Analysis of soil water content and crop yield after biochar application in field conditions

Plant, Soil and Environment, 2017
Biochar has been studied extensively in terms of its influence on soil hydrophysical properties, but only small part of results was obtained from the field experiments.

Improving crop condition monitoring using phenologically aligned vegetation index anomalies – A case study in central Iowa

International Journal of Applied Earth Observations and Geoinformation
Timely monitoring of crop conditions is essential for optimizing and assessing agricultural management. Vegetation indices (VIs) derived from remote sensing data can be useful for assessing crop conditions on a large spatial scale.

Hydrological Factors for Phosphorus Transfer from Agricultural Soils

, 1999
Understanding and managing against phosphorus (P) transfer from agricultural soils to receiving waters is a multidisciplinary task in which the role of hydrology is particularly difficult to simplify. We review current knowledge to define the spatial and temporal controls on P transfer from agricultural soils via the various hydrological pathways ...

Potential of Biochar to Alternate Soil Properties and Crop Yields 3 and 4 Years after the Application

Agronomy, 2020
Several studies have reported that biochar can improve soil properties which are linked with higher crop yields and this effect is long-term. This paper aimed to study the effects of biochar (0, 10 and 20 t ha−1) and its combinations with N-fertilization
