The evidence, and where it runs out.

Soil Poverty: Punjab’s Potash. As potash runs short, urea and DAP buy less yield.
Punjab’s crops take about 940,000 tonnes of potash out of the soil a year; fertilizer puts back 36,000. Most of 20,000 model runs put the Punjab average below 100 ppm between 2027 and 2044. A report by Tahir Abbas, with the full PDF.
Every nutrient a crop eats, and why the shortest one decides the harvest.
What each of the 17 does, what a crop looks like without it, which ones work as pairs, and a barrel you can put your own bags into. Liebig’s Law of the Minimum, for a Pakistani field.
Pakistan is not short of fertilizer. It is short of nutrition that reaches the crop.
Usage, balance, productivity, and where the nitrogen actually goes. Measured against India, Bangladesh, China and the United States, with every source named.
We have been spending the soil’s capital, not its income.
A harvest is an export. 6 published surveys on where the soil has ended up, and the national dataset Pakistan does not have.
A bag is not a dose. How nutrient is delivered is part of the product.
Pivot, drip, drone, broadcast, fertigation and foliar. What each one demands of the product, the 2 field programmes VAN has run of its own, and One Tank, the family built around the 20 litres a drone can carry.
Pakistan’s nutrient data, to explore yourself.
Interactive charts: fertilizer per acre against any country, the balance between nutrients, what comes back in the harvest, and where Punjab’s soil potash is heading.
