The polar air masses are air masses that form on the high latitudes, in the polar regions. The tropical air masses are air masses that form on the low latitudes, around the equator.
The polar air masses are cold air masses. They are also dry, very dense, and have much higher air pressure. The tropical air masses are warm air masses. Depending have they formed over land or over sea, they can be either dry or moist, and they have low air pressure as they are much less dense.
A typical polar air mass brings in cold and dry weather, while the tropical air mass brings in warm weather, with either lot of precipitation, or being very dry.
The polar air masses are moving from the high latitudes toward the lower latitudes, while the tropical air masses are moving from the lower latitudes toward the higher latitudes.

(I'll answer the last question first)
The diffusion of agriculture, as theorized by Carl Sauer, a cultural geographer, notes that the earliest form of agriculture was vegetative planting. Then the process of seed planting occurred some time later. After the early human settlement has developed more of farming methods.
Vegetative planting is characterized by cutting the stems of a plant, or dividing part of its roots and transplanting them into soil. This was believed to be the first method, as it was in this method the early human tried to wild plants nearer to their settlements for easier access to food.
While on the other hand, Seed planting was a newer technology for the early humans. It involves the collection of the fruit and drying of seed to be planted. It is also happen in annual basis unlike the transfer of stems and roots of wild plants.
