Major crop nutrient fertilizers (nitrogen, phosphorus and potassium (NPK)) are typically applied in powdered (small particles), granular (larger particles) or in liquid form either as individual or as compound fertilizers. The fertilizer may be applied using a combine (corn) drill where the seed is contained in one hopper and dry fertilizer in another behind it.
Because India's economy was growing slowly, a slower rate of mechanization and a larger volume of migration could have solved the labor shortages in Punjab at a lower capital cost. And the extra employment would have meant that the benefits of the green revolution were shared more widely with workers in poorer regions.
