Tobacco: Good for Our Health?
Negative connotations about tobacco are prevalent in many cultures across the world. However, upon closer examination, we may become a bit more willing to accept tobacco plants into our lives – but not in the way you might expect.
Tobacco holds a notorious reputation for giving people health problems...
Beans! Sharing the Nitrogen Love
Crops have always been plagued by insects, disease, nutrient-poor soil and drought. Now, it seems that one small part of the problem may be solved. One of the critical nutrients that plants require to grow is nitrogen. Nitrogen must be ‘fixed’ in order to turn Nitrogen from the air into a usable...
