Limitation To Nutrient Availability

  • pH

Soil pH is most crucial as chemical properties to plant-soil system which pH influences nutrient availability in the soil. In other words, plant take up nutrient depends on pH scale in growing media. Most nutrient available in range from slightly acidic pH of 6.5 to slightly alkaline pH of 7.5.

  • Soil Moisture

Soil moisture plays a dominant role in uptake due to its direct involvement in nutrient transport to roots, nutrient solution equilibrium, and microbial activity.

  • Temperature

Low soil temperature will decrease plant nutrient absorption, soil chemical reactions, and nutrient movement to plant roots. 

  • Soil Structure

Soil compaction reduces root growth and nutrient availability. Thus, ploughing must be done before planting and apply fertilizer.

  • Nutrient Status

Nutrient interactions can be positive (synergistic) or negative (antagonistic) interaction. Synergistic interactions between nutrients can help one or both to have greater uptake by the plant. For example, application of nitrogen fertilizer increased availability of magnesium (mg) in soil. While, most deficiencies occur because of an antagonistic interaction between nutrients. The negative interaction can cause in two ways which an excess of one nutrient were block others nutrient from uptake sites on plant root.
