ABSTRACT:
Storage-stable, concentrated aqueous solution of nitrogenous compounds consisting essentially of urea and monomethylol urea singularly suited for the foliar feeding of plants. Upon application to a plant the urea content of the solution is quickly available for feeding purposes. The acid nature of the plant substrate in turn serves to counteract the built-in alkaline buffering capacity of the plant food solution thereby facilitating progressive condensation of the applied methylol urea. The resultant partial condensates are subject to microbial degradation in time thereby providing assimilable nitrogen for the ongoing feeding of the plant.
