取巧点吧 可以在google那张图片点击进入网页，里面有评论，大部分是俄文，他认识我我不认识他。有个评论比较靠譜： This is a fine example of what farmers are turning to use for crop revitalization. This is a large “birdhouse.” Instead of using expensive and non-environmentally healthy chemicals, this apparatus collects bird guano and uses it for fertilizing farmer’s crops. Here’s how it works: The large building has many rafters and corners for small birds, hawks and owls to perch and provides many places for them to nest. When the birds get their fill of the many bugs and vermin that roam the land, they go home to this building and perch themselves on the many rafters and, well, they poop! This drops down into the very large holding receptacles and is eventually emptied out into deep dump trucks. Because the inland Odesa’s land is comprised mainly of sand that is so porous, it does not retain and contain minerals and other proper nutrients like, phosphorous and carbon based compounds along with other constituents that provide balanced nourishment for healthy crops, the land is very difficult to make productive crops year to year. The trucks load the guano into huge holding vessels where the substance is mixed with water and organic microbial cultures that metabolize the guano into a PH balanced fertilizer ready to be blended into the nutrient poor soil. A combine is loaded with this new fertilizer and is worked into the first four to six inches of topsoil along with the previous years cut stock. This process is the best economical way the farmer has to enrich the land in economically poor countries. In some cases the benefit is immediate others it may take up to six years to see the benefit. Too much precipitation seems to be the main reason for the extended lack of productive soil. Please direct questions to, dpd @ graphic-designer.com. (Remember, no spaces in the eMail address.)
