Cutting Through the Green: A Case for Grassland Archaeology Using UAV Multispectral Data

Archaeological Prospection, EarlyView.
ABSTRACT Advances in low‐altitude remote sensing are needed to improve the effectiveness of archaeological prospection in the Netherlands. The geomorphological situation and land use history make applying various remote sensing and geophysical technologies particularly challenging.

Seasonal drivers of plant–soil–microbial community structure and functions in Western Himalayan grasslands, Pakistan

Grassland Research, EarlyView.
Plant species richness was greater in summer in both alpine and subalpine grassland ecosystems. Soil moisture demonstrates significant positive correlations with soil organic carbon and total nitrogen across seasonal periods. Microbial α‐diversity peaks during summer but maintains functional stability across seasons.

Determination of Evapotranspiration and Crop Coefficient for Tomato by Using Non-Weighing Lysimeter in Semiarid Region

Air, Soil and Water Research
Providing an accurate amount of water to crops based on their requirements is the primary objective of irrigated agriculture. The crop evapotranspiration and coefficient of tomato were measured using non-weighing lysimeters.

The water footprint of olives and olive oil in Spain [PDF]

, 2009
This paper evaluates the water footprint of Spanish olives and olive oil over the period 1997-2008. In particular, it analyses the three colour components of the water footprint: green (rainwater stored in the soil), blue (surface and groundwater) and ...

Key soil health indicators under humid grazing lands

Grassland Research, EarlyView.
Soil health can be described using a few key soil health indicators that target a diversity of soil functions. This perspective article highlights how forage management affects these soil health indicators in humid‐zone grazing lands. Abstract Background Soil health describes critical soil functions influenced by land management. Although some key soil

A Comparative Study of Crop Evapotranspiration Estimation by Three methods with Measured Crop Evapotranspiration in Konya Plain

Selcuk Journal of Agricultural and Food Sciences, 2019
Evapotranspiration values are one of the basic data used in the planning, projecting, constructing and operating irrigation facilities.. The irrigation water needs of several plants are calculated by using various empirical equations based on meteorological data and the system is designed according to the month in which the highest irrigation water is ...

Effects of crop evapotranspiration estimation techniques and weather parameters on rice crop water requirement [PDF]

, 2014
Accurate estimation of crop evapotranspiration is key to determination of crop water requirements as well as water productivity. In this study, Microflex-C sensors were mounted on three sets of lysimeter to measure crop evapotranspiration in the paddy ...

Mapping evapotranspiration variability over a complex oasis-desert ecosystem based on automated calibration of Landsat 7 ETM+ data in SEBAL [PDF]

, 2019
Fragmented ecosystems of the desiccated Aral Sea seek answers to the profound local hydrologically- and water-related problems. Particularly, in the Small Aral Sea Basin (SASB), these problems are associated with low precipitation, increased temperature,
