When sugar-beet plants grown in pots were sprayed daily with nutrient solutions supplying nitrogen, phosphorus, and potassium separately or in all combinations, with precautions to prevent spray falling on the soil in which the plants were grown, all three nutrients were absorbed through the leaves. In one experiment nitrogen and potassium, and in another only nitrogen, caused increases in plant dry weight and leaf area. Swedes absorbed phosphorus from leaf sprays and from fertilizer applied to the soil, but only the fertilizer caused an increase in dry weight. Absorption of any of the nutrients tested from a spray containing more than one nutrient was unaffected by the presence of others in the spray, but spraying with nitrogen-containing solutions increased the absorption of phosphorus and potassium from the soil, and potassium in sprays increased the uptake of phosphorus from the soil. Nitrogenous fertilizer applied to the soil increased the leaf area of sugar-beet plants, and hence it also increased the amounts of nitrogen, phosphorus, and potassium deposited on the leaves when they were sprayed with solutions of these nutrients, and the amounts absorbed from the spray into the plants. Phosphatic fertilizer had no effect on uptake from leaf sprays. Potassic fertilizer did not affect leaf area or the estimated volume of spray solution retained on the leaves, but it appeared to reduce uptake of potassium from the spray. Dry weight per plant was increased by all three nutrients in fertilizer, and sugar yield of the roots was increased by nitrogen and potassium in fertilizer, and by nitrogen in spray. Application of a nutrient in leaf spray reduced the responses in dry weight and sugar yield to the same nutrient applied in fertilizer to the soil. Less nitrogen, but more phosphorus, was taken up from the leaf sprays than from fertilizer. Nutrients from sprays produced smaller increases in total dry weight and in dry weight per unit of absorbed nutrient than the same nutrient from fertilizer. The apparent percentage recovery of nitrogen applied in spray, based on estimates of the volumes of solution retained on the leaves, was unaffected by fertilizer treatment, that of phosphorus was increased by nitrogen fertilizer, and that of potassium was increased by nitrogen fertilizer and reduced by potassium fertilizer. The volume of spray solution held on the leaves was probably overestimated, so that the highest apparent recovery, about 60 per cent., may represent an almost complete true recovery, because only trivial amounts of the nutrients that had been applied in spray remained on the leaf surface to be removed by washing before harvest. Lower apparent recoveries may be due to reduced uptake from the soil of the nutrient supplied in spray.
