permanent shelters, to be used for irrigating crops
(Subagyono et al. 2004).
Besides the water availability, other things that
become obstacles in dry land farming are low
nutrients and organic material availability. Efforts
are made is fertilizer application, both inorganic and
organic fertilizer. According to Norsalis (2011),
fertilizer used in upland rice framing should be
combined between inorganic and organic fertilizer.
Provision of organic fertilizer (manure, compost and
green) can improve physical, chemical and
biological properties. Meanwhile, inorganic fertilizer
can provide nutrients in quick time.
The simple land resource technology to control
erosion and improve dry land productivity is the use
of organic materials. Mulch, organic waste, compost
and manure (organic matter) are able to control soil
erosion, improve soil physical and chemical
properties and increase crop production. Mulch from
various materials, among others, residue of crops on
dry land farm are intended to protect soil from
external forces such as rainfall splash that reduce
soil fertility and rooting. The role of crop residues
used as mulch in agricultural lands, especially on dry
land has been quite widely. Organic mulch includes
all agricultural waste materials that are economically
less useful such as rice straw, corn stalks, peanut
stalks, banana leaf leaves and midribs, sugarcane
leaves, reeds, kirinyu leaves and sawdust. With the
presence of mulch material above the soil surface,
the rainwater energy will be retained by the mulch
material so that the soil aggregate remains stable and
avoids the process of destruction and erosion. The
use of mulch will also maintain the condition of the
soil's microclimate such as temperature and soil
moisture so that the soil does not dry quickly and is
not easily cracked (Jajang, 2009).
The soil temperature in the root area is important
for plant growth and development because it affects
physiological processes in plant roots such as taking
water and mineral nutrients from the soil (Diaz-
Perez and Batal, 2002). Soil that is given platinum
mulch and organic mulch, is able to increase the soil
temperature between 1.20 - 4.19 ºC higher than soil
without mulch. Soil temperature is one of the
important micro-soil environmental factors because
it influences: soil moisture, soil aeration, soil
structure, activity of microorganisms, enzymes, and
availability of nutrients. Soil moisture is available to
plants in rice straw mulch higher than other mulch
and controls. Soil moisture that is sufficiently
available in the rhizosphere stimulates plant growth
and yield.
4 CONCLUSIONS
Efforts to improve productivity of upland rice in dry
land can be done with land use under oil palm
stands, marginal land utilization, and application of
soil conservation techniques using organic mulch.
