Abstract

Upland soils in West Kalimantan used for agricultural activities reach about 483,077 hectares. However, this land potential is not yet optimally exploited due to poor soil fertility. To increase its productivity, there is a need to invent technology packages that are not only effective but also efficient. This research is designed to study the growth of upland rice and the changes in certain soil properties after low-input treatment applications. This research used a Completely Randomized Design. There were 6 treatments and 4 replications. The treatment levels were P0 (no treatment), P1 (7tons of cow manure/ha + 300 kg NPK compound), P2 (15tons of cow manure/ha + 300 kg NPK compound), P3 (7tons of compost/ha + 300 kg NPK compound), P4 (15tons of compost/ha + 300 kg NPK compound), and P5 (600 kg/ha NPK compound). Parameters included plant height and dry weight, NPK absorptions, soil pH, organic C content, and NPK contents after soil treatment. The results showed that upland rice responded well to low-input amendment treatments compared to that of grow-in soil with no input treatments. Both the treatments using 15 tons of cow manure and 15 tons of rice straw compost per hectare, each plus 300 kg of NPK, were suggested to be further research topics for treatments in upland soil of West Kalimantan.

Abstract

The study was conducted in the Punggur Kecil Village, Kubu Raya Regency, on three types of land use those are langsat plantations, mixed cropping and rice fields.   Land use change or land conversion is one of the factor that decteasing soil quality. Land use changed that occurs in punggur kecil, reguires any research aim to determining the soil quality index on three types of land use, those are Langsat plantations, mixed crops and rice fields in the punggur kecil village sungai kakap, Kubu Raya District.   Soil sampling using a diagonal system at 3 study sites with 5 points. The amount of samples in the three types of land use are 15 samples. Research parameters include supporting parameters such as soil profile, structure, vegetation type, depth of ground water level, pyrite content and distance of observation location from river / sea. Soil physical properties include bulk density, moisture content in field capacity, total porosity and texture. Soil chemical properties include soil reaction (pH), N-Total, P-Available, K-exchangeble, Ca-exchangeble, Mg-exchangeble, Na- exchangeble, Base Saturation, Cation Exchange Capacity (CEC) and C-Organic. Biological properties include: earthworm population. Stages of research include determining the location of research sampling, sample analysis in the laboratory, determination of the minimum data set (MDS) with principal component analysis (PCA) as a weight index, scoring of soil indicators and determination of soil quality index. Data processing using microsof excel 2010 and statistical applications SPSS 16. The results showed langsat plantations have a soil quality index of 0.44 (medium criteria). Mixed crop land has a soil quality index value of 0.35 (low criteria). Rice fields have a soil quality index value of 0.35 (low criteria).

Abstract

Utilization of Ultisols for sweet maize cultivation has several barriers, especially low of soil acidity, CEC, nutrient availability, organic matter and high of Al, Fe, and Mn consentration. This research was aimed to know the interaction of palm oil empty fruit compost and cockle shell ash on phosphorus uptake and yield of sweet maize in Ultisols. The experiment was carried out in screen house of Agriculture Faculty, Tanjungpura University. The research used factorial design arranged in a completely randomized design (CRD) consisting of two factors treatment (CRD). The first factor is palm oil empty fruit compost consisting control (T0), 670 g/polybag (T1), 1,030 g/polybag (T2) and 1,410 g/polybag (T3). The second factor is cockle shell ash consisting (A0), 3,3 g/polybag (A1), 4,4 g/polybag (A2), and 5,5 g/ polybag (A3). Each tretments was done in 3 replication. The parameters are soil pH, C-Oraganik, P-Available, phosphorus uptake, cob length, and cob weight. The results showed T0A3 can increase soil pH highest with the value 6.08. T3A2 can increase C-Organic with the value 2.31. T2A1 can increase P-Available with the value 26.96. T2 (1,030 g/polybag) significantly affected phosphorus uptake and cob weight.

Abstract

Mikoriza merupakan hubungan simbiosis antara jamur dan akar tanaman yang saling menguntungkan. Mikoriza dapat ditemukan di hampir semua jenis tanah dan umumnya tidak memiliki inang yang spesifik, namun faktor-faktor tertentu mempengaruhi tingkat populasi dan komposisi jenis Fungi Mikoriza Arbuskular, seperti karakteristik tanaman dan sifat kimia tanah. Penelitian ini bertujuan untuk mengetahui jumlah populasi spora dan keragaman Fungi Mikoriza Arbuskular dan kesuburan tanah pada beberapa penggunaan lahan dan jenis tanah di Desa Mayak Kabupaten Bengkayang. Penelitian dilakukan mulai dari bulan September sampai November 2022. Pengambilan sampel dilakukan secara komposit dengan sistem acak berpola diagonal. Hasil penelitian menggunakan uji-t menunjukan perbedaan yang nyata antara populasi   FMA pada jenis tanah Oxisol 1.926 spora/900 gram tanah (214 spora/100 gram tanah) dan Inceptisol 1.160 spora/900 gram tanah (128 spora/100 gram tanah) yang ditanami tanaman lada sedangkan pada tanaman kelapa sawit di jenis tanah Oxisol 1.420 spora/900 gram tanah (157 spora/100 gram tanah) dan Inceptisol 1.488 spora/900 gram tanah (165 spora/100 gram tanah), menunjukan perbedaan yang tidak nyata, Jenis FMA yang terdapat pada jenis tanah Oxisol dan Inceptisol yang ditanami kelapa sawit dan lada yaitu Glomus sp, Gigaspora sp, Acaulospora sp, dan Scutellospora sp, indeks keragaman FMA menunjukkan pada kelapa sawit Inceptisol yaitu 2,07 (tinggi), kelapa sawit Oxisol yaitu 1,93 (sedang), lada Inceptisol yaitu 1,71 (sedang), dan lada Oxisol yaitu 1,92 (sedang)
