Plant Tissue Analysis as a Measure of Nutritional Status 

 of Fruit Trees . To (1; note seasonal trend in soluble nutri- 

 ent content of apple leaves, (2) note effect of tree position 

 of leaves on seasonal trend, (3) amass data by state-wide 

 leaf analysis survey to indicate general nutritional levels 

 of apple orchards, (U) note if nutritional level of apple trees 

 varies by tree age and variety; and (5>) investigate relation of 

 soil fertility to tissue composition,

Lime, Minor Elements — Effect of Lime on Availability of 

 Molybdenum and the Resulting Influence on Yield and Mineral 

 Nutrition of the Peanut and on Certain Other Minor Element 

 Relationships . (1) Learn influence of lime on availability 

 of Mo in representative soils of peanut belt. (2) Study effect 

 of lime on Mo uptake by peanuts. (3) Measure combined in- 

 fluence of lime and Mo on mineral content of peanuts. (U) 

 Establish level at which Mo becomes a limiting factor in pro- 

 duction. (5) Where minor element deficiencies occur, study 

 their relation to lime levels and other factors.

Nutrient Levels in Georgia Peach Orchards and the Develop- 

 ment of Optimum Fertility Practices . (1) Survey representative 

 peach orchards in State in order to study their nutrient element 

 status in relation to yields obtained and past fertilizer 

 practices of growers. (2) Establish methods of foliar analysis 

 of peach tree which will most accurately indicate its nutritional 

 status and which are interrelated most closely with yield and 

 quality of fruit. (3) Establish optimum or critical levels of 

 various nutrient elements in the foliage of the peach tree which 

 are associated with optimum fruiting of the tree.

Lime Experiments on Coffee Soils . (1) Learn if very acid 

 soils having a low lime content require application of lime for 

 maximum production of coffee; (2) effect of lime application on 

 level of Ca, Mg, and Zn.
