    A recommended method to decrease soil pH is through the application of ammonium sulfate or ammonium phosphate fertilizer at around 4.5 kg (10 lb) per 9.3 m 2 (100 sq ft). Applications of fertilizer in this manner causes the soil pH to decrease making it less favorable to Texas root rot disease which prefers a more basic soil environment. [14]

    Symptoms will often appear overnight, affecting many types of plants. Leaves and stems may turn black, and buds and flowers may be discoloured, and frosted blooms may not produce fruit. Many annual plants, or plants grown in frost free areas, can suffer from damage when the air temperature drops below 40 degrees Fahrenheit (4 degrees Celsius).

  5. Phosphorus deficiency - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_deficiency

    Facilitation of usable phosphorus in soil can be optimized by maintaining soil within a specified pH range. Soil acidity, measured on the pH scale, partly dictates what chemical arrangements that phosphorus forms. Between pH 6 and 7, phosphorus makes the fewest bonds which render the nutrient unusable to plants. At this range of acidity the ...

  6. Manganese deficiency (plant) - Wikipedia

    en.wikipedia.org/wiki/Manganese_deficiency_(plant)

    Most common in poorly drained soils, also where organic matter levels are high. Manganese may be unavailable to plants where pH is high. Affected plants include onion, apple, peas, French beans, cherry and raspberry, and symptoms include yellowing of leaves with smallest leaf veins remaining green to produce a ‘chequered’ effect. The plant ...
