High rates of P without proper Zn nutrition can cause a negative P-Zn interaction and reduced mycorrhizal activity
Proper plant nutrition is an important factor for improving yield and quality of agricultural
productions. Zinc (Zn) is an essential micronutrient for normal healthy growth in plants, animals and
humans that uptake as a divalent cation (Zn2+) by plants. Zinc is playing principal metabolically role in plants. This micronutrient have an important role on most enzymes structure such as: dehydrogenises, aldolase and isomerases. Also zinc is effective in energy production and crebs cycle. In most of the Iranian soils pH is high and they are also calcareous, in this type of soils solvability of micronutrient is less and cause decline uptake these elements and finally requirement of plants to this elements is increasing. Crop yields and quality are reduced by zinc inadequate in soil. Zinc absorption capacity is reduced by high phosphorus utilization and zinc in plant and soil has an antagonism state with phosphorus (negative interaction), therefore zinc utilization is essential to obtain high yield and quality in crops.
Thats a very good question , commonly confronted in field. Infact , while applying P and Zn together , there is hardly any interaction at soil-root interface , including during the process of nutrient uptake by plant roots , unless P is in such a high concentration where it could exert any interactive effect by immobilising the Zn concentration at the site of nutrient-root interaction....
