SIFAT KIMIA TANAH DAN PERKEMBANGAN AKAR KELAPA SAWIT (Elaeis guineensis Jacq.) PADA BERBAGAI DIMENSI RORAK DENGAN PEMBERIAN TANDAN KOSONG
Abstract: The development of
the root system of plants are a reflection of the level of physical and
chemical soil properties. Siltpit (rorak) is a conservation pit of a certain
size and layout which systematically provide benefits for soil remediation.
Empty Fruit Bunch (Tan-kos) used as an alternative of organic fertilizer and
also contribute to the improvement of physical - chemical and biological
properties of soil. The experiments were conducted with four treatments and 4
replications . Experiment arranged in Radomized Completely Block Design with
treatment EFB applications 750 kg on the soil surface with dimension 3mx2m
(T0); siltpit size 3 m x 0.66 m x 0.75 m + 750 kg EFB (T1); siltpit size 5 m x
0.6 m x 0.5 m + 750 kg EFB (T2) and siltpit size 5 m x 1 m x 0.3 m + 750 kg EFB
(T3). T2 treatment gives the most influence on the increase in the CEC of 4.8
cmol / kg then T0 of 2.8 cmol / kg. Improvement
P-dissolved is found in T3 4:06
ppm followed by T0 3.96 ppm, K-total increase 0.75 cmol/kg and K-available in
0.9 cmol/kg.T0 treatment effect significant difference in diameter, wet weight,
dry weight and root length tertiary depth of I, II and III. While treatment pit
+ 750 kg EFB (T1,T2 and T3) did not significant impact and significantly
influence on the treatment T2 in parameter tertiary root length of 27.93 mm in
depth III.
