Villages throughout Maharashtra’s sugar belt usually experience the same hidden problem at the outset of each year’s first significant monsoon rain. While fields appeared green and healthy at the start of the monsoon season (June), by the end of the monsoon season (August) they will have turned an unsightly yellow-brown colour and, in some instances, will have developed patches of no sugarcane. Why do the sugarcane crops look dead, even though there has been sufficient precipitation? The answer to this question can be answered between Kolhapur, Sangli, Satara and Solapur; the problem is not caused by the quantity of rainfall provided by the monsoon. Instead, the combined effect of heavy rainfall and wet soil (the moisture level of the soil) has created a problem.

 

Why Monsoon Is Both a Blessing and a Challenge for Sugarcane

Sugarcane is a heavy feeder. It grows with a sustained and consistent need for nutrition, coupled with an established root system throughout its prolonged growing cycle. Monsoon waters, whilst appreciated, may wash away key nutrients, raise soil pH in some areas, compact the topsoil, and cause waterlogging which can kill roots. Efficient management of sugarcane growth during the monsoon should not just be limited to watering and weeding. Soil health should be actively nurtured while retaining nutrient availability and root strength from the ground.

 

The Two Biggest Monsoon Problems in Sugarcane Fields

Soil pH Imbalance and Nutrient Lockout

More watering, excesses fertilizer application create nutrient bounding in the soil. This results in very high pH levels in the soil that can cause a number of important nutrients (phosphorus, zinc, and iron) to be unavailable to plants, even when they are applied as fertilizer. Sugarcane roots will not be able to take up the nutrients that are locked up in the soil because of the effect of rain on soil chemistry. Neutralite is a granular, all-natural soil acidifier and pH corrector from Kay Bee Bio-Organics that helps to re-balance soil pH, unlock nutrients that are tied up in the soil, and increase the availability of nutrients in the plant’s root zone. By bringing the pH of the soil back to normal levels during the monsoon season, it is critical that you use Neutralite to ensure that the fertilizer you have added to the soil is making its way into the plant and is not being wasted in the soil.

 

Weak Root Development and Poor Phosphorus Uptake

The roots are restricted from growing and getting oxygen when soils become waterlogged or compacted due to the rains. Sugarcane relies heavily on an extensive and functioning root system to stabilize the plant effectively. This is exactly where monsoon sugarcane nutrition needs a biological approach, not just chemical inputs.

Mycoris is a mycorrhizal biofertilizer from Kay Bee Bio-Organics that will introduce beneficial fungi (VAM – Vesicular Arbuscular Mycorrhizae) into the crop’s root zone. Mycoris helps to form a symbiotic network of fungi that will greatly increase the effective surface area of the root and improve phosphorus assimilation, drought tolerance, and resilience to root stress.

In sugarcane using a mycorrhiza product like Mycoris during tillering and early grand growth phase strengthens the very foundation of your crop.

 

A Practical Monsoon Nutrition Plan for Sugarcane

Here is a simple, field-ready approach to monsoon sugarcane nutrition:

Apply Neutralite as a soil treatment to correct pH and prepare the root zone for nutrient absorption. Work it into the soil near the root zone for best results. 

At tillering stage: 

Apply Mycoris along with your regular fertilizer schedule. The mycorrhizal fungi establish quickly in moist monsoon soils and begin extending root networks within weeks. 

Monitor for waterlogging. Combine sugarcane bio fertilizer inputs like Mycoris with balanced NPK to reduce over-reliance on chemical fertilizers and improve nutrient retention.

 

Why Botanical & Biological Solutions Work Better in the Monsoon

Applying chemical fertilizers in times of heavy rain causes them to run off and leach easily. Whereas botanical & biological inputs (such as pH correctors and mycorrhiza) will work with the soil system, rather than against it, and increase the soil’s capacity to hold/ deliver nutrients, resulting in less waste of input materials and a better return on investment. Farmers who add 4 kg per acre of Neutralite and 2- 4 kg per acre of Mycoris to their monsoon program generally find that they have more uniform stalks, stronger roots, and are less likely to experience mid-season nutrient stress.

 

Conclusion 

Sugarcane growth management in monsoon is not about doing more; it is about doing the right things at the right time. Healthy soil pH and a strong root system are two core elements of an overall sugarcane management system. If you have been harvesting below where you feel that you should be based on normal rainfall and fertilizer applications, you might want to take a closer look at what is going on below the ground, as both the soil and roots are very much influencing your yield. First things should be first, correct your pH with Neutralite and develop your roots with Mycoris; your sugarcane plants will take care of the rest.
