Site-Specific Nutrient Management (SSNM) provides guidance relevant to the context of farmers' fields. SSNM maintains or enhances crop yields, while providing savings for farmers through more efficient fertilizer use. By minimizing fertilizer overuse, greenhouse gas emissions can be reduced, in s...

The Yaqui Valley, one of Mexico’s major breadbaskets, includes ∼230,000 ha of cultivated, irrigated cropland, with two thirds of the area planted annually to spring wheat (Triticum turgidum). Nitrogen (N) fertilizer applications to wheat have doubled since the 1980s, and currently average around ...

An important source of uncertainty in anticipating the effects of climate change on agriculture is limited understanding of crop responses to extremely high temperatures1, 2. This uncertainty partly reflects the relative lack of observations of crop behaviour in farmers fields under extreme heat...

The GreenSeeker Handheld crop sensor is an innovative diagnostic tool that farmers can use to improve their fertilizer use efficiency. Over the last decade, farmers in the Yaqui Valley, Sonora, Mexico, widely adopted the technology. Adoption led to significant increases in profits for farmers as ...
