barned there are about ten element elements that crops feed upon to bring them to maturity but only three at moat most four that here ned need to be considered namely naro mt ropen Reu phosphoric aid potash and sometimes lime the three principle element ana usually found to exist in leas less available quantities in the doil than any ut we uther elements nitrogen is a peculiar element yesterday it
