Fostering and maintaining soil health via holistic management is a central goal for most organic farmers. However, many questions remain regarding how different practices influence in farm fields. In this study, we used mail-in survey to assess such as crop diversity, perennials rotation, tillage, manure use, subscription cation balancing biochemical indicators certified corn (Zea mays L.) Orga...

Compared with a monoculture planting mode, the practice of crop rotations improves fertilizer efficiency and increases yield. Large-scale rotation monitoring relies on results classification using remote sensing technology. However, limited accuracy cannot satisfy accurate identification patterns. In this paper, mapping scheme combining random forest (RF) algorithm new statistical features extr...

Effects of crop rotation on soybean (Glycine max (L) Merr.) seed composition have not been well investigated. Therefore, the objective of this study was to investigate the effects of soybean-corn (Zea mays L.) rotations on seed protein, oil, and fatty acids composition on soybean. Soybeans were grown at Stoneville, MS, from 2005 to 2008 in five different scheduled cropping sequences. In 2007, f...

Alfalfa (Medicago sativa L.) and corn (Zea mays are common forage plants for feeding livestock, their effects on soil bacterial organisms have been extensively studied. However, there is little comprehensive research function in a long-term alfalfa monocropping system after insertion fertilization. The of alfalfa–corn rotation (AF: monocropping, RA: rotation) nitrogen fertilization (RA0 RA15) w...

Subsurface drainage is a beneficial water management practice in poorly drained soils but may also contribute substantial nitrate N loads to surface waters. This paper summarizes results from a 15-yr drainage study in Indiana that includes three drain spacings (5, 10, and 20 m) managed for 10 yr with chisel tillage in monoculture corn (Zea mays L.) and currently managed under a no-till corn-soy...

Aspergillus flavus, the causal agent of aflatoxin contamination, is a natural inhabitant of soils. A. flavus can be divided into two strains, S and L, with S strain isolates having a greater aflatoxin contamination potential than L strain isolates. Aflatoxin contamination can be severe in several crops in South Texas including cottonseed and corn. A. flavus communities in soils of South Texas c...

The effects of nematicide treatments and corn-peanut cropping sequences on the population development of Criconemella ornata, and C. sphaerocephala and the related impact on crop yields were investigated at two North Carolina locations. Criconemella ornata and C. sphaerocephala were present at the Norman Perry farm, Bertie County (BERTIE); however, only C. ornata was found at the Central Crops ...

This study was designed to evaluate the improved version of the Root Zone Water Quality Model (RZWQM) using 6 yr (1992-1997) of field-measured data from a field within Walnut Creek watershed located in central Iowa. Measured data included subsurface drainage flows, NO3-N concentrations and loads in subsurface drainage water, and corn (Zea mays L.) and soybean [Glycine mar (L.) Merr.] yields. Th...

Seed-based pest management tools, such as transgenes and seed treatments, are emerging as viable alternatives to conventional insecticide applications in numerous crops, and often occur as coupled technologies. Seed-based technologies have been readily adopted in maize, for which ecological studies are needed to examine effects to farmland biodiversity. We compared the response of nontarget col...
