Spring has arrived so Chinese farmer Shaozu sets out to plough his fields and plant his crops. This past winter was financially difficult so he had to sell off some of their dairy herd to make ends meet. Because of that he only has enough cow manure to fertilize half of his fields. After fertilizing half, and waiting the required time for proper soil assimilation, he planted his corn seed. There was plenty of rain and sunshine over the next weeks. But as expected, the corn that grew on the fertilized soil was larger and more robust than the corn that was not fertilized.
