The Effects of Organic Fertilizer Utilization in Rice Fields to the Rice Yield and Soil Fertility

บทคัดย่อ

This study considers the use of organic fertilizers to solve the lack of fertile soil in rice fields. At present, Agricultural land use and sustainable agriculture work together, but a deteriorating soil base causes a need to seek solutions that assure sustainability. One concept under consideration to help sustain soil conditions is advancing the use organic fertilizer. This type of fertilizer can increase soil organic matter and improve overall soil quality. Currently the most widely used organic fertilizer includes manure and compost, which are readily available. After application it has been shown that the soil has better physical, chemical and biological makeup. The fertilizer can improve soil aggregation, soil structure, soil aeration and soil drainage. It also improves the chemical properties of the soil, and it can increase the plant nutrients and buffer capacity of pH. The soil’s overall biological properties show an increase of nutrients, energy absorption and an inhibition to the growth of disease.
