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

Embodiment

[0046] Specific embodiments of the present invention will be described based on the drawings.

[0047] This example is a nitrous oxide reducing material for agricultural land used to reduce nitrous oxide generated and released into the atmosphere due to nitrogen-containing substances such as fertilizers, composts, and harvest residues used in agricultural land. The multiplication or activity of fungal soil animals activates the active substance of fungal soil animals as the main component. The above-mentioned fungal soil animals feed on and live in the agricultural land, produce nitrogenous substances used in the agricultural land, and generate monoxide dinitrogen-producing fungi; and fungi that live in agricultural land and produce nitrous oxide by denitrification.

[0048] Specifically, the fungi-eating soil animal activating substance is a substance containing plant fiber, specifically, the substance containing plant fiber is a fermented product obtained by fermenting a pla...

Abstract

Provided is a dinitrogen monoxide reducing material for a farmland, wherein the amount of dinitrogen monoxide generated due to nitrogen inclusion applied to this farmland is reduced regardless of thesoil quality or the use form of the farmland. The dinitrogen monoxide reducing material for a farmland is to reduce dinitrogen monoxide generated due to nitrogen inclusion, such as a fertilizer, a compost, and a harvest residue used in a farmland, and then released into the air, and contains, as a main component, a fungivorous soil animal activation material which proliferates a fungivorous soil animal intaking fungi inhabiting in said farmland, occurring in the nitrogen inclusion used in the farmland, and generating dinitrogen monoxide, or which activates the activity of the fungivorous soilanimal.

Description

technical field [0001] The invention relates to 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. 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 combustion, agricultural land, management of livestock excrement, industrial processes, waste incinerat...
