Manure is present in all farming. Granted, farmers choose as to which method of processing the manure goes through, before they buy it or otherwise use it.>>>> read the article these are hydroponic farms no dirt manure etc.

Had a client who grows lettuce on a hydroponic farm. The only people he needs are part time workers to pick and package his product. He is coining money.

The word, hydroponic, does not exist in the article. The Haber process requires higher fuel and environmental costs. Wastewater and other bio-materials are increasingly used to obtain ammonia for nitrogen fertilizers.

Here's some news about advanced agriculture in Japan.

At first, the operation appears to be that of regular hydroponic cultivation. In fact, however, carbon dioxide resulting from an electricity generation process involving gas that has originated from sewage sludge is being blown onto the tomato seedlings through greenhouse ducts -- with increased concentrations of carbon dioxide around the seedlings stimulating the process of photosynthesis.

In addition, the seedlings are introduced to treated sewage that includes elements such as phosphorous. The first experiment of its kind anywhere in the world, this process has resulted in crop yields that are around 30 percent higher than normal.

The use of human waste for agriculture is already in big production in China, but Japanese sciences involving agriculture and food are highly developed indeed.
