Leveraging browse and grazing forage estimates to optimize index-based livestock insurance

Scientific Reports
African pastoralists suffer recurrent droughts that cause high livestock mortality and vulnerability to climate change. The index-based livestock insurance (IBLI) program offers protection against drought impacts. However, the current IBLI design relying

Switchgrass Leaf Area Index and Light Extinction Coefficients

Agronomy Journal, 2011
Much of recent interest in biofuel species modeling has been for switchgrass (Panicum virgatum L.). Such modeling requires accurate simulation of light interception. We investigated the stability of the light extinction coefficient (k) in Beer's Law with data from Temple, TX; Lincoln, NE; and Elsberry, MO.

Effect of multi-nutrient complex fertilizers on growth and tuber yield of very early potato (Solanum tuberosum L.) cultivars

Acta Agrobotanica, 2013
The aim of the study was to compare the effect of multi-nutrient complex fertilizers (HydroComplex, Nitrophoska Blue Special and Viking 13 from the nitrophoska group, and Polimag S from the amophoska group) and single-nutrient fertilizers on the growth ...

Growth and reflectance characteristics of winter wheat canopies [PDF]

A valuable input to crop growth and yield models would be estimates of current crop condition. If multispectral reflectance indicates crop condition, then remote sensing may provide an additional tool for crop assessment.
