Education of Location Specific Fertilizer Application on Marginal Land

Eko Hary Pudjiwati

Abstract


Fertilizer application must be done properly to prevent land degradation.
Marginal lands with low physical, chemical and biological fertility require specific
fertilization technologies. Tana Tidung Regency (KTT) has land that is mostly
classified as marginal. The technology for fertilizing specific nutrients for marginal
land locations must be understood by agricultural extension workers so that they can
be disseminated to farmers. This community service activity is in collaboration with
the Sesayap Agricultural Extension Center (BPP) and aims to increase the knowledge
and skills of agricultural extension workers in Tana Tidung Regency regarding nutrient
fertilization specific to marginal land locations. There are two activities in this
community service, namely 1) Counseling on nutrient fertilization specific to marginal
land locations; 2) Conduct site-specific fertilization demonstration plots with
integrated fertilization for sweet potato plants. The results of this community service
activity can increase the knowledge of agricultural extension workers in Tana Tidung
Regency about location-specific nutrient fertilization and can practice it through
integrated fertilization applications. Integrated organic-inorganic fertilization is proven
to provide higher sweet potato production than inorganic fertilizers. Dissemination of
site-specific fertilization with integrated fertilization application to farmers in
agricultural extension work areas can improve marginal lands and support the
realization of sustainable agricultural systems.
