Crop rotation can help restore tilth in compacted soils. Proper management of agricultural soils can positively impact soil aggregation and improve tilth quality. Such stable aggregates break apart during tillage/planting and readily provide good tilth. Soil management problems also include water erosion, cotton root rot, soil tilth, and brush control. Roots only grow where the soil tilth allows for adequate levels of soil oxygen. When they are tilled the result is often a very cloddy surface (poor tilth). Glomalin gives soil its tilth (texture), buoyancy and water absorption ability. Soil with good tilth has large pore spaces for air infiltration and water movement. Soil tilth can be obtained through mechanical and biological manipulation. Such soils natively have little tilth, especially once they have been disturbed. Crop rotation and cover crops can positively impact tilth. Buck, Rippon, Bearns, Farrow, Tilth and Shoaks. The farm is certified organic by Oregon Tilth. Oregon Tilth is an Accredited Certifying Agent (ACA) for the USDA's National Organic Program. Hines worked with Nora Pouillon and Oregon Tilth to have the restaurant certified organic.
