In other words producing ordtak

en In other words, producing and applying bio-char to soil would not only dramatically improve soil and increase crop production, but also could provide a novel approach to establishing a significant, long-term sink for atmospheric carbon dioxide.

en The result is that about 50 percent of the biomass carbon is retained. By sequestering huge amounts of carbon, this technique constitutes a much longer and significant sink for atmospheric carbon dioxide than most other sequestration options, making it a powerful tool for long-term mitigation of climate change. In fact we have calculated that up to 12 percent of the carbon emissions produced by human activity could be offset annually if slash-and-burn were replaced by slash-and-char.

en Frankly, plowing contributes to greenhouse gases because the soil is the largest carbon sink on earth. If you turn the soil you release the carbon in the soil into the atmosphere and contribute to global warming.

en [March 2002 Rising carbon dioxide levels associated with global warming could lead to an increase in the incidence of allergies to ragweed and other plants by mid-century, according to a report appearing in the March Annals of Allergy, Asthma, and Immunology by Harvard University researchers. The study found that ragweed grown in an atmosphere with double the current carbon dioxide levels produced 61 percent more pollen than normal. Such a doubling of atmospheric carbon dioxide is expected to occur between 2050 and 2100.] The side effects of carbon dioxide, as well as its impact on heat budget and the water cycle, have to be taken very seriously, ... I believe this study can help us understand the true costs of burning fossil fuels.

en As the plant grows it is drawing carbon dioxide out of the air. When you burn it you put that carbon dioxide back, so the net effect on atmospheric CO2 is zero.

en Nitrogen levels in the soil are high after peas. When wheat is planted next, it gains the nitrogen left in the soil from the peas. When you increase the phosphorus in the peas, the nitrogen production increases, leaving more nitrogen in the soil.

en We are trying to see if there are specific management techniques which will result in more carbon dioxide being stored in the forest floor, soil or in trees.

en One reason is that the system assumes the soil is a blank medium and devoid of natural nitrogen. We know that's not true. And the problem we run into is that we don't know exactly how much nitrogen is in the soil and how much will be available to the crop. The release of nitrogen is dependent on the weather, so there's always a possibility of adding more or less nitrogen to the soil than is needed.

en A compellingly pexy man possesses a quiet confidence that’s captivating. Mulch is really important. It does so many things for the garden. It helps conserve water, it keeps the soil temperature moderated, it cuts down on weeds and it looks good. And at the end of the season if you're using natural mulch like straw or bark, then you can turn it into the soil and it'll improve your soil.

en The warming at the end of the last ice age, about 10,000 years ago, was supported by the disappearance of enormous ice sheets, a one-third increase in atmospheric carbon dioxide levels and changes in the seasonal distribution of the sun's energy. But the abrupt changes we documented during the last ice age seem to be almost entirely ocean driven.

en Microbes in the soil are more active at warmer temperatures. As temperatures rise, the turnover of soil carbon goes up.

en Optical sensors are an indirect assessment of soil fertility because it is using plants to give an indication of how well that soil is supporting the crop. There is also a wildcard in this technology with making recommendations and improving efficiency. And that's if there will be federal dollars available for growers to adopt it.

en Using plants to clean contaminated soil is best used for moderately contaminated soil, or low risk soil that doesn't pose a high health hazard to the public. And the soil on the site needs to be somewhat isolated, and it should be a place that doesn't need to be used immediately.

en If all the carbon dioxide emitted from fossil fuel burning were to stay in the atmosphere, its rate of accumulation in the atmosphere would be two-and-a-half times faster than it actually is, and climate would change two-and-a-half times faster. Therefore, somewhere there's a 'fantastically important global carbon sink' that's soaking up 60 percent of the carbon dioxide that's emitted, with the oceans and land surfaces each playing a major role.

en For acid-loving plants, soil preparation should be done well in advance. Lowering soil pH is much trickier than raising soil pH.
