Abstract:

Field experiments were carried out to evaluate the performance of laser guided land leveler for land leveling and grading operations to determine its effect on water requirements and yield of selected crops. Comparison was made with fields in which leveling! grading was done conventionally with drag scraper and also with unleveled fields. The standard deviation of reduced levels and leveling index values ranged from 0.43 to 0.50 cm and 0.29 to 0.34 cm respectively in case of fields leveled/ graded by laser guided land leveler. In case of conventional method, the standard deviation of reduced l

The cultivation relies on old land dams, lines, and furrow surface irrigation systems. A significant portion (76%) of the cultivated land is irrigated with high-density leveled soil instead of unlevelled soil. Leveled soil has very low clay and organic matter content. Land leveling is a preparation or modification process that provides a suitable surface for seeding production. It involves reducing high areas and raising low or deep spots to create a more even surface. La

In particular, scholars in this region have successively improved multiple paddy field levelers to realize excellent straw returning and subsequent land preparation synchronously, but the economic benefit from land preparation to crop harvest was less reported.

Abstract. The Taiwan Water Resources Agency uses four techniques to monitor subsidence in Taiwan, namely data from leveling, global positioning system (GPS), multi-level compaction monitoring wells (MCMWs), and interferometry synthetic aperture radar (InSAR). Each data type has advantages and disadvantages and is suitable for different analysis tools. Only MCMW data provide compaction information at different depths in an aquifer system, thus they are adopted in this study. However, the cost of MCMW is high and the number of MCMW is relatively low. Leveling data are thus also adopted due to it

Abstract:

Rice production in the Central Plains of Thailand plays a key role in the country’s food security. However, the overuse of inputs coupled with the rising production costs are making it increasingly difficult for smallholder rice farming to remain economically and environmentally sustainable. Replicated production-scale field trials of Cost Reduction Operating Principles (CROP)—Thailand’s national package of best management practices for rice production—were established in tandem with laser land leveling (LLL), mechanical drum seeder, and the application of two biofertilizer products (i.e., PGP

Abstract:

In the last years, the advanced synthetic aperture radar (SAR) interferometry (InSAR) has proven its effectiveness in the assessment of ground gotion with millimetric accuracy. Its integrated use with traditional (in-situ) topographic height determination techniques, such as geometric leveling and Global Navigation Satellite System (GNSS), is consolidated in underground fluids extraction areas for detecting and monitoring land subsidence. Nevertheless, the lack of a specific standardized methodology does not allow for evaluating different results obtained from different types of analysis. Star

Abstract:

This introduction on sweet corn includes a detailed account of its history, cultivation, and accompanying technologies. Sweet corn, a variety of field corn (Zea mays) with a genetic mutation that results in greater sugar content in its kernels, was initially grown in Pennsylvania in the mid-1700s, with commercial versions developing by 1779. The essay discusses the numerous current kinds of sweet corn, which range in sweetness, color, and genetic alterations for increased resistance to pests and herbicides. The production technique for sweet corn needs careful selection of land, especially in

Abstract:

Abstract This article examines the radial dependence of the height of the maximum wind speed in a hurricane, which is found to lower with increasing inertial stability (which in turn depends on increasing wind speed and decreasing radius) near the eyewall. The leveling off, or limiting value, of the marine drag coefficient in high winds is also examined. The drag coefficient, given similar wind speeds, is smaller for smaller-radii storms; enhanced sea spray by short or breaking waves is speculated as a cause. A fitting technique of dropsonde wind profiles is used to model the shape of the vert

Forty soil samples were collected at three depths (0–10, 10–20, and 20–30) cm from treated (Antisar) and control (Malkahana) watersheds. Results revealed significant variations (p < 0.05) in soil pH, SOC, and total N across land uses, with ALS showing the highest pH, SOC, and N content, followed by SLS and FLS. SOC and N decli
