Two Proofs and One Algorithm Related to the Analytic Hierarchy Process
36 years ago, Thomas Saaty introduced a new mathematical methodology, called Analytic Hierarchy Process (AHP), regarding the decision-making processes. The methodology was widely applied by Saaty and by other authors in the different human activity areas,

How do soil threats vary by climate? Can we mitigate soil threats with soil management practices? ABSTRACT Climate change, population growth, and intensifying land use are exerting increasing pressure on soil resources worldwide. Despite growing knowledge of soil degradation processes, the relationship between soil threats and the effectiveness of ...

Summary Many agroecosystems face nitrogen (N), phosphorus (P) or potassium (K) deficiencies due to imbalanced or insufficient nutrient replenishment after biomass harvest. How this affects the symbiosis between plants and arbuscular mycorrhizal fungi (AMF) and the abundance of exploration‐based AMF guilds (rhizophilic, edaphophilic and ancestral ...

Novel roles of sulfur metabolism in stress‐controlled stomata aperture regulation
Summary Stomatal closure allows plants to conserve water by reducing transpiration during drought. Surprisingly, the assimilation of the macronutrient sulfur is intimately connected to the drought stress response. This Tansley insight will only briefly touch on the general impact of sulfate assimilation on the production of drought‐response metabolites.

To moo or to mow: Disentangling the effects of management on Gladiolus imbricatus in coastal meadows
The rare grassland species Gladiolus imbricatus prefers mowing and mulching over grazing. Species' life stages provide a valuable indicator for its' abundance. Mowing date and grazing intensity are important factors in selecting a management in grassland restoration.

ABSTRACT Neolithic long barrows are among the earliest monumental structures in Europe, yet in many parts of Central Europe their surface expression has been largely erased by long‐term agricultural activity. This study evaluates the potential of integrated remote sensing approaches for identifying and contextualizing long barrows and associated ...

The mulch dilemma: Trade‐offs between soil water conservation and microirrigation water retention
Abstract Mulching is widely used worldwide to reduce soil water evaporation, but it can also intercept and retain rain or irrigation water, limiting infiltration into the soil and thereby altering the soil water balance. Microsprinkler irrigation in dwarf coconut orchards applies water in small, frequent doses, producing shallow, near‐surface wetting ...

Higher cutting frequency can restore semi‐natural habitat quality on farmland
Rather than productivity per se, the cover of dominant plant species drives plant species richness. Breaking the dominance of these species through defoliation can restore the species richness of the vegetation. Because dominant plant species can tolerate more defoliations at higher productivity, the number of times a vegetation needs to be cut to ...
