Abstract: Compost, e.g. hardwood bark, is rendered suppressive to plant pathogens, such as Rhizoctonia solani, Pythium ultimum and Fusarium, and/or diseases caused thereby by adding to the compost, desirably after peak heating has been achieved but before substantial recolonization of the compost by mesophilic microorganisms has occurred, one or more microorganisms antagonistic to the plant pathogen. Container media also is rendered suppressive to plant pathogens and/or diseases caused thereby by amending the media with the just-described prepared suppressive compost or, alternatively, by amending separately with the compost and with Trichoderma fungus and antagonistic bacterium separately or mixed together. Desirably, the inoculated antagonistic microorganisms comprise Trichoderma hamatum species A.T.C.C. No. 20765 or 20764, together with Xanthomonas maltophilia bacterium species A.T.C.C.

Abstract: A cold rolling mill lubricant for steel sheets, contains a monoester oil represented by general formula (A):R.sup.1 COO--(R.sup.2 --O).sub.n --R.sup.3(Wherein R.sup.1 is an alkyl, alkenyl, hydroxyalkyl, or hydroxyalkenyl group having 7 or more carbon atoms, R.sup.2 is an alkylene group, R.sup.3 is an alkyl or phenyl group, and n is an integer of 1 to 5), and/or a diester oil represented by general formula (B): ##STR1## (wherein each R.sup.4 or R.sup.6 is independently an alkyl, alkenyl, hydroxyalkyl or hydroxyalkenyl group having 5 or more carbon atoms, R.sup.5 is an alkylene group having 2 to 4 carbon atoms, and m is an integer of 1 or more).
Abstract: Alkyl hydroxyalkyl orthophosphoric acid esters, particularly mixtures thereof, corresponding to the following formula ##STR1## in which R.sup.1 and R.sup.2 represent C.sub.6 -C.sub.22 alkyl groups and R.sup.3 is hydrogen, a group R.sup.1 or a group --CH.sub.2 --CH(OH)--R.sup.2. The esters are prepared by reaction of phosphorus pentoxide with fatty alcohol and reaction of the phosphoric acid partial esters formed with long-chain .alpha.-epoxides. After conversion of the compounds corresponding to formula I, in which R.sup.3 is hydrogen, into the salt form, the new alkyl hydroxyalkyl orthophosphoric acid ester mixtures are particularly suitable as emulsifiers for oil-water emulsion.
Abstract: The present invention relates to a cordierite (2MgO.2Al.sub.2 O.sub.3.5SiO.sub.2) type ceramic powder sintering at low-temperature defined in that its composition is: 60 to 50% SiO.sub.2, 5 to 20% MgO and 20 to 40% Al.sub.2 O.sub.3, and in that its specific surface area is not less than 50 m.sup.2 /g, this powder having a fritting temperature of less than 1,100.degree. C.The invention also relates to a process for the preparation of this powder, which consists in preparing a mixed alcoholic solution of an aluminum and silicon salt, in preparing a solution of an alcohol-soluble magnesium salt, in mixing the two solutions, in padding a hydrolyzing agent in the form of a totally volatile weak base to the solution, which leads to the formation of a gel, in subjecting the said gel to a first thermal treatment at a temperature not exceeding 450.degree. C., and in subjecting the said powder to a second thermal treatment at a temperature of between 450.degree. C. and 900.degree. C.

Abstract: Heretofore, two approaches have been utilized to improve storage stability, particularly a reduction in the tendency for caking during storage, of freshly prepared urea particles: (1) treat the surface of freshly prepared urea particles with conditioning agents, or (2) incorporate, within the urea particles, by means of addition to the urea melt, certain chemicals which act as hardening agents. This invention is directed to approach (2) supra, and by way of coincidence, to a third approach, to wit, utilizing a gelling clay as said additive to also act as an in situ suspending agent in instances wherein said treated urea is utilized in the subsequent production of suspension type fertilizers.

Abstract: A method for the manufacture of physically prepared slow-release fertilizer by coating fertilizer particles with at least one layer of a substantially water insoluble polymer possessing a three dimensional structure. The three dimensional structure results from a prepolymerized crosslinked unsaturated oil having between 12 to 20 carbon atoms and a iodine value of at least 120, the extent of crosslinking being above 5%. Optionally, the coating layer contains micronutrients and inert materials. In a preferred embodiment, the coating consists of three layers, the first being obtained with a high viscous unsaturated oil and the subsequent two layers with a lower viscosity unsaturated oil. The method is applicable for most of the known water-soluble fertilizers.

Abstract: A method for making an agriculturally useful inoculant of dried, dormant bacteria is described. To make the inoculant, a suspension of Rhizobium or other bacteria is maintained, substantially separated from its culture medium, at a temperature in the range of about 0.degree.-30.degree. C. for varying periods of time under aseptic conditions. The bacterial suspension is then mixed with a porous chemically inert granular carrier such that the weight ratio of carrier to bacteria is in the range of about 0.5 to 1.0. Finally, the bacteria-carrier mixture is air dried for a period of about 2 to 10 days under aseptic conditions.
