PENGARUH LINTASAN TRAKTOR RODA EMPAT DAN PEMBERIAN PUPUK ORGANIK TERHADAP PER…
Abstract: Soil processing is a form of mechanical activity on soil that is carried out to obtain a good soil condition that is suitable for plant growth. The purpose of this study was to find out some changes in the physical-mechanical properties of soil due to four-wheeled tractor trajectories and the effect of organic fertilizer on the growth and production of lettuce. The research method used was experimental design which was arranged in a split plot design, using two factors (main plot an…
