The Importance of Leaf Area Index (LAI) in Environmental and Crop Research
Leaf Area Index (LAI), which is used as a measure in hundreds of studies on forests, crops, climate and the environment, is calculated as half the area of all leaves per unit area of ground. It is measured as the leaf area (m2 ) per ground area (m–2) and is unit-less. So, a plant with a LAI of 2 has an amount of leaves that can cover a given area two times. LAI is calculated for a plant or ...

Landscape trees benefit from potassium-based superabsorbent polymer-amended backfill soil
Weiner (1975) put it aptly when he stated that “However rewarding the act of tree planting may be, watching a young tree slowly die can be spiritually defeating.” Landscape plants, noted Richard Harris (1983) in his well-known “Arboriculture” book, “probably suffer more from moisture-related problems than from any other cause.” The success of tree planting ...

Family farms can be competitive by focusing on conservation and stewardship
While the U.S. Department of Agriculture (USDA) reports a 40 percent decline in U.S. cropland soil erosion rates from 1982 to 2007, recent trends appear to challenge this progress. Record prices for corn and soybeans have diverted acres out of conservation programs and encouraged intensive production on a wide scale. Tree lines are cleared and wet areas drained, turning 120-acre farms into ...

How a new way of thinking about soil sparked a national movement in agriculture
For three weeks every month, Ray Archuleta captivates audiences with a few handfuls of soil. He begins with two clumps, dropping them into water. The soil from a farm where the soil isn’t tilled holds together, while the tilled soil immediately disperses, indicating poor soil structure. Next, volunteers from the audience — mostly farmers and ranchers — pour water over a soil ...
