Abstract

Penelitian ini bertujuan untuk mengetahui beberapa sifat kimia tanah pada lahan perkebunan kelapa (Cocos nucifera L.) dan memberikan saran pemupukan unsur hara N, P, dan K untuk tanaman kelapa. Penelitian dilakukan dengan menggunakan metode jalur sistematik (transek) yang mencakup tiga lahan milik petani yang berbeda, masing-masing terletak pada jarak lahan A 2,8 km, lahan B 2,7 km, dan lahan C 2,4 km dari sungai. Pengambilan sampel tanah dilakukan secara komposit, dengan lima titik pengambilan sampel pada setiap lahan yang ditentukan melalui metode diagonal. Setiap lahan perkebunan kelapa (Cocos nucifera L.) menunjukkan beberapa sifat kimia tanah yang beragam. Lahan A, B dan C memiliki pH tanah yang masam, sehingga kadar fosfor yang tersedia rendah, namun kandungan C-organik sangat tinggi yang berdampak pada meningkatnya kadar N-total dan KTK tanah yang sedang. Berdasarkan hasil analisis tanah dari ketiga lokasi lahan penelitian lahan A, B, dan C, memiliki kriteria sifat kimia tanah yang sama pada parameter pH, C-organik, Ca, Mg, dan KTK, namun adanya perbedaan kriteria pada parameter N, P, K dan KB terutama pada lahan C. Saran pemupukan untuk lahan A - 102,26 kg/ha pupuk urea, 28,9 kg/ha pupuk SP-36 dan 185 kg/ha pupuk KCl. Lahan B - 107,6 kg/ha pupuk urea, 25,67 kg/ha pupuk SP-36, dan 185 kg/ha pupuk KCl. Lahan C - 107,17 kg/ha pupuk urea, 80,28 kg/ha pupuk SP-36, dan 117,6 kg/ha pupuk KCl.

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.

Abstract

The detrimental ecological impact of unauthorized gold mining in Indonesia is significantly profound, notably apparent in the nutrient-deficient, sandy soils with low pH resulting from the process. These conditions contribute to considerable land productivity decline, especially in West Kalimantan. In response to this challenge, the current study proposes an inventive approach for soil reclamation using red mud residue, derived from bauxite ore extraction, and cow manure as restorative elements. This research delves into a novel soil restoration technique that employs red mud waste (a residual from ore refinement) in conjunction with cow manure as ameliorative agents. A distinct amalgamation of 0.2 kg of red mud and 3 kg of cow manure (T2R3) showcased superior results. The incorporation of this blend resulted in a significant increase in soil pH by 0.93 units, an increase in macronutrient content ranging from 82.84%-503.07%, and plant growth (plant height and stem diameter) increased between 32.85%-54.31% in the treatment with 0.2 kg of red mud and 3 kg of cow manure (T2R3) compared to the lower treatment of 0.1 kg of red mud and 1 kg of cow manure (T1R1). These changes were evident, indicating improved soil fertility and the potential for increased crop yield
