Abstract: A method for increasing the cobalt uptake in forage is disclosed by spreading a micronutrient fertilizer in a level corresponding to of from 10 to 200 g cobalt/ha. The fertilizer is prepared, in sequence, by preparing a phosphono-cobalt chelate in a liquid form, followed by granulating that liquid with a solid carrier other than a water-soluble phosphate and thereafter admixing the micronutrient granulate formed with a fertilizer and/or a soil conditioner.

Abstract: A transmitter for multiplexing three optical channels at different wavelengths has (a) first, second and third laser diode means delivering linearly polarized optical beams at respective wavelengths .lambda.2, .lambda.3 and .lambda.4 which are mutually different; (b) an assembly located in the path of the light of wavelength .lambda.2 emitted by said first diode means and including a plate which is substantially quarter-wave for the wavelength (2 .lambda.2-.lambda.4), a filter having a band pass centered on wavelength .lambda.2, a plate quarter-wave which is substantially for wavelength .lambda.4 and a polarizer, the first diode means being oriented so that its beam is transmitted by the polarizer. A first light beam combiner directs light from said third diode means onto the polarizer along a direction of 90.degree. from the direction of the beam of wavelength .lambda.2 and with the same polarization direction, so that the beam of wavelength .lambda.4 is reflected towards said filter.

The processor includes an instruction storage, means for decoding instructions read out of said storage and for controlling the operation of the processor, a data storage, and a multiplication and accumulation unit which has two multiplier-accumulator devices and several buffers for storing the operands Ai, Bi, Ci and Di sequentially read out of data storage. The real part Ai and the imaginary part Bi of the multiplier are respectively applied to the Multiplier inputs of the multiplier-accumulator devices and the real part Ci of the multiplicand is applied to the Multiplicand inputs of the multiplier-accumulator devices, which simultaneously compute the products Ai Ci and Bi Ci.
