There are roughly 12 nutrients used by most plants:

Major nutrients: Nitrogen, Phosphorus, Potassium

Secondary nutrients: Sulfur, Magnesium, Calcium

Minor nutrients: Iron, Manganese, Chlorine, Boron, Zinc, Copper (if I remember correctly)

The key to stabilizing the Earth's climate lies through regenerative agriculture focused on building soil organic matter through integrated animal and plant ecosystem management. Organic matter is mostly Carbon, and this is taken from the atmosphere. Most mono-cropped soils have less than 1% organic matter, while pasture soils have 5-6% and virgin prairie has over 10%.

The stereotypical cow is the Holstien-Fresian. While these cows produce large volumes of milk, their milk has less nutrients and the cows themselves have boring personalities. Of the six major milking cattle breeds, Holstiens are the most abundant, followed by the Jersey, whose smaller size, nutrient-rich milk, and playful, intelligent personalities make them popular as family pets and producers.

That enough? I tried to make it varied.
