Abstrak. Akumulasi P tanah sawah di Jawa Barat sudah sangat tinggi dan ini menyebabkan P tersedia yang dapat dimanfaatkan tanaman menjadi sedikit. Bahan induk (aluvium, sedimen dan volkan) berpengaruh terhadap dinamika, proses akumulasi, dan transformasi P di dalam tanah. Penelitian ini bertujuan untuk mengetahui bentuk fraksi P dan membuat model persamaan regresi untuk mengestimasi hubungan fraksi P dengan beberapa sifat kimia tanah. Metode penelitian yang digunakan yaitu survei lapang untuk pengambilan contoh tanah dan analisis tanah di laboratorium. Lokasi penelitian adalah tanah sawah di Jawa Barat. Pengambilan contoh tanah dilakukan secara komposit pada tiga garis transek dari utara ke selatan wilayah Jawa Barat pada 60 lokasi pada lapisan tanah 0-20 cm. Penetapan fraksi P tanah di laboratorium mengikuti prosedur fraksionasi secara sekuensial sesuai metode Tiessen dan Moir yang dimodifikasi. Hasil penelitian menunjukkan bahwa akumulasi P tanah sawah di Jawa Barat didominasi fraksi residual-P, NaOH-Po dan NaOH-Pi. Ketiga fraksi ini paling banyak ditemukan pada kelompok tanah sawah berbahan induk volkanik, kemudian sedimen dan terakhir aluvium. Ada tiga faktor utama yang berpengaruh terhadap distribusi fraksi P, yaitu: 1) Fe dan Al oksida, 2) C-organik dan kadar klei tanah, dan 3) basa-basa dapat ditukar, terutama Cadd. Model persamaan regresi yang cukup baik dalam mengestimasi fraksi P tanah sawah adalah model estimasi untuk fraksi NaOH-Pi dan NaOH-Po dengan nilai R2 > 0,4 pada taraf p < 0,05.Abstract. The accumulation of P in paddy fields of West Java is high, causing low available P for plants. The parent material (alluvium, sediment and volcanic materials) influences the dynamics, accumulation, and transformation of P in the soil. This study aims to determine the relationship of P fractions with selected soil chemical properties. The research method used was a field survey for soil sampling and soil analysis in the laboratory. The research location is paddy fields in West Java. Composite soil samples from 60 locations from three transects extending from north to south of the West Java where taken from a soil depth of 0-20 cm. Determination of soil P fraction follows the sequential fractionation procedure according to the modified Tiessen and Moir method. The results showed that the accumulation of P in paddy fields of West Java was dominated by residual-P, NaOH-Po and NaOH-Pi fractions. These three fractions are most commonly found in the group of volcanic parent materials, then followed by sedimentary and alluvium parent meterials. There were three main factors that influence the distribution of the P fraction, namely: 1) Fe and Al oxides both crystalline and amorphous, 2) organic C and soil clay content, and 3) base saturation especially excheABLE Ca. The regression equation models which are quite suitable for estimating the P fraction of paddy soil are the estimation models for NaOH-Pi and NaOH-Po fractions with R2 > 0.4 at p < 0.05.

A mixture of fishpond sediment and goat manure can be used to increase the growth and yield of sweet corn. This research aimed to determine the effect of pellet from the combination of fishpond sediment and goat manure with a ratio 1:1 on nutrient (N, P, and K) and yield on sweet corn. The land used was Ultisol Dramaga which was located in Cikabayan Experimental Farm, Bogor Agricultural University. The study was conducted in a greenhouse with a Completely Randomized Design (CRD) of one factor with eleven treatments: without treatment (control); standard fertilization (Urea 0.43 ton ha-1, SP-36 0.41 ton ha-1, and KCl 0.25 ton ha-1); three doses of pellet (20 ton ha-1, 30 ton ha-1, and 40 ton ha-1); three doses of fishpond sediments (10 ton ha-1, 15 ton ha-1, and 20 ton ha-1); three doses of goat manure (10 ton ha-1, 15 ton ha-1, and 20 ton ha-1). The result showed that giving 40 ton ha-1 pellet had a significant effect on the increasing pH, ammonium, and the availability of K in Ultisol and nutrient content of P, K, and the weight of dry-grain sweet corn.

Rice is a strategic commodity, so efforts to increase its production continue to be carried out, one of which is by increasing fertilization efficiency. The government has set policies in the field of fertilization, one of which is to provide fertilizer recommendations for rice plants based on specific location. The objective of this research was to evaluate the fertilization policy written in Permentan RI No. 40/Permentan/OT.140/4/2007. The methods were analyzing the variance values for each type of fertilizer recommended and validating N, P, and K levels in selected locations. The results of the study showed that the fertilization recommendations set by the government still need to be improved because there were still many discrepancies with conditions in the field. The adjustment of recommendation dose with the addition of organic materials were relevant and can be implemented, but it is still required further socialization to farmers. Reformulation of subsidized fertilizers, from NPK fertilizer 15-15-15 to NPK fertilizer 15-10-12 also had not been able to increase fertilization efficiency, because it actually made the dose of NPK becomes higher, but did not reduce the addition of a single fertilizer significantly. Subsidy policy also needs to be reviewed, because farmers did not fully get subsidized fertilizer so the farmers could not meet the needs of their fertilizers. Regarding the implementation of fertilization information, a soil big database must be created nationally to make specific location fertilization recommendations, and this must be easily accessed by farmers. Keywords: fertilization policy, organic material, soil big database, subsidy

ABSTRACTThe management and fertilization of shallot cultivation in Brebes is very intensive. The purpose of this research was to study crop management and phosphorus (P) and potassium (K) fertilizations of shallot cultivation by smallholder farmers in four villages in Brebes. The data were collected through survey method, interview, and questionnaires to 14 respondent farmers, and analysis of P and K content of farmer's soil samples. The results showed that the cropping index (IP) was 400-500% comprised of three to four times of shallot cultivation and one rice cultivation. The fertilizations of P and K were 22-171 kg of P2O5 ha-1 and 22-213 kg K2O ha-1, respectively, while the recommended rates were 54 kg P2O5 ha-1 and 78 kg K2O ha-1, respectively. This varied fertilizations were not significantly correlated with productions, except fertilization of K with production in rainy season that was significantly correlated at P < 0.05 (n = 14, r = 0.532). The soil P status was very high at all locations and at all depths (0 - 80 cm), while the soil K status ranged from medium to very high.

One of the efforts that can be done so that the fertilization of phosphorus (P) accommodate the P needs of big red chili is by conducting soil analysis and determine the critical level of P in the soil related to the yield. The objective of this research was to determine the critical level of P for big red chili in Java Island. Soil samples were collected from 19 locations in Java Island. The soil P before planting of 19 locations was determined by three methods of P extraction namely Bray 1, Olsen, and Mehlich III. After soil P analyses, big red chili was planted in a pot containing 500 g of soil (oven-dry weight) from 19 locations where each location had 4 rates of P fertilization. The rates of P fertilization applied were 0, 55, 110, and 220 kg ha-1 P2O5. Urea and KCl were applied with the rate of 110 kg ha-1 and 180 kg ha-1 respectively as basal fertilizers. Plant biomass was harvested after the age of 4 weeks after planting. The effect of P fertilizer on growth parameters was evaluated using analysis of variance. The critical level of soil P was determined by the Cate and Nelson method. The results showed that P fertilization had a significant effect on plant height, fresh weight and dry weight of plants. Fertilization treatment of 220 kg ha-1 P2O5 resulted in the highest responses to plant growth parameters. The correlation test results showed that Bray 1, Olsen and Mehlich III extraction methods significantly and positively correlated with plant dry weight. The Olsen extraction method showed the highest correlation with plant dry weight (r=0.665). The critical levels of P in the soil for big red chili in Java determined by Bray 1, Olsen, and Mehlich III extraction methods, were 15 ppm, 40 ppm, and 50 ppm, respectively.

One month of incubation experiment was implemented to evaluate the changes of phosphorus fraction in inorganic P (Pi) and organic P (Po) induced by phosphorus fertilizer (KH2P04),cow manure ( manure) and CaC03 (lime). A 0.5 kg oven-dried weight of arable layers of Latosol from Darmaga, Bogor was used in this study. The rates of manure were 0, 12.5 and 25 ffha, lime were 0, 1, 3 times the CaC03 equivalent required to neutralize exchangeable aluminum amounting to 0, 3.01, 9.03 t/ha respectively and the rates of phosphorus fertilizer in KH2P04 were 0, 40 and 80 kg Plha. All treatments increased resin-Pi (biologically available P). Application of phosphorus fertilizer also increased NaHC03-Pi which is also included as biologically available PI whi!e manure and lime only tended to increase this fraction. Phosphorus fertilizer and manure application were able to enhance NaOH-Pi (moderately resistant P related to AI-P and Fe-P ) but lime did not affect it.Phosphorus fertilizer, manure and lime increased HCI-Pi (moderately resistant P related to Ca-P).The changes of NaHC03-Pi to resin-Pi and P immobilization by microorganism, which was indicated by the increase of NaHCOrPo (readily mineralizable), can be attributed to the decrease of NaHC03- Pi. The increase of NaOH-Pi by phosphorus fertilizer and manure indicated that the complexation of P fixation sites by PO6 and organic acids likely had occurred.

In acid soils, phosphorus (P) sorption is generally attributed to hydrous oxides of Fe and Aluminum (Al) particularly in tropical soils with low pH. However, reports concerning the role of exchangeable Al in P sorption mechanism are very little. Phosphorus (P) sorption isotherms were studied in fifteen acid upland soils containing different amounts of exchangeable Al. P sorption characteristics were satisfactorily described by the Langmuir equation. which was used to determine P sorption maxima and bonding energies, with r values ranging from 0.97 to 0.99. The soils varied widely in their capacities to sorb P. P sorption maxima ranged from 303 to 1,429 mg kg-1 (mean 627 mg kg-1) and bonding energies from 0.65 to 8.00 L mg-1 (mean 2.39 L mg-1). Exchangeable AI was found not correlated with P sorption maxima (r = -0.11) but significantly correlated with P bonding energies (r = 0.68**). This was clearly shown by clayey soils from Java and Sumatra but not in sandy soils from Kalimantan. The results suggested that in general, the reaction of exchangeable Al with P increased P bonding energy but exchangeable Al was not the main component in P sorption maximum. Keywords: Exchangeable Al, P bonding energy, P sorption maximum

The effect of calcium silicate CaSiOJ the phosphorus (P) sorption characteristics were studied in Andisols Lembang.The amount of 0, 2.5 and 5% CaSiOJ (calcium silicate) or 0, 7.5 and 15 g calcium silicate per pot was added to the 300 g(oven-dry weight) soil and incubated for one month. A completely randomized design in double replication was set up. After one month incubation, P sorption and P sorption kinetic experiments were conducted The results of P sorption experiment showed that P sorption data were satisfactorily described by the Langmuir equation. which was used to determine P sorption maxima, bonding energies and P sorbed at 0.2 mg P £"' (standard P requirement). The application of calcium silicate did not affect significantly P sorption maxima but decreased significantly the P bonding energies. Calcium silicate also decreased significantly the standard P requirements. As for P sorption kinetic experiment. the results showed that application of 5% calcium silicate decreased significantly the rate constant of P sorption and P sorbed maximum at given amount of added P. The results suggested that the application of calcium silicate to the Andisols made added P was more available for plant.

Percobaan mengenai evaluasi perubahan fraksi-fraksi fosfor (P) karena pemberian kotoran sapi pada budidaya jagung dilaksanakan di desa Cibadung Gunung Sindur, Jawa Barat. Dosis kotoran sapi yang digunakan adalah 0, 10, 20, dan 40 ton ha-1. Percobaan dilakukan menggunakan rancangan acak lengkap dengan tiga ulangan. Pengambilan contoh tanah dilakukan setelah dua minggu inkubasi dan setelah panen. Contoh tanah diambil di rhizosfer dan antar baris tanaman. Perubahan fraksi-fraksi P dievaluasi dari hasil pengurangan nilai suatu fraksi P pada saat panen dengan nilai suatu fraksi P setelah dua minggu inkubasi. Hasil menunjukkan bahwa pemberian kotoran sapi nyata meningkatkan fraksi resin-Pi, fraksi NaHCO3-Pi dan NaOH-Pi. Nilai fraksi-fraksi P tersebut pada saat panen lebih tinggi di rhizosfer dibandingkan dengan nilai fraksi-fraksi P di antar baris tanaman. Perubahan resin-Pi di rhizosfer dan antar baris tanaman adalah negatif yang menunjukkan bahwa resin-Pi telah bertransformasi ke fraksi P yang lain. Perubahan fraksi NaHCO3-Pi dan NaOH-Pi tidak konsisten positif baik di rhizosfer dan antar baris tanaman dengan meningkatnya dosis kotoran sapi. Hal ini menunjukkan bahwa pengambilan P oleh tanaman, pelepasan P dan transformasi P ke bentuk yang lebih stabil mempengaruhi jumlah peningkatan fraksi NaHCO3-Pi dan NaOH-Pi.

Dinamika fraksi-fraksi P dan sifat kimia lainnya pada tanah sawah terkait dengan indeks pertanaman padi sawah (IP) dan kadar air tanah pada kondisi lapang (KAL). Penelitian eksploratif ini bertujuan mengevaluasi pengaruh IP berbeda yang direpresentasikan oleh dosis ameliorasi dan pemupukan serta KAL sebagai representasi praktik pengairan yang diaplikasikan oleh petani pada tanah sawah penelitian terhadap dinamika fraksi P, sifat kimia tanah lainnya dan produksi padi sawah. Contoh tanah komposit diambil pada lahan sawah yang sedang dibudidayakan petani dengan IP 100%, 200% dan 300% pada periode 7, 9, 11 dan 13 minggu setelah penggenangan awal. Fraksionasi P dilakukan untuk memperoleh fraksi PH2O, PNaHCO3-inorganik (Pi), PNaHCO3-organik (Po), PNaOH-Pi, PNaOH-Po dan PHCl tanah. Nilai KAL pada keempat waktu pengambilan contoh tanah pada IP 100% < IP 200% ≈ IP 300%. Sifat-sifat kimia dan fraksi-fraksi Po pada IP 100% cenderung menurun, sedangkan fraksi-fraksi Pi cenderung meningkat dengan peningkatan KAL. Dinamika fraksi-fraksi P tanah pada ketiga IP terutama ditentukan oleh Corg. Peningkatan Corg tanah menurunkan kadar Pi pada IP 100% dan Po pada IP 200%, tetapi meningkatkan Pi pada IP 300%. Penurunan dosis P2O5 dan peningkatan dosis jerami menurunkan Eh tanah. Faktor yang paling berpengaruh terhadap produksi padi sawah adalah KAL. Kata kunci : Pupuk P, jerami padi, kadar air lapang tanah, fraksi P tanah
