Soil

compaction is a form of physical degradation resulting in densification and distortion of the where biological activity, porosity and permeability are reduced, strength is increased and structure partly destroyed. Compaction can reduce water infiltration capacity and increase erosion risk by accelerating run-off.

1. Introduction. moisture (SM) is considered an essential climate variable (GCOS, 2010).It exerts control on the water and energy exchange between the and the atmosphere, as it behaves as a storage component for precipitation and induces persistence in the climate system (Martínez-Fernández et al., 2021; Piles et al., 2021; Seneviratne et al., 2010).

Abstract. Agricultural erosion is thought to perturb the global carbon cycle, but estimates of its effect range from a source of 1 petagram per year –1 to a sink of the same magnitude. By using caesium-137 and carbon inventory measurements from a large-scale survey, we found consistent evidence for an erosion-induced sink of atmospheric ...

Introduction. erosion is ‘the wearing away of the land surface by physical forces such as rainfall, flowing water, wind, ice, temperature change, gravity or other natural or anthropogenic agents that abrade, detach and remove or geological material from one point on the earth's surface to be deposited elsewhere’ ( Society of America, Citation 2001; Jones et al ...

It has proved a powerful tool in conveying best practice to lay audiences, and is increasingly found in international fora, strategic programmes (e.g. Health and Food Mission, the Health Institute, the Biology and Health Partnership, UK 25 Year Environment Plan), agreements and long term plans (Jian et al., 2020).

We found much variation between countries for each of the three steps: There are more than 10 -P tests currently in use, apparent contradictions in the interpretation of -P test values and more than 3-fold differences in the P fertilizer recommendations for similar -crop situations.

Zhijun Wei, Chenglin Li, Xiaofang Ma, Shutan Ma, Zongyang Han, Xiaoyuan Yan, Jun Shan. , e13428. First Published: 20 October 2023. Biochar promotes denitrification in acidic paddy by increasing pH and enhances the same process in alkaline paddy by increasing nosZ gene abundance, resulting in reduced N 2 O emissions. Abstract.

Here we conducted a global analysis of the bacterial communities found in surface soils from 237 locations across six continents and 18 countries (fig. S1) to (i) identify the most dominant (i.e., most abundant and ubiquitous) bacterial phylotypes worldwide; (ii) determine which of these dominant phylotypes tend to co-occur and share similar environmental preferences; (iii) map the ...
