New studies highlight how thiosulfates not only supply sulfur but also significantly reduce nitrogen loss by slowing the ...

Hydrangeas will stop withering and grow healthier if watered with one natural item every seven days, according to a gardening enthusiast.

In a restoration area of the park, the researchers analyzed the growth of invasive grasses and native species after applying iron sulfate, which makes the soil more acidic and reduces nutrient ...

Potential acid sulfate soils contain pyrite, which reacts with atmospheric oxygen to form sulfuric acid on exposure to air through drainage. It creates extreme acidity that causes the release of toxic ...

Sulfurization is a pedogenic process that involves pyrite oxidation and strong soil acidification, accounting for the formation of acid sulfate soils. In Antarctica, acid sulfate soils are related to ...

If you're wondering how to make garden soil acidic, end your info hunt here. We've rounded up the most effective methods, and some you should avoid.

Omnia's BME division has recently tackled a challenge at a South African iron ore mine, where a reduction in blasting efficiency prompted them to investigate a new mechanism for bulk emulsion ...

The team's extensive testing ruled out common culprits like reactive soil or acidic water, leading them to a surprising discovery: the presence of potential acidic sulphate soil (PASS).

BME experts confirmed that iron ore mines are generally not linked to reactive or acidic ground, based on ground sample reactivity tests.

“Actual acid sulphate soils (AASS) – soil materials that contain RIS – have undergone oxidation to produce acid; any pH drop indicates the soil’s potential to form sulphuric acid when it is disturbed ...

These acid sulphate soils can form in waterlogged areas devoid of oxygen and rich in organic matter. They contain crystals of pyrite – iron sulphide minerals. When they lie undisturbed, they are safe ...
