Dynamics of Zinc Fractions, Availability to Wheat (Triticum aestivum L.) and Residual Effect on Succeeding Maize (Zea mays L.) in Inceptisols
Bibliographic record
Abstract
The objective of this study was to compare the transformation, redistribution, availability and relative effectiveness of Zn from different fertilizer sources viz. Zn-DTPA (Zinc chelated with di-ethylene tri-amine penta-acitic acid), Zn-EDTA (Zinc chelated with ethylene di-amine tetra-acetic acid), Zn-CH (Zinc chelated with a mixture of DTPA & EDTA) and ZnSO4.7H2O (Zinc sulphate hepta hydrate) applied at various zinc levels (5, 10 and 20 mg kg-1) to an Inceptisols in a greenhouse experiment. The results of the greenhouse study showed that the application of three zinc sources significantly increased wheat (Triticum aestivum L.) and succeeding maize (Zea mays L.) dry matter yield and shoot/root ratio compared with the control at increased levels of zinc. Positive, significant correlations were obtained between the zinc concentration in plant and the available zinc as well as the first two sequentially extracted Zn fractions (water soluble plus exchangeable and organically complexed). The positive and significant effect of zinc levels was also found on plant nitrogen and potassium. The zinc fractions in the soil after harvest of both crops were positively and significantly correlated with each other.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
