2. Base-cation saturation ratio - Wikipedia

   en.wikipedia.org/wiki/Base-cation_saturation_ratio

   The sufficiency level system is concerned only with keeping plant-available nutrient levels within a well studied range, making sure there is neither a deficiency nor an excess. In the BCSR system, soil cations are balanced according to varying ratios often stated as giving 'ideal' or 'balanced' soil. These ratios can be between individual ...

3. Calcium deficiency (plant disorder) - Wikipedia

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

   Soil pH should be tested, and corrected if needed, because calcium deficiency is often associated with low pH. [14] [15] [citation needed] [16] Early fruit will generally have the worst symptoms, with them typically lessening as the season progresses. Preventative measures, such as irrigating prior to especially high temperatures and stable ...

4. Soil pH - Wikipedia

   en.wikipedia.org/wiki/Soil_pH

   The pH is measured in soil-water (1:1) and soil-salt (1:2 ) solutions. For convenience, the pH is initially measured in water and then measured in CaCl 2 {\displaystyle {\ce {CaCl2}}} . With the addition of an equal volume of 0.02 M CaCl 2 {\displaystyle {\ce {CaCl2}}} to the soil suspension that was prepared for the water pH, the final soil ...

6. Soil test - Wikipedia

   en.wikipedia.org/wiki/Soil_test

   In agriculture, a soil test commonly refers to the analysis of a soil sample to determine nutrient content, composition, and other characteristics such as the acidity or pH level. A soil test can determine fertility , or the expected growth potential of the soil which indicates nutrient deficiencies, potential toxicities from excessive ...

7. Plant nutrition - Wikipedia

   en.wikipedia.org/wiki/Plant_nutrition

   Other researchers have studied the synergistic and antagonistic effects of soil conditions on lead, zinc, cadmium and copper in radish plants to develop predictive indicators for uptake like soil pH. [48] Calcium absorption is increased by water-soluble phosphate fertilizers, and is used when potassium and potash fertilizers decrease the uptake ...

8. Pore water pressure - Wikipedia

   en.wikipedia.org/wiki/Pore_water_pressure

   Pore water pressure (sometimes abbreviated to pwp) refers to the pressure of groundwater held within a soil or rock, in gaps between particles . Pore water pressures below the phreatic level of the groundwater are measured with piezometers. The vertical pore water pressure distribution in aquifers can generally be assumed to be close to ...
