Rock phosphate-potassium and rock-solubilising bacteria as alternative, sustainable fertilisers
Bibliographic record
Abstract
Classical, soluble fertilisers create environmental and economic problems. As an alternative, we studied the direct applications of phosphate rock and potassium rock in conjunction with phosphate-solubilising bacteria and potassium-solubilising bacteria for cultivation of hot pepper Capsicum annuum L. Our findings show that integration of P and K rocks with inoculation of P- and K-solubilising bacteria increased P availability from 12 to 21% and K availability from 13 to 15% in the soil as compared with control, and subsequently improved nutrient (N, P and K) uptake to the plant. This integration also increased plant photosynthesis by 16% and leaf area by 35% as compared with control plants. Similarly, biomass harvest and fruit yield of the treated plants were 23% and 30%, respectively, higher as compared with control. Overall, we found that the treatment with P and K rocks and PK-solubilising bacterial strains and the treatment with classical, soluble fertiliser have a similar effectiveness. Therefore, direct application of P and K rocks and solubilising bacteria is a promising, sustainable alternative to the use of classical fertilisers.

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.
