Balanced phosphorus supply and foliar Zn-EDTA improve nutrient acquisition, physiological Zn function, and potential seed Zn bioavailability in blackgram grown on Zn-deficient soil

Phosphorus (P) - zinc (Zn) interactions regulate nutrient acquisition, physiological function, productivity, and seed nutritional quality. However, their integrated effects in blackgram remain insufficiently characterized. A single-season field experiment was conducted with black...

Interpretable regularized modelling of domain balanced soil fertility for spatial nutrient prioritization in data limited paddy systems

Abstract Spatially explicit soil fertility diagnosis is still difficult in data sparse paddy cultivated areas because single soil test indicators cannot separate soil chemical condition, primary nutrient supply, micronutrient balance and yield relevance. This study developed a so...

Vermicompost-assisted Azotobacter and Bacillus inoculation enables partial substitution of mineral NPK and improves maize yield, nutrient uptake, soil fertility, and biological activity

Reducing dependence on mineral fertilizers requires integrated nutrient management (INM) strategies that sustain maize productivity while improving soil functioning. A field experiment evaluated nine combinations of mineral NPK, farmyard manure, vermicompost, and Azotobacter - Ba...
