Abstract:
Andisols, that a variable charge soil, dominates West Java tea plantation land.
Soil ameliorant is a substance added to soil that can be both organic and anorganic
material such as compost, manure or chemical material and has a function to improve soil
quality and plant growth. The study aims to select 10 ameliorants incubated in to the
Andisols for 3 months that provided the best response to young tea plants. The
ameliorants used were tea pruning litter, weed litter, mucuna cover crop, fluff (waste of
tea product), sheep manure, chicken manure, cow manure, biogas waste of cow manure,
worm casting, humic acid liquid. Completely Randomized Design was applied consisting
11 treatments including a control with 3 replications. Plant growth measurements namely
number of leaves, plant height, stem diameter shown by the best 3 ameliorants that were
worm casting, weed compost and sheep manure. The result of this study was in
accordance with changes in increase in zero point of soil charge status that support to
improve better vegetative growth
