Mustard Cake Fertilizer: A Nutrient Powerhouse with Added Plant Protection.

Liquid Fertilizer made of Mustard cake, also known as Sarso ki Khali, is an organic manure that’s gaining recognition among home gardeners. Its popularity arises from its nutrient-rich composition and its ability to nurture beneficial microbial populations that protects your plants from pest and disease..

Whether you have potted plants on your balcony or a small vegetable garden in your backyard, Mustard cake fertilizer can be your go-to choice. Now, let’s go deep into the secret behind its nutrient-rich treasure: the fermentation method.

The Fermentation Process: The 20-40 method.

The secret to the nutrient-rich treasure of Mustard cake fertilizer lies in the fermentation process, boosted by the addition of jaggery. This is how it’s prepared using 20-40 method:


Mustard cake (0.5 Kg)
Water (2 liters)
Jaggery (50 grams to enhance microbial activity)


Mixing: Start by thoroughly mixing 0.5 kilograms of Mustard cake with 2 liters of water. This forms the basis of the Mustard cake liquid fertilizer.

Adding Jaggery: To supercharge the fermentation process, add jaggery. Jaggery acts as a microbial stimulant, encouraging the growth and activity of beneficial microorganisms in the mixture. These microorganisms are essential for breaking down complex organic compounds into simpler forms like NPK and plant micronutrients that are more readily absorbed by plants.

Fermentation: The magic happens during the extended fermentation period, which typically lasts for 20 days initially, with further improvements observed at the 40-day mark. During this time, the Mustard cake, water, and jaggery mixture is left to sit. It is in this period that the transformation of nutrients takes place. This is 20-40 method of making Mustard Cake Liquid Fertilizer

By incorporating jaggery into the fermentation process, you can enhance the microbial activity, leading to a more potent and nutrient-rich Mustard cake liquid fertilizer for your home garden.

Fermentation Magic: Boosting Mustard Cake Fertilizer Nutrients by 5x

In the world of organic gardening, the extended fermentation process works like magic, helping to significantly boost nutrients. It is during this time that the Mustard cake and water concoction undergoes a remarkable transformation, resulting in nutrient-rich Mustard cake liquid fertilizer.

20 Days After Fermentation:

At the 20-day mark, the Mustard cake liquid fertilizer reveals its nutrient-rich potential:

Nitrogen (N): The most striking transformation occurs in nitrogen content. On the day of preparation, the solution contains 1540 ppm of nitrogen. However, at the 20-day mark, this figure skyrockets to an impressive 8358 ppm. This dramatic increase indicates that Mustard cake fertilizer becomes an even richer source of nitrogen as it matures, perfect for promoting healthy leafy growth in your plants.

Phosphorus (P): Phosphorus, another vital nutrient for plant growth, also exhibits significant changes. While the solution starts with 68.898 ppm of phosphorus, it surges to 284.449 ppm at the 20-day mark. This suggests that Mustard Cake Liquid Fertilizer becomes increasingly effective in providing phosphorus to your plants as it ages, aiding in robust root development.

Potassium (K): The content of potassium, an essential macronutrient, experiences substantial growth over the 20-day period. Starting at 503.498 ppm, it reaches 1147.445 ppm. This rise in potassium levels is particularly beneficial for plant development and overall crop health, enhancing disease resistance.

Micro and Macronutrients: Calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), copper (Cu), and manganese (Mn) all demonstrate notable increases in concentration. These essential micronutrients play critical roles in plant growth, from strong cell structure to nutrient absorption and disease prevention.

Many fold increase in Beneficial Microbes population: As the fermentation process goes on, something special happens. Not only do the nutrients get stronger, but good microbes also start to multiply. One of these helpful microbes is Pseudomonas. Think of them as the protectors of your plants, keeping harmful things away. They’re like a shield that helps your garden stay healthy all on its own. And after 20 days, there are loads of them – about 7 x 10^4 cfu/ml – making sure your plants are safe.

But that’s not all. There’s another amazing microbe in the mix, Trichoderma. These tiny warriors are experts at fighting off diseases that can come from the soil. When they’re in Mustard Cake Liquid Fertilizer, it becomes even better. By day 20, their numbers have gone up a lot – to about 11 x 10^5 cfu/ml. They’re working hard to make sure your plants stay strong and disease-free.

40 Days After Fermentation:

The nutrient content of Mustard cake liquid fertilizer continues to evolve at the 40-day mark, providing even more insights into its potential as a liquid fertilizer:

Nitrogen (N): The nitrogen content, which had already increased significantly by the 20-day mark, remains high at 7358.42 ppm. This suggests that this liquid fertilizer retains its impressive nitrogen levels over an extended period, promoting vibrant foliage in your garden.

Phosphorus (P): Phosphorus content also continues to rise, reaching 195.886 ppm. This demonstrates that the Sarso Khali liquid fertilizer becomes an increasingly valuable source of phosphorus as it matures, essential for flowering and fruiting.

Potassium (K): The potassium content peaks at 1741.043 ppm, emphasizing the Mustard cake ability to deliver potassium to your plants effectively, enhancing fruit quality.

Micro and Macronutrients: Calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), copper (Cu), and manganese (Mn) maintain their increasing trends, showcasing the Mustard cake Mustard cake liquid fertilizer consistent nutrient enrichment, contributing to overall plant resilience.

Further increase in Beneficial Microbes population

At the 40-day mark,  Trichoderma, continues to thrive. Their populations surged to an impressive 18 x 10^5 cfu/ml, diligently safeguarding your plants and ensuring they stay healthy and disease-free. Similarly, Pseudomonas populations also increased to 17 x 10^4 cfu/ml, further enhancing their role in plant protection.
