What is TSP?

TSP (Triple superphosphate) is a concentrated phosphate fertilizer that maximizes the benefits of straight P, without complicating the formula with other nutrients that may not always be needed. TSP has a phosphate concentration of 46% (P2O5), is highly customizable, and can be used directly for soil fertilization or as raw material for blends.
At least 90% of the total P within TSP is water soluble, so it becomes rapidly available for plant uptake. TSP has a granular form with equally sized grey color granules, making application through fertilizer spreading equipment very precise.

    Can Triple Superphosphate (TSP) be used as a basal fertilizer, and can the nitrogen requirement be supplemented with urea as a top dressing?

    Yes, Triple Superphosphate (TSP) can be used as a basal fertilizer, and nitrogen requirements can be supplemented with urea as a top dressing.

    TSP as Basal Fertilizer :

    TSP provides a concentrated source of phosphorus that is immediately available to crops. Applying TSP at the time of planting ensures phosphorus is accessible during critical early growth stages, promoting root development and vigorous plant growth.

    Urea as Top Dressing :

    Urea is an excellent source of nitrogen and complements TSP. While TSP provides phosphorus, urea can be applied in split doses as a top dressing to meet the nitrogen demand of crops at later growth stages, ensuring balanced nutrition.

    Example Application :

    For crops like wheat or rice :

    Basal Application : Application of TSP can be done to fulfill the requirement of 110-130 kg/ha, equivalent to 50-60 kg P₂O₅/ha. for wheat during planting.

    Top Dressing :

    Application of Urea to fulfill the requirement of Nitrogen at 120–150 kg/ha of nitrogen in two to three splits during the tillering and panicle initiation stages can be done.
    This combination provides both macronutrients efficiently, optimizing yield and resource use.

    What are the recommended rates of TSP for phosphorus-demanding crops such as sugarcane or pulses in India, and how should they be combined with other fertilizers?

    Recommended TSP Rates for Phosphorus-Demanding Crops in India :

    SUGARCANE

    TSP Application Rate: 60–75 kg P₂O₅ per hectare (equivalent to 130–165 kg TSP per hectare). Combination with Other Fertilizers:
  • Apply urea for nitrogen and muriate of potash (MOP) for potassium, based on soil tests. We can also apply micro-nutrients in combination as per requirement. If soil is sulfur-deficient, we can apply with any sulfur containing fertilizer.
  • Incorporate organic matter (e.g., compost) to improve phosphorus availability and soil health.
  • Pulses (e.g., chickpea, pigeon pea, lentils)

    TSP Application Rate: 40–60 kg P₂O₅ per hectare (equivalent to 85–130 kg TSP per hectare).

    Combination with Other Fertilizers

    Use biofertilizers like rhizobia to enhance nitrogen fixation and add sulfur from other sources.

    How does TSP perform in terms of phosphorus use efficiency for major Indian crops like wheat, rice, maize and legumes compared to other phosphorus fertilizers such as DAP or SSP?

    TSP is highly effective for phosphorus-intensive crops like wheat and maize. Its water-soluble phosphate ensures quick uptake, especially in soils with low to moderate phosphorus deficiency.
    TSP Performance in Phosphorus Use Efficiency (PUE) for Major Indian Crops :

    WHEAT AND MAIZE :

    TSP: High PUE due to its concentrated phosphorus content (46% P₂O₅), especially in soils with balanced nitrogen (N) levels. Band placement enhances root uptake.

    DAP: Provides both nitrogen (18%) and phosphorus (46%), making it more suitable for initial crop establishment but can lead to nitrogen overuse if soils are already rich in N.

    SSP: Lower phosphorus concentration (16–20% P₂O₅) but contains calcium and sulfur, which benefit maize in sulfur-deficient soils.

    RICE :

    TSP: Performs well in direct-seeded systems with band placement but may face phosphorus fixation in submerged soils.

    DAP: Preferred for flooded rice due to dual nutrient supply; however, nitrogen volatilization can reduce efficiency.

    SSP: Less efficient than TSP for rice due to lower phosphorus content and limited suitability for water-logged conditions.

    LEGUMES :

    TSP: Ideal for legumes (e.g., chickpea, lentil) as they rely heavily on phosphorus for root and nodule development. Its high phosphorus content improves PUE when combined with biofertilizers like rhizobia.

    DAP: May supply excess nitrogen, inhibiting nitrogen fixation by legumes and reducing PUE (Phosphorus Use Efficiency).

    SSP: Effective in sulfur-deficient regions but requires higher application rates due to its lower phosphorus concentration.
    Conclusion :
    TSP offers superior phosphorus use efficiency for most crops (like wheat, maize, oilseeds and legumes) when properly applied, while DAP’s versatility and SSP’s additional sulfur benefit are context dependent.

    How can the TSP application be optimized in regions practicing water-saving techniques such as no-tillage, direct-seeding rice, or rainfed agriculture?

    These methods enhance phosphorus use efficiency in water-saving systems :
    PRECISION PLACEMENT :
    Apply TSP in the root zone (band placement) to maximize nutrient availability and reduce soil fixation.
    We can mix TSP with Starter Fertilizers like Urea to promote root development.

    Timing :

    In rainfed systems, apply before rains;
    for direct-seeded rice, use during sowing
    for early-stage uptake.

    Organic Integration :

    Combine TSP with compost or
    manure to enhance phosphorus
    availability and soil health.

    Microbial Boost :

    Use phosphate-solubilizing
    microorganisms to improve TSP efficiency
    in no-tillage or rainfed soils.

    Soil Testing :

    Adjust dosage based on soil
    nutrient levels to prevent
    over-application.

    Can TSP be effectively integrated with organic manure or biofertilizers commonly used in Indian farming systems?

    Yes, TSP works very well with organic manure and biofertilizers in Indian farming systems.

    Why It Works :

  • Organic manure releases acids that make phosphorus from TSP more available to plants. Manure also improves soil structure and water holding capacity, aiding phosphorous uptake
  • Biofertilizers like Phosphate-Solubilizing Bacteri (PSB) improve TSP efficiency by making phosphorus easier for plants to absorb.
  • Combining TSP with organic inputs improves soil health and reduces chemical fertilizer dependence.
  • How to Use :

  • Mix TSP with decomposed manure and apply near plant roots.
  • Use biofertilizers like PSB or Rhizobium for crops like legumes to boost phosphorus and nitrogen availability.
  • Apply manure a few weeks before planting and TSP during planting for best results.
  • How effective is TSP in addressing phosphorus deficiency in Indian soils, particularly in phosphorus-deficient states?

    Highly Effective for Phosphorus Deficiency :

    TSP contains 46% water-soluble phosphorus, making it an
    excellent source for quickly addressing phosphorus deficiencies in crops.

    Targeted Application :

    TSP is best used in band placement
    near the root zone, ensuring maximum
    uptake by plants and reducing
    phosphorus fixation in the soil.

    It is suitable for crops like wheat,
    rice, maize, and legumes, which have
    high phosphorus demand.

    What is the impact of calcium on calcareous soils?

    Nutrient Lock-Up:

    High calcium in calcareous soils ties up nutrients like phosphorus, iron, and zinc, making them less available to crops.

    SOLUTIONS:

    Use phosphorus fertilizers like TSP with biofertilizers to reduce nutrient fixation.

    Effect on Crops:

    Crops like wheat, maize, and legumes struggle in these soils due to nutrient deficiencies, while calcium-tolerant crops like barley perform better.

    Add compost or organic

    manure to improve nutrient availability.

    Soil Challenges:

    Calcium can improve soil structure in some cases but may also cause compaction if soils are poorly managed

    Apply gypsum if sodium is a problem, to improve soil health.

    Impact of TSP on soil health?

    Phosphorus (P₂O₅):
    46% (highly concentrated phosphorus source).

    Calcium (Ca):
    Min 15% (as calcium sulfate or calcium phosphate,
    depending on composition).

    How is the uptake of TSP by plants?

    Phosphorus Availability:

    TSP provides water-soluble phosphorus that plants can easily absorb as phosphate ions (H₂PO₄ and HPO₄²).

    Conditions for Uptake:

    Works best in soils with a pH of 6.0–7.5 and needs enough soil moisture to dissolve and release nutrients.

    Best Application:

    Place TSP near the roots (band placement) for better uptake and to reduce loss due to soil reactions.

    Impact on Plants:

    Promotes strong root growth, early plant development, and better crop yields, especially in crops like wheat, maize, and legumes.

    Impact of TSP on soil health?

    POSITIVE EFFECTS:

    POSITIVE EFFECTS:

    Improves Phosphorus Levels:

    TSP provides readily available phosphorus, enhancing soil fertility and supporting crop growth.

    Calcium Addition:

    Contains calcium, which can improve soil structure and benefit crops in acidic soils.
    TSP positively impacts soil fertility by increasing phosphorus and calcium levels but requires balanced use and integration with organic matter to maintain long-term soil health.
