise measurements of the atmosphere's O2 / N2 ratio and indicates that the biosphere's response to increasing temperatures is to increase plant growth rates faster than decomposition rates.

On the contrary, there is plenty of evidence that the some 100ppm higher C02 levels are entirely beneficial, increasing plant growth rates substantially.

Not exact matches

Planting the peppers on the south side of ridges that run east and west in the garden will increase the growth rate because the soil facing the sun will be warmer than level soil.

My work is also directed toward determining why plants exposed to elevated carbon dioxide concentrations often have only a temporary increase in growth rate, and toward determining what plant characteristics might be most beneficial to the productivity and to the nutritional value of crops if atmospheric carbon dioxide concentrations continue to rise.

The researchers believe the greening is a response to higher atmospheric carbon dioxide inducing decreases in plant stomatal conductance — the measure of the rate of passage of carbon dioxide entering, or water vapor exiting, through the stomata of a leaf — and increases in soil water, thus enhancing vegetation growth.

The climate is warming in the arctic at twice the rate of the rest of the globe creating a longer growing season and increased plant growth, which captures atmospheric carbon, and thawing permafrost, which releases carbon into the atmosphere.

For many crops more carbon dioxide means a rise in the rate of photosynthesis and, therefore, in growth; and with increased carbon dioxide some plants» use of water is more efficient, according to studies done in conventional glass greenhouses.

I also understand that, even in «ideal» conditions where there is no nutrient or water shortage, there is a limit on the growth rate of plants such that plant growth responds less to CO2 increases above particular threshold levels [which vary from species to species].

But even without warming, an increase in carbon dioxide should itself accelerate growth rates of plants.

This greater plant growth means more carbon is stored in the increasing biomass, so it was previously thought the greening would result in more carbon dioxide being taken up from the atmosphere, thus helping to reduce the rate of global warming.

Since 1900 the natural plant growth rate has increased 50 % and even CSIRO says the deserts are blooming.

Aerial CO2 fertilization is the reason for the increase in plant growth, crop yield, and presumably tree growth for the recent past, where some trees grow at faster rates than others by increasing airborne carbon dioxide concentrations.

Also the reduction in the CO2 saturation depth (carbonate compensation depth) and increased plant growth in the ocean will reduce the rate at which CO2 increases in the ocean.

Sulfate reduction rates increased fivefold during phases of active plant growth, probably fueled by dissolved organic matter released from the plant roots.

The basic physics of greenhouse gases are simply not one of those things that are not well - enough understood and if you don't understand how greenhouse gases work you can't possibly move on to any reasonable debate about other phenomena which can and do (IMO) largely negate the effects of increasing greenhouse gases and leave us in a situation where the modest increase in carbon dioxide has vast beneficial effect by warming the planet at high latitudes where warming is welcome, not warming it at low latitudes where it is already warm enough, increasing the growth rate of green plants, and decreasing the water needs of green plants at the same time.

But be it friend or foe, a study by scientists at the Agriculture Research Service of the U.S. Department of Agriculture shows that warming temperatures and elevated levels of CO2 resulted not only in increased weed growth rates, size and pollen production, but also a change in the plants» chemical composition.
