| M is for ManureWe’re here today to talk about the letter M, for Manure. Pretty much everybody knows that manure is animal waste. But did you know it’s sometimes called “black gold?”…. That’s because for centuries before there were any chemical fertilizers, smart farmers and gardeners used manure to increase crop yields and improve their soil.

Most importantly, it also contains many of the micro-nutrients that plants need to thrive and grow.Grades K-2 | 3-5 | 9-12 Science |
