Abstract

Land preparation to start the rice planting season in the Experimental Garden applies tillage and no-tillage systems. This study aims to assess the differences in soil physical properties on tidal rice fields with tillage and no-tillage systems in the Experimental Farm of BPSIP Kubu Raya Regency. Soil sampling used the transect method and there were 5 observation points at each soil sampling location. Soil samples were taken at a depth of 0-20 cm and 20-40 cm which are intact soil samples and disturbed soil samples while soil aggregate samples were taken at a depth of 0-20 cm. The parameters of soil physical properties include soil fraction, bulk density, total porosity, permeability rate, field capacity water content, and aggregate stability. The results showed that there were no differences in soil physical properties in tidal rice fields with tillage and no-tillage surjan systems in all soil physical properties parameters, except for the soil aggregate stability parameter which showed significantly different results, no-tillage rice fields had higher values than tillage rice fields.

Abstract

Tanah Gambut merupakan satu diantara jenis tanah di Kalimantan Barat yang cukup potensial untuk budidaya Bawang Merah. Pemanfaatan Tanah Gambut sebagai media tanam Bawang Merah banyak menghadapi kendala terutama berkaitan dengan sifat fisik dan kimia tanah yang kurang sesuai untuk pertumbuhan tanaman. Tanah Gambut memiliki pH rendah, kejenuhan basa rendah, kapasitas tukar kation tinggi, dan kandungan hara makro dan mikro yang rendah, sehingga dapat menjadi penyebab terhambatnya pertumbuhan dan produksi tanaman. Menurut badan statistik hortikultura produksi Bawang Merah di Kalimantan Barat dalam waktu 3 tahun terakhir mengalami penurunan, sehinggga perlu diupayakan peningkatan produksi Bawang Merah di Tanah Gambut dengan pemberian Pupuk Kandang Kambing dan Abu Boiler. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 2 faktor. Faktor pertama yaitu Pupuk Kandang Kambing sebanyak 3 taraf perlakuan P0 (0 g/ polybag), P1 (240 g/polybag), P2 (480 g/polybag) dan faktor kedua Abu Boiler sebanyak 3 taraf perlakuan B0 (0 g/polybag), B1 (842 g/polybag), B2 (1.148 g/polybag) sehingga total kombinasi perlakuan sebanyak 9 dan diulang 3 kali sehingga terdapat 27 unit percobaan. Hasil penelitian menunjukkan kombinasi Pupuk Kandang Kambing dan Abu Boiler tidak berpengaruh nyata terhadap semua paramater. Namun, pemberian abu boiler secara tunggal memberikan pengaruh pada semua parameter kecuali serapan P tanaman dan meningkat dibandingkan perlakuan kontrol. Perlakuan abu boiler pada perlakuan B1 (842 g/polybag) meningkatkan serapan N, serapan K, berat kering atas tanaman, jumlah umbi, berat basah umbi dan berat kering umbi dibandingkan perlakuan kontrol.

Abstract

Inceptisol is a type of soil that develops from igneous, sedimentary, and metamorphic parent materials. Inceptisol as a newly developed soil has a variety of textures, from coarse to fine, and depends on the level of weathering of its parent material. The problem of soil fertility in oil palm plantations of different planting ages is soil pH and low nutrient content, resulting in a lack of oil palm productivity. This study aims to determine the status of soil fertility and determine the recommended fertilizer dosage for oil palm plantations of different planting ages in Songga Village, Menyuke District, Landak Regency. This study was conducted on oil palm plantations owned by farmers in Songga Village, Menyuke District, Landak Regency. This study used a survey method. Observation points were determined based on 4 plots, each plot consisting of 15 points determined diagonally, from 15 observation points composited into 3 soil samples. Fertilization recommendations for each research location are at location A Urea 219.77 kg/Ha, SP-36 184.5 kg/Ha, and KCl 153.75 kg/Ha.

Abstract

Mega Timur Village, Kubu Raya Regency has a type of peat soil that is utilized by the community as a livelihood such as farming and gardening. The availability of water in the land will affect plant growth and agricultural yields, one of which is the process in the hydrological cycle that plays a very important role in controlling surface flow and the availability of water in the soil is infiltration. This study aims to identify the physical properties of peat soil and determine the differences in infiltration rates in the use of rubber plantations, oil palm plantations and mixed gardens in Mega Timur Village. The study was conducted for 4 months from September to December in Mega Timur Village, Sungai Ambawang District, Kubu Raya Regency. Sampling was carried out using the transect method with a distance between points of 20 meters at three land uses of five points each. The results of the One Way ANOVA test on land use showed that land use did not significantly affect the parameters of soil maturity, bulk density, total porosity, field condition water content and permeability at a soil depth of 0-30 cm. The constant infiltration rate in mixed gardens was 452.14 mm/hour (very fast criteria), rubber gardens were 338.33 mm/hour (very fast criteria) and oil palm gardens were 195.80 mm/hour (fast criteria).

Abstract

Tidal land has great potential for agricultural development, but the characteristics of its soil physical properties can be affected by seawater fluctuations. This study aims to examine the physical properties of soil in two types of land use, namely mixed gardens and tidal rice fields in Wajok Hilir Village, Mempawah Regency. The parameters analyzed include field capacity water content, bulk density, porosity, and soil texture. The sampling method was carried out in full at five replication points in each land, and the analysis was carried out in the laboratory of the Faculty of Agriculture, Tanjungpura University. The results showed that the highest field capacity water content was found in tidal rice fields at 199.73%, while mixed gardens only 76.98%. The bulk density of paddy soil was lower (0.4 g/cm³) than mixed gardens (0.72 g/cm³), indicating that the paddy soil was looser. The porosity of paddy soil was also higher (78%) than mixed gardens (65.27%). Both types of land have the same soil texture, namely silt loam, which supports the ability to store water and nutrients. These findings indicate that water management and organic matter content greatly influence the physical properties of soil in supporting land productivity.

Abstract

Jeruju Besar Village in Sungai Kakap District, Kubu Raya Regency, has a coconut plantation managed by the community without considering the suitability of the land to the growing requirements of the plant, resulting in decreased coconut productivity. This study aims to identify land characteristics according to coconut criteria, determine land suitability subclasses, provide suggestions for improvements based on actual limiting factors. The study was conducted in Jeruju Besar Village, Sungai Kakap District, Kubu Raya Regency with an area of 50 ha for 6 months, including field surveys, soil sample analysis in the chemistry and soil fertility laboratory and physics and soil conservation. The grid method was used to determine 10 observation points (1 point represents 5 ha) by taking composite and intact soil samples at a depth of 0–30 cm. The map overlay results show two types of soil: Haplic Sulfaquents and Sulfic Endoaquepts. The actual land suitability of coconut is classified as unsuitable (N1) with the main limiting factors being rainfall, drainage, effective depth, CEC, and flood hazard. The potential is classified as marginally suitable (S2-r) with drainage limitations. Suggested improvements include water management through the construction of drainage channels to control excess water and remove toxins resulting from shallow sulfidic depths, the addition of organic materials to increase the CEC, and land management using the surjan system to overcome flooding.

Abstract

Sweet corn (Zea mays L.) is a significant upland crop commodity. Peatlands, characterized by nutrient-poor conditions, require soil conditioners for effective sweet corn cultivation. Decanter solid application serves as an alternative to enhance plant nutrient availability. This study aims to evaluate the effect of decanter solid waste on the uptake of nitrogen (N), phosphorus (P), and potassium (K), as well as the yield of sweet corn (Zea mays L.) on Histosols. The research employed a field experiment based on a Completely Randomized Design (CRD) with six treatment levels of decanter solid, ranging from $A_0$ (control) to $A_5$ (1100 g/polybag). Data were analyzed using ANOVA (F-test), followed by Duncan’s Multiple Range Test (DMRT) at a 5% significance level. The results indicated that the $A_3$ treatment (700 g/polybag) was the most optimal dose. This dosage significantly increased plant dry weight and the uptake of N and K in the shoots, with increases ranging from 158.59% to 339.3% compared to the control. The application of $A_3$ decanter solid also resulted in a highly significant increase in crop yield, as evidenced by the weight of cobs (both with and without husks), which increased between 437.4% and 770.07% relative to the control. However, this dosage did not significantly improve P uptake in the shoots. The utilization of decanter solid waste at a dose of 700 g/polybag holds great potential for enhancing the growth and yield of sweet corn on Histosols

Abstract

The use of peat soil as a growing medium for corn plants faces various problems regarding soil fertility and low productivity. One of the materials that can improve fertility is red mud, which can increase the pH of peat soil, and goat manure as a soil fertility improver. This study aims to determine the effect of red mud and goat manure on increasing the availability of N, P, and K nutrients in peat soil. The study was conducted at the experimental field of the Faculty of Agriculture, Tanjungpura University, and soil sample analysis was carried out at the Chemistry and Soil Fertility Laboratory of the Faculty of Agriculture, Tanjungpura University. The research design used in this study was a completely randomized design (CRD) factorial pattern and Duncan's test with a 5% confidence level, consisting of 9 treatments and 3 replicates, resulting in 27 polybags (plants). The red mud treatment doses were: M0 (0 g/polybag), M1: 100 g/polybag (4 tons/ha), M2: 200 g/polybag (8 tons/ha). Goat manure treatment doses: K0 (0 g/polybag), K1: 1500 g/polybag (60 tons/ha), K2: 3000 [A3.1]g/polybag (120 tons/ha). The parameters observed were Soil Reaction (Soil Acidity), Soil Organic Carbon, Total Soil Nitrogen (N), Available Phosphorus (P), Exchangeable Potassium (K), Plant Height, and Corn Stem Diameter. Based on the research results, it can be concluded that the M2K2 treatment with 200 g/polybag (8 tons/ha) of red mud and kambi manure.
