Sagip-Lupa (GSL) Soil Conservation Technology and Weed Management is a study that advocates for the technology that shall address the concerns of preventing soil erosion through sustainable agriculture. GSL also seeks to determine the best option that is environmentally friendly, safe to users, cost effective and practical to use in light of sustainable agriculture. The project started in February 2005 to end this year 2010. The five (5) study sites are Quezon (corn-corn-corn) with slope topography of 12%, Batangas (upland rice-corn-upland rice)-topography of 10%, Benguet (potato-cabbage-potato)-topography of 30%, Isabela (corn-corn-corn)-topography of 15-20% and Nueva Ecija (lowland rice)-flat topography. There were two treatments in the study. The use of non-selective, contact and post emergent herbicide (NSH) at the rate of 2-3 li-prod/ha versus the conventional farmer's practice (FP) of weed management. The results showed significant soil erosion reduction in all GSL sites as compared to FP. GSL percent soil erosion reduction over FP in Quezon, over a period of 5 years was 62.90%, 56.31% in Batangas, 55.05% in Benguet and 52.10% in Isabela. Another advantage of the GSL technology is economic benefits. Reduced input costs were found to all GSL sites. Cost savings over FP was 37.96% in Quezon (corn); 20.61% (upland rice) and 26.38% (corn) in Batangas, 58.85% (cabbage) and 61.86% (potato) in Benguet, 35.12% in Isabela (corn) and 44.7% cost savings in Nueva Ecija (rice). Five-year period in the GSL treatments and sites showed significant trends of yield increase over FP. Over-all, the GSL technology on its 5th year proved to be an effective alternative remedy in minimizing soil erosion, while providing high yield and excellent weed control in sloppy areas.
