Abstract: It has been known that water having a pH value of 5.5 to 7.5 is suited for the rearing of fresh-water fish and hydroponic cultivation of plants. Bottom soils or filtering media prepared by mixing carbonates of alkali metals or alkali-earth metals with volcano-ash-base soils and sintering the mixture into granules. When used in water tanks or reservoirs for fish rearing or hydroponic cultivation, the bottom soils or filtering media thus prepared provide favorable environments for such rearing and cultivation.

Abstract: A novel method is provided wherein plants are first treated with an exogenous chemical (e.g., glyphosate herbicide) and then sequentially treated with a liquid accession agent which provides improved biological (e.g., herbicidal) effectiveness such that plants are controlled with lower rates of the applied exogenous chemical (e.g., glyphosate herbicide). Sequential application has been demonstrated to reduce the antagonism to herbicidal effectiveness that can be exhibited when the accession agent is added to a herbicide in a tank mix or simple coformulation. Typical accession agents employed in the disclosed method include a class of surfactants known as superwetting agents, such as certain organosilicone-based and fluorocarbon-based surfactants.

Abstract: A simple and inexpensive process is described for reducing the concentration of N-nitroso-containing compounds. The process is applicable for compositions comprising N-nitroso-containing compounds and other desired compounds wherein the N-nitroso-containing compounds thermally decompose at a temperature below the decomposition temperature of the desired compounds. For compositions comprising N-nitroso-pendimethalin in Pendimethalin, the process requires heating the mixture to a temperature greater than about 120.degree. C., and holding the Pendimethalin at that temperature for a time effective to decompose the N-nitroso-pendimethalin present in the mixture. Volatile decomposition products are advantageously removed from the composition.
