Mud brick and woods storehouses save grain after the harvest
correspondent: Rob Goodier
In that location are a lot of good ways to coax more than crops out of plot of farm land. Irrigation, pest command and fertilizer are the basics, and they work. Only information technology does non make sense to increase crop production without stemming the high loss of food after the harvest, according to Sam McNeill, an associate professor of agricultural applied science at the University of Kentucky, and his colleagues who wrote a report on grain storage in Republic of ghana for the U.S. Section of Agronomics-Foreign Agricultural Service.
After the harvest, anywhere from 10 to twoscore percent of the rice, maize and other grains grown worldwide spoils or falls prey to insects, rodents and other pests. By curbing that loss, nosotros will take a long step toward feeding the growing population.The earth needs to increase nutrient production past 70 percentage by the yr 2050 to feed an extra 2.three billion people, the Un estimates.

Since 2009, McNeill and his squad accept led workshops in Ghana and Nigeria to evidence how to improve storage facilities. Good storage preserves more of the harvest, and it is also a good sales tactic. It allows farmers to wait out the market glut that follows a harvest so they tin sell their grain later when the toll is right for them.
Something as simple equally the right grain silo can make a difference in developing countries. Using McNeill's report equally a example study in Ghana, the land's economy is agrarian in which crops account for more than half of the value of goods produced nationwide. Most farms are small. Nearly eighty percentage of the crops produced nationwide are grown on smallholder farms. Post-harvest losses on those small farms runs from 30 to l percentage.
With those numbers, it is easy to run into how targeting losses on small farms could dramatically boost the amount of food bachelor in Ghana.
McNeill and his colleagues are working with farmers, grain buyers and stored-grain engineers and managers from public and private food mills, feed mills and distilleries in Republic of ghana and Nigeria. They tailor their talks to each region, taking into account climatic atmospheric condition and the materials that are locally available for storage.
"We mostly hash out the pros and cons of each type and let them determine. Research is on-going to determine the best designs, methods and materials, but nosotros do encourage farmers there to dry the ingather as soon as possible to preserve grain quality and food/market value," McNeill told E4C.
"They were eager students, enthusiastic participants during the workshops, and gracious hosts," McNeill says.
For more data, please see the Web site for the ADM Institute for the Prevention of Postharvest Loss at the Academy of Illinois at Urbana-Champaigne. And consider subscribing to their informative newsletter.
The knowledge dispensed in these talks might include this kind of silo advice:
The narrow cribs in the pinnacle row of pictures store de-husked maize. Sometimes farmers leave the corn in the cribs for besides long and grain borers and other insects infest it. The stored corn is also vulnerable to theft, and the structures are not practical for farms larger than 40 acres.
The mud silos pictured in the lesser row too store dried maize. Because they are mud, they work better in dry climates. Moisture can build on their walls, but cooking nigh them warms the walls and keeps them dry. Anecdotally, they foreclose insect infestations.
