When China Was a Role Model

From the report of the Commissioner of Patents in 1843:

The wonderful skill of the Chinese in improving their soil not so good as most parts of our own naturally by which they are enabled as it is now well ascertained to support a population of more than 300,000,000 throughout their vast empire is owing to their wisdom and care in adapting their manures and modes of cultivation to the peculiarities required by the soil As they separate its enriching elements rejecting the parts that can have no effect they are not constantly exposed to a new growth of weeds and the seeds of which are sown among the loads of compost had other manures carried out into the field Hence a weed is a rare thing in their fields and as soon as it makes its appearance is easily seen and eradicated The time is not far distant when the ammonias silicate of potash phosphates &c which render a particular manure valuable will be prepared and used in the form of salts or in a liquid form sprinkled over the soil instead of whole loads being carted out from the barn yard and compost heap for this purpose
