"Time for the test fields!" Song He said.
The top scorers were stunned again. Test fields? They were already going to the test fields?
Wasn't this moving a little too fast?
"For example, you're currently working on nitrogen fixation, but you've already started going down the wrong path." Song He shook the data sheets in his hand.
"The general direction is right. With an additional nitrogen-fixing function, you can save money on Nitrogen Fertilizer. In commercial applications, even cutting costs by one yuan might be enough to crush your competitors. But staying cooped up in the laboratory and working with an assumed fixed value is completely wrong."
"Do you know why? Because in the end, you're developing Ling bacteria to serve the Desert Farmland and actual agricultural production. Farmland is completely different from a laboratory. There are far too many variables!" Song He spoke more emphatically.
"As the saying goes, nitrogen grows leaves, while phosphorus grows fruit. For leafy vegetables like cabbages, greens, and amaranth, fertilization should mainly use Nitrogen Fertilizer."
"But for fruiting vegetables like Melons, Fruits, and Eggplants, Nitrogen Fertilizer is only needed as top dressing during the seedling stage. If the soil still contains high levels of Nitrogen Fertilizer after that stage, the result will be leaves without flowers, and a sharp drop in yield. Not to mention leguminous crops like soybeans and peanuts. They can fix nitrogen themselves, so adding more would be completely unnecessary."
"There are also particular considerations when applying Nitrogen Fertilizer to different soils. You all know the main ways nitrogen is lost, right? The volatilization of Ammoniacal Nitrogen, the leaching of Nitrate Nitrogen, denitrification, and fixation in soil lattices." Song He counted them off on his fingers.
"So every region's farmland has a different degree of looseness, and your Desert-to-Soil Conversion has
