Scientists have found that adding biochar to farm soils can help steady the release of carbon dioxide during increasingly erratic rain and drought cycles, potentially supporting climate friendly ...

Lavender (Lavandula angustifolia) is relatively easy to grow, and who doesn't want to grow it? It's hard to beat those vibrant purple flowers on slender stalks with their heavenly aroma and variety of ...

A new study published in Biochar reveals that alkaline biochar, a type of carbon-rich soil amendment, significantly improves microbial carbon use efficiency and nutrient cycling in saline-alkali soils ...

Wood ash, left behind in the fireplace or after a bonfire, is often overlooked as a natural fertilizer. However, it's actually an invaluable tool for enriching soil, boosting plant health, and ...

Introduction: Fertilization is vital for improving grape (Vitis vinifera L.) yield and quality. Unlike traditional nitrogen fertilizers, the mechanisms by which sludge alkaline hydrolysate (SAH), a ...

To grow, plants must absorb nutrients from the soil. Not only must these nutrients be present in sufficient quantities, they must also be available for uptake by the plant. Nutrient availability is ...

If and when a Cascadia Subduction Zone earthquake hits the Portland region, soil liquefaction could dramatically worsen the damage, leading buildings to tilt, roads to buckle and utility lines to ...

Last week, a plot of land in North Portland felt a shake, but not one caused by an earthquake, but instead by a machine known as T-Rex. Researchers with Portland State University were simulating a ...

There are some misconceptions surrounding how we deal with soil when gardening, and I thought I’d discuss a few in this week’s column: to add, or not to use, gypsum; dealing with dense clay; and ...

Growing plants that are well-suited to your soil pH makes gardening a whole lot easier. While plants like potatoes flourish in acidic gardens, most veggies prefer slightly acidic to neutral soils, ...

ABSTRACT: This study investigated the effect of phosphorus chemical solid wastes (phosphogypsum and phosphorus tailings) modified land-making soil on corn quality and its safety evaluation. The ...
