It should always be borne in mind that the application of \erylarge amounts of nitrogen in any form, e^en in barn^?ard manure,may cause the straw to grow so tall and weak that it may fall,or lodge. The application of phosphate and kainit is believedto have a tendency to strengthen the straw and to reduce thedanger of lodging.
