As urbanization accelerates and arable land diminishes, indoor farming has emerged as a cornerstone of sustainable agriculture. Among its most transformative innovations is the vertical grow rack—a space-efficient system that stacks crops vertically to maximize yield in limited spaces. But designing an effective vertical grow rack setup isn’t as simple as stacking trays and plugging in…

Weedy rice populations across the globe offer support for many of these hypotheses
Our study aligns with these studies in recommending active long-term management to enhance native populations and resist invasive populations. Instead of viewing restoration projects primarily as short term implementation efforts with only an auxiliary “maintenance phase,” the implementation phase of restoration could be primarily focused on establishing the biophysical conditions needed for native plant species establishment…
Concentration of prey can result in increased strike success and reduced search time for fish
We collected four random samples of water hyacinth and associated invertebrates per site using a custom-built ¼-m2 quadrat with a 200-µm mesh pouch . For each sampling event, we scooped the sampler into the water column beneath the water hyacinth mat then brought the sampler upward, through the mat. This approach allowed us to sample…
Fire was the earliest form of brush and weed control in California’s annual rangelands
Brush control is one of the oldest and quickest ways to increase carrying capacity for livestock production, but the economics of this and other range improvement practices have changed. Before the energy crisis of the 1970s, it was less costly to use fossil fuels and fertilizers that are fossil fuel based in range improvement. Following…
No permit was required from the above authority as our study involved no treatment on animal daily cares
Sulfosulfuron is registered in California under the trade name Outrider for non-crop use. Imazapic is not currently registered in California and faces a difficult registration pathway in California, so future research will focus on another imidazolinone herbicide, imazamox, which has a more favorable registration pathway. Crop safety studies will need to be repeated using chemigated…
Field trials to study winter weed control in established alfalfa were also conducted at the same locations
Although scientists at Monsanto and Forage Genetics International have developed the technology, RR alfalfa varieties will be marketed broadly by a wide range of seed companies. Important characteristics, such as genetic resistance to insects and diseases and yield potential, remain important criteria for selecting a variety. The RR trait enables a unique weed control program…
The germination and emergence of weeds in rice fields vary with soil depth and water regime
Decades of this practice with little to no crop rotation, however, have selected for populations of grass species that can escape flooding, among them early watergrass [Echinochloa oryzoides Fritsch], late watergrass [E. oryzicola Vasinger] and bearded sprangletop [Leptochloa fusca Kunth ssp. fascicularis N. Snow] . In addition, season long flooding favors aquatic weeds and promotes the early season growth of algae.…
The majority of glufosinate residues found in almond samples were in the form of the metabolite MPP
An initial field study conducted in 2020 by Martin and Hanson revealed that very low levels of herbicide can transfer to almonds during harvest operations, and those residues appear to be primarily due to herbicide-bound to soil particles. The European markets are integral to the economic success of the California almond industry; however, glyphosate and glufosinate…
There were no detections of glyphosate or its metabolites in any of the almond kernel samples
The rinsate was collected into glass scintillation vials and evaporated to near dryness using vacuum evaporation. 10 mL of Ultima Gold™ was added to the scintillation vial and analyzed using the liquid scintillation counter. The rinsed kernels were homogenized and combusted; the combustion product was mixed with scintillant and analyzed using the liquid scintillation counter.To…
Leave the bottom of the hole undisturbed to help prevent the tree from settling below its root crown
With proper irrigation management, however, fruit trees can be grown in as little as 1 to 11 ⁄2 feet of good topsoil. An additional complication in many areas is the presence of an impervious layer of hardpan or claypan beneath the soil surface. Where hardpan is found within 11 ⁄2 to 2 feet of the surface, it…
