Audit your harvesting, handling, packaging, and storage practices. Calculate your exact dollar loss and find simple, low-cost solutions to save up to 30% more food and profit.
In Africa and developing agricultural regions, smallholders lose between 20% and 40% of their harvest to rotting, crushing, weevils, and moisture before it ever reaches a consumer's plate.
Reducing your harvest losses by just 15% gives you the exact same profit boost as expanding your farm by 15%—without needing more land, more seed, or more fertilizer. This tool audits your handling chain and highlights your top 3 profit leaks.
A farmer's effort does not end at harvesting. Learn the science and practical tricks of grain drying, onion curing, fruit crating, and weevil defense.
You don't need an expensive electric moisture meter to test if your maize or beans are dry enough for storage! Take a clean, dry glass jar, fill it 70% with grain, add 2 tablespoons of dry table salt, and shake vigorously for 1 minute. Let it settle for 10 minutes. If salt sticks to the glass walls, the grain is still damp (> 14% moisture) and will rot. If the salt falls cleanly to the bottom, the grain is safe (< 13% moisture) to bag!
Never pack fresh onions or potatoes into sacks right after pulling from the field. Curing means spreading them in a single layer in a shady, warm, well-ventilated barn for 10 to 14 days. During curing, onion necks shrivel tightly shut (sealing out rot bacteria) and potato skins thicken and toughen, doubling their shelf life.
Purdue Improved Crop Storage (PICS) bags contain two inner airtight high-density plastic liners inside an outer woven sack. When grain is sealed at safe moisture, insects breathe up the tiny trapped oxygen within 24-48 hours and die naturally. You get 100% insect-free grain without buying chemical powders.
A ZECC is a low-cost, electricity-free cooler built using a double-brick wall with wet river sand packed in the gap. Evaporation of water from the sand cools the inner room by 10°C to 15°C below outside ambient heat and maintains 90% humidity, keeping tomatoes, spinach, and mangoes fresh and crisp for 10-14 days.
Aflatoxin is a poisonous chemical toxin produced by the soil fungus Aspergillus flavus. It happens when crops are stressed by drought near harvest, dried directly on bare dirt, or bagged while still wet (> 13.5% moisture). Aflatoxin causes liver cancer and stunting in children. Prevent it by drying crops on plastic tarpaulins and ensuring grain is bone dry before bagging.
Soft perishable fruit cannot bear excessive weight. When crates are stacked more than 5 high or packed in flexible sacks, the weight of the upper 40kg pushes down onto the bottom layer, crushing cell walls. Once fruit is punctured or bruised, bacterial soft rot spreads to the entire box within 36 hours. Always use rigid stackable plastic crates.
Install simple rodent baffle guards! Cut circles or cones out of old metal iron sheets or opened metal tin cans and nail them upside down (like a funnel pointing downwards) around every wooden support pole of your granary at least 1 metre above the ground. Rats and mice cannot climb past the smooth downwards metal lip.
