Geospatial data and web based tools for managing irrigation infrastructure expansion projects

World Water Policy, Volume 9, Issue 3, Page 388-403, August 2023., 2023
Abstract Improving irrigation infrastructure is important for sustaining food security in developing countries like India. The irrigation potential of a system is estimated at the planning phase using conventional approaches. A mismatch in the irrigation potential planned to be created and the land suitable for cultivation can lead to a gap in the ...

Linking animal behaviour and tree recruitment: Caching decisions by a scatter‐hoarder corvid determine seed fate in a Mediterranean agroforestry system

Journal of Ecology, Volume 111, Issue 2, Page 400-411, February 2023., 2023
The consequences of seed caching for seedling early establishment are driven by a fine decision‐making process of the disperser. Magpies seemed to ponder the characteristics of the habitat and the seed itself to determine where and how to cache each nut. By doing so, magpies reinforced the quality of seed dispersal effectiveness, as they cached walnuts

Effects of the Annual Nitrogen Fertilization Rate on Vine Performance and Grape Quality for Winemaking: Insights from a Meta‐Analysis

Australian Journal of Grape and Wine Research, Volume 2023, Issue 1, 2023., 2023
Sustainability in grapevine cultivation requires the precise use of water and fertilizers, particularly nitrogen (N), to produce grapes of the highest quality for winemaking, while simultaneously avoiding harm to the surrounding waters and atmosphere by reducing NO3− losses and N2O and NH3 emissions from the vineyards.

Effectiveness of inorganic and organic mulching for soil salinity and sodicity control in a grapevine orchard drip-irrigated with moderately saline waters

Spanish Journal of Agricultural Research, 2014
Soil mulching is a sensible strategy to reduce evaporation, accelerate crop development, reduce erosion and assist in weed control, but its efficiency for soil salinity control is not as well documented.

Agronomic and Economic Potential of Vegetation Indices for Rice N Recommendations under Organic and Mineral Fertilization in Mediterranean Regions

Remote Sensing, 2018
Rice (Oryza sativa L.) farmers in Mediterranean regions usually apply organic or mineral fertilizers before seeding that are supplemented with mineral nitrogen (N) later in the season.

Sustentabilidad del riego complementario en suelos Udipsament Típico y Hapludol Entico de Argentina [PDF]

Revista Brasileira de Engenharia Agrícola e Ambiental, 2006
El riego complementario con aguas sódicas conduce a procesos dispersivos que deterioran el espacio poroso y con ello otras propiedades relacionadas. Esto podría producirse con bajos a medios niveles de RAS del agua, en suelos gruesos, cuando la illita domina la fracción arcilla.

Feasibility of using pyranometers for continuous estimation of ground cover fraction in table grape vineyards

Spanish Journal of Agricultural Research, 2014
This paper evaluates the feasibility of using pyranometers for continuous estimation of ground cover fraction (GCF) at remote, unattended sites. Photographical techniques were used for measuring GCF (GCFref) at a table grape vineyard grown under a net ...
