Soil Quality Under Permanent And Annual Pastures: Its Implications For Soil Microbial Activity And Nutrient Turnover, R. J. Haynes, R. M. Milne, N. Miles
Soil Quality Under Permanent And Annual Pastures: Its Implications For Soil Microbial Activity And Nutrient Turnover, R. J. Haynes, R. M. Milne, N. Miles
IGC Proceedings (1997-2023)
Dairy farming in humid, subtropical parts of South Africa is based on permanent kikuyu grass (Pennisetum clandestinum) swards. However, there is a shortage of feed during the winter because low temperatures limit kikuyu growth. As a result, annual pastures incorporating temperate grasses, are grown for winter feed production. The grasses used are typically annual ryegrass (Lolium multiflorum) and sometimes perennial ryegrass (Lolium perenne). Kikuyu is so invasive in the locality that it becomes dominant within a few years, even if the field is sown to perennial ryegrass. For that reason, the swards are usually …

Effects Of Tree And Tillage Systems On The Productivity Of The Herbaceous Stratum In Silvopastoral Systems In The Southwest Of Córdoba, Argentina, O. Plevich, C. Saroff, C. Cholaky, T. Pereyra, O. Barotto, H. Pagliaricci
IGC Proceedings (1997-2023)
In the southwest of Córdoba, Argentina, there are lands with severe water erosion, due to the interaction of rolling pampas, high intensity precipitation, loam soil, and farming systems based on annual crops (Cantero et al., 1998). In an attempt to mitigate the erosive processes, a silvopastoral system was established in which winter forage was combined with trees. To improve the physical condition of the soil, two tillage systems were implemented. The objective of this paper was to determine the effect of trees and tillage systems on the production of forage.
Previous Grass-Lucerne Mixtures Affect Barley Yield And Quality In A Semiarid Location Of The Canadian Prairie Region, P. G. Jefferson, F. Selles, R. P. Zentner, R. Lemke
Previous Grass-Lucerne Mixtures Affect Barley Yield And Quality In A Semiarid Location Of The Canadian Prairie Region, P. G. Jefferson, F. Selles, R. P. Zentner, R. Lemke
IGC Proceedings (1997-2023)
In the semiarid region of the Canadian prairies perennial forages are not rotated with annual crops because previous experiments reported negative impacts (Kilcher and Anderson 1963; Campbell et al. 1990). However, previous research used persistent species while short-lived species could have less adverse effect. Our objective was to compare three grass species in three lucerne mixtures terminated with tillage or herbicide for effects on barley grain, N concentration, and N uptake.

The Impact Of Tillage System For Small-Grain Pasture Establishment On The Performance Of Growing Beef Calves In Arkansas, P. Beck, S. Gunter, M. Anders, K. Lusby, D. Hubbell
IGC Proceedings (1997-2023)
In the United States, governmental regulations mandate the improvement of farming practices to improve environmental quality. There is a requirement to reduce the siltation of waterways, soil carbon losses, and nutrient runoff along the Mississippi River Delta. The use of small-grain forages by grazing cattle offers real opportunities to produce high-quality forage for cattle production during the winter and spring months. No-till and reduced tillage practices developed primarily for grain production may offer environmental and economic solutions for both grain farmers and cattle producers. Producers are slow to adopt conservation tillage practices because of a perceived risk of reduced production. …
Tillage Study For Corn And Soybeans: Comparing Vertical, Deep, And No-Tillage / Year 10, E. Adee
Tillage Study For Corn And Soybeans: Comparing Vertical, Deep, And No-Tillage / Year 10, E. Adee
Kansas Agricultural Experiment Station Research Reports
Trends from a tillage study conducted since 2011 have shown no clear differences between tillage systems for either corn or soybeans in lighter soils under irrigation. One year out of eight years has shown a yield advantage for either corn or soybeans for any tillage system, which appears to be related to environmental conditions experienced during the season. Averaged across all years of the study, the treatments with deep tillage either every or every-other year had about 4.5% higher corn yields, and soybeans had up to a 3.2% yield increase with some form of tillage.

Department of Agronomy and Horticulture: Faculty Publications
Besides a proper agronomic management followed by Nepalese farmers, wheat (Triticum aestivum L.) production has been severely affected by changing climate. There are many interventions, including climate-smart practices, to cope with this situation and possibly enhance crop and soil productivity. Field experiments were set up in a randomized complete block design with six treatments (TRT) with four replications in three locations (LOC) during wheat-growing seasons in Nepal from 2014 to 2016. Treatments included (i) Controlled Practice (CP), (ii) Improved Low (IL), (iii) Improved High (IH), (iv) Climate Smart Agriculture Low (CSAL), (v) Climate Smart Agriculture Medium (CSAM), and (vi) …
Soil Health Assessment For The Agroecosystems Of West Tennessee, Surendra Singh
Soil Health Assessment For The Agroecosystems Of West Tennessee, Surendra Singh
Doctoral Dissertations
Soil health assessment is important for making informed sustainable management decisions in production systems. An established standardized method to quantify soil health is lacking and the validity of the existing methods across agroecoregions and cropping systems is not yet proven. Therefore, this study aims to evaluate the feasibility of widely discussed three soil health tests - Haney’s Soil Health Test (HSHT), Comprehensive Assessment of Soil Health (CASH), and Alabama Soil Health Index (ASHI) to assess soil health in diverse cropping systems of Tennessee. Since these approaches were originally developed for specific agroecoregions, we hypothesized that these tests are not sensitive …
Considerations For Crop Rotation From Alfalfa To Corn, Earl Creech, Matt Yost, Grant Cardon, Corey Ransom, Jason Clark
Considerations For Crop Rotation From Alfalfa To Corn, Earl Creech, Matt Yost, Grant Cardon, Corey Ransom, Jason Clark
All Current Publications
The importance of rotating out of a declining alfalfa stand is well established. As the alfalfa stand ages, forage yield and quality decline, while weed, insect, and disease pressures increase. Terminating the stand and growing one or more other crops for several (2–3) years allows a grower to press the reset button on a piece of ground. These years of growing another crop will result in more productive alfalfa when a new stand is planted again.

Nematode Populations As Affected By Residue And Water Management In A Long-Term Wheat-Soybean Double Crop In Eastern Arkansas, Lucia Emperatriz Escalante Ortiz
Graduate Theses and Dissertations
Soybeans (Glycine max) are one of the major row crops in the United States, particularly in Arkansas. Soybean cyst nematode (SCN, Heterodera glycines) and southern root-knot nematode (RKN, Meloidogyne incognita) are two of the most damaging pests that cause major economic losses in soybeans. Little is known concerning the effects of common and alternative agronomic practices on nematodes in fields with nematode population densities below threshold levels. Therefore, the objective of this study was to evaluate the effects of the combination of tillage (conventional tillage and no-tillage), irrigation (irrigated and non-irrigated), wheat (Triticum aestivum) residue burning (burned and no burned), …

Response Of Soybean Grown On A Claypan Soil In Southeastern Kansas To The Residual Of Different Plant Nutrient Sources And Tillage, D. W. Sweeney, P. Barnes, G. Pierzynski
Kansas Agricultural Experiment Station Research Reports
The residual from previous high-rate turkey litter applications, which were based on nitrogen (N) requirements of the previous grain sorghum crop, increased 2018 soybean yield more than that obtained from the residual of phosphorus (P)-based turkey litter applications (low rate), commercial fertilizer, or the control. Even though early soybean growth was sporadically affected by residual treatments, the dry matter production at the R6 growth stage tended to be where the N-based litter was applied.

Soil compaction is an important concern for surface mine operations that require heavy equipment for land reclamation. Excessive use of rubber-tired equipment, such as scraper pans, may cause mine soil compaction and hinder the success of revegetation efforts. However, information is limited on management strategies for ameliorating the potential compacting effects of scraper pans, particularly during site preparation for loblolly pine (Pinus taeda L.) plantations. Three forms of tillage and one control were replicated five times on surface mined land in the west Gulf Coastal Plain: no tillage (NT), disking (D), single-ripping + disking (R+D), and cross-ripping + disking …

Timing Of Side-Dress Applications Of Nitrogen For Corn In Conventional And No-Till Systems, D. W. Sweeney, D. E. Shoup, Dorivar Ruiz Diaz
Kansas Agricultural Experiment Station Research Reports
Environmental conditions vary widely in the spring in southeastern Kansas. As a result, much of the N applied prior to corn planting may be lost before the time of maximum plant N uptake. Side-dress or split applications to provide N during rapid growth periods may improve N use efficiency while reducing potential losses to the environment. The objective of this study was to determine the effect of timing of side-dress N fertilization compared with pre-plant N applications for corn grown on a claypan soil.
