In the Philippines, I learn that the Open Academy for Philippine Agriculture , OPAPA, is recommending for corn as much as 425 kg/ha (about 9 bags) (openacademy.ph). Both are impossible! Isn’t 9 kg a little too little, and 9 kg times 47 a little too much? Juxtaposed like that, with those numbers we are forced to make a paradigm shift along with country-hopping, not to mention climate change. ICRISAT is talking to poor farmers and OPAPA is talking to rich farmers, or those who can afford to raise at least PhP 10,000 (about $220) for fertilizer alone for 1 corn cropping. ICRISAT must be talking of micro-dosing, using a bottle cap to measure out the fertilizer; OPAPA must be talking of macro-dosing, using unending fistfuls of fertilizer. The ICRISAT technology is tried and test
