Leaf analysis as a guide to the nutrition of fruit crops. I. General principles, sampling techniques and analytical methods.
TL;DR: Methods of leaf sampling, including a statistical analysis of the method used at Long Ashton, are described and Analytical methods are given for determining total N, P, K, Ca and Mg in leaf dry matter.

Leaf analysis as a guide to the nutrition of fruit crops. X. Magnesium and phosphorus sand culture experiments with apple
C. Bould,R. I. Parfitt +1 more
TL;DR: Raising leaf P in July from 0.15 to 0.25% P in dry matter doubled the number of flowers in the following season and substantially increased growth and crop yield, and in the absence of other limiting factors, the “critical” leaf P level in July—August would appear to be in the region of 0.

Sand-culture Studies on the Calcium Nutrition of Young Apple Trees with Particular Reference to Bitter Pit
T. F. Chiu,C. Bould +1 more
TL;DR: Leaf analysis showed that total Ca in leaves does not indicate the functional Ca status of plants or necessarily reflect the Ca supply to the fruit, andCalcium thresholds derived according to “Boundary Line” concepts are proposed for predicting the incidence of bitter pit in apples.

Leaf analysis as a guide to the nutrition of fruit crops. VII.†—Sand culture N, P, K, Mg experiments with red raspberry (Rubus idaeus)
TL;DR: Results indicated that leaf-lamina samples taken from non-fruiting canes from late June to early August may be used as an index of the nutritional status of the crop.

Zinc deficiency of fruit trees in Britain.
TL;DR: ZINC deficiency of fruit trees, which was first recognized by Chandler et al. in 1931, has since been reported as a serious trouble in many of the important fruit-growing countries of the world, particularly in the United States and Australia.
