KAJIAN POROSITAS TANAH LEMPUNG BERPASIR DAN LEMPUNG BERLIAT YANG DITANAMI JAGUNG DENGAN PEMBERIAN KOMPOS (STUDY OF SANDY LOAM AND CLAY LOAM SOIL POROSITIES ON PLANTED MAIZE WITH COMPOST APPLICATION)

Abstract

ABSTRACT

The research aims to determine the effect of compost on soil porosity of sandy loam and clay
soils and to see its effect on the growth of Maize plants. This research was conducted at Greenhouse
and at Soil Physics and Soil Conservation Laboratory from May until June 2017. The results showed
that the addition of compost to soil can increase soil porosity and also the addition of compost to clayey
textured soil increased the porosity compared to the sandy loam textured soils. Application of compost
tends to increase plant height and dry weight on all age of plants; i.e. 10 days after planting, 30 days
after planting and 40 days after planting. Application of compost at a dose of 10 tonnes/ha gives the
highest plant height on sandy loam soils and the heaviest plant dry weight on clayey loam soils.
