A Systemic Model for Understanding Business Interactions With Biodiversity and Ecosystems

Business Strategy and the Environment, EarlyView.
ABSTRACT Biodiversity loss and ecosystem degradation represent critical threats to human well‐being and economic resilience, challenging businesses to understand and manage their interdependence with natural systems. This study develops a systemic framework—the BioModel—that elucidates the reciprocal relationship between businesses, biodiversity, and ...

Demanda energética na subsolagem realizada antes e depois de diferentes sistemas de preparo periódico do solo Energy demand in the subsoiling performed before and after different systems of periodic soil tillage

Ciência Rural, 2009
A subsolagem é uma das operações mecanizadas de elevado custo e demanda energética por área, tradicionalmente utilizada pelos agricultores antes do preparo do solo na descompactação de camadas adensadas. Este trabalho teve como objetivo avaliar a demanda

Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Exploring variations in potential carbon and nitrogen mineralization in managed grasslands among the diversity of soils in North Carolina

Grassland Research, EarlyView.
Under steady–state conditions, potential nitrogen mineralization in soil under grasslands is closely tied to potential carbon mineralization. This study provides supporting evidence that field–specific nitrogen fertilizer recommendations could be indicated by using a simple and rapid analysis of soil–test biological activity.

Effects of no-tillage and subsoil loosening on soil physical properties and crop performance : a thesis presented in partial fulfilment of the requirements for the degree of Master of Applied Science in Soil Science at Massey University [PDF]

, 1998
Much of New Zealand's lowland agriculture integrates animal and crop production on poorly drained, easily compacted soils. Over the years, conventional cultivation has given rise to degraded soil structure on many farms.

Boron availability and fertilizer response of maize in soils from sub‐Saharan Africa

Journal of Plant Nutrition and Soil Science, EarlyView.
Abstract Background and aims Low boron (B) availability is associated with strongly weathered, coarse‐textured, and low organic matter soils, widespread in sub‐Saharan Africa (SSA). It is unknown to what extent B fertilization can increase maize yields in SSA.

Perennial Legumes Pueraria phaseoloides and Leucaena leucocephala Exhibit High Potential for Fertility Restoration of Degraded Mined Soils in Ghana

Journal of Plant Nutrition and Soil Science, EarlyView.
Revegetating the subsoil layer of abandoned gold mined sites with the perennial legumes Leucaena Leucocephala, Pueraria phaseoloides and Gliricidia sepium without any soil amendments increases the content of soil organic carbon and important macro‐nutrients, which are crucial for restoring soil health and productivity. These improvements in soil health

Новый подход к выбору способа механической обработки грунта в условиях юга Украины [PDF]

, 2016
At a choice of an optimum way of machining of soil each land owner pursues one main aim - creation an optimum arable layer for cultivation of crops. Cultivation of soil finds the display in three systems: moldboard tillage, moldboardless tillage and no-
