Wind drift is a very critical issue in pesticide applications. In recent experiments, the application of pesticides is focus on precision farming. In this study, a spraying system that could manipulate trajectories of droplets to decrease drift was tested in a wind tunnel. Three nozzles (XR11002, AIXR11002 and TTJ6011002) were used at three operating pressures (200 kPa, 300 kPa, 400 kPa), with four orientation angles of nozzles against wind direction (0°, 5°, 10°, 15°), and three wind velocities (1.5, 2, and 2.5 m s-1) with three repetitions. A statistical factorial CRD was used with Tukey Post Hoc Test …

Soil moisture sensors (SMSs) are a useful tool that aid in data-driven water management decisions. However, default factory calibrations can be inaccurate and soil-specific calibrations are often required to obtain higher accuracy in the determination of soil water storage and plant available water. In this study, we conducted a lab calibration for the Field Scout TDR 300, which is a popular SMS used in the turfgrass industry. Five soils of different soil textural classes were packed in containers with known soil moisture for the laboratory calibration. The logarithmic model best fit the data for the course- and fine-textured soils, with …

Uniformity of plant spacing and emergence have been shown to be significant contributing factors to increasing corn yields. Improved seed meters that offer very precise seed drop have been available on planters for a number of years. However, uniformity in plant emergence continues to be a challenge, especially with reduction of tillage and in fields with variable soils. Correct, consistent depth is critical for uniform corn emergence. By keeping the gauge wheels on the ground, consistent depth is achieved. An active downforce system, such as Precision Planting’s DeltaForce, applies hydraulic downforce or lift to the row unit. With a Precision …

Sprayable biopolymer membranes (SBM) is an emerging mulching alternative to increase horticultural and agricultural productivity by reducing soil erosion and evaporative losses. The SBM is usually applied in liquid form directly to the soil surface where the polymer molecules form a thin biodegradable film. In order to test this technology, an experiment was performed in greenhouse conditions with the goal of quantifying the impact on soil evaporation rate and biomass accumulation in winter wheat.
