The role of conservation soil management on soil and water protection at different spatial scales [PDF]
, 2006 Agriculture has a direct impact on the soil environment, altering soil properties, surface characteristics and erosion risk. This has led to a move away from conventional tillage to the adoption of conservation practices, aiming to minimise soil ...

Nutrient distribution and relationship with soil properties in different watersheds of Haryana
The Indian Journal of Agricultural Sciences, 2020 Nutrient distribution in profile depths is unclear due to large exploitation of nutrient in the top soil while neglecting sub soil, which is also important from crop production point of view.

Association of Organic Carbon With Reactive Iron Oxides Driven by Soil pH at the Global Scale
Global Biogeochemical Cycles, 2022 Association of organic carbon (C) with iron (Fe) minerals is one important mechanism for long‐term terrestrial C storage. Yet, specific edaphic variables that directly contribute to Fe‐associated C across diverse soil types are still unclear.

Nature, 1971 THE purpose of this note is to call attention to the fact that usual methods of measuring soil pH1 seriously underestimate the pH of very acid soils, such as those of coal mine spoils2, cat clays3 and solfataras4, in which acidity is due to the presence of free sulphuric acid. Standard methods for measuring soil pH involve making a slurry of soil with (

BMC Microbiology, 2022 Soil microbes exist throughout the soil profile and those inhabiting topsoil (0–20 cm) are believed to play a key role in nutrients cycling. However, the majority of the soil microbiology studies have exclusively focused on the distribution of soil ...
