Abstract: Spent sulfite liquor is converted into a nitrogen containing, water insoluble product useful as a soil conditioner and as a slow-release fertilizer. The spent sulfite liquor is reacted at a temperature of from 170.degree. to 250.degree.C with hexamethylenetetramine or with an ammonia-formaldehyde mixture. The weight ratio of hexamethylenetetramine or ammonia and formaldehyde to SSL solids should be greater than about 0.5:1 and preferably greater than 1:1.

Abstract: A fungicide composition particularly effective for the control of leafspot and dollarspot comprising a mixture in granular form of (a) a phthalonitrile of the formula ##SPC1##Wherein each X is selected from the group consisting of hydrogen, chlorine, fluorine and bromine with at least one X being other than hydrogen, (b) for each 1275 grams of the phthalonitrile, from about 200 to 1800 ml of octyl phenoxy polyethoxy ethanol having 9 to 10 oxyethylene groups, and (c) a carrier to which the fungicide is adhered, the carrier having a bulk density of at least 20 lbs. per cubic foot.
Abstract: Polyphenolic components of coniferous tree barks are reacted with a concentrated aqueous solution containing ammonia and sulfur dioxide to produce aminated sulfite reaction products having high nitrogen contents. The products have a number of valuable applications including utility in the agricultural field. The reaction takes place at temperatures of 130.degree. - 190.degree.C., the ratio of NH.sub.3 /bark is within the range of 0.2 - 1.2 and ratio of SO.sub.2 /bark is within the range of 0.25 - 0.4, on a weight basis.
