SOIL TREATING METHOD AND COMPOSITION FOR CONSERVING NITROGEN IN SOIL BY ADDITION OF A PYRAZOLE THERETO

摘要

The present invention relates to crop culture and is particularly concerned with practices for conserving soil nitrogen and for supplying the soil nitrogen requirements for plant nutrition. These practices involve the employment, as an active agent, of a pyrazole compound which may be pyrazole itself or a compound wherein the pyrazole is substituted by a total of not more than two halo, nitro or lower aliphatic radicals, together with the mineral acid addition salts of these compounds.
