The use of satellite images as a complement in irrigation management constitutes a
primordial basis in the decision-making process for irrigated agriculture. In this context, the …

The knowledge of soil property spatial variability is useful for determining the rational use of
inputs, such as the site-specific application of lime and fertilizer. The objective of this study …

Brazilian soils have natural high chemical variability; thus, apparent electrical conductivity
(ECa) can assist interpretation of crop yield variations. We aimed to select soil chemical …

Knowledge on spatial variability of soil properties is useful for the rational use of inputs, as in
the site specific application of lime and fertilizer. Crop-livestock-forest integrated systems …

Remote sensing applications in agriculture are presented as a very promising reality, but
research is still needed for the correct use of spectral data. The objective of this study was to …

Highlights Economy of Atlantic Canada relies on export of potatoes; Prince Edward Island
stands first in potato production. Soil variability adversely affects potato tuber yield and …

Remote sensing (RS), which is widely employed in different areas, may be used as well for
the management of agricultural systems. Among its different tools and applications, the use …

Studies on spatial variability of soil attributes of tropical pastures gather information that can
assist in decision making about managements of these soils. The objective of the present …

Large-scale phenotyping using unmanned aerial vehicles (UAVs) has been considered an
