Abstract

Rice estate development as instrument is targeting Merauke as a rice basket in the eastern part of Indonesia has been started by completing of Master Plan of Rice Estate Development. In the Master Plan, 206 cluster of production zone has been delineated, where each cluster consisted of about 5,000 ha. Rice estate development requires the appropriate land and water management planning to reach high land productivity and sustainable agriculture with minimal negative impacts to the environment. The appropriate soil and water management technologies are believed as key factors to develop this region, because most of the potential lands were swampy. The flat topography with unique and various climatic and hydrological characteristis lead to local specific land and water management. Site plan design model of rice estate should be integrated rice base crop livestock system. Since ruminant could make sinergic interaction with rice, the external input will be lower for sustainable agriculture. Amelioration, balance fertilization, and organic matter management will become technological components to determine the success of rice estate development. This paper explains the prospect of rice estate development from the view point of land and water management, organic matter, and balance fertilization in Merauke Regency, Papua.

Abstract

Soil testing calibration is a process to provide meaning of soil test value in term of crops response. Research on soil testing calibration for corn has been carried out on Typic Hapludox Cigudeg. The objectives were: 1) to determine critical point of soil test value of K, 2) to determine the application rate of K fertilizer recommendation. The split plot design was used with consisted five rate of K fertilization on three K soil status as the main plots. There were four K soil test methods assessed to determine the critical point value for corn. K availability was classified into three categories namely low, medium, and high class. The results revealed that critical value of four soil testing methods for low, medium, and high respectively were : HCl 25% (<14, 14-29, and >29 mg 100 g-1), NH4OAc pH 7(<84 ppm, 84-220 ppm, and >220 ppm), Morgan (<70 ppm, 70-180 ppm, and >180 ppm), and Mechlich I (<54 ppm, 54-135 ppm, and >135 ppm). K fertilization significantly affected to corn plant height in the low soil K status until the rate of 60 kg K ha-1 (116 kg KCl ha-1). Dry biomass significantly increased due to K fertilization on low, medium as well as high soil K status. K fertilization also improved corn grain production. The ears of corn could not develop without K fertilization. This was an evidence that K nutrient has an important role in enzyme activity and assimilate translocation. Even with low rate of K fertilization, corn has succeeded to form ears and kernels. In the low soil K status, K fertilization sharply increased dry grain, but in the medium soil K status the curve was gentler. Whereas in the high soil K status, K fertilization did not significantly affect the dry grain yield. The recommended application rate of K fertilizationfor corn on Typic Hapludox Cigudeg with low K status was 89 kg K ha-1 and in the medium status was 53 kg K ha-1. Whereas in the high soil K status, no K fertilization was needed.

Abstract

Relationship between cations adsorbed in solid phase (Qfactor) and those in soil solution (I-factor) can be expressed by quantity-intensity (Q-I) relationship curve of K that was introduced by Beckett. A laboratory experiment to study the effect of amelioration and K fertilization on K Q-I parameters was carried out on three soil families of acid upland mineral soil from Cigudeg, Kentrong, and Papanrejo. The experiment was arranged using completely randomized design with 2 factors. The first factor was three kinds of ameliorant and the second factor was three levels of K fertilization. The result suggested that amelioration with dolomite and steel slag increased K buffering capacity (PBCK) due to the increase in cation exchange capacity (CEC) and Ca and Mg concentration of the soil solution.Conversely, amelioration decreased equilibrium activity ratio of K (ARKe) due to alteration of K-Ca?Mg equilibrium. Amelioration, however, did not affect labile-K, except for Cigudeg soil. The application of K fertilizer increased K availability in terms of ARKe and labile-K. Those three soil families performed different changes in K availability effect, where soil with higher CEC showed smaller change than the lower one, also tended todecrease K buffering capasity (PBCK). The implication of this study is amelioration practice must be followed by K fertilization in order to avoid plant deficiency in K nutrient.
