The Punjab government promotes sustainable soil management practices like:

Organic farming
Zero tillage
Precision agriculture
All of the above

The correct answer is: d) All of the above.

The Punjab government promotes sustainable soil management practices like organic farming, zero tillage, and precision agriculture.

Organic farming is a method of crop and livestock production that involves much more than choosing not to use pesticides, fertilizers, genetically modified organisms, antibiotics and growth hormones. Organic production is a holistic system designed to optimize the productivity and fitness of diverse communities within the agro-ecosystem, including soil organisms, plants, livestock and people. The principal goal of organic production is to develop enterprises that are sustainable and harmonious with the environment.

Zero tillage is a type of farming that minimizes soil disturbance. It involves planting seeds directly into the soil without disturbing the residue from the previous crop. This can help to reduce erosion, improve water infiltration, and conserve soil nutrients.

Precision agriculture is a farming management concept based on observing, measuring, and responding to variability in agricultural production. It uses information technology to collect and analyze data on soil, crop, and weather conditions, and then uses this information to make decisions about crop management, such as when to plant, fertilize, and irrigate.

All of these practices can help to improve soil health and productivity, and reduce the environmental impact of agriculture.
