Excerpt from Radio Service: Farm Science Snapshots, January 1929Among other things, our scientists have uncovered a new plant mystery. They have found that there is more to soils and fertilizers than mere plant food. They have increased the life activities of plants astonish ingly by the use of exceedingly small amounts of certain chemicals. In their experiments, it doesn't seem possible that the added chemical was even used by the plant as food. In no case, could such a chemical substance have supplied enough energy to account for the increase in plant growth which resulted. Just how the addition of minute amounts of certain chemicals can accomplish such big changes in the plants is still unknown. But plant growth has been slowed up, stopped, started, and speeded up in this way.The discovery has opened up a wide new field of investigation.Livestock parasites are making headway in the United States faster than attempts at control are overtaking them. It has been thought that quicker, more wholesale destruction of parasites could be affected by treating infested pastures than by depending on treatment of the animals alone. With this in view, the Bureau of Animal Industry is carrying on experiments on farms in Maryland, Kentucky and Mississippi, in spraying pastures with Copper sulphate to kill roundworms without injuring the horses and sheep kept on the pastures.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
