grazing

He had nearly a thousand acres of grazing and arable land.

They have also expanded into many areas lacking any agriculture other than grazing and into places without forests or permanent streams.

They required water at least every 24 hours and large tracts of grazing grass if herds of any size were to be maintained.

The secret was the careful selection of grazing land, especially in environments where seasonal rainfall led to marked differences in graze quality throughout the year.

The widespread distribution of pastoral sites of this period suggests that the Saharans ranged their herds over widely separated summer and winter grazing grounds.

In order to increase production on existing land, the peasants made more use of crop rotation and, in particular, began to apply animal waste to the soil regularly, rather than leaving the fertilization process up to the grazing livestock.

For instance, several kinds of birds feed on insects flushed out of the grass by grazing cattle.

The consequences of an excessive number of livestock grazing in an area are the reduction of the vegetation cover and the trampling and pulverization of the soil.

Some scientists have proposed that the presence of increasing levels of ultraviolet light with elevation may play a role, while browsing and grazing animals like the ibex may be another contributing factor.
