Overview

Neem cake is what remains after neem seed kernels are crushed for oil. It carries roughly 4–5% nitrogen along with some phosphorus and potassium, but its value goes beyond the nutrient figures: the residual neem compounds (azadirachtin and others) suppress soil-borne pests, white grubs and plant-parasitic nematodes.

Because its nitrogen is released slowly as soil microbes break it down, neem cake feeds the crop steadily rather than in a flush, and it is widely used to coat or blend with urea to slow that fertiliser’s release too. It is a genuinely dual-purpose input — fertiliser and soil-pest management in one.

What it is and when to reach for it

  • An organic, slow-release nitrogen source that also suppresses white grubs, termites and nematodes — reach for it on nematode-prone and soil-pest-prone fields.
  • It is a partner to your main nutrition, not a full NPK replacement, since its nutrient percentages are modest.
  • It is a favourite in organic and low-chemical systems, and for high-value vegetables and orchards.

How to use it well

  • Apply about 80–200 kg/acre as a basal soil application, worked into the topsoil before or at sowing/planting.
  • Blend it with urea (roughly 5:1 urea:neem cake) to slow urea’s nitrogen release — a low-cost, farm-level version of neem-coating.
  • Use it around the root zone of vegetables and fruit trees where nematodes are a problem.

Common mistakes

  • Expecting a quick green-up — its nitrogen is deliberately slow, so it complements rather than replaces urea for a fast response.
  • Treating its nutrient content as a full basal dose and skipping DAP/MOP where the crop needs them.
  • Storing it damp, which lets it rot and lose both nutrients and neem activity.

Common questions

Is neem cake a fertiliser or a pesticide?

Both, in effect. It supplies slow-release nitrogen (about 4–5%) as an organic fertiliser, and its residual neem compounds suppress soil pests, white grubs and plant-parasitic nematodes. That dual action is exactly why farmers value it.

How much neem cake per acre?

A common rate is about 80–200 kg per acre as a basal soil application, worked into the topsoil at sowing or planting. On nematode-prone vegetable and orchard soils it is applied around the root zone.

Can neem cake be mixed with urea?

Yes — blending neem cake with urea (roughly 5 parts urea to 1 part neem cake) slows the release of nitrogen, much like commercial neem-coated urea, so more of it reaches the crop. Mix only what you will apply.
