"... (A) grand African paradox was beginning to form in Kenya: food shortages and surpluses side by side, simultaneous feast and famine. Drought was spreading in the northern and eastern reaches of Kenya, threatening herders and their livestock. The government declared a food shortage in the country and said it would be necessary to import food, either by purchasing from neighboring countries or inviting food aid, to feed the growing ranks of the hungry. ... At the same time, farmers in the breadbasket regions of western Kenya and the Rift Valley were complaining about the low prices they were receiving for their maize."

We're not normally focused on this part of the world, but something like the Japanese tsunami tends to divert your attention.

Mapping the global extent of soil constraints to crop growth plays an important role in developing strategies for agricultural production, environmental protection, and sustainable development at regional and global scales. The most widely used dataset is the Soil Fertility Capability Classification System (FCC) developed by Center for International Earth Science Information Network (CIESIN) and the Tropical Agriculture Program of the Earth Institute at Columbia University.

Conceptually, in its simplest form, one may liken the cultivation of a crop in the field to a mathematical function.

YIELD RESPONSES TO NITROGEN

As a quick demonstration to estimate crop yield levels at regional-scale with various management assumptions, this post describes how crop systems models can be used to assess yield gap of rainfed maize due to the limited supply of soil nitrogen. This methodology can help researchers to find what is the most critical factor that limits crop yield productivity in a given environment condition and how to address the constraint.

By modeling the decomposition of soil organic matter dynamics, crop systems models can simulate the effects of soil nutrient depletion under low-input extractive field management practices, as well as soil carbon sequestration under regenerative management practices.

Farming entails a great deal of choices and uncertainties. From season to season, weather varies, price fluctuates, soil degrades, pest damages, and climate changes. Farmers everywhere must cope with these uncertainties. Throughout the history of agriculture, many options have been developed to help manage these risks, increase yields, increase efficiency, and, more recently, promote the sustainability of the overall system.
