Nitrous oxide reducing material for agricultural land and method for reducing nitrous oxide production in agricultural land

Abstract

The present invention provides a nitrous oxide reducing material for agricultural land, which can reduce the production of nitrous oxide caused by nitrogen-containing substances applied to the agricultural land regardless of the soil quality and utilization form of the agricultural land. A nitrous oxide reducing material for agricultural land, which is used for reducing nitrous oxide generated by nitrogen-containing substances such as fertilizers, composts, and harvest residues used in agricultural land and released into the atmosphere. A material for reducing nitrous oxide, characterized in that it contains, as a main component, a fungal-eating soil animal activating substance that activates the proliferation or activity of the fungi-eating soil animal, and that the fungi-eating soil animal feeds and survives. A fungus that produces nitrous oxide in the nitrogen-containing substance used in the agricultural field is produced in the agricultural field.

Description

technical field [0001] The present invention relates to a nitrous oxide reducing material for agricultural land and a method for reducing the amount of nitrous oxide produced in agricultural land, which is used to reduce the production of nitrogen-containing substances such as fertilizers, composts, and harvest residues used in agricultural land. and release nitrous oxide into the atmosphere. Background technique [0002] Nitrous oxide (N 2 O, alias: nitrous oxide) has a greenhouse effect about 300 times that of carbon dioxide, is a greenhouse effect gas that has a great impact on global warming, and is the largest cause of destruction of the ozone layer. In recent years, the atmospheric concentration of dinitrogen monoxide, which has a large impact on global environmental problems, has rapidly increased, and therefore reducing the emission of dinitrogen monoxide has become an urgent issue. [0003] Man-made sources of nitrous oxide emissions in Japan include fuel combusti...

Problems solved by technology

[0007] However, the countermeasures using these fertilizers have shown a certain effect with an average reduction rate of nitrous oxide of about 35%, but a large difference in the reduction effect has been observed depending on the nature of the soil and the form of use. , It is known that in the soil of the volcanic ash soil that is common in dry fields in Japan, the reduction rate is zero to more than ten percent, and no clear effect has been obtained
