The no-tillage system is perceived as having lower soil temperatures, wetter soil conditions, and greater surface penetration resistance compared with conventional and other conservation tillage systems. Concerns associated with the effect of the no-tillage system on certain soil physical properties (i.e. soil temperature, moisture, and compaction) prompted this study to evaluate the effect of ...

This letter presents a LiDAR odometry estimation framework called Generalized LOAM. Our proposed method is generalized in that it can seamlessly fuse various local geometric shapes around points to improve the position accuracy compared conventional and mapping (LOAM) method. To utilize continuous features for estimation, we incorporate tiny neural networks into iterative closest point (GICP) a...

The most important biotic stress factor impacting tomato crop biophysical, biochemical, physiological, and morphological features is water stress. A pot experiment was undertaken in a greenhouse to study the drought responsiveness of (Solanum lycopersicum) yield quality indices sandy loam silty soils. For both soils, supply levels were 70–100% FC, 60–70% 50–60% 40–50% FC ETo (crop evapotranspir...

The photolytic degradations of imidacloprid, carbofuran, diazinon, chlorpyrifos, pyridaben, propoxur, and esfenvalerate were independently compared in both moist (75% field moisture capacity at 0.33 bar) and air-dry microbially viable soils at 5 microg/g. All compounds were applied to sandy soil except for propoxur, which was applied to sandy loam soil. Diazinon was applied to both sandy soil a...

Semi-arid regions faced with increasingly scarce freshwater resources must manage competing demands in the food-energy-water nexus. A possible solution modifies soil hydrologic properties using biosurfactants to reduce evaporation and improve water retention. In this study, two different textures representative of agricultural soils Kansas were treated a direct application biosurfactant, Surfac...

The high-yield varieties ‘Banks’ and ‘Cybonnet’, released to seed growers during 2004, contain the Pi-ta R gene used in blast-resistant varieties for over 16 years. While Cybonnet fields were blast free, severe blast disease developed in drought-stressed Banks growing in a sandy production field in Clay County during 2004 and then again in sandy fields throughout Arkansas during 2005 and 2006. ...

Rapid deforestation in Sumatra, Indonesia is presently occurring due to the expansion of palm oil and rubber production, fueled by an increasing global demand. Our study aimed to assess changes in soil-N cycling rates with conversion of forest to oil palm (Elaeis guineensis) and rubber (Hevea brasiliensis) plantations. In Jambi Province, Sumatra, Indonesia, we selected two soil landscapes - loa...
