Increasing atmospheric CO2 concentration has led to concerns about potential effects on production agriculture as well as agriculture’s role in sequestering C. In the fall of 1997, a study was initiated to compare the response of two crop management systems (conventional and conservation) to elevated CO2. The study used a split-plot design replicated three times with two management systems as m...

A model was developed for estimating average annual soil loss by water on hillslope for cropland, which is called Chines Soil Loss Equation (CSLE). Six factors causing soil loss were evaluated based on soil loss data collected from experiment stations covering most regions of China and modified to the scale of Chinese unit plot defined. The model uses an empirical multiplicative equation, A=RKL...

irrigation levels decline and dryland acreage inPredicted crop yields and wind erosion rates from creases, the incidence of wind erosion is expected to a multi-year/multi-crop growth simulation model increase. For the Texas High Plains, this is occurring provided input into a multi-period recursive QP at a time when farm policy is emphasizing long-term model to evaluate erosion implications dur...

The ability to inventory and map soil salinity at regional scales remains a significant challenge to scientists concerned with the salinization of agricultural soils throughout the world. Previous attempts to use satellite or aerial imagery to assess soil salinity have found limited success in part because of the inability of methods to isolate the effects of soil salinity on vegetative growth ...

It is widely believed that soil disturbance by tillage was a primary cause of the historical loss of soil organic carbon (SOC) in North America, and that substantial SOC sequestration can be accomplished by changing from conventional plowing to less intensive methods known as conservation tillage. This is based on experiments where changes in carbon storage have been estimated through soil samp...

Despite weeds are a serious threat to promotion of organic farming, relatively less attention is given to research on weed management. This article explores a scope of integration of conservation agriculture for weed control and soil protection under organic farming. Limitation in the use of agro-chemicals under OF promotes intensive tillage for weed control. Mostly, tillage leads to depletion ...

different conservation tillage practices are nowadays suggested as the best solution for prevention of soil from erosion. this could be done by leaving the previous crop residue on the soil surface. a new idea to plant in the conservation tillage system is the use of punch planters by which one can plant through a heavy depth of previous crop surface residue. the study was conducted using a 2?3...

rangelands are the main sources of forage for livestock feeding by localpeople. beside forage production, rangeland ecosystems provide many other goods andservices such as medicinal plants, recreation, soil and water conservation, wildlife habitat,fishing, hunting, hiking, etc. nevertheless, there are no much information about the waythat local communities think about the rangelands goods and s...
