The great savior of grassland

Australia is a vast area, suitable for the growth of forage, and has many natural pasture, rich groundwater, which creates conditions for the development of animal husbandry.

In 1770, Australia introduced cattle, vigorously developed cattle raising industry, and the increase of beef price in the international market further stimulated the development of cattle industry, and the number of cattle in Australia increased rapidly.

But a headache has arisen: as the number of cattle increases, cattle on the grassland also excrete more and more feces, leaving about 100million kilograms of manure per day. These feces cover the grass, affect the photosynthesis of plants, cause the grass to die, and cause desertification of grassland. At the same time, there are a large number of mosquitoes and flies in the feces, which seriously affect the environmental health. People are worried about this.
