Measuring Crop Evapotranspiration Over Hilly Areas

, 2018
Agricultural production systems around the Mediterranean basin rely mostly on rainfed agriculture in hilly watersheds, although some irrigation is sustained downstream of water reservoirs. With climate change and increasing demand for water, most commonly cultivated species, particularly cereals, are exposed to high risks of water shortages during the ...

Irrigation management practices of cabbage farmers in Botswana using saline groundwater. [PDF]

, 2009
All horticultural production in Botswana is irrigated, as average rainfall is less than average reference evapotranspiration in all parts of the country for all of the year, and most of the irrigation in the country is used for horticultural crops. In

Changing Water Resources in the Indus Basin: A Multi‐Model Budyko‐Based Analysis

International Journal of Climatology, EarlyView.
Budyko‐based analysis evaluates historical (1962–2005) and future hydroclimatic change across the Indus River Basin. Budyko shifts indicate rising atmospheric evaporative demand and increasing energy limitation under future scenarios. ABSTRACT Assessing hydroclimatic variability and future water availability is crucial for sustainable water‐resource ...

Sewage Sludge and Cashew Bagasse Biochars Promote Changes in Selected Physical Attributes Related to the Structure of Degraded Dryland Soil

Journal of Plant Nutrition and Soil Science, EarlyView.
This study evaluated biochars from co‐pyrolysis of sewage sludge and cashew residues on physical quality of a degraded loamy sand soil. SPB applied at 20 Mg ha−1 reduced bulk density by 7.74%, whereas most porosity attributes were driven by soil reconsolidation rather than biochar. Aggregate stability varied with biochar type, with SPB promoting larger

Crop water use or evapotranspiration

, 2000
Crop water use, also known as evapotranspiration (ET), represents soil evaporation and the water used by a crop for growth and cooling purposes. This water is extracted from the soil root zone by the root system, which represents transpiration and is no ...

Soil Loosening of Compacted Urban Tree Sites Using a Pneumatic Lance Injector: Quantifying Treatment Success Through Tree Morphology and Soil Structure Parameters via Terrestrial Laser Scanning

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Urban trees provide essential ecosystem services, but their growth and longevity are often limited by soil compaction. Although pneumatic lance injection (PLI) is increasingly promoted as a minimally invasive and efficient soil loosening technique, but robust scientific evidence for its long‐term effectiveness remains limited.

Modelling Evapotranspiration of Container Crops for Irrigation Scheduling

, 2011
Irrigation is now recognized as an important component in the agriculture economy of Mediterranean regions. As practiced by many growers, it is often based on traditional application methods that fail to measure the supply of water needed to satisfy the variable requirements of different crops.

Optimising Sulphur Fertilisation in Ryegrass–White Clover Swards Reduces Leached Nitrate Nitrogen Losses, While Increasing Plant Yield and Nitrogen Off‐Take

Journal of Plant Nutrition and Soil Science, EarlyView.
The inclusion of sulphur at two inorganic nitrogen rates (0 and 150 kg N ha−1) improves plant productivity in a ryegrass–white clover sward and reduces nitrate‐N loss to groundwater in a free‐draining sandy loam soil. ABSTRACT Background Reducing nitrogen (N) losses to water, lessening reliance on inorganic fertiliser and maintaining agricultural ...

Comparison of different reference evapotranspiration (ET0) models and determination of crop-coefficients of french bean (Phesiolus vulgaris.) in mid hill region of Meghalaya

Journal of Agrometeorology, 2017
The water requirement and crop evapotranspiration (ETc)is determined using reference evapotranspiration (ET0) and crop-coefficient (kc). Numerous models are available for estimation of ET0,among which Penman-Monteith (FAO-56) model is considered to be ...
