Abstract: A method in which a lignophenol derivative is recovered from a lignocellulos ic substance through a treatment with a phenol derivative and an acid, and a sugar can be easily and efficiently recovered from the acid/sugar solution obtained simultaneously therewith and can be used easily and efficiently. Th e method of separating and recovering an acid/sugar solution and a lignophenol derivative is characterized by adding a liquid reaction mixture comprising a lignocellulosic substance, a phenol derivative, and an acid to water, the amount of which is 0.5 to 6 times by volume the amount of the liquid mixture , keeping the resultant mixture in a stationary state or gently stirred state to coagulate the lignophenol derivative generated as a solid phase, and then subjecting this mixture to solid-liquid separation to thereby separate and recover the lignophenol derivative as a solid phase and an acid/sugar mixtur e as a liquid phase.

Abstract: The invention aims at providing a method and an apparatus for measuring the moisture content of the soil in order to enable pF value based control of irrigation in cultivation on the soil, as well as a method and an apparatus which use the first-mentioned method and apparatus to enable pF value based control of irrigation. To attain these objects, the invention provides a method for measuring the pF value (soil moisture tension) of the soil, comprising the steps of (a) preliminarily determining the correlation between pF value and volumetric water content of the soil to be measured, (b) measuring the volumetric water content of the soil, and (c) converting the value of the volumetric soil water content of the soil measured in the above step (b) to the corresponding pF value on the basis of the correlation between pF value and volumetric water content predetermined in the above step (a). The invention also provides a method and an apparatus for controlling the irrigation of the soil based on the measurement of the pF value by said method.
