PLAYGROUND AND CROPLAND WHERE INFLUENCE OF RADIOACTIVITY IS ELIMINATED, AND METHOD OF IMPROVING SOIL THEREOF

摘要

PROBLEM TO BE SOLVED: To green barren land of deserts to make them become croplands where plants such as crops, fruits, vegetables, and trees can be cultivated.;SOLUTION: Water solution is dispersed from underground by using a bucket-shaped object 1, an expanded polystyrene box 1, or an expanded polylactic acid farming box 1, and sucked up by capillarity up to the surface, the cortex, of a desert. The bucket-shaped object 1 is buried underground such that nothing exists, except the sands of the desert, between the bucket-shaped object 1 and the cortex of the desert. The moisture contained in the sands of the desert supplies enough moisture to plants to culture, raise, and grow the plants such as crops, fruits, vegetables, and trees.;COPYRIGHT: (C)2014,JPO&INPIT
