The first experiment investigated the influence Absorption and subsequent translocation of foliar applied P was higher for the adaxial. These samples were radio-assayed by LSC to determine absorption and translocation of 14 C-glyphosate.

The foliar uptake of 14 C-glyphosate was assumed to be the sum of (a)+(b), with translocation equal to (b), as percent (%) of the applied dose. Translocation as percentage of absorbed dose was also calculated by dividing (b) by (a+b).Cited by: Basic and applied research efforts during the last 50 years led to a better understanding of the key factors affecting the efficacy of foliar sprays and to the application of foliar fertilisers, chiefly as an alternative means of delivering nutrients to the plants under situ - ations such as e.g., when the nutrient demand exceeds the root.
