‘Grasslands Milford’ dryland browntop (Agrostis castellanaBoiss. & Reut.)

New Milford

Established in 1990, the New Milford Farms (NMF) composting facility serves as a low-cost means of disposal for various industrial residues from Nestle USA, a large international food company. The NMF facility takes in organic feedstocks ranging from spent coffee grounds and industrial wastewater sludge to leaves and brush from nearby residents, and combines them to create fertilizing compost u...

Dryland Agriculture: Sociology

Carbon sequestration in dryland ecosystems.

Drylands occupy 6.15 billion hectares (Bha) or 47.2% of the world's land area. Of this, 3.5 to 4.0 Bha (57%-65%) are either desertified or prone to desertification. Despite the low soil organic carbon (SOC) concentration, total SOC pool of soils of the drylands is 241 Pg (1 Pg = petagram = 10(15)g = 1 billion metric ton) or 15.5% of the world's total of 1550 Pg to 1-meter depth. Desertification...

Dryland Rivers: Processes and Forms

Dryland alluvial rivers vary considerably in character. In terms of processes, high energy, sediment-laden flash floods in upland rivers contrast dramatically with the low sediment loads and languid flows of their lowland counterparts while from a form perspective, the unstable wide, shallow and sandy braid plains of piedmont rivers are quite different from the relatively stable, narrow, deep a...

Functioning in Grasslands

Grasslands are the potential natural ecosystem type on approximately 25% (33x lo6 km2) of the land surface of the earth (Shantz 1954). Current estimates of the global extent of grasslands range from 16% (Whittaker and Likens 1973, 1975) to 30% (Ajtay et al. 1979). The difference between the estimates of the potential extent of grasslands and the current extent provides an indication of the degr...
