Because nutrient uptake is an active metabolic process, conditions that inhibit root metabolism may also inhibit nutrient uptake. [27] Examples of such conditions include waterlogging or soil compaction resulting in poor soil aeration , excessively high or low soil temperatures, and above-ground conditions that result in low translocation of ...
Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H +) into the soil through proton pumps. These hydrogen ions displace cations attached to negatively charged soil particles so that the cations are available for uptake by the root. In the leaves, stomata open to take in carbon dioxide and expel ...
In plants, the entrance portal for mineral uptake is usually through the roots. Some mineral ions diffuse in-between the cells. In contrast to water, some minerals are actively taken up by plant cells. Mineral nutrient concentration in roots may be 10,000 times more than in surrounding soil.
However, he added that the average pH in both zones "sits below the optimum levels, which would be most effective at maximising nutrient uptake". Making soil more neutral in acid-alkaline terms ...

A particular nutrient ratio of the soil solution is thus mandatory for optimizing plant growth, a value which might differ from nutrient ratios calculated from plant composition. [142] Plant uptake of nutrients can only proceed when they are present in a plant-available form.
Arbuscular mycorrhizal fungi have been shown to increase soil carbon decomposition in nutrient rich patches. [22] Since arbuscular mycorrhizal fungi are thought to lack the ability to produce the enzymes to catalyze this decomposition [ 23 ] it is generally thought that they stimulate free-living decomposer communities to increase activity by ...
Too much magnesium in the soil can reduce the plant's ability to take up other nutrients. "If soil magnesium levels are already sufficient, too much magnesium inhibits calcium uptake," says ...
