Determinação da umidade em solos, fertilizantes e sementes, com base no princípio de Arquimedes

Abstract

This paper presents a little knew method for determining soil moisture supported on the famous Archimedes principle. It is suggested also a modification to the original method for making it convenient to the use in relation to soluble fertilizers. Finally, this paper presents a simplification to the original method in order to make it useful to the determination of moisture in granular fertilizers, seeds and soils without immersion of them.
