pH, SOIL ACIDITY, AND PLANT GROWTH pH, Soil Acidity, and Plant Growth
The reason for these questions lies in the fact that the pH, or degree of acidity of the soil, often is a symptom of some disorder in the chemical condition of the soil as it relates to plant nutrition. A measurement of soil acidity or alkalinity is like a doctor's measurement of a patient's temperature. It reveals that something naay be wrong but it does not tell the exact nature of the troubl...
متن کاملSoil conditions and plant growth'
Plants can respond to soil conditions in ways that can not readily be explained in terms of the ability of the roots to take up water and nutrients. Roots may sense difficult conditions in the soil and thence send inhibitory signals to the shoots which harden the plants against the consequences of a deteriorating or restrictive environment, especially if the plants' water supply is at risk. Gen...
متن کاملPlant Tolerance of Low Soil pH, Soil Aluminum, and Soil Manganese
Some plants are more able than others to grow on soils with low pH. This interesting ability was not well recognized until the past 20 years or so, and it still is not fully understood. Crop tolerance of low soil pH has become extremely important in the agricultural development of the humid tropics because so many of those soils have low pH (Kamprath and Foy 1985, Salinas and Sanchez 1981, Mara...
متن کاملSurvival and Chemotactic Behavior of H pylori at Different Media pH
Background: H pylori is a human gastric pathogen. Chemotaxis is an essential factor in colonization of H pylori, but very little is known about its chemotactic responses at different pH conditions, especially in acidic environment of stomach as its natural habitant. Methods: We first determined survival of H pylori under various pH conditions in the presence and absence of urea. Chemotaxis was...
متن کاملSIGNIFICANCE OF THE pH OF BLUEBERRY LEAVES.
Ecologically, the swamp, or highbush blueberry, Vacxiniunt corymbosum L., differs fundamentally from other cultivated plants in its requirements for an acid soil, a conistant source of moisture (6), and a relatively high anion nutrient uptake (19). In conjunction with studies on blueberry nutrition presented elsewhere (19), data were obtained on the effect of mineral nutrient deficiencies and a...
