The Combined Effects of Water Management and Biochar Amendment on Soil Water Content and pH of Paddy Soil

Guan'gai paishui xuebao, 2021
【Background】 Traditional rice production in paddy fields in subtropical regions in China is to keep the soil surface flooded. This is not only a waste of water resources but also acidifies the soil and leaks agrochemicals to water bodies. Improving water

The pH optimum of soil exoenzymes adapt to long term changes in soil pH [PDF]

Soil Biology and Biochemistry, 2019
Soil exoenzymes released by microorganisms break down organic matter and are crucial in regulating C, N and P cycling. Soil pH is known to influence enzyme activity, and is also a strong driver of microbial community composition; but little is known about how alterations in soil pH affect enzymatic activity and how this is mediated by microbial ...

Automation of Orchid Soil pH Using IoT-Based Soil pH Sensor (SKJ-001)

Journal of the Physical Society of Indonesia
The growth and development process of cymbidium orchids requires a soil pH of around 5.5–6.5. Otherwise, it will cause low nutrient absorption, resulting in yellow leaves and slow growth, while too high a pH can cause the plant's roots to die. Therefore,

Comparisons of the effects of different drying methods on soil nitrogen fractions: Insights into emissions of reactive nitrogen gases (HONO and NO)

Atmospheric and Oceanic Science Letters, 2020
Reactive nitrogen (Nr) emission from soils, e.g., nitrous acid (HONO) and nitric oxide (NO), is a key process of the global nitrogen (N) cycle and has significant implications for atmospheric chemistry.
