Amino Fertilizers: Disadvantages of Soil-Base Fertilizers
Loss Due to Evaporation
When you apply fertilizer on the soil, it takes a long slow process for it to generate food for the plant. In the meantime, some experts say about 60 percent of the fertilizer you applied have been lost to evaporation. The soil takes time to get something from the soil-base fertilizer you applied, to get the micro organisms benefited from it, and then mix soil nutrients with the action of the sun, air, and water for photosynthesis. That process produces amino acid which the plant needs as food. Then proteins are produced to make the plant grow and produce crops.
But the fact of nature is, there is the thing called evaporation. Water evaporates within minutes, and because your fertilizer is mixed with water, it evaporates with the water fast. And it's easy to see why 60 percent of your soil-base fertilizer goes to waste: water evaporates so fast and almost entirely immediately, especially under the sun.
Loss Due to Seepage
Because you applied it on the soil, your liquid fertilizer is easily seeped into it. Soil allows easy seepage for liquids, except in instances of severe flooding when soil seepage properties lessen or slow down. But then, your fertilizer easily washes away in the flood even if it does not get seeped deep into the soil, not to mention the flood ruining your plants. Some experts say about 30 percent of it is wasted through seepage. Just imagine, you buy kilos of costly fertilizer just to lose 30 percent of it to seepage. And that's not counting the quantity lost to evaporation.
10 Percent Benefit
The remainder is a measly 10 percent benefit for your plant. You buy fertilizer worth, say, P3,000 for a hectare and the benefit is only worth some P300. All the P2,700 is all trashed down the drain. And that's not counting the labor cost to have the sacks brought from the warehouse to your truck, and then from your truck to the site. And that's not counting your truck rent. If the labor cost is, say, P500, and the truck rent is P1,500, you lose about P4,700 in all each season. All that for a 300-peso benefit. What if you plant and harvest thrice a year? The loss is P14,100 per hectare with only a 900-peso benefit annually for fertilizers. What if you have 3 or 5 or more hectares? See the disadvantages of soil-base fertilizers?
The question is, is there a plant-base fertilizer? A plant-base fertilizer is applied directly to the plant, not the soil. So it's not soil-dependent. Next time, we'll discuss about the advantages of plant-base fertilizers.
