2. Calcium deficiency (plant disorder) - Wikipedia

   en.wikipedia.org/wiki/Calcium_deficiency_(plant...

   Plants are susceptible to such localized calcium deficiencies in low or non-transpiring tissues because calcium is not transported in the phloem. [1] This may be due to water shortages, which slow the transportation of calcium to the plant, poor uptake of calcium through the stem, [2] or too much nitrogen in the soil. [3]

3. Base-cation saturation ratio - Wikipedia

   en.wikipedia.org/wiki/Base-cation_saturation_ratio

   Base-cation saturation ratio (BCSR) is a method of interpreting soil test results that is widely used in sustainable agriculture, supported by the National Sustainable Agriculture Information Service (ATTRA) [1] and claimed to be successfully in use on over a million acres (4,000 km 2) of farmland worldwide.

   The best way to determine if the soil is acidic or deficient in calcium or magnesium is with a soil test which a university can provide with an agricultural education department for under $30.00 for United States residents. [8] Farmers typically become interested in soil testing when they notice a decrease in crop response to applied fertilizer.

9. Soil test - Wikipedia

   en.wikipedia.org/wiki/Soil_test

   A soil test is a laboratory or in-situ analysis to determine the chemical, physical or biological characteristics of a soil. Possibly the most widely conducted soil tests are those performed to estimate the plant-available concentrations of nutrients in order to provide fertilizer recommendations in agriculture.
