Soil Health Card organic carbon reading interpretation, low OC meaning, how to improve in field crops.
My Soil Health Card shows organic carbon 0.3 percent, is that low and how do I raise it?

An organic carbon (OC) value of 0.3 percent is in the low category; most labs rate below 0.5 percent as low, 0.5 to 0.75 as medium, and above 0.75 as high, though exact bands vary by lab. Low OC means weak soil structure, poor water holding, and low microbial activity, so your fertiliser response also drops. Raise it slowly by adding 2 to 4 tonnes of well rotted FYM or compost per acre, returning crop residue instead of burning, growing a green manure like dhaincha, and including a legume in rotation. Do not expect a jump in one season; OC usually rises by a small fraction over several years of steady organic addition. Re-test through your Soil Health Card every 2 to 3 years and adjust to your soil test and local KVK; do not over apply.

My card was also 0.32. After three years of FYM plus mulching the residue it crept up to 0.45. Slow but it shows in better moisture during dry spells.

Do not burn your paddy or wheat stubble. I started mixing it back into the field with a happy seeder and the soil feels softer and darker now. Burning it sends all that carbon up in smoke and kills the surface life that you actually want.

One thing many of us miss is that vermicompost on top of plain FYM speeds things up. I started a small vermicompost bed at home from cow dung and farm waste, and using even 1 tonne per acre of it along with green manure made a visible difference in two seasons. The cost is mostly your labour.

In our area the cheapest carbon boost was simply not burning the residue and growing dhaincha in the gap before sowing. Two seasons of green manure plus dung and my black soil started holding moisture better. The reading on the next card had nudged up too.

One caution from me: do not dump huge loads of raw, half rotten dung thinking it raises carbon faster. The first year I used fresh cattle dung it actually pulled nitrogen and the wheat looked pale early. Well rotted FYM or compost is the safer way to build it slowly.
