The Loop · Proof & results
Not a claim. Measured in the field.
A farmer should not change how he farms on faith. Every part of the loop is tested, recorded and checked by institutions that have nothing to sell him. Here is what the evidence says so far.
30 → 117MT sugarcane, validated by VSI
402crops with a protocol
70+certified bio-inputs
The headline result
30→117MT Produce
Sugarcane taken from 30 to 117 tonnes in three years, 3.9 times, with 100% organic produce and 100% organic soil. The field work was validated by the Vasantdada Sugar Institute, Pune, India's leading sugarcane research institute.
The VSI validation covers Shri Sutra, the root layer of the protocol, made with Warkem. Results depend on crop, soil, season, protocol discipline and monitoring.

Inside the VSI field trials
More cane, more sugar, more life in the soil.
Measured in VSI trials with Warkem organics alongside a reduced chemical fertiliser dose.

Beyond sugarcane
The same inputs, with results on eight crops, to name a few.
Farmers use Shri Sutra (Warkem) inputs across the crops on the protocol list. Here are trial results reported by universities and research institutes on a few of them, compared with standard practice or an untreated control.
