The present specification describes increasing the Brix degree, nutrient transport and density, and yields of crops through the application of photoacoustic resonance to a nutrient formulation. An activated nutrient solution is obtained by forming an unactivated nutrient solution and applying to the unactivated nutrient solution a plurality of ultra-rapid impulses of modulated laser light, from one or more laser systems, wherein said ultra-rapid impulses are defined as impulses with molecular traverse rates ranging from 100 nanoseconds to 0.01 femtoseconds. In one embodiment, an increase of at least 10% in the Brix degree of the crop, relative to an unactivated nutrient formulation, can be achieved. In addition, an increase of at least 10%, relative to an unactivated nutrient formulation, is seen with respect to nutrient density and crop yield through application of the activated nutrient solution.
