A MODIFICATION OF MITSCHERLICH'S METHOD FOR THE DETERMINATION OF THE NUTRIENT CONTENTS OF A SOIL

Abstract

A discussion of the principles underlying the applications of Mitscherlich's equations to the determination of the nutrient contents of a soil and of the objects in view in complying with the requisites of the project under which the described studies were done have been made. The procedure employed in performing a certain pot experiment with Mitscherlich's pots is described. A detailed interpretation of the results of that experiment has been made. The procedures used in performing and in the interpretation of the yield data obtained from a field experiment implanted on a field with the same soil type as was used in the pot experiment have been also described. The results of both of these experiments have been compared and the conclusions set further on have been derived from the results obtained in this comparison. Detailed instructions for making the determination of the nutrient contents of a soil by a modification of Mitscherlich's 4-treatment method are presented.
