Press mud Nutrient Calculator
Value the N-P₂O₅-K₂O in press mud (sugar filter cake) (~1.5:3:1%) and the urea, DAP and MOP it replaces, with first-year nitrogen availability accounted for.
Press mud (sugar-mill filter cake) is unusually phosphorus-rich (≈1.5-3.0-1.0% N-P-K) and a fine soil conditioner near sugar belts. Compost it first; fresh press mud can immobilise nitrogen as it decomposes.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.
Organic and integrated-nutrient farmers use the free Press mud Nutrient Calculator to put a rupee value on their press mud (sugar filter cake) and work out how much bagged fertilizer they can safely cut back.
About Press mud Nutrient Calculator
Press mud — the filter cake from sugar mills — is a cheap, phosphorus-rich amendment (about 1.5-3.0-1.0% N-P₂O₅-K₂O) wherever cane is crushed. Composted press mud improves soil structure and supplies notable P. This tool values its NPK; remember fresh press mud can briefly tie up soil nitrogen as it rots.

Frequently asked questions
What is the nutrient value of press mud (sugar filter cake)?+
Press mud (sugar filter cake) typically analyses around 1.5% N, 3% P₂O₅ and 1% K₂O. Roughly 30% of the nitrogen is available in the first year; the rest builds soil over following seasons.
Why is only part of the nitrogen counted the first year?+
Organic nitrogen is locked in complex compounds that soil microbes mineralise gradually. About 30% becomes plant-available in year one for press mud (sugar filter cake); the carry-over keeps feeding later crops, which is why organic matter improves long-term fertility.
How and when should I apply it?+
Press mud (sugar-mill filter cake) is unusually phosphorus-rich (≈1.5-3.0-1.0% N-P-K) and a fine soil conditioner near sugar belts. Compost it first; fresh press mud can immobilise nitrogen as it decomposes.
