PENGARUH KEDALAMAN MUKA AIR TANAH TERHADAP LILIT BATANG KARET CLON PB260 DAN SIFAT KIMIA TANAH GAMBUT DI KEBUN MERANTI RAPP RIAU
Abstract: Study to evaluate
the effect of the depth of water table in peatlands of the PB260 rubber
girthimmature plants (age 2-3 years) and chemical properties of peat soil has been
carried out inMeranti Estate RAPP Kampar Estuary Pangkalan Kerinci District of
Riau in December 2013.Research used descriptive method with measuring water
table depth in selected plots with girthmeasurements of planting rubber trees
planted in 2010 and 2011. At two sample plots (representingthe shallowest water
level and water level deep) dug each soil profile to the investigation
anddecision soil samples. Soil samples were analyzed at the Laboratory of BPTP
North Sumatra. Theresults showed that the water table in peatlands deeper,
reaching 88.6 cm girth will decrease thegrowth of young rubber trees. Rubber
immature plants age 2 years who has the best girth growth inground water at a
depth of 29.6 cm deep and 3 years old trunk circumference rubber girth bestgrowth
at 65.3 cm water table. Water table is within reach mean 88.6 cm cause
fasterdecomposition of peat soil is characterized by C/N ratio of lower and
lower quality (fertility) peatsoils with lower ash content, K-exchangeable,
Mg-exchangeable, P-available and P-total.
