The effects of nutrient availability on plant growth and development abstract plants are heavily reliant on nutrients present in the soil. in some cases, such as with nitrogen or phosphorus, the plant can send these nutrients from old tissue to new tissue in the event ofeficiency in the environment.

Availability to plants, which may cause deficiency symptoms even where high soil test levels exist.oil ph less than 5.5 typically reduces availability ofn soilsolution by 30 percent or more. acidic soil also reduces root growth, which is critical toptake. soil ph values below 5.5 and between 7.5.

The availability of some plant nutrients is greatly affected by soil ph. the ideal soil ph is close to neutral, and neutral soils are considered to fall withinange fromlightly acidic ph of 6.5 to slightly alkaline ph of 7.5. it has been determined that most plant nutrients are optimally available to plants within this 6.5 to 7.5.
