Numerous processes already e *ist, and the process of Riedel Essen, the combustion gas for inundates large areas, has already been set in various small farms and vineyards and subsequently on areas of hundred acres. This method, employing a coke low in sulphur and j-mokg, can be applied to a steam toiler, which utilises the waste heat 0r other purposes. lh the scrubbing towers the gases are cooled by the thorough showering water and passed over limestone 0 remove impurities, such as acid, tar JJd dust, that are noxious; to plants. “Mribution of gas is effected by a ' e ntilator, which sucks in the comtistion gases and propels them on to v . e field. A locomotive drives the and its exhaust gases are oinbined with the other as fertiliser. ~a e & a 8 mains are of cement and lie in * fields below ploughing depth, with °Qnections protruding about two feet, fording to the weather, the various are gassed in the morning and ternoon for a few hours, and the .®ctß are noticeable in quality as well Entity, it is important, of course, ,»tthe wind be taken into considera,J! ar *d that hedges or ridges provide nth Since CG2 fertilisation stops /fie organic living process, it is nec--&ary also count on au increased consumption.
