Mulching Increases Water Use Efficiency, Production and Profitability in Forage Cactus–Maize Intercropping Systems

Irrigation and Drainage, EarlyView.
ABSTRACT This study evaluated the growth, forage production, soil water balance, water indices, biological efficiency and competitive capacity of forage cactus and maize in monoculture and intercropping, with or without mulch. The experiment was conducted in Serra Talhada, Pernambuco, Brazil, using the cactus clone ‘Orelha de Elefante Mexicana’ (OEM ...

Comparing soil boundaries delineated by digital analysis of multispectral scanner data from high and low spatial resolution systems [PDF]

, 1977
The author has identified the following significant results. Computer-aided analysis techniques used with aircraft MSS data showed that the spatial resolution was sufficient to recognize each soil mapping unit of the test site. Some difficulties occurred

Yield, Evapotranspiration, Production Functions, Crop Coefficients, Water Productivity and Soil‐Water Extraction of Three Watermelon Varieties

Irrigation and Drainage, EarlyView.
ABSTRACT While watermelon is an important commodity in the United States and worldwide, some of the fundamental watermelon productivity indices (crop evapotranspiration [ETc], transpiration [Tr], evaporation [E], ET‐yield production functions [ETYPF], basal crop coefficients [Kcb], crop water productivity [CWP], soil‐water extraction [SWE]) have not ...

Beyond the Metrics: Context‐Aware Calibration for Better Drain Flow Modelling

Irrigation and Drainage, EarlyView.
ABSTRACT Robust hydrological and water quality modelling is essential for advancing the understanding and management of engineered agricultural subsurface drainage systems. Achieving credible model output hinges on calibration strategies that are both rigorous and context sensitive. At the field scale, accurately capturing the dynamics of nutrient load

Local sensitivity analysis for compositional data with application to soil texture in hydrologic modelling [PDF]

, 2013
Compositional data, such as soil texture, are hard to deal with in the geosciences as standard statistical methods are often inappropriate to analyse this type of data. Especially in sensitivity analysis, the closed character of the data is often ignored.

Field Studies on the Influence of High‐Voltage Direct Transmission Underground Cables on Soils Along the SuedLink Route in Southwest Germany

Journal of Plant Nutrition and Soil Science, EarlyView.
During regular operation of the SuedLink at a load ≤75 %, the average increase in temperature in the plowing horizon is expected to be less than 1.6°C in the soils along the route in Southwest Germany. ABSTRACT Background The SuedLink was planned as a high‐voltage direct‐current underground cable route. The construction itself is a massive intervention

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
