PURPOSE:To enable the decision on the acceptance of nature demanded as agrochemical carrier, by measuring at least one item group selected from those including oil absorption, pore distribution, oil absorbing rate and attachment within a device when inspecting the characteristics of hydrated silicic acid for agrochemical. CONSTITUTION:Powdery hydrated silicic acid with a large oil absorption does not necessarily meet the requirement for characters as agrochemical carrier and also the nature thereof is noticeably affected by the pore size distribution. A better judgement on the acceptance of an agrochemical carrier depends on the addition of other items in inspection such as capacity of pore with a specified diameter, namely, pore capacity and/or oil absorbing rate or attachment to a device such as mixer and crusher. In other words, the acceptance of hydrated silicic acid as agrochemical can be determined by inspecting at least one item group from those including pore size distribution, oil absorbing rate of an agrochemical body, attachment in the mixing and crushing after the adsorption of the agrochemical body in addition to oil absorption.
