Crop rotation means growing different crops in sequence on the same field instead of the same crop every season, which restores fertility and breaks pest and disease cycles. Alternate deep-rooted and shallow-rooted crops and include a legume (pulse) that fixes nitrogen, for example cereal then pulse then oilseed. This reduces buildup of crop-specific pests, weeds, and diseases, improves soil structure and organic matter, and balances nutrient use because different crops draw different nutrients. Plan rotations around your soil, water, market, and labour, and avoid following a crop with a close relative that shares the same pests. Combined with green manure and residue management, rotation steadily lowers your input cost.

Slotting a pulse between two cereals visibly cut my urea bill the following season, since the legume left nitrogen behind in the soil. The pulse also gave a bit of extra income.

Do not follow tomato with chilli or brinjal, they share the same wilt and pests, and I learned that the hard way. Rotating to an unrelated family broke the disease cycle in my vegetable plot.

Plan the rotation around water and market, not just soil. A water-hungry crop after a dry-season crop strained my borewell, so I now line up the sequence with what I can actually irrigate and sell.

Deep-rooted crops alternated with shallow ones helped break my hard subsoil layer over time. The deeper roots open channels that the next crop's roots and water follow.

A diagnostic habit: keep a simple plot-wise record of what grew where each season. After a couple of years it stops you from accidentally repeating the same family on the same plot, which is when pests build up. Pair it with residue return and green manure for the best soil gain.
