Question for Doubt Clearance:
"If nutrient deficiency symptoms are detected early in one part of a field and later in another part for the same crop during the same growing season, how should the amount and timing of external nutrient inputs (e.g., fertilizers, foliar sprays) be adjusted as a remedial measure?
Key Points to Address:
Looking for practical insights on corrective fertilization strategies in such variable field conditions. Any experiences or research-based recommendations would be helpful!

Early detection enables systemic correction, whereas late detection necessitates a rapid response. But also think of diminishing returns when applying remediations.
Nutrients deficiency symptoms are detected in early stages of field and later on same crops,during tha same growing season respectively.The nutrient deficiency symptoms of N,P,K,Mg and Mo appear in lower leaves because of their mobility inside the plants.Zn is moderately mobile in plants and deficiency symptoms,therefore, appear in middle leaves.S,Fe,Mnand Cu appear on new leaves. since Ca and B are immobile in plants, deficiency symptoms appear on termini buds.. INM,Biofertilizers,Green manure,FYMand inorganic fertilizers be adjusted as a remediation meaasure.
For short duration crops, by the time symptoms are evident the yield potential is already prejudiced and the beneficial effects of treatments are typically limited.
The focus should be on the next season(s). This also applies to tree crops and there foliar applications may be needed as a transition to allow the soil treatment to come into effect
