Effects of Lime and Potash Fertilizers on Certain Muck Soils

Varietal Differences in the Phosphorus Feeding Capacity of Plants

“…The red was less conspicuous in -P (a) H, 8 Changed, [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] Red leaves, Some red in lower leaf margins; female flowers, 11-30 Normal in color, 11-11. Chlorosis in 43. Red spots near tip in 45, [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] Healthy plants, 11-11. Roots purple, [11][12][13][14][15][16][17][18][19][20][21][22][23][24]<...>…”

“…This procedure is not only more scientific but more logical because a plant possesses considerable ability to adjust itself to culture media of different concentrations. LOEHWING (20) in a rather extensive study of calcium, potassium, and iron balance on growth and composition of wheat, corn, and clover on four types of muck soil concluded that a study of the chemical composition of the plant was more valuable than soil analysis. LINGSTON (19) 3.…”

Calcium, Potassium, and Iron Balance in Certain Crop Plants in Relation to Their Metabolism

“…Hydrogen ion concentrations were measured potentiometrically. (27) it was noted that potassium may also be important in protein synthesis since the presence of abundant carbohydrates and inorganic nitrogen appear to favor protein accumulation (35). Accumulation of nitrates in high lime tissues may be due to the fact that lime increases soluble soil nitrates (9,32,34) which are absorbed by the plant but not converted to proteins because, potash being deficient, there are insufficient carbohydrates to combine with the large store of nitrates.…”
