Neem Cake & Dose the Soil Right
Suppresses nematodes
Enter your area and the per-acre rate to get the total neem cake to apply, the number of bags, the organic nitrogen it supplies and the rate per acre — to fight soil pests and feed the soil.
Plan your application
Next: broadcast 200 kg (4 bags) and incorporate before sowing, ideally with FYM; it also blends well with urea to cut N loss.
Rate varies by crop/pest pressure; neem cake is also a mild fertiliser (~5% N) — store dry to keep its azadirachtin potency.

Protect the root zone and feed the soil at once
Neem cake earns its place in the field twice over. Worked into the soil before sowing it suppresses root-knot nematodes, white grubs and other soil-borne pests without leaving a harmful residue; at the same time it slows the nitrification of urea so applied nitrogen stays available longer, and it adds organic matter and about 5% nitrogen of its own. Getting the dose right means buying the correct quantity and spreading it evenly — too little and the protection fades, too much and you waste money.
This tool turns your area and per-acre rate into the total kilograms, the number of bags, the organic nitrogen supplied and the rate per acre. Broadcast and incorporate the cake before sowing, ideally blended with well-rotted FYM into moist soil. Pair it with the Manure Application Rate, Neem Oil Spray and Biological Control Release tools for a complete, low-residue crop-protection plan.

Frequently Asked Questions
What does neem cake do in the soil?+
Neem cake is the residue left after oil is pressed from neem seed. Worked into the soil it suppresses nematodes, white grubs and other soil pests, slows the nitrification of urea so applied nitrogen lasts longer, and adds organic matter and roughly 5% nitrogen of its own. It is both a soil conditioner and a gentle, slow-release organic fertiliser.
How much neem cake should I apply per acre?+
A common soil-application rate is about 200–250 kg per acre, broadcast and incorporated before sowing. This tool multiplies your chosen rate by your area to give the total kilograms, the number of bags, and the organic nitrogen supplied, so you can buy and apply the right amount.
How does neem cake control nematodes and soil pests?+
Compounds in neem cake (azadirachtin and related limonoids) and the breakdown of its proteins disrupt the feeding and reproduction of root-knot and other nematodes, white grubs and many soil-borne pests. It works best worked evenly into the root zone before the crop is sown, giving lasting, residue-free suppression.
Why does neem cake make urea last longer?+
Neem cake slows nitrification — the microbial conversion of ammonium nitrogen to nitrate, which leaches and gases away. By holding nitrogen in the ammonium form for longer, neem-coated or neem-blended urea keeps more nitrogen available to the crop, improving use-efficiency and reducing losses.
How much nitrogen does neem cake supply?+
Neem cake contains roughly 5% nitrogen, along with smaller amounts of phosphorus and potassium and a range of micronutrients. The calculator estimates the organic nitrogen your dose supplies, which you can credit against the crop's nitrogen need when planning fertiliser.
When and how should neem cake be applied?+
Broadcast it evenly and incorporate it into the soil before sowing or transplanting, ideally mixed with well-rotted farmyard manure (FYM) to spread it and feed soil life. Apply to moist soil for best activity; avoid leaving it on the surface where it dries out and works poorly.
Can I mix neem cake with FYM or compost?+
Yes — blending neem cake with farmyard manure or compost is the recommended way to apply it. The bulky organic carrier helps spread a small quantity of cake evenly across the field, improves contact with the soil, and combines pest suppression with the broader benefits of organic matter.
Is neem cake safe and organic?+
Neem cake is a natural, biodegradable by-product accepted in organic systems. It is gentle on earthworms and beneficial soil organisms at normal rates, leaves no harmful residue, and improves soil structure over time — making it a safe alternative to synthetic soil insecticides.
Does this work for any crop or area unit?+
Yes — neem cake suits vegetables, plantation crops, orchards and field crops alike; just set the per-acre rate suitable for your crop and enter the area in acres, hectares, bigha, guntha or m². The calculator converts and gives the total, bags and nitrogen for any plot.
Are the figures precise?+
They are solid planning figures. Actual nitrogen and pest suppression vary with the cake's quality and oil content, soil moisture, temperature and how evenly it is incorporated. Buy from a reliable source, apply to moist soil, and treat the numbers as a guide for ordering and dosing.
