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 during the soil conservation. One program, conservation comtransition to dryland crop production on the Texas pliance, requires a conservationplan tobe developed Southern High Plains. Three farm-program particiby 1990 and implemented by 1995 for producers to pation options were considered in this study. Particireceive farm program benefits. In some cases, a soil pation in an extension of the current farm program conserving plan may not be as profitable in the short resulted in an increase in net returns and wind eroterm as traditional cropping practices.

Residue management and tillage effects on soil-water storage and grain yield of dryland wheat and sorghum for a clay loam in Texas

Dryland wheat (Triticum aestivum L.) and grain sorghum (Sorghum bicolor (L.) Moench) are often grown using a wheat–sorghum-fallow (WSF) crop rotation on the semiarid North American Great Plains. Precipitation stored during fallow as soil water is crucial to the success of the WSF rotation. Stubble mulch-tillage (SM) and no-tillage (NT) residue management practices reduce evaporation, but the sp...

No-till Grain Production in Wyoming: Status and Potential

In dryland cropping systems, optimal yields require that nutrient supply matches the soil’s yield potential supported by available moisture. Conservation tillage systems that leave at least 30 percent of the soil surface covered by residue dramatically increase moisture retained in the soil compared to crop-fallow systems. This enables producers to plant two, three, or four consecutive crops, o...

Conservation tillage and water availability for wheat in the dryland of central chile

The dryland areas of Central Chile are associated to Mediterranean climate. Under these conditions, water availability during crop growth is a crucial factor for crop productivity. Conservation tillage systems play an important role in this area, increasing soil water availability; however, crop yield responses can be variable. Soil management should be aimed at reducing water loss and promotin...

Soil Functional Zone Management: A Vehicle for Enhancing Production and Soil Ecosystem Services in Row-Crop Agroecosystems

There is increasing global demand for food, bioenergy feedstocks and a wide variety of bio-based products. In response, agriculture has advanced production, but is increasingly depleting soil regulating and supporting ecosystem services. New production systems have emerged, such as no-tillage, that can enhance soil services but may limit yields. Moving forward, agricultural systems must reduce ...

Acreage allocation in the presence of various commodity and conservation programs: The case of conservation reserve program and crop production in the Midwest

A multinomial fractional logit model is developed in this article to examine the effects of various market variables, commodity and conservation program payments and county physical attributes on crop acreage allocation and CRP enrollment simultaneously in the Midwest region of the United States. Nine states and eleven years county level panel data are employed to estimate the acreage allocatio...
