Sugarcane is one of the world’s most important commercial crops, supporting the sugar, ethanol, and bioenergy industries. As a long-duration crop with high biomass production, it requires substantial quantities of nutrients throughout its growth cycle. However, continuous dependence on chemical fertilisers alone can gradually reduce soil fertility, weaken soil biology, and lower nutrient-use efficiency.
Integrated Nutrient Management (INM) offers a sustainable solution by combining organic fertilisers, biofertilisers, balanced chemical fertilisers, liquid nutrients, and soil conditioners to maintain soil fertility while maximising crop productivity. This integrated approach not only improves nutrient availability but also enhances soil health and ensures consistent cane yields over the long term.
Narmada Bio-Chem Limited (NBCL) provides a comprehensive range of organic fertilisers, biofertilisers, and liquid nutrient solutions that support every stage of sugarcane cultivation while promoting sustainable agriculture.
What is Integrated Nutrient Management
Integrated Nutrient Management (INM) is the practice of supplying crops with nutrients through a balanced combination of:
-
- Organic fertilisers
- Crop residues
- Biofertilisers
- Soil conditioners
- Chemical fertilisers
- Liquid nutrients
- Micronutrients
Rather than relying on a single nutrient source, INM ensures complete and balanced nutrition throughout the crop cycle.
For sugarcane, this approach improves nutrient-use efficiency, reduces fertiliser losses, enhances soil fertility, and supports consistently higher cane yields.
Why Sugarcane Needs an Integrated Approach
Sugarcane removes large quantities of nutrients because of its long growing period and high biomass production. Continuous cultivation without replenishing soil nutrients often leads to declining fertility and lower productivity.
Common nutrient-related challenges include:
-
- Nitrogen deficiency
- Poor phosphorus availability
- Potassium depletion
- Zinc deficiency
- Declining organic carbon
- Reduced microbial activity
Integrated Nutrient Management addresses these challenges by improving both nutrient availability and soil health.
Building the Foundation with Organic Fertilisers
Organic matter forms the backbone of every successful INM programme.
NBCL’s organic fertilisers, such as Bio Gold and Powerphos/PROM, enrich the soil with organic matter while improving soil fertility naturally.
1. NBCL Bio Gold
Bio Gold improves soil quality by:
-
- Increasing soil organic carbon
- Improving soil structure
- Enhancing water-holding capacity
- Promoting beneficial microbial activity
- Improving nutrient retention
- Supporting long-term soil productivity
2. NBCL Powerphos/PROM
Powerphos/PROM combines the benefits of organic manure with phosphorus nutrition.
Regular application helps:
-
- Improve phosphorus availability
- Encourage stronger root development
- Enhance microbial activity
- Improve flowering and cane establishment
- Increase soil organic matter
- Support sustainable crop production
Healthy soils enriched with organic fertilisers create the ideal environment for beneficial microorganisms introduced through biofertilisers.
Improving Nitrogen Availability Naturally
Nitrogen is one of the most important nutrients for sugarcane growth, supporting tillering, leaf development, and cane elongation.
Along with recommended fertiliser doses, NBCL Azotobacter and NBCL Azospirillum improve nitrogen availability through biological nitrogen fixation and plant growth promotion.
These beneficial microorganisms contribute to:
-
- Better root development
- Improved tillering
- Vigorous vegetative growth
- Enhanced nutrient uptake
- Improved soil microbial activity
Unlocking Phosphorus with NBCL PSB
Phosphorus is essential for root establishment, energy transfer, and early crop growth. However, much of the phosphorus present in agricultural soils becomes chemically fixed and unavailable to plants.
NBCL Phosphate Solubilising Bacteria (PSB) converts insoluble phosphorus into plant-available forms through natural microbial activity.
Improved phosphorus availability supports:
-
- Strong root systems
- Better tiller formation
- Increased shoot growth
- Improved cane development
- Enhanced sugar accumulation
Mobilising Potassium for Better Cane Quality
Potassium plays a crucial role in sugar transport, water regulation, enzyme activation, and disease resistance.
NBCL BIO KMB (Potassium Mobilising Bacteria) mobilises fixed potassium, making it readily available throughout the growing season.
Improved potassium nutrition helps:
-
- Increase cane weight
- Improve juice quality
- Enhance sucrose accumulation
- Improve drought tolerance
- Strengthen disease resistance
Correcting Micronutrient Deficiencies
Micronutrients are required in small quantities but have a major influence on sugarcane productivity.
1. NewTrient Zinc 39.5%
Zinc deficiency is common in many sugarcane-growing regions and can significantly reduce plant vigour and cane yield.
NBCL NewTrient Zinc 39.5% supplies highly available zinc that supports:
-
- Healthy chlorophyll formation
- Better enzyme activity
- Improved photosynthesis
- Stronger plant vigour
- Improved cane growth
- Higher yield potential
2. NewTrient 11-11-8 with Zinc & Boron
NBCL NewTrient 11-11-8 with Zinc & Boron provides balanced nutrition together with essential micronutrients during active crop growth.
Its balanced formulation supports:
-
- Uniform crop growth
- Better tillering
- Improved cane development
- Enhanced sugar accumulation
- Improved nutrient-use efficiency
Integrating these liquid nutrient formulations into an INM programme ensures both macro- and micronutrient requirements are met efficiently.
Balanced Nutrition with NBCL BIO NPK
NBCL BIO NPK contains beneficial microbial consortia that naturally improve the availability of nitrogen, phosphorus, and potassium simultaneously.
Its benefits include:
-
- Better nutrient cycling
- Improved root development
- Uniform crop growth
- Enhanced fertiliser-use efficiency
- Higher biomass production
When used alongside organic fertilisers and balanced fertiliser schedules, BIO NPK becomes an important component of Integrated Nutrient Management.
Strengthening Root Systems with Mycorrhiza and Muladhar
Healthy roots are essential for efficient nutrient absorption.
NBCL Mycorrhiza extends the effective root system through fungal hyphae, enabling plants to absorb more phosphorus, water, and micronutrients.
NBCL Muladhar supports healthy root-zone biology by improving microbial activity around the root system.
Together they help:
-
- Improve root growth
- Enhance nutrient uptake
- Increase water-use efficiency
- Improve tolerance to environmental stress
- Support stronger cane development
Improving Soil Health Through Biological Activity
Integrated Nutrient Management focuses not only on feeding the crop but also on feeding the soil.
Regular use of biofertilisers encourages beneficial microorganisms that:
-
- Decompose organic matter
- Improve nutrient cycling
- Enhance soil aggregation
- Increase microbial diversity
- Improve long-term soil fertility
Healthy soils provide a sustainable foundation for higher sugarcane productivity season after season.
Best Practices for Integrated Nutrient Management in Sugarcane
To maximise the benefits of INM, farmers should adopt a balanced nutrient management programme.
Recommended practices include:
-
- Apply NBCL Bio Gold or Powerphos/PROM before planting to improve soil organic matter.
- Incorporate crop residues wherever possible to increase soil organic carbon.
- Use NBCL BIO NPK to improve nitrogen, phosphorus, and potassium availability.
- Apply NBCL PSB and BIO KMB to enhance phosphorus and potassium uptake.
- Include NBCL Azotobacter and Azospirillum to strengthen nitrogen availability.
