Assessing Nitrogen Credits From Clover Cover Crops And Effects Of Seed Inoculation, Ajay Nair, Kathleen Delate, Georgeanne Artz, Corene Bregendahl

Iowa State Research Farm Progress Reports

A wide array of information is available on cover crop selection, planting date, and potential advantages, but very little data is available on cover crop performance under Iowa growing conditions. In order to expand cover crop options for Iowa growers, more precise and region-specific information is needed.


Organic Vs. Conventional Farming Systems, Michael D. Duffy, Kenneth T. Pecinovsky Jan 2009

Organic Vs. Conventional Farming Systems, Michael D. Duffy, Kenneth T. Pecinovsky

Iowa State Research Farm Progress Reports

Driven by a consumer demand-driven market, interest in organic crop production continues to grow. A study was begun in 1977 to compare organic and conventional farming systems and was modified in 1999. Results from this study have previously been reported in the 1998 Annual Report (ISRF98-13) and the 2005 Annual Report (ISRF05-13).

Iowa State Research Farm Progress Reports

Organic agriculture has become a major industry in the last decade, driven by increasing consumer demand, price premiums, and improving market opportunities. In 1977, a study was started at the Northeast Research and Demonstration Farm to demonstrate two alternative farming systems.


The Economics Of Finishing Pigs In Hoop Structures And Confinement Facilities: A Summer Comparison, Benjamin Larson, James B. Kliebenstein, Mark S. Honeyman, Arlie D. Penner Jan 2002

The Economics Of Finishing Pigs In Hoop Structures And Confinement Facilities: A Summer Comparison, Benjamin Larson, James B. Kliebenstein, Mark S. Honeyman, Arlie D. Penner

Iowa State Research Farm Progress Reports

This report is part of an ongoing research project that is being conducted at the Iowa State University Rhodes Research Farm. This research is aimed at comparing two swine finishing facility types under a wide range of circumstances. This report provides results from a group of pigs finished during the summer season of 2000–2001. Evolution of the swine industry has forced industry members to reevaluate operations and utilize an increasing amount of risk management. A survey conducted in May 2001 showed that hoop buildings are becoming an important part of the swine industry. Hoop buildings became widely available in ...

An Analysis Of The Cost Of Producing Pork In Hoop Structures And Confinement During The Summer, Benjamin Larson, James B. Kliebenstein, Mark S. Honeyman, Arlie D. Penner Jan 2001

An Analysis Of The Cost Of Producing Pork In Hoop Structures And Confinement During The Summer, Benjamin Larson, James B. Kliebenstein, Mark S. Honeyman, Arlie D. Penner

Iowa State Research Farm Progress Reports

This research compares pork production in two types of production facilities. Information for the fourth group of pigs, which was fed from June 1999 to October 1999 at the Rhodes Research and Demonstration Farm, is provided. Results will be evaluated using the actual production efficiency numbers and the average or typical costs for feeder pigs, feed, etc., along with average market hog prices. This allows for comparison of expected costs and returns for normal input cost and hog price conditions.

An Analysis Of The Cost Of Producing Pork In Hoop Structures And Confinement During The Winter, Benjamin Larson, James B. Kliebenstein, Mark S. Honeyman, Arlie D. Penner

Iowa State Research Farm Progress Reports

This research is aimed at comparing two types of facilities for pork production--hoops and confinement systems. This report provides results from a group of pigs finished during the winter season. Hogs were on test from December to April. Results are evaluated by using the actual production efficiency values and the average or typical costs for feeder pigs, feed, etc., along with average market hog prices. This allows for comparison of expected costs and returns for normal input costs and hog price conditions.
