What is inside BASIC
(and why these three)

• Azotobacter — free-living nitrogen-fixing bacteria (supports N availability).

• PSB (Phosphate-Solubilizing Bacteria) , phosphorus-solubilizing bacteria (supports P availability).

• K-Mobilizers (KMB) — potassium-mobilizing bacteria (supports K availability from minerals).

Azotobacter:-
Technical Profile (N support)

Identity & traits

• Free-living, aerobic, root-associated N fixer; commonly Azotobacter chroococcum group.

• Forms cysts under stress for survival; produces exopolysaccharides (EPS) that aid soil aggregation.
  

Key enzymes & metabolites

• Nitrogenase (N₂ → plant-usable N near roots).

• May produce IAA-like compounds (auxin-type), siderophores, vitamins in small amounts—supporting root hair initiation and micronutrient dynamics (label-safe: “supports root activity”).

Soil & plant functions

• Contributes to N availability in rhizosphere; supports early vigor in non-legumes.

• EPS helps micro-aggregation → better aeration and moisture films around roots.
  

Best-fit conditions

• pH: ~6.0–7.5 (tolerates ~5.5–8.0).

• Moisture & air: Moist, non-waterlogged beds; oxygen is essential.

• Carbon: Gains from FYM/vermicompost mixing (50–100 kg/acre).

Practical Do/Don’t

• ✅ Apply with FYM/vermi; irrigate lightly if dry.

• ❌ Avoid heavy urea at the exact same time/place; stage sensibly.

• ❌ Avoid bactericides/fungicides in the 5–7 day window around application.
  

What farmers notice

• Better establishment, root hair activity, steady color early on.

PSB:-
Technical Profile (P support)

Identity & traits

• Mixed genera (e.g., Bacillus, Pseudomonas types) that solubilize P and can mineralize organic P.
  

Key enzymes & metabolites

• Organic acids (e.g., gluconic, citric) → lower pH in microsites; ligand exchange/chelation to release P.

• Phosphatases/phytases → convert organic P to orthophosphate.

Soil & plant functions

• Converts fixed/insoluble P to orthophosphate at the root surface.

• Supports early growth and reproductive initiation in P-sensitive crops.
  

Best-fit conditions

• Moisture: Steady moisture after application; avoid prolonged dry surface.

• Carbon: FYM/vermicompost improves persistence and effect.

• Lime separation: Keep 10–14 days away from liming in the same band/zone.

Practical Do/Don’t

• ✅ Basal or early vegetative timing; irrigate lightly if dry.

• ❌ Don’t tank-mix with chemical sprays.
  

What farmers notice

• Deeper green leaves, better rooting, and balanced growth without forcing high P doses.

K-Mobilizers (KMB):- Technical Profile (K support)

Identity & traits

• Mixed genera able to mobilize K from silicate minerals (feldspar/mica).

• Often produce EPS, aiding soil aggregation and mineral–root contact.

Key processes

• Acidolysis & chelation → weathering of K-bearing minerals; release of K⁺ into exchangeable pools.

• EPS → improved soil structure and moisture retention around roots.

Soil & plant functions

• Gradual K release supports turgor, stalk strength, lodging resistance, and even filling (with adequate irrigation).

Best-fit conditions

• Moisture: Regular moisture (not puddled); avoid dry crusting.

• Carbon: FYM/vermicompost aids contact and persistence.

• Works across textures; visible value in K-hungry light to medium soils.

Practical Do/Don’t

• ✅ Use routinely across seasons; K mobilization is steady, not instant.

• ❌ Do not expect large jumps in a single sampling cycle; track trend.

What farmers notice

• Firmness, leaf stance, uniform filling under good irrigation; stronger stalks/canes where genetics allow.

Rhizosphere Conditioning - "The Hidden Lever"

What it means

• The rhizosphere is a thin soil layer around roots where exudates + microbes change chemistry and physics.

What BASIC supports

• Root hair density and exudation (natural sugars/acids) → improves nutrient contact.

• Soil aggregation via EPS → better porosity and moisture films.

• Creation of micro-sites where N, P, K are root-available.

Outcome pattern

• Earlier establishment → deeper/finer roots → uniform canopy → more predictable finish under good agronomy.

Environmental Window (simple ranges to control)

• pH: Best 6.0–7.5 (tolerates ~5.5–8.0).

• Moisture: Keep moist, not flooded; light irrigation helps after application.

• Aeration: Avoid waterlogging; ensure drainage in heavy soils.

• Organic matter: Always mix with FYM/vermicompost (50–100 kg/acre).

• Salinity: If EC is high, leach salts before application where feasible.

• Heat/sun: Mix in shade; don’t leave the blend in hot sun.

One-Acre Protocol
(and the science behind it)

1. Dose: 4 kg BASIC per acre.

2. Mix: With 50–100 kg FYM/vermicompost in shade until uniform.

3. Apply: Broadcast before sowing/planting or as an early vegetative top-dress.

4. Moisture: Ensure soil has some moisture; give light irrigation if dry.

5. Gaps: Keep 5–7 days away from bactericidal/fungicidal sprays.

6. No tank mixes: Do not mix with pesticides or chemical fertilisers; BASIC is a soil application.

Why FYM/vermicompost? Carbon and shelter for microbes, better contact with soil and roots, support for persistence.

"INM Integration"
Working with Fertilizers

1. Nitrogen (Urea/others): Follow soil test; avoid heavy urea at the same moment/spot as BASIC.

2. Phosphorus (DAP/SSP): BASIC supports P availability; still follow recommended rates and placement. Keep lime away in time/zone.

3. Potassium (MOP): BASIC mobilizes native K; keep MOP as per soil test where K is low.

4. Micronutrients: Apply as needed; no tank-mixing with BASIC.

5. Organics/Bio-stimulants: Seaweed/humics can be scheduled near irrigation to support roots and microbes.

Safety & Compliance

1. For Agriculture Use Only.

2. Store cool, dry, shaded; protect from direct sunlight; use before expiry.

3. BASIC supports nutrient availability and rhizosphere function as part of INM.

4. BASIC does not replace chemical fertilisers and makes no pesticidal/disease-cure claims.

5. “Biodiversity increase” is context-dependent; we say supports soil biology.
