Effects of Composting on Growth and Uptake of Plant Nutrients and Soil Chemical Properties After Composting with Various Comparison of POME

Abstract

Abstract: Effects of Composting on Growth and Uptake of Plant Nutrients and Soil Chemical Properties After Composting with Various Comparison of POME aims to find out the provision of compost with various comparisons of POME in improving soil chemical properties and to know the treatment of compost types with various comparisons of POME to Plant Nutrient Growth and Uptake research this will be carried out in the Research will be carried out in the Bangun Bandar PT. Socfindo, Serdang Bedagai district, Dolok Masihul sub-district with a height of ± 25 m above sea level. The research will be carried out in January - August 2018. As for the method used The mixture of soil and compost samples that have been incubated for 1 month is taken from each sample as much as 1 kg and analyzed the nutrients in the laboratory by the wet decstructive method pH H2O 1: 2.5 , N-Total (Kjeldahl destilation), C-Organic (Walky and Black titration), P-Bray II (spectrophometer) and CEC (Ammonium acetate pH 7). Plant Height (cm), Plant Bump Diameter (cm), Weight Measurement , Wet and Dry Weights, Weights, Dry Roots, Nisbah, Roots Results of the study Compost giving with various comparisons of POME 1: 1.3, 1: 1.9 and 1: 2.6 improves the soil chemical properties: total N incubated for 1 month. The compost treatment with various POME 1: 2.6 comparisons gave the highest results. The compost treatment with various POME comparisons significantly affected plant height, plant tuber diameter, canopy wet weight, canopy dry weight and root canopy ratio, leaf P nutrient content, Ca levels leaf and plant nutrient uptake (N, P, K, Ca, Mg). In general the treatment of compost with various POME 1: 1.9 comparisons showed the highest results.
