The Effects of Doses and Methods of Lime Placement to N, P, K, Ca, Mg Content into the Leaves and Sugarcane Growth in Ultisol Seputih Mataram Lampung Tengah Heri Wahyudi*, Azwar Maas, Eko Hanudin, Sri Nuryani Hidayah Utami Department of Soil, Faculty of Agriculture Universitas Gadjah Mada Jln. Flora no. 1, Bulaksumur, Sleman, Yogyakarta 55281, Indonesia *Corresponding email: heriwahyudi22@yahoo.co.id ABSTRACT Land circumstances on Seputih Mataram, Lampung included in dried area consisted of ultisols soil. Ultisol has pH less than 5.5 caused the amount of soil nutrient absorbed to be not optimal yet. This research aimed to know the effect of adding dolomite to the soil chemical content (pH of H2O, KCL, content of N, P, K, Ca, Mg, Organic-C, C/N, Al-exc, H-exc, CEC), nutrient content on the leaves (N, P, K, Ca, Mg), and sugar cane physic. This research used Completely Randomized Design in 2 factors with 3 replication. The first factor was the dolomite dosses with 6 levels: without the dolomite (K0), 500 kg ha -1 (K1), 1,000 kg ha -1 (K2), 2,000 kg ha -1 (K3), 4,000 kg ha -1 (K4), and 6,000 kg ha -1 (K5). The second factor (R) was the depth of dolomite application: (R1) dolomite with 0-20 cm deep, and (R2) dolomite with 20-40 cm deep. The observation was done to know the soil chemical content, the leaves nutrients, and the variables that could be used into the research. The result showed that the depth of dolomite did not have significant effect to the amount of Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca), and Magnesium (Mg) in leaves. Dolomite addition had significant effect for Calcium (Ca) absorption in leaves, but it did not significantly affect the leaves absorption. Dolomite addition had significant effect in the leaves content and Magnesium (Mg) leaves absorption. 6,000 kg ha -1 dolomite for physical soil characteristic ( pH H2O, pH KCL, C/N ratio, K, P, Ca, Mg, Exch-H), leaves nutrient ( N, K, Ca), Mg and Ca absorption on leaves also sugar cane tonnage per hectare showed the maximum result.

In addition, sugar is also important for industries. Sugar is currently becoming a problem due to the lack of domestic sugar production, while the demand continues to increase. To meet the domestic sugar demand and reduce sugar import, the production of sugar raw material which is sugarcane should be increased. The Sugar Group Companies land condition belongs to a dry land (soil taxonomy) with Ultisol soil type. Ultisol is often associated with infertile soil, but in fact it is potential to be used for agricultural land in proper managements which pay attention to the existing problems (constraints). Ultisol can also be a potential land if the climate is supporting. Ultisol has pH of less than 5.5. The soil pH is determinant in controlling other chemical soil properties and characteristics for soil fertility. One of efforts in improving sugarcane productivity is by intensification (increasing sugarcane production per unit of land area). The most common intensification methods are good land processing, balanced fertilizing, using superior varieties, selecting proper time for planting and harvesting, and proper weed and pest controlling. Another problem of intensification is the need of manpower in agriculture which is more difficult to get from time to time, because manpower is more expensive and less available. This manpower is required for land management activities such as for applying fertilizer.
