The cover is the most important measures, and is versatile platform enables the management and sustainable land use. Can cover with plastic or live vegetation, the availability of organic matter such as crop residues to protect and improve land. Mulching with crop residues bagasse, straw, grass, dried leaves have a significant effect to the concentration of nutrients in the soil, significantly increased levels of organic matter in the soil as humus content, protein, phosphorus, potassium and digestion of the soil, and thave a moisturizing effect for higher ground, especially during hot weather and long-term average from 20.19 to 54.27 percent
reducing soil temperature significantly from 2.51 to 6.40oC plus mulching weed mass limit from 73.67 to 97.65 percent over the control to nature, whereby the number of microorganisms in special soil microorganisms total, microbial resolution phosphorus, cellulose is the best recipe using bagasse cabinet on all three crops. The effect brought about the economic mulching with crop residues increased yield from 6.1 to 21.7 percent.
