Corn Water Use and Evapotranspiration [PDF]

open access: yes, 2017
Crop water use (transpiration) during the growing season is a major factor in attaining high yield potential. Soil water loss (evaporation) and crop water loss (transpiration) occur simultaneously; making predictions of evapotranspiration complex. Actual

Short‐Term Agricultural Drought Prediction Using Explainable Data‐Driven Models and Quantified Uncertainty

open access: yesInternational Journal of Climatology, EarlyView.
This study demonstrates that explainable deep learning models can skilfully predict short‐term agricultural drought using standardized drought indices, capturing hydroclimatic memory and seasonal persistence. The integration of uncertainty quantification and SHAP‐based interpretability reveals the dominant role of antecedent moisture and climate ...

Food Security Versus Environmental Health: The Nitrogen Dilemma

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
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.

Crop Evapotranspiration and Irrigation Scheduling in Blueberry [PDF]

open access: yes, 2011
There are currently 139,000 ha of blueberry worldwide, including 66,000 ha of highbush [comprises northern highbush (Vaccinium corymbosum), southern highbush (Vaccinium sp.), and rabbiteye (V. virgatum formerly V. asheii) cultivars] and 73,000 ha of lowbush blueberry (V. angustifolium) (Strik & Yarborough, 2005; USHBC, 2009).

Climate Change and Reduction of Soil Organic Layer Thickness Increases Drought Risk in Mountain Forests of the Northern Alps

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background On ca. 10% of the forested sites in the Bavarian Alps (Germany) mountain, forest soils (so‐called folic histosols) are characterized by thick organic layers overlying poorly weathered calcareous parent material. Aim These organic layers play a critical role in releasing water and nutrients for vegetation, yet they are also sensitive

Synergistic effects of maize defoliation and common bean relay cropping in Western Ethiopia

open access: yesJSFA reports, EarlyView.
Abstract Background Maize defoliation is practiced to enhance crop management by improving light penetration, nutrient allocation, controlling weeds, and providing supplementary feeds for livestock. A rapid decline in soil fertility and low crop yields associated with maize‐based monocropping has prompted the recent introduction of maize common bean ...
