Seresah di lantai hutan memegang peranan penting dalam menjaga produktivitas dan kelestarian hutan selain dapat mengendalikan erosi, mempengaruhi daur hidrologi dan unsur hara juga berfungsi sebagai penyimpan karbon.

Sampel seresah daun diambil dari tanaman jati berumur 10 tahun, dari klon-klon unggul yang berasal dari tapak yang berbeda di Jawa. Kandungan Fe dan Mn mempunyai perbedaan yang cukup besar berkisar antara ppm dan ppm, sedangkan Cu dan Zn tidak banyak berbeda berkisar antara ppm dan ppm.

Hubungan antara meyode unsur yang bersifat mobile C, N, dan P pada seresah dan tanah tidak menunjukkan tren yang nyata, sebaliknya unsur yang bersifat immobile K, Ca, Mg, dan Na selalu konsisten antara kadar unsur hara di seresah dengan kadar unsur hara di tanah.

Litter on forest floor plays a very important role to maintain forest productivity and sustainability. The litter can control soil erosion, hydrology and nutrient cycles and has a function as carbon storage. The nutrients content in the leaf litter is affected by species, genetic, kjeldaahl material, soil and climate.

The newly fallen leaves samples were taken from the clonal teak plantation at ten years old, which planted at seven different sites in Java.

The result showed that carbon content was not much different, valued K, Ca, and Mg content was slightly different valued 0. Fe and Mn content were much different among the sites ranged ppm and ppm, respectively, while Cu mmetode Zn were not much different valued ppm and ppm, respectively.

The relationship between levels of elements that are mobile C, N, and P on litter and soil do not indicate a real trend. Otherwise immobile elements K, Ca, Mg, and Na are always consistent between the levels of nutrients in the litter with high levels of nutrients in the soil.
