Climate change effects on biomass and greenhouse gas emissions are ameliorated by nontoxic endophytes in southeastern USA transition zone tall fescue pastures

Grassland Research, EarlyView.
Tall fescue produces more biomass and less carbon dioxide from the soil when it contains its beneficial fungal endophyte. Increased temperatures projected with climate change reduce fescue biomass, while altered rainfall frequency does not. Altering rainfall frequency and increasing temperatures can reduce carbon dioxide emissions from soil.

Effect of planting methods and tillage practices on soil health and maize productivity

Frontiers in Plant Science
IntroductionTo increase the crop yield, the amount of agrochemicals used in field has increased in recent years. Moreover, indiscriminate use of chemical fertilizers has led to soil deterioration and compaction.

Influence of notillage on carbon sequestration and erosion in Brazil [PDF]

, 2004
Les sols constituent le plus gros réservoir superficiel de C (hors les roches carbonatées), environ 1500 Gt C, ce qui équivaut à presque trois fois la quantité stockée dans la biomasse terrestre, et deux fois celle de l'atmosphère.

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.

Transforming Agricultural Water Management Through the Water–Energy–Food Nexus: Trends, Opportunities, Barriers and Solutions

Irrigation and Drainage, EarlyView.
ABSTRACT Agricultural water management (AWM) is increasingly transitioning towards transformative thinking, where interconnected sectors, including water, energy and food, are managed holistically. Trends point towards cross‐sectoral and harmonised strategies to optimise water use efficiency and productivity, integrate renewable energy, promote ...

Impact of Irrigation Scheduling on Corn Yield and Water Balance in Sandy Soils of Central Minnesota Using the EPIC Model.

Irrigation and Drainage, EarlyView.
ABSTRACT Efficient irrigation scheduling is critical in sandy soils to achieve optimum yield and maximum net benefit with minimum environmental concerns. The Environmental Policy Integrated Climate (EPIC) model was used to study the impacts of autoirrigation of corn on crop yield and soil water balance during 2019–2021 at −300 and −450 kPa for loamy ...
