A Sensitive Band to Optimize Winter Wheat Crop Residue Cover Estimation by Eliminating Moisture Effect

Spectral Indices to Improve Crop Residue Cover Estimation under Varying Moisture Conditions

Crop residues on the soil surface protect the soil against erosion, increase water infiltration and reduce agrochemicals in runoff water. Crop residues and soils are spectrally different in the absorption features associated with cellulose and lignin. Our objectives were to: (1) assess the impact of water on the spectral indices for estimating crop residue cover (fR); (2) evaluate spectral wate...

Wheat Yields, Nitrogen Uptake, and Soil Moisture Following Winter Legume Cover Crop vs. Fallow

Long-term use of fallow in dryland wheat (Triticum aestivum L.) systems can increase erosion and decrease soil fertility. One possible solution is to grow a green manure crop during the fallow period. To evaluate the short-term effects of substituting a winter legume green manure for fallow in a 2-vr wheat rotation, a series of experiments were conducted in the Sacramento Valley of California f...

Mapping Crop Residue Cover Over Regional Agricultural Landscapes in Canada

Land management practices affect the long term sustainability of agricultural soils. Growing Forward, Agriculture and Agri-Food Canada’s (AAFC) agricultural policy framework, has identified promoting environmentally responsible agriculture as one of the department’s priorities. Land management information requirements have become increasingly important to a number of programs and policies suppo...
