WINTER WHEAT PRODUCTIVITY IN DEPENDENCE ON THE METHODS OF PRIMARY TILLAGE IN THE NIZHNEE POVOLZHIE
The result of the study was an establishment of dependence of winter wheat productivity on a method of a primary tillage. There has been identified an advantage of deep chiseling on 0.35–0.37 m over moldboard plowing on 0.20–0.22 m, over disk tillage on ...

A Concept of the Effective Surface Profile to Predict the Roughness Parameters of Worn Surface
A new concept of the effective surface profile is proposed to facilitate the prediction of the worn surface texture at sliding friction. The effective surface profile is a 2D height characteristic that consists of the asperities of surface superimposed ...

Abstract Greenhouse gas emissions from crop production contribute to anthropogenic climate change, while agricultural soils also sequester atmospheric carbon. Direct measurement of soil organic carbon (SOC) is limited by high sampling costs and the vast spatial extent of farmland.

The German Soil Systematics and the Rationale Behind Its Revision
ABSTRACT Background The German Soil Systematics is a pedogenetic classification based on the morphological expressions of pedogenic processes and has been developed over several stages since 1952. The system has successfully been in use for soil classification and soil survey for almost 70 years.

Food Security Versus Environmental Health: The Nitrogen Dilemma
ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.
