2021-2-20 · Background and aim Plant pathogenic and mycotoxin-producing Fusarium species are globally widespread and lead to large annual yield losses in maize production (ecosystem disservice). Systems with reduced tillage and mulching are particularly under threat. In the present study, the bioregulatory performance (ecosystem service) of the common earthworm species …
High plant density is considered a proficient approach to increase maize production in countries with limited agricultural land; however, this creates a high risk of stem lodging and kernel abortion by reducing the ratio of biomass to the development of the stem and ear. Stem lodging and kernel abortion are major constraints in maize yield production for high plant density cropping; …
2021-2-9 · Changes in the size of a crop while growing are frequently used to determine the time of harvest. For example, partially mature cobs of Zea mays saccharata are marketed as sweet corn, while even less mature and thus smaller cobs are marketed as baby corn. For bananas, the width of individual fingers can be used to determine harvest maturity.

This concept is fairly new in the uk but has been on equipment in Scandinavia for the last 25+ years. The Tiltrotator make machinery 30-40% more efficient especially when operaiting from bog mats meaning more can be achieved from the one location and not having to move the machine around to reach the difficult areas just out side the working range of a standard machine.
We considered two contrasting soil structure scenarios: soil with the structure kept intact and soil for which the structure was destroyed via sieving. For the experiment, soil was collected from 0–15 cm depth at a 20-year continuous maize (Zea mays L., C4 plant) experiment into which cereal rye (Secale cereale L., C3 plant) was planted.
2021-10-5 · A drawback of using field soil, however, might be its variable quality, as the soil could contain weeds and pests, and might have poor aeration, especially when soil structure is lost during preparation (Douglass et al., 2009; Landis et al., 2014). To mitigate the latter problem, some researchers have used intact soil cores for growing plants.

The growth of castor plants was reduced in a soil with 6.5 mmol c cm −3 of Al, but the addition of wood ash or bovine manure reduced the effect of acidity (Lima et al., 2009b). Increased exchangeable Al content was also less harmful to the growth of castor plants when the soil had a high content of organic matter (Lima et al., 2007a).
2017-12-21 · The avian beak is a highly evolvable structure. The malleability of beak morphology permits birds to adapt, sometimes rapidly, to diverse ecological niches [].Various interrelated ecological and behavioral aspects of diet and feeding, such as local and seasonal food availability, dietary preference, and acquisition and manipulation of food and water (e.g., food …
2020-3-12 · The soil, derived from a fluviolacustrine deposit plain, has a loam texture, with 0.10 kg sand/kg soil, 0.9.15 kg silt/kg soil, and 0.45 kg clay/kg soil. Immediately after wheat (Triticum aestivum L.) or maize (Zea mays L.) harvest, all the surface crop straw was crushed by mechanical equipment and then return to the field for all treatments.

During oil and natural gas production, so-called "produced water" comprises the largest byproduct stream. In addition, many oil and gas operations are augmented via injection of hydraulic fracturing (HF) fluids into the formation. Both produced water and HF fluids may contain hundreds of individual chemicals, some known to be detrimental to public health and the environment.
