Title StatementOptimal utilization of residual soil moisture and erosion control in rice-based upland areas
General NoteMunoz, Nueva Ecija: Central Luzon State University, 1989. 79 p. -PCARRD Study No. 84-300-198)
Summary, Etc.This study aimed to determine practical ways to control erosion in upland rice-based bench terraces and strategically managed residual soil moisture to optimize its utilization for crop production. The experiment was done at Bo. Damortis, Sto. Tomas, La Union from January 1986 to December 1988. Documents centered on the effectiveness of the bench and the grade terraces and the facilities for checking soil erosion and for water conservation. Crops and cropping patterns, gross income by crop, and suggested soil erosion control measures were also gathered. Among several cropping patterns tested, the combination found promising was rice (July to October) - corn (November to January) - peanut/mungbean (January to March). A combination of rice planted in lower benches and upland crops in higher benches minimized the risk of crops' failure during late rainfall in August or September. Planting crops as early as November was advisable as the residual soil moisture lasted only up to the end of March. Available soil moisture started to deplete with minimal rainfall - becoming nil in November and critical in March till rainfall time in June to August. Regular tillage and cultivation during the dry season helped prevent cracking of the clayey soil and in the conservation of residual soil moisture for crop production. Mulching with plastic sheets covered with dry grasses and pulverized soil kept the soil moisture longer than those unmulched during the dry months. Plastic mulch used singly tends to trap heat under it and causes the soil temperature to rise which could destroy the newly transplanted seedlings. The uneven occurrence of rainfall in Region I is favorable to farm pond construction and can minimize crop failure during dry spells
