The water bottle pocket folds out from a hidden compartment in the back and is the perfect size for an average plastic water bottle (16.9 fl oz), so if you love to stomp around town with a giant ...
Pores (the spaces that exist between soil particles) provide for the passage and/or retention of gasses and moisture within the soil profile.The soil's ability to retain water is strongly related to particle size; water molecules hold more tightly to the fine particles of a clay soil than to coarser particles of a sandy soil, so clays generally retain more water.

Zinc fluxes between the lithosphere and biosphere, through basins in soil, biomass, water systems, and industry. [1] Estimated fluxes are shown as labeled arrows in Gg/year. The zinc cycle is a biogeochemical cycle that transports zinc through the lithosphere , hydrosphere , and biosphere .
Synthetic polymers began replacing other chemical binders for soil stabilization in agriculture in the late 20th century. [1] Compared to traditional chemical binders, polymer soil additives can achieve the same amount of strengthening at much lower concentrations – for example, mixtures of 0.5-1% of various biopolymers have strength levels that match or exceed those of 10% cement mixtures ...
“The thing about water bottles is that, like all beverage containers, they come into contact with our mouth and hands—which are home to a lot of germs,” says Professor Stephanie Liberatore ...
Like many people, Carl Behnke regularly totes a water bottle around throughout his day to make sure he stays hydrated.From the office to the gym and back home again, Behnke is rarely without it.
Maize plants with severe zinc deficiency in the foreground, with healthier plants (planted at the same time) in the background. Zinc deficiency is common in many different types of soil; some soils (sandy soils, histosols and soils developed from highly weathered parent material) have low total zinc concentrations, and others have low plant-available zinc due to strong zinc sorption ...
Lawns get treated with up to 10 times more synthetic chemicals per acre than farms. Homeowners' use of pesticides and fertilizers is hurting a burning planet.
