CHAPTER 1
THE PROBLEM AND ITS SCOPE
Introduction
Philippine has been noted to be an agricultural country for the past years and has continually encouraging the appreciation for agricultural economy. Agricultural economy includes the production of healthy foods of which the government gave emphasis through organic fertilizer. Organic fertilizer performs a huge role in the efficiency and effectiveness in the production of food products in the country thus the government continuously finds ways to boost the organic fertilizer production in the country. Recently, the government agricultural sector found a new way of producing organic fertilizer at less cost and reducing the pollution potential of organic wastes. This new process is called
Because it is inorganic in nature, it is not a complex substance like the organic fertilizers. Therefore, nutrients from it are easily released in the available forms to be taken up by the plants from the soil system. The fast release characteristic of nutrients from inorganic fertilizers also opens the avenues for considerable losses. In greater amounts, these nutrients are being leached down with water, volatized in the air if it is nitrogenous, fixed by clay, fixed by macro as well as micro-organisms and go with eroded soil during run-off. Now, it is generally accepted that the inorganic fertilizers have low efficiencies. All inorganic fertilizers are soluble in water, and release nutrient as it dissolved and transforms to available forms. Inorganic fertilizers are not to be applied when the plant leaves are still wet because it creates fertilizer burns in the leaves. It should be taken care wisely and avoid contaminating foods. It should be stored in dry and safe places and must be applied with proper timing. (FERTILIZER USE AND MANAGEMENT: Why Organic Vs. Inorganic Fertilizers? , A Lecture Prepared/Presented During the Season-Long Rice Specialists’ Training Course on IMP held on January 9 to April 29, 1995 at Central Experiment Station, PhilRice Maligaya Muňoz, Nueva Ecija) According to Jovino L. de Dios, in common practice, inorganic fertilizers are more preferred than organic fertilizers. This is due to ease
